Template columns in datagrid

Not quite sure I understand, but after you add a row, if you bind the grid again, the new row would show up and your ItemDatabound would catch it just like it would an "old" row

On the add button column, I add this row to the datatable and bind the datagrid. However the ItemDatabound event was not trigerred.

Than ks

can you post some code?
Every time a grid is bound, the ItemDatabound event **is** triggered. period.

Some of the Design:
<asp:DataGrid id="dgDynamicFields" Runat="server" Width="600px"  DataKeyField="FieldId"
                              CssClass="griddata" AutoGenerateColumns="False">
<asp:BoundColumn DataField="IsVisible" HeaderText="IsVisible" visible="false"></asp:BoundColumn>
<asp:TemplateColumn HeaderText="Visible">
<ItemTemplate>
<asp:CheckBox ID="chkVisible" Runat="server" Width="40px" />                  
</ItemTemplate>
</asp:TemplateColumn>


On addrow button click:

//first add the row to the datatable then I do the following:
DataView dvDynamicFields = new DataView(dtDynamic);
dgDynamicFields.DataSource = dvDynamicFields;
dgDynamicFields.DataBind();

The following is the itemdatabound event:
private void dgDynamicFields_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
        {
            if (((e.Item.ItemType == ListItemType.Item)
                       || (e.Item.ItemType == ListItemType.AlternatingItem)))
            {

                CheckBox chkVisibleField = e.Item.Cells[8].FindControl("chkVisible") as CheckBox;
                chkVisibleField.Checked = Convert.ToBoolean(e.Item.Cells[8].Text);
               
            }
        }

Please let me know if you need me to post any other sections. Anyt help will greatly be appreciated.Thanks a lot.

from what I can tell, it looks ok....
are you sure the new data is getting added to dtDynamic?

yes. the data is added to the dtdynamic becuase I have other bound columns that show up. all the rows, right from the row 1 after the addrow button click loose the values that were assigned in the itemdatabound event.

first of all DataGrid doesnt have any facility directly to add dynamic row
so its depends how u ADD new row in DataGrid

jus clarify me i can give you solutions. as i had done lots of time to add dynamically data with DataGrid and GridView

thanx

YEs, I am trying to assign the value form the previous bound column. Sorry it was a typo as you said my code does read the following in my application:
chkVisibleField.Checked = Convert.ToBoolean(e.Item.Cells[7].Text);
However all this work perfectly during the initial page rendering. This column and a couple of other columns I assign value during the ITemdatabound event get assigned correct values. However after I add row, these template columns are not assigned the correct values. When I put a break point in the Item Databound event control never goes to this section after the Addrow button click although I call Datagrid.databind().

Thanks

Ok the issue was that I had wired the Item Databound event inside the if(!Ispostback) section. Now I moved it out and the event is trigerred and the reqauired values are assigned ot all the columns;
 dgDynamicFields.ItemDataBound += new DataGridItemEventHandler(dgDynamicFields_ItemDataBound);
            if (!IsPostBack)
{
}

However, you had spent a lot of time trying to help me and giving me suggestons. Probaly if I had included this code you would have spot the issue. So I am going to go ahead and assign the points to you.

Thank you for your help and time.

Forced accept.
