[Code]....

I've turned up lots of advise from similar things, but not this exactly. I have a gridview with a templatefield that I want to call javascript from the OnClick event (or OnClientClick). When I try to compile, it complains saying my server tag isn't well formed. I'm sure that's a red herring...

How to show link view file in gridview using asp.net ....
I would like to call a method and pass a value to it on a link button autogenerated from the database in a templatefield inside a datagrid. I don't know much about delegates
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
..
((LinkButton)e.Row.Cells[(int)eMessage.TitleColumn].FindControl("btnMessageTitle")).Click += new EventHandler(delegate { viewSelectedMessage(this, 35); });
}
void viewSelectedMessage(object sender, int messageID)
{
lblTest.Text = messageID;
}
running the website and viewing the page source, I have realised that there is an OnClick event created for the linkbutton, however, this may be generated anyways. By running my solution using VS debugging, I can see that my method won't fire by clicking any of thos generated linkbuttons.
I have a GridView which contains a linkbutton in its templatefield. What I want to know is, when I click on the linkbutton, how can I get the text of the linkbutton into a string called 'name'?

View 3 RepliesHow can I hide a column in a GridView ?
I tried using the markup:
<asp:TemplateField ShowHeader="False" Visible='<%# MyBoolProperty %>' >
<ItemTemplate>
<asp:LinkButton ID="attachmentButton" runat="server" CausesV
CommandArgument='<%# bind("ID") %>' OnClientClick="$('#b
Text='<%$ Resources:Resource,Attachments %>'></asp:LinkB
</ItemTemplate>
but it didn't work and gave me the following error:
Databinding expressions are only supported on objects that have a DataBinding event.
System.Web.UI.WebControls.TemplateField does not have a DataBinding event.
I tried also to hide it programmatically, but seems I can't reach to the column by name (there's no name for TemplateField column).
This GridView contains a TemplateField with a LinkButton that displays a text value. When the link button is clicked, the code behind needs to capture the text value of the button, and then refresh the GridView with an asynchronous postback within the UpdatePanel and display the updated output.
The post-back event is occurring, and I'm able to capture the event in Visual Studio 2010 debugger. But, the screen contents do not change after this event occurs. No exception gets thrown, at least from what I can see in debugger.
Portions of the sanitized code appear below. The GridView actually appears on a page that contains 2 dropdown lists and 2 other GridViews. There is just one UpdatePanel on this page.
[Code]....
This is in the Code-Behind.

I can put a break point in the above method, and it is captured when the lnkHostName button is clicked. Stepping through the lnkHostName_Click() method, the ReloadPage() method successfully runs, then executes this method:
[Code]....
This runs successfully, and the DataSet which gets returned contains 1 row of data rather than several rows. This is what I expect to happen. Once the filter is selected in my test case just 1 row should get returned. The problem is that I don't see that output refreshed on the screen. The grdProcesses gridview continues to display the original dataset of several rows, rather than just one row of data. To additionally test this, I tried setting the visibility of grdProcesses to false within this method when the HostName had a value. Again, this ran without an error, but the GridView was still visible. And I also tested by updating the contents of a label with the HostName value. The new value was never displayed in the label. I also tried putting the lnkHostName button into the triggers, ala:
[Code]....
But the following exception gets thrown when that button is added, "A control with ID 'lnkHostName' could not be found for the trigger in UpdatePanel 'upMain'."
What's frustrating is that everything appears to run smoothly in debugger. But in reality the expected output never gets refreshed on the screen. Perhaps I need to use an alternate trigger in the AsyncPostBackTrigger. I'm open to using a command button or some other artifact.
I want to create simple rating page where player's place,name and rating is displayed. I've created database with ID,Name and Rating Columns, binded Gridview to this database and created TemplateField "Place". With following code I've created numbered list for Place:

I have a GridView, bound to a table (Meals) in a SqlDataSource.
Into that GridView, I have added a TemplateField, which contains a DropDownList (which displays the numbers 1 - 10, added manually; no Data Binding). And, I've added a ButtonField.
When I click the Button, I want the values of some of the GridView rows PLUS whatever value was selected in the DropDownList to be pulled out and stored in a second Sql table (Orders).
Pulling the rows bound to the SqlDataSource is easy but JavaScript is needed (I think) to pull the SelectedValue from the DropDownList. I understand women more than understand JavaScript (that's how little I know) and the code below has been kindly offered by another forum user who is at a loss, himself, now.
Here's the code and the error message I'm getting.

I have dynamically created my gridview in the codebehind.
All is working correctly.
I now need to dynamically add a TemplateField to the gridview and populate it with a Button.
I have the following code so far:

I'm relatively new to the VS environment. I'm using VS2010 Beta 2 with VB. I have a Gridview setup to pull a list of employees. Next to their name I have edit and delete icons. When I leave the icons as ButtonFields, they pass the DataKey value to my code behind perfectly. When I convert the ButtonFields to TemplateFields, they no longer pass the DataKey.

here is my code:

Though it is usually not a big deal to edit the source code to accomplish this, I am just curious if there is an easier way to reverse the conversion of a column to a TemplateField. The covnersion can be done by a simple click. Is there a similar click to reverse it?

I have a gridview with a DropDownList (contained in a TemplateField). I have set the OnSelectedIndexChanged event to a function called "ddlAgent_SelectedIndexChanged" This allows me to aquire when a user has changed the value for the dropdownlist. What I need to do is persist this newly selected value to the database for the gridview record. The problem I'm having is how to I get the datakeyNames value for that row? See code below!

<ItemTemplate>
<asp:DropDownList ID="ddlAgent" runat="server" AutoPostBack="False" OnSelectedIndexChanged="ddlAgent_SelectedIndexChanged">

Dim gvItems As DropDownList = CType(sender, DropDownList)
' Write the selected Agent ID to the Inquiry record.
'Dim ID As Integer = gvMaint.DataKeyNames(e.SelectedIndex).Value ' THIS FAILS BECAUSE
e.SelectedIndex is not part of System.EventArgs
End Sub
