I need the HeaderText of the templatefield to be set dynamically when I bind my grid. I get this error when I try to bind it the same way I would bind a control inside the template:
Databinding expressions are only supported on objects that have a DataBinding event...
I was wondering if anyone could give me an example of how to wire up a binding event for each templatefield in my grid?
I am trying to bind the datasource of a ddl which is located inside the EditTemplate of a TemplateField.When is the best time to bind this datasource (after loading grid, before editing, ? (Note: I must do this in code behind).I am currently trying to bind it on the edit command:

The issue is that the list retrieved from the LoadLists method is null when passing to the LoadList method where the datasource is bound.

I want to add an event handeler that tell me wich row had been selected and highlighted it too. I tried many times, but usually face this error "No overload for 'Grd_ServersInfo_CheckSelectedRow' matches delegate 'System.EventHandler' ". Could any one paste the right code lines to handel this event
Gridview 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.

View 4 RepliesI'm using VS2008. When a dataset is bound to the DataSource of a ListView, SelectedIndexChanged event does not fire. If I used DataSourceID instead, it has no problem. But SelectedIndexChanging event fires for both.
why and how I can get SelectedIndexChanged event fired when DataSource is used?
In ASP.net, I'm using textbox in templatefield's itemtemplate. I got it data-bound with no problem. But my problem is, I'm trying to write a function to find column index by its data-bounding table's column name.
Something like this :
foreach (DataControlFieldCell cell in row.Cells)
{
if (cell.ContainingField is BoundField)
{
if (((BoundField)cell.ContainingField).DataField.Equals(SearchColumnName))
{
return columnIndex;
}
}
else if (cell.ContainingField is TemplateField)
{
//Finding column name of data-bound textbox or dropdownlist ??
}
}
I have GridView bound to some List. In layout I created following template field:
<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.
I have an objectdatasource that accepts 1 parameter and fills a Gridview control.
Above this I have a details view control. Within one of the template fields I have placed a button. I have some code that captures this event.
What I'm trying to do is when a user clicks the button I would like to pass the contents of textbox (also held within the same template field) back into the SQL and refresh the Gridview control.
My ultimate goal is to allow the user to then edit the contents of the Gridview control.
I want to add one extra Template Field at runtime based on the User-Profile.

View 22 RepliesI 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 want to add two image button in the TemplateField.. and add it in the gridview.
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:
TemplateField tempField = new TemplateField();
Button btnRemove = new Button();
I'm creating a new solution to print a grid of my system. I think that is the best solotion, but....I need to copy some TemplateFields between two gridviews, but on the DataBind of the new grid, trows the error "the databind method like eval() only called on context control templatefield". I have Eval() instructions and I can't remove it!.Follows the exactly code:

What I want to do is to replace number with a name. So if in the Month Column it receives five "1" it changes those 5 "1" to JANUARY.
Is it possible? This is because unfortunately I can only arrange my months by number and not by their name, this because of my queries and tables format, so, I thought maybe I can tell the gridview to change the month number to their relative month name.
I have built a set of custom business objects that I have successfully bound to the GridView and DetailsView controls using the ObjectDataSource. I have been able to provide insert/update/delete functionality and all is working as expected. However, I am trying to wrap this functionality into a custom user control that allows the consumer to specify a table name and a list of column names and have it build this functionality on the fly without regard to the table structure (ie...available columns). I have been able to successfully get the GridView and DetailView to build the columns from code behind and I had all the CRUD working while using 2 panels to show/hide the GridView and DetailsView controls, but I wanted to add some AJAX ability to the control using Matt Berseth's modal popup example to make the interface slicker. The problem I am having is that the EditItemTemplate for the DetailsView control has to be specified in the code behind (because of the flexibile nature of the columns) and I can't figure out how to bind the data from code (rather than having the columns defined and bound in the markup). For all intensive purposes, I am trying to find the code behind counterpart to the following code snippet that binds the data to the textbox:

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.
