I'm trying to determine weather to show or hide the checkbox in a GridCheckBoxColumn inside the grid's ItemDataBound event. I thought this would be a simple task.
Inside my ItemDataBound method:
if (e.Item is GridDataItem)
{
GridDataItem dataItem = e.Item as GridDataItem;
if (dataItem["ItemTypeName"].Text.Equals("Sponsorship"))
{
CheckBox cb = (CheckBox)dataItem["column"].Controls[0];
//cb.Enabled = false;
cb.Visible = false;
//cb.Checked = true;
lbCancelEntireOrder.Visible = false;
}
}
the lbCancelEntireOrder.Visible line works - so I know the problem is not in the ItemDataBound itself. Am I getting the CheckBox out of the column properly?
Thanks

This code is pretty close to what I had - but I did copy it all and paste it into my page with the same results. The label's visibility is properly set to false, but the checkbox just will not go away.

Hi Dj,
Can you check whether you have set the correct ColumnUniqueName for the CheckBox Column? Sending your aspx code will be more good.

Ok, I removed everything except the UniqueName from the column:
And I've modified my aspx.cs page a little bit:
The lines that hides lbCancelEntireOrder works - while the line that hides chkbx does nothing.
What am I doing wrong here, any idea? Thanks.
<radG:GridCheckBoxColumn UniqueName="cbCol"> |
</radG:GridCheckBoxColumn> |
And I've modified my aspx.cs page a little bit:
protected void rdgOrderItems_OnItemDataBind(object sender, Telerik.WebControls.GridItemEventArgs e) |
{ |
if (e.Item is GridDataItem) |
{ |
GridDataItem item = (GridDataItem)e.Item; |
CheckBox chkbx = (CheckBox)item["cbCol"].Controls[0]; |
string strtxt = item["ItemTypeName"].Text.ToString(); |
if (strtxt == "Sponsorship") |
{ |
chkbx.Visible = false; |
lbCancelEntireOrder.Visible = false; |
} |
} |

Hi DJ,
Could try the same code in the ItemCreated event handler? Try it out and let me know if this helped.
Thanks,

I put the code into an OnItemCreated method and get the same results.
I also tried to loop through all rows in the PreRender of the grid, but that didn't work either.
I'm starting to get really frustrated with this. Telerik has typically been good to me, but not the GridCheckBoxColumn.

Thanks for the example. That is pretty much what I was trying to accomplish, but 2 minor differences.
1. My form was put into edit mode so the checkboxes were enabled.
2. My column didn't have a DataType.
I've just removed the whole column instead of tyring to hide individual checkboxes - that is going to work just fine for me.
Thanks
