I am using a button and a grid inside the update panel, when user clicks on that button the result is updated in this grid
But this button is not raising any click event due to which code is not able to hit code behind.
following is the HTML code I am using
<div id="DivGridPendingCRSeeMore" class="editableDialogContentPanel" style="display: none">
<asp:UpdatePanel ID="RecentGridPendingCRSeeMore" runat="server">
<ContentTemplate>
<asp:Button ID="ButtonRecentGridPendingCRSeeMoreSearch" runat="server" Text="Search"
OnClick="ButtonRecentGridPendingCRSeeMoreSearch_Click" />
<asp:GridView ID="GridPendingCRSeeMore" runat="server" AllowSorting="true" AllowPaging="true"
PageSize="20" AutoGenerateColumns="false" PagerSettings-Visible="false" RowStyle-CssClass="gridDataRow"
CssClass="grid">
<Columns>
<asp:HyperLinkField HeaderText="Request ID" DataTextField="Request_ID" SortExpression="Request_ID"
DataNavigateUrlFields="Request_ID" DataNavigateUrlFormatString="ChangeRequestDetails.aspx?RequestID={0}"
HeaderStyle-HorizontalAlign="Left" />
<asp:BoundField HeaderText="Territory ID" DataField="Territory_ID" SortExpression="Territory_ID"
HeaderStyle-HorizontalAlign="Left" />
<asp:BoundField HeaderText="Submitted By" DataField="Submitted_By_Name" SortExpression="Submitted_By_Name"
ItemStyle-Wrap="false" HeaderStyle-HorizontalAlign="Left" />
<asp:BoundField HeaderText="Owner" DataField="owner_name" SortExpression="owner_name"
ItemStyle-Wrap="false" HeaderStyle-HorizontalAlign="Left" />
<asp:BoundField HeaderText="Type" DataField="Request_Type" SortExpression="Request_Type"
ItemStyle-Wrap="false" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" />
<asp:BoundField HeaderText="Status" DataField="CR_Status" SortExpression="CR_Status"
ItemStyle-Wrap="false" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" />
<asp:BoundField HeaderText="Date Submitted" DataField="Submit_Date" SortExpression="Submit_Date"
DataFormatString="{0:MM/dd/yyy}" HtmlEncode="false" HeaderStyle-HorizontalAlign="Center"
ItemStyle-HorizontalAlign="Center" />
<asp:BoundField HeaderText="Description (ID or Name)" DataField="Description" SortExpression="Description"
ItemStyle-Wrap="false" HeaderStyle-HorizontalAlign="Left" />
</Columns>
</asp:GridView>
<UC1:PagerControl ID="HomePendingCRPager" runat="server" />
</ContentTemplate>
</asp:UpdatePanel>
</div>
Following is the code behind handler
Protected Sub ButtonRecentGridPendingCRSeeMoreSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonRecentGridPendingCRSeeMoreSearch.Click
End Sub
Add Trigger in UpdatePanel like this
<Triggers>
<asp:AsyncPostBackTrigger ControlID="ButtonRecentGridPendingCRSeeMoreSearch" EventName="Click"/>
</Triggers>

I have what seems on the surface a really simple requirement. I want to update a label with a value from the data source when a user clicks a field in a datagrid control.
My page has an SqlDataSource control on it, which returns (for example) 6 columns. I display 5 of them in the datagrid, and want the sixth column shown in a label when the user selects a row.
I have tried various things, with limited success. One way I was convinced would work was to include the column in the datagrid, but set it to Visible="false". However, it turns out that if you do this, the value of row(5).text is ""... Not what I expected.
Any quick way of achieving this?
-- EDIT - Added in code samples --
<asp:GridView ID="gridL250Tickets" runat="server" AutoGenerateColumns="False" BackColor="White" BorderColor="#999999" BorderStyle="Ridge" BorderWidth="2px" Caption="Last 250 Tickets" CellPadding="3" CellSpacing="1" DataKeyNames="TICKETID" DataSourceID="sqlSlxL250Tickets" AllowPaging="True" AllowSorting="True" HorizontalAlign="Center" Width="75%" PageSize="6">

<asp:BoundField DataField="notes1" HeaderText="Notes" SortExpression="notes1" Visible="False" />
<asp:BoundField DataField="USERNAME" HeaderText="Ass. To" SortExpression="USERNAME" />
<asp:BoundField DataField="notes" HeaderText="Notes - l" SortExpression="notes" Visible="false" />

</asp:GridView>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
VB Code:
Private Sub gridL250Tickets_SelectedIndexChanged(sender As Object, e As EventArgs) Handles gridL250Tickets.SelectedIndexChanged
Dim row As GridViewRow = gridL250Tickets.SelectedRow
Label1.Text = row.Cells(9).Text
End Sub
You could use a hidden <asp:TemplateField> with a label instead. I tested that out and it seems to work.
<asp:GridView ID="gridL250Tickets" runat="server" AutoGenerateColumns="False" BackColor="White" BorderColor="#999999" BorderStyle="Ridge" BorderWidth="2px" Caption="Last 250 Tickets" CellPadding="3" CellSpacing="1" DataKeyNames="TICKETID" DataSourceID="sqlSlxL250Tickets" AllowPaging="True" AllowSorting="True" HorizontalAlign="Center" Width="75%" PageSize="6">
<Columns>
<asp:CommandField ShowSelectButton="True" />
<asp:BoundField DataField="SUBJECT" HeaderText="Ticket" SortExpression="SUBJECT" />
<asp:BoundField DataField="RECEIVEDDATE" DataFormatString="{0:d}" HeaderText="Received" SortExpression="RECEIVEDDATE" />
<asp:BoundField DataField="COMPLETEDDATE" DataFormatString="{0:d}" HeaderText="Completed" SortExpression="COMPLETEDDATE" />
<asp:BoundField DataField="AREA" HeaderText="Area" SortExpression="AREA" />
<asp:BoundField DataField="CATEGORY" HeaderText="Category" SortExpression="CATEGORY" />
<asp:BoundField DataField="ISSUE" HeaderText="Issue" SortExpression="ISSUE" />
<asp:BoundField DataField="notes1" HeaderText="Notes" SortExpression="notes1" Visible="False" />
<asp:BoundField DataField="USERNAME" HeaderText="Ass. To" SortExpression="USERNAME" />
<%--<asp:BoundField DataField="notes" HeaderText="Notes - l" SortExpression="notes" Visible="false" />--%>
<asp:TemplateField Visible="false">
<ItemTemplate>
<asp:Label ID="lblNotes" runat="server" Text='<%# Eval("notes") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
//...
Then just find the label in your event and use its text.
Private Sub gridL250Tickets_SelectedIndexChanged(sender As Object, e As EventArgs) Handles gridL250Tickets.SelectedIndexChanged
Dim row As GridViewRow = gridL250Tickets.SelectedRow
Dim lblNotes As Label = row.FindControl("lblNotes")
Label1.Text = lblNotes.Text
End Sub
Instead of setting Visible = "False", try setting the actual CSS of the given column. Display = "none", and switch it back when the grid control is clicked.
Something along the lines of lblNotes.Style.Item("display") = "none". You could also do that in the Javascript if you didn't want to have a pageback.
I have added a button for Print in my gridview table as follows
<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
AllowSorting="True" AutoGenerateColumns="False" DataKeyNames="ID"
DataSourceID="SqlDataSource2"
onselectedindexchanged="GridView1_SelectedIndexChanged" Width="522px">
<Columns>
<asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False"
ReadOnly="True" SortExpression="ID" />
<asp:BoundField DataField="Story_number" HeaderText="Story_number"
SortExpression="Story_number" />
<asp:BoundField DataField="Date" HeaderText="Date" SortExpression="Date" />
<asp:BoundField DataField="Memory_card" HeaderText="Memory_card"
SortExpression="Memory_card" />
<asp:BoundField DataField="Story_Name" HeaderText="Story_Name"
SortExpression="Story_Name" />
<asp:ButtonField ButtonType="Button" Text="print" />
</Columns>
</asp:GridView>
Please help me with the c# code for this button. When the button is pressed I need it to redirect to a page (print.aspx). I have been trying the following code but it does not work .Thanks in advance for your help.
Session["id"] = GridView1.SelectedRow.Cells[0].Text;
Response.Redirect("Print.aspx");
Instead of buttonField, use template field
<asp:TemplateField>
<ItemTemplate>
<asp:ImageButton ID="ButtonPrint" runat="server" CssClass="yourCssClassIsNeedIt" OnClick="printRegFunction"
CommandArgument='<%# Bind("id") %>' ImageUrl="images/button.png"/>
</ItemTemplate>
</asp:TemplateField>
your server code or behind code here:
protected void printRegFunction(object sender, ImageClickEventArgs e)
{
Session["id"] = ((ImageButton)sender).CommandArgument;
Response.Redirect("Print.aspx");
}
I'm building a GridView based on what is passed on the previous page querystring.
Is there a way to display a message saying 'no records found' if the GridView isn't populated? i.e. the query produces no records to populate the GridView.
code:
<div class="centergrid">
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1" CssClass="bookgridview">
<Columns>
<asp:TemplateField HeaderText="Choose">
<ItemTemplate>
<asp:HyperLink ID="lnkSelect" runat='server' NavigateUrl='<%# String.Format("~/bookingform.aspx?ID={0}", Eval("ScheduleId")) %>'>Book</asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="TName" HeaderText="Name" SortExpression="TName" />
<asp:BoundField DataField="SDate" HeaderText="Date" SortExpression="SDate" DataFormatString="{0:d}" />
<asp:BoundField DataField="STime" HeaderText="Time" SortExpression="STime" />
<asp:BoundField DataField="TPriceadult" HeaderText="Price (Adult)"
SortExpression="TPriceadult" DataFormatString="{0:C}" />
<asp:BoundField DataField="TPricesenior" HeaderText="Price (Student/Senior)"
SortExpression="TPricesenior" DataFormatString="{0:C}" />
<asp:BoundField DataField="TPricechild" HeaderText="Price (Child)"
SortExpression="Tpricechild" DataFormatString="{0:C}" />
<asp:BoundField DataField="TDuration" HeaderText="Duration"
SortExpression="TDuration" />
<asp:BoundField DataField="ScheduleId" HeaderText="ScheduleId"
SortExpression="ScheduleId" Visible="False" />
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:ChinatowndbConnString %>"
SelectCommand="SELECT * FROM [vwSchedule] Where TourId=#tid">
<SelectParameters>
<asp:QueryStringParameter DbType="Int32" Name="tid" QueryStringField="tourid" />
</SelectParameters>
</asp:SqlDataSource>
Is there a way to display a message saying 'no records found' if the
GridView isn't populated?
Yes, with the EmptyDataTemplate.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1" CssClass="bookgridview">
<emptydatarowstyle backcolor="LightBlue"
forecolor="Red"/>
<emptydatatemplate>
<asp:image id="NoDataImage"
imageurl="~/images/Image.jpg"
alternatetext="No Image"
runat="server"/>
No records found.
</emptydatatemplate>
<Columns>
<asp:TemplateField HeaderText="Choose">
<ItemTemplate>
<asp:HyperLink ID="lnkSelect" runat='server' NavigateUrl='<%# String.Format("~/bookingform.aspx?ID={0}", Eval("ScheduleId")) %>'>Book</asp:HyperLink>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="TName" HeaderText="Name" SortExpression="TName" />
<asp:BoundField DataField="SDate" HeaderText="Date" SortExpression="SDate" DataFormatString="{0:d}" />
<asp:BoundField DataField="STime" HeaderText="Time" SortExpression="STime" />
<asp:BoundField DataField="TPriceadult" HeaderText="Price (Adult)"
SortExpression="TPriceadult" DataFormatString="{0:C}" />
<asp:BoundField DataField="TPricesenior" HeaderText="Price (Student/Senior)"
SortExpression="TPricesenior" DataFormatString="{0:C}" />
<asp:BoundField DataField="TPricechild" HeaderText="Price (Child)"
SortExpression="Tpricechild" DataFormatString="{0:C}" />
<asp:BoundField DataField="TDuration" HeaderText="Duration"
SortExpression="TDuration" />
<asp:BoundField DataField="ScheduleId" HeaderText="ScheduleId"
SortExpression="ScheduleId" Visible="False" />
</Columns>
</asp:GridView>
Alternatively, you can use the built-in UI for the empty data row by setting the EmptyDataText property instead of this property.
I am really frustrated to find a solution for my scenario. I have two gird when First grid is used show the shop information and the second grid is used to edit the offers related to the shop information. When the users edit the second grid i will just update the text box values related to the grid selection row. in my code behind file i can see the data fetching from the grid and assigning into the text boxes but when the function call (imgEdit_click) finished the page does not show the values. Editing functionality can be done in many ways but my scenario is what i explained earlier . I have the checked page there is no Postback action has been called after the method I could not find the solution can anyone help me to figure it out.

Issue is because textboxes are out of Update Panel, So just put everything in update panel it will start functioning or just comment out update panel and then try the same thing.
I have a GridView which with a CheckBox in a TemplateField.
When I check something and hit the submit button, the items that I have checked are not check on the postback.
I tried using EnableViewState and that did not help.
How can this be fixed?
<asp:Button ID="btnSubmit" runat="server" Text="Submit" />
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:TemplateField HeaderText="SELECT">
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server"/>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="ICAO" HeaderText="ICAO" />
<asp:BoundField DataField="IATA" HeaderText="IATA" />
<asp:BoundField DataField="AIRPORT_NAME" HeaderText="AIRPORT NAME" />
<asp:BoundField DataField="CITY" HeaderText="CITY" />
<asp:BoundField DataField="COUNTRY" HeaderText="COUNTRY" />
<asp:BoundField DataField="REVISED_DATE" HeaderText="REVISED DATE" />
<asp:BoundField DataField="EMAIL_DATE" HeaderText="EMAIL DATE" />
</Columns>
</asp:GridView>
You need to override LoadViewState and SaveViewState methods to maintain the selection.
