Persisting Checkbox state while paging in SPGridView - asp.net

Suppose I have created a spgridview with the following code.
<SharePoint:SPGridView ID="spgridList" Visible="false" runat="server" AutoGenerateColumns="false"
Width="100%" AllowPaging="true" AllowSorting="true" AllowFiltering="true" PageSize="5"
OnPageIndexChanging="spgridList_PageIndexChanging" HeaderStyle-BackColor="Red"
onrowdatabound="spgridList_RowDataBound" onrowcommand="spgridList_RowCommand">
<PagerStyle CssClass="ms-descriptiontext" />
<HeaderStyle BackColor="Blue" ForeColor="Black" Font-Bold="true" />
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox CssClass="chkbox" Checked="false" ID="chkField" AutoPostBack="true"
OnCheckedChanged="chkField_CheckedChanged" runat="server" />
</ItemTemplate>
<HeaderTemplate>
<asp:CheckBox ID="chkSelectAll" runat="server" AutoPostBack="true" OnCheckedChanged="chkAll_CheckedChanged" />
</HeaderTemplate>
</asp:TemplateField>
</Columns>
</SharePoint:SPGridView>
To persist the checkbox states between pagebacks ,currently i am using session states.It has some draw backs.Now how can I persist the checked states,when the user manually checks all the checkboxes,how can i make a check on the header checkbox?Provide some links

How about emulating it like a select CheckBox but disabling the focus of the row?
Selection of the rows is maintained across pages.

Bind Gridview Datasource with Linq (asp.net)

Basically, what I want to do is to bind a Linq query to the datasource of a gridview. Here is my code so far :
ddgDossiers.DataSource = (From c In dbConnection.Campaigns.AsQueryable Select c).ToList
ddgDossiers.DataBind()
It compiles and doesn't complain of anything.
<asp:GridView ID="ddgDossiers" runat="server" CellPadding="0" CellSpacing="0" AllowSorting="True"
AutoGenerateColumns="False" EnableViewState="True" AllowPaging="True" PageSize="35"
PagerStyle-HorizontalAlign="Right" PagerStyle-Mode="NumericPages" PagerStyle-Position="TopAndBottom"
BorderWidth="1" GridLines="Both" BorderColor="#000000" CssClass="mGrid" PagerStyle-CssClass="pgr">
<PagerSettings Position="TopAndBottom" />
<Columns>
<asp:TemplateField Visible="false" HeaderText="UniqueID" ItemStyle-HorizontalAlign="left"
HeaderStyle-HorizontalAlign="Center" ItemStyle-Width="1%" HeaderStyle-Width="1%"
HeaderStyle-CssClass="GridTitle" ItemStyle-CssClass="rowReport" SortExpression="UniqueId">
<ItemTemplate>
<asp:Label ID="lblUniqueID" runat="server" Text='<%#Container.DataItem("Campaign.CampaignId").ToString%>' />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
The error is pointing on this line :
<asp:Label ID="lblUniqueID" runat="server" Text='<%#Container.DataItem("CampaignId").ToString%>' />
And saying : No default member found for type 'Campaign'.
Is there anything to do with that? Thanks in advance.
change line
Text='<%#Container.DataItem("Campaign.CampaignId").ToString%>'
To
Text='<%# DataBinder.Eval(Container.DataItem, "CampaignId") %>'

Grid display changes on re binding the grid

I have a grid on my aspx page.I have set its font property to small..
On page load it is all okay..
but once I perform some action like a delete activity given in the grid itself..and the grid is bound again by recalling the method to bind grid..
the grid seems to be bigger with big fonts.
What could be the trouble?

</Columns>
</asp:GridView>
Did you try specifying the font color in ItemTemplate ? Its worth a try.

ASP.NET GridView Display TextBox if Row is Empty

My GridView is DataBound to a SQL data connection which should almost always return data. So using an EmptyDataTemplate does not help me because the GridView should never be empty. But I want the first few rows to be editable so the user can add new information to the GridView. So I've crafted my Select statement to always come back with 3 empty rows. I want those rows to contain TextBoxes instead of Labels. But this:
<asp:GridView ID="GridView1" runat="server"
AutoGenerateColumns="False" DataSourceID="SqlDataSource1"
BorderColor="White" BorderStyle="Solid"
onselectedindexchanged="GridView1_SelectedIndexChanged" ShowFooter="False"
ViewStateMode="Disabled">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<input type="checkbox" id ="CheckBox1" class="checkbox" />
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>
<asp:TemplateField HeaderText="Serial" SortExpression="Serial">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("Serial") %>'></asp:Label>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>
<asp:TemplateField HeaderText="Model" SortExpression="Model">
<EditItemTemplate>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%# Bind("Model") %>'></asp:Label>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>
<asp:TemplateField HeaderText="From Store">
<ItemTemplate>
<asp:DropDownList ID="DropDownList1" runat="server" CssClass="dropdownlist"
DataSourceID="SqlDataSource2" DataTextField="Store"
SelectedValue='<%# Bind("Store") %>'>
</asp:DropDownList>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>
<asp:TemplateField HeaderText="To Store">
<ItemTemplate>
<asp:DropDownList ID="DropDownList2" runat="server" CssClass="dropdownlist"
DataSourceID="SqlDataSource2" DataTextField="Store">
</asp:DropDownList>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>
</Columns>
<FooterStyle HorizontalAlign="Center" ForeColor="White" BorderColor="White" BorderStyle="Solid" />
<HeaderStyle ForeColor="White" BorderColor="White" BorderStyle="Solid" />
<RowStyle BorderColor="White" BorderStyle="Solid" ForeColor="White" />
</asp:GridView>
Produces this:
Where the first 3 rows have uneditable Labels rather than TextBoxes. Is what I want to do possible?
In your template fields add <FooterTemplate></FooterTemplate> This makes the footer row of your gridview a place where you can add new rows. Of course you will need to put items inside the <FooterTemplate>, but the work the same as your <ItemTemplates
So to serve my specific purpose, I decided just to create a table separate from this with an empty row with textboxes. Then a button that used JQuery to take the values from that table to append them into the uneditable row in the DataGrid. Removed the header row from the DataGrid so it all looked like the same table.

asp.net one more updatepanel is not working

I added 3 updatepanel on a aspx page.Two updatepanel includes gridview.And i make gridview paging.two buttons fill this gridviews when clicked.I set both of them triggers and conditional state.Third updatepanel includes textbox.And i set updatemode conditional,triggers third button.
That my question,when i click firstly third button i select checked datafield from gridview,run succesfully.
But when i click after one clicked,third updatepanel and gridview paging is not working.

How can i fix.
Logic is .. If you have one or more update panel in the same page then properties of all update panel should be same such as if update panel data are dependency on each other
Update Mode : Always
EnableViewState : true(if you are using it)
Or you can explicitly update the Update panel when mode is conditional
Let us say you have two update panel like up1 and up2.
You have placed the label in the up1 and the other form or button placed in the up2.
Now on the click event in the up2, label placed in the up1 should be updated without loading the full page. Set the following stuffs
Set EnableParitialRendering ='True'(Script Manager)
Set Update Mode :Conditional(up1)
Set Update Mode : Always (up2). All set up done here. On click of a button in the up2, do your work and call up1.Update(); That's all.

DomEvent. AddHandler

I am facing little issue in my web application in asp.net.
i am receiving the below error :
Error: Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method.
I have used Updatepanel and this error occurs when i try to do some 2-3 actions very quickly.
and when next time i try to do take some action my web application just hungs up.
Please suggest.
Thanks
In my case this was caused by having the 'Close' control within an Update Panel in the Modal Popup. I fixed it by creating a 'dummy' button outside of the Update Panel, and setting it as the 'CancelControlID' in the MPE attributes:
<asp:Button ID="btnDummyCloseWindow" runat="server" Style="visibility: hidden"/>
<ajaxToolkit:ModalPopupExtender ID="mpeWindow" runat="server" PopupControlID="pnlWindow"
TargetControlID="btnDummyOtherButton" BackgroundCssClass="modalBackground"
DropShadow="false" CancelControlID="btnDummyCloseWindow" />
You'll need to make sure the close button that is present within your Update Panel has actions assigned to it to close the window (e.g. mpeWindow.hide()).
It's also worth noting that I was also making use of the TargetControlID 'fix' too, where a dummy button is referenced, so ignore the TargetControlID attribute there.
I've solved the problem setting ScriptMode property of ScriptManager to Release instead of Debug
By default ScriptManager is set to Debug mode.
I had the same problem and solved by placing the ModalPopupExtender or the user control that uses ModalPopupExtender inside an update panel.
Which ever way you want to look at it, the problem is inherit in what I believe is a bug in AJAX.
The only way I was able to resolve this was to control your Sorting or Paging on the server side where you control or more specifically refresh the UpdatePanel along with making sure the ModalPopup has been kept visible!
The reason for the error is really because once you do a sort of page change on a GridView that's inside an UpdatePanel, the controls have been "lost" to the UpdatePanel.
A better explanation is here.

The major point of the code above is that I have a very deep GridView inside an UpdatePanel that's inside a ModalPopUp.
Now look at what I have inside that GridView:
OnPageIndexChanging
and
OnSorted
Inside the GridView, there is another ModalPopup and TextBox. Ignore that. That's only so the user can see the comments from the student's contact log as another popup window.
So if we now go to the code behind for the above two events:
protected void gvWEFContactLog_Sorted(object sender, EventArgs e)
{
GridView gvWEFCL = (GridView)sender;
GridViewRow gvRow = (GridViewRow)gvWEFCL.NamingContainer;
UpdatePanel upWEF1 = (UpdatePanel)gvRow.FindControl("upWEF1");
if (upWEF1 != null) upWEF1.Update();
AjaxControlToolkit.ModalPopupExtender mpeWEF = (AjaxControlToolkit.ModalPopupExtender)gvRow.FindControl("mpeWEF");
if (mpeWEF != null) mpeWEF.Show();
}
protected void gvWEFContactLog_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView gvWEFCL = (GridView)sender;
GridViewRow gvRow = (GridViewRow)gvWEFCL.NamingContainer;
UpdatePanel upWEF1 = (UpdatePanel)gvRow.FindControl("upWEF1");
if (upWEF1 != null) upWEF1.Update();
AjaxControlToolkit.ModalPopupExtender mpeWEF = (AjaxControlToolkit.ModalPopupExtender)gvRow.FindControl("mpeWEF");
if (mpeWEF != null) mpeWEF.Show();
}
Notice that I am not actually controlling the sorting or the paging itself. I am only forcing the GridView to call upon the main UpdatePanel (upWEF1) to refresh itself via an Update() call. The next step is to grab the ModalPopup I want to keep visible and re-Show() it!
And that's all there is to it!
I am sure there is a cleaner solution using JavaScript itself, but for me this avoids that dread meaningless error and I have a clean set of popups and update panels that can handle both hotlinks, sorting and paging as I want the GridView to perform!
