I believe my SQL statement is sound. UPDATE [062610] SET abc = @abc FROM [062610] WHERE (dayID = @dayID) I cant seem to get my stupid variable @abc to sync with my GridView update command. I understand that I can let the GridView take care of my editting for me without having to write any code. But, I am running multiple tables and will be eventually needing to do this manually. Or at least as far as I know.

I have a page for a product listing using a datalist control. I have customized the item template and added a link button that says Click to Order. I then databound that linkbutton with the onclientclick to the "ProductID" field, but I would like to set a variable or use some method of getting the productID of which item they clicked so I can add that product to an order. I cannot understand how to find out which item was clicked though... here is my code:

I want to create a link button with following code. However, this linkbutton doesnt work correctly: when I clicked it, it cannot go to the target url and will cause an exception.
<asp:LinkButton PostBackUrl='LearnPage.aspx?cid=<%#Eval("cid") %>' runat="server"><%# Eval("cname")%></asp:LinkButton>
(The linkbutton is one column of a grid view)
Debugging the code, I found that the value of cid is not parsed to the url. Actually, this code <%#Eval("cid") %> is not recognized as a variable, the target url appears to be LearnPage.aspx?cid=<%# Eval("cid") %> instead of LearnPage.aspx?cid=VALUE.
Nested GridView Control returns "Object variable or With block variable not set" when outer GridView returns rows.
The Nested GridView Control works as long as the outer GridView returns rows, the following code works: [Code]....
Object variable or With block variable not set.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Source Error:
Line 118: If e.Row.RowType = DataControlRowType.DataRow Then
Line 119: Dim myStatus_ID As SqlDataSource = CType(e.Row.FindControl("sqlDeviceStatusAssign"), SqlDataSource)

Line 121: myStatus_ID.SelectParameters(0).DefaultValue = e.Row.DataItem("Status_ID")
Line 122: End If
I have tried checking for IsDbNull and checking to see if a label exists in a given row. This code *If Not e.Row.DataItem("Status_ID") Is Nothing Then* appears to do nothing.Same with the following:
*Dim localLblItemReference As Label = CType(e.Row.FindControl("lblItemReference"), Label)
*If Not localLblItemReference Is Nothing Then

To further clarify my question above, I am looking for a method to detect e.Row.DataItem("Status_ID") is nothing/null due to the outer GridView returning 0 results in a query.I have a (Outer) GridView Control with another GridView Control inside of a template field with it's associated SqlDataSource control.
In the "Protected Sub GridViewReport_RowCreated", I provide the Select Parameter for the associated SqlDataSource with the DataItem row value.When the (Outer) GridView Control does not return any rows, the "e.Row.DataItem("Status_ID")" throws a:
Exception Details: System.NullReferenceException: Object variable or With block variable not set.

If the user clicks on Inbox or Sent links, the inbox or sent tables with appropriate content taken from Message_Inbox database table should be shown on right. use asp.net panel controls hide/show to show/hide these tables. when user clicks on message subject link in these tables, the read-only view message page should be shown.
If the user clicks on Drafts link, the drafts tables with appropriate content taken from Message_Inbox database table should be shown on right.when user clicks on message subject link in these tables, the pre-composed form should be shown. the user should allowed to send or save this message.

I have a Gridview of a database which displays the PDF files which I have uploaded onto the website.
I want to add a link/button to each record so that when I click it it opens the PDF file in Adobe Acrobat.
here's my url: http://nathan/mail/incomingmail.aspx?dc=8250&bg=-617370170
gridview code:
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False"

On Page1 of a project, I have a Gridview showing a table of customer names (showing CustID, CustName, CustJoinDate). When I click on a record, I have passed a querystring to Page2 showing an address table for that customer. This part works for me.
The SQL statement in simply: Select * from CustAddress where CustID = @cust
What I would like to do though, is capture that @cust to a session variable so that I can use it later on.
How can one disable a Link Button in gridview. In gridview, I had defined linkbutton as :
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="lnkbtndownload" runat="server" CssClass="Links" CommandName="DownloadPdf" CommandArgument='<%#Eval("Client_ID")%>'>Download</asp:LinkButton></td>
</ItemTemplate>
</asp:TemplateField>
I Want to be able to replace this bitfield:
<asp:TemplateField HeaderText="Banned" SortExpression="bitBanned">
<ItemTemplate>
<asp:Label ID="Label5" runat="server" Text='<%# ShortDisplay("bitBanned") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
with a link in my gridview that toggles the bit with a method from my dblayer
The ShortDisplay() method seen above looks like this:
protected string ShortDisplay(string strPerm)
{
string result = string.Empty;
if (Eval(strPerm) != null && (string.Compare(Eval(strPerm).ToString(), "True", 0) == 0))
result = "Yes";
else
result = "No";
return result;
}
As you can see it returns just a "yes" or "no", would like it to be a link when the bit is "Yes"
Is there a way based on the current user that when the page loads that the Delete option on the gridview is disabled?
