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...
View 2 RepliesGridview is not working when firing event from templatefield linkbutton
[Code]....
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.
How 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).
Im using a LINQDataSource to populate a GridView of Universities.
Each University has an associated State, which is in another table and associated by a foreign key (StateID).
I have a TemplateField in the GridView so that when you view it normally it displays the StateName which comes from the State table and when you edit it shows a DDL populated with everything from the State table.
[Code]....
If I debug, inside of RowUpdating, GridViewUpdateEventArgs.NewValues doesnt even have a key for State.

<asp:TemplateField HeaderText="Phrase">
<ItemTemplate>
<asp:TextBox ID="phraseTextBox" runat="server" Text='<%# Bind("Phrase") %>'/>
</ItemTemplate>
</asp:TemplateField>
But after changing the content of any TextBox in column "Phrase" my List doesn't reflect that changes.

sample:
for (int j = 0; j < this.Columns.Count; j++)
{
BoundField bf;[code]....
but i can access control in the templateField.such as ColumnBound.
sample: <asp:Label ID="Label1" runat="server" Text='<%# Bind("Name") %>'></asp:Label>
i want access "Name" (Bind ("Name") or Eval ("Name")) .how can i?there is a point: i dont now what is the ID (in this case "Label1") of control in templatefield.

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 might just be misunderstanding, but as far as I can tell they don't really help me. How do I get this to go away without setting enableEventValidation="false"?

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.

I was wondering if there is any way to view an sql statement that is created by a templateField Gridview when updating? I had my Gridview working properly then I changed my update statement to update less fields and I changed a couple more things on the page and now I don't know what broke it. The error I'm getting is
"System.Data.OleDb.OleDbException: Syntax error in UPDATE statement."
When I searched for this error it said to debug it but all that happens when I do that is visual studio tells me there were errors because it couldn't find my header, which it does find when it runs regularly so this isn't the problem.
