I am using a Gridview in my application which contains button field as below.
<asp:GridView ID="grvAccrualData" runat="server" AutoGenerateColumns="False" ForeColor="Black" Font-Names="Arial"
BackColor="#B10633" __designer:wfdid="w9" AllowPaging="True" Width="100%" OnRowCommand="grvAccrualData_RowCommand">
<PagerSettings FirstPageText="<< First" LastPageText="Last >>"
Mode="NextPreviousFirstLast" NextPageText="Next >" PreviousPageText="Prev <">
</PagerSettings>
<FooterStyle BackColor="#B10633" Font-Bold="True" ForeColor="White"></FooterStyle>
<RowStyle Font-Names="Arial" Font-Size="8pt" HorizontalAlign="Left" VerticalAlign="Middle" BackColor="Ivory" />
<Columns>
<asp:BoundField DataField="AccrlHeaderAccrualNo" HeaderText="Accrual Number">
<ItemStyle HorizontalAlign="Left" VerticalAlign="Middle"></ItemStyle>
</asp:BoundField>
<asp:ButtonField ButtonType="button" CommandName="AccrualDetail" HeaderText="Debit Generation" Text="Account" />
</Columns>
<PagerStyle HorizontalAlign="Center" BackColor="#B10633" ForeColor="Black"></PagerStyle>
<HeaderStyle BackColor="#B10633" Font-Names="Arial" Font-Size="8pt" ForeColor="White">
</HeaderStyle>
<AlternatingRowStyle BackColor="#FFC0C0"></AlternatingRowStyle>
</asp:GridView>
And my server side code is :
protected void grvAccrualData_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "AccrualDetail")
{
}
}
In this server code I want to call a form or a webpage on button click.
Use
Response.Redirect("~/WebPage.aspx");
Or if you want to pass parameter along with this means then use QueryString.

I am using Visual Studio 2015 and Entity Framework 6. I have a gridview displaying orders from a database. However, I need a user to be able to click a row and be taken to another page for editing that row after a dialog box confirmation.
This is what I have:
<asp:GridView ID="gridOrders" runat="server" Height="184px" Width="1359px" AutoGenerateColumns="false"
AllowSorting="true" >
<HeaderStyle Font-Bold="true" Font-Size="16pt" BackColor="#cc0000" ForeColor="Black" />
<RowStyle Font-Size="12pt" BackColor="#afadad" ForeColor="White"/>
<AlternatingRowStyle BackColor="#afadad" ForeColor="White" />
<Columns>
<asp:CommandField HeaderText="" SelectText="CANCEL ORDER" ShowSelectButton="true" ControlStyle-ForeColor="White" />
<asp:BoundField HeaderText="First Name" DataField="FirstName" SortExpression="FirstName" />
How do I make the row selection to another page happen with a dialog that asks user if they are sure?
Change your aspx page with the below code
<asp:GridView ID="gridOrders" runat="server" Height="184px" Width="1359px" AutoGenerateColumns="False"
AllowSorting="True">
<HeaderStyle Font-Bold="true" Font-Size="16pt" BackColor="#cc0000" ForeColor="Black" />
<RowStyle Font-Size="12pt" BackColor="#afadad" ForeColor="White" />
<AlternatingRowStyle BackColor="#afadad" ForeColor="White" />
<Columns>
<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:LinkButton ID="lnkCancelOrder" runat="server" OnClientClick="return confirm('Are you sure to redirect?')" OnClick="lnkCancelOrder_Click" CausesValidation="False" CommandArgument='<%#Eval("OrderID") %>' CommandName="Select" Text="CANCEL ORDER"></asp:LinkButton>
</ItemTemplate>
<ControlStyle ForeColor="White" />
</asp:TemplateField>
<asp:BoundField HeaderText="First Name" DataField="FirstName" SortExpression="FirstName" />
</Columns>
</asp:GridView>
Write the c# code as follows
You can redirect to another page and pass the orderID as QueryString, and retrieve the complete order information by orderID and show that in an edit mode form
protected void lnkCancelOrder_Click(object sender, EventArgs e)
{
LinkButton lnk = sender as LinkButton;
string orderID = lnk.CommandArgument;
Response.Redirect("AnotherPage.aspx?orderId="+orderID);
}
Write under the <asp:TemplateField> of Gridview as
<asp:LinkButton ID="anchrTag" runat="server" PostBackUrl="Your edit page url" OnClientClick="return confirm('Are u sure to leave this page and want to go for edit?');">Edit</asp:LinkButton>
So there's not much to explain, I have a GridView and I put a Delete button which asks if you're sure you want to delete when you click it. I'm using VisualStudio2012 and I've done this in many other pages but I've never gotten this problem.
GridView:
<asp:GridView ID="MaintenanceTable" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" DataKeyNames="Maintenance_ID" DataSourceID="MaintDataSource" EmptyDataText="There are no data records to display." BackColor="White" BorderColor="#999999" BorderStyle="None" BorderWidth="1px" CellPadding="3" GridLines="Vertical" Width="1000px">
<AlternatingRowStyle BackColor="#DCDCDC" />
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton runat="server" ID="DeleteButton" Text="Delete"
CommandName="delete"
OnClientClick="if (!window.confirm('Are you sure you want to delete this item?')) return false;" />
</ItemTemplate>
</asp:TemplateField>
<asp:CommandField ShowEditButton="True" ShowSelectButton="True" />
<asp:BoundField DataField="Maintenance_ID" HeaderText="Maintenance_ID" InsertVisible="False" ReadOnly="True" SortExpression="Maintenance_ID" />
<asp:CheckBoxField DataField="Status" HeaderText="Status" SortExpression="Status" />
<asp:BoundField DataField="Date" HeaderText="Date" SortExpression="Date" />
<asp:BoundField DataField="Notes" HeaderText="Notes" SortExpression="Notes" />
</Columns>
<EditRowStyle BackColor="#999999" />
<FooterStyle BackColor="#CCCCCC" ForeColor="Black" />
<HeaderStyle BackColor="#34397D" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" />
<RowStyle BackColor="#EEEEEE" ForeColor="Black" />
<SelectedRowStyle BackColor="#008A8C" Font-Bold="True" ForeColor="White" />
<SortedAscendingCellStyle BackColor="#F1F1F1" />
<SortedAscendingHeaderStyle BackColor="#0000A9" />
<SortedDescendingCellStyle BackColor="#CAC9C9" />
<SortedDescendingHeaderStyle BackColor="#000065" />
</asp:GridView>
This really is the only code I've added in terms of deleting in my GridView:
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton runat="server" ID="DeleteButton" Text="Delete"
CommandName="delete"
OnClientClick="if (!window.confirm('Are you sure you want to delete this item?')) return false;" />
</ItemTemplate>
</asp:TemplateField>
You need to add the following code:
protected void MaintenanceTable_RowCommand(object sender,
GridViewCommandEventArgs e)
{
if (e.CommandName == "Delete")
{
// get the maintenanceId of the clicked row
int maintenanceId = Convert.ToInt32(e.CommandArgument);
// Delete the record
DeleteRecordByID(maintenanceId);
// Implement
}
}
Just incase, make sure you use "Delete" not "delete".

On PageIndexChanged
protected void gvGRNListAll_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gvGRNListAll.PageIndex = e.NewPageIndex;
SearchData();
gvGRNListAll.PageIndex = 0;
}
Searchdata Code :
public void SearchData()
{
DataTable dtGRN = objBAL.FilterGRNScannedList("filterGRNScannedList", suppliercode, grnno, locationcode, Fromdate, Todate, "");
gvGRNListAll.DataSource = dtGRN;
gvGRNListAll.DataBind();
}
Onclick event Code :
if (sender is LinkButton)
{
GridViewRow gvrCurrent = ((LinkButton)sender).NamingContainer as GridViewRow;
hdnGRNNo = (HiddenField)gvrCurrent.FindControl("hdnGRNNo");
hdnStore = (HiddenField)gvrCurrent.FindControl("hdnStoreCode");
gvGRNListAll.Rows[gvrCurrent.RowIndex].BackColor = System.Drawing.Color.Empty;
gvGRNListAll.Rows[gvrCurrent.RowIndex].BackColor = System.Drawing.ColorTranslator.FromHtml("#D8D8D8");
if (hdnGRNNo != null && hdnStore != null)
{
GetGRNListForNo(hdnGRNNo.Value, Convert.ToInt32(hdnStore.Value));
}
}
on RowDataBound do something like below
private void gvGRNListAll_RowDataBound(Object sender, GridViewRowEventArgs e)
{
if (e.Row.Cells[6].Text == "") // here add the cell no at which the row is coming blank.
e.Row.Visible = false;
}
Hope it helps
I have a gridview in the front end showing 4-5 columns. Need to hide one of the column when the values are NULL.

If I want to hide StoreName column from code-behind. How to achieve that ?
You can Use RowDataBound Event of GridView
protected void gridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
string val = e.Row.Cells[0].ToString(); //check first cell value
if(string.IsNullorEmpty(val) )
{
gvSearchEngine.Columns[0].Visible = false; //Hides First Column
}
}
}
Yes, you can dynamically create the boundfield values
from code behind based on your requirment
follow this link
add boundField to gridview in codebehind file C#
try e.Row.Cells[0].Controls[0].Visible = false;
I hav a gridview inside a usercontrol
<asp:GridView ID="grdMissingFilterData" runat="server" AllowPaging="True" Width="100%"
AllowSorting="True" AutoGenerateColumns="False" GridLines="None"
PageSize="30" OnPageIndexChanging="grdMissingFilterData_PageIndexChanging">
<Columns>
<asp:BoundField DataField="Varenummer" HeaderText="Varenummer" ItemStyle-Width="25%" >
<ItemStyle Width="25%" />
</asp:BoundField>
<asp:BoundField DataField="Varenavn" HeaderText="Varenavn" ItemStyle-Width="15%" >
<ItemStyle Width="15%" />
</asp:BoundField>
<asp:BoundField DataField="Producentvarenummer" HeaderText="Producent varenummer" ItemStyle-Width="15%" >
<ItemStyle Width="15%" />
</asp:BoundField>
</Columns>
<AlternatingRowStyle CssClass="altrow" />
<PagerSettings FirstPageText="First" LastPageText="Last" PageButtonCount="50" />
<EmptyDataTemplate>
There is no data available to display!
</EmptyDataTemplate>
<PagerStyle CssClass="pager" />
</asp:GridView>
and code in postback
if (!Page.IsPostBack)
{
BindData();
}
then i had a PageIndexChanging event which never fires when i click on paging.
protected void grdMissingFilterData_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
grdMissingFilterData.PageIndex = e.NewPageIndex;
BindData();
}
can any one give me any possible reasons?
This may be probably an issue with your user control not about gridview.
Focus on that part
