Hello All,
I am trying to use the following RowCreated Event Handler to make the
BackColor of a cell different if it has a particular value.
protected void GridView1_RowCr eated(object sender,
GridViewRowEven tArgs e)
{
if (e.Row.RowType == DataControlRowT ype.DataRow)
{
object cellValue = DataBinder.Eval (e.Row.DataItem ,
"Primary Diagnosis");
if(cellValue != null)
{
if (cellValue.Equa ls("Unknown or Service Recipient
Declined"))
{
e.Row.Cells[1].BackColor = Color.Yellow;
}
}
}
}
The page works as expected the first time it is loaded. But if it is a
PostBack cellValue is null, so the code to color the cells BackColor
does not run. If I take out condition "if(cellVal ue != null) I get an
error message. How can I use the RowCreated Event handler to control
the BackColor of cells even when it is a PostBack.
Help is always appreciated. Thanks,
Paul 2 9051
Paul,
Two things:
1. Use RowDataBound event instead of RowCreated.
2. There is no need to call DataBinder.Eval . You can use e.Row.DataItem with
typecasting. If your datasource is a datatable, you can write something like
object cellValue = (DataRowView)e. Row.DataItem["Primary Diagnosis"];

I would be very grateful for any help on this question. I have an
application in asp.net 2.0 where I dynamically create a datatable and then
bind that to a gridview. Unfortunately, the date column always shows the
date and time while I just want the short date. I have tried applying a
format string {0:d} but to no avail. I saw a lot of posts regarding the
htmlencode property but I do not know how to turn that off for a...

Hi there experts,
I have a gridview with a couple textboxes and a dropdownlist. I'm

I'm doing this in the rowdatabound event. My problem is that my code

when I press "edit", my gridview goes to edit mode, my textboxes and
dropdownlist populate. Further, my dropdownlist has the "Select" I

I have a gridview with a template column containing an imagebutton to delete
the row.
Under some condition I don't want the row to be deleted, so would like to
remove the button.
In the RowDataBound event, I can find the button, but can't seem to remove
it.
The code below does not throw any exception, but the button is not removed.

Hi,
The funniest part of the problem described here is that I am not new to
ASP.NET, but honestly here I have no idea about what's going on.
I have a GridView with a data source that just returns 1 row of only 1
column.
The GridView has only one field, a TemplateField.
In GridView.RowCreated, I create a TextBox under a PlaceHolder statically
