:  |  How to access a certain datagrid cell programatically without using index
Hi! This is my first post here, so be gentle.
I am trying to access a certain cell on a row in a DataGrid.
I am able to access its contens using an index value for the desired column, like this:
foreach(DataGridItem gridItem in DataGrid1.Items)
{
gridItem.Cells[4].BackColor=Color.LightBlue;
}
Where the '4' is the index of the following column:
< asp:BoundColumn DataField="lName" HeaderText="Last name">< /asp:BoundColumn>
This will work fine as long as the indexes don't change, but in case someone adds a column in the middle of the grid, this will no longer return the desired result.
Does anyone have any idea how to access the 4th cell by it's name or dataField or anything more dynamic than the index?
Thank you in advance.Started By TomppiF on Nov 8, 2005 at 12:33:55 PM

This message has been edited.I found a solution myself
I exchanged all the BoundColumns for TemplateColumns and added Labels to these. I then set the DataSource for them through the Text property, like this:
< asp:TemplateColumn HeaderText="Gender">
< ItemTemplate>
< asp:Label ID="lblGender" Runat="server" Text='< %#Convert.ToString(DataBinder.Eval(Container.DataItem,"Gender"))% >'>
< /asp:Label>
< /ItemTemplate>
< /asp:TemplateColumn>
This made it possible to programatically access the contents of a cell with the FindControl() method.
foreach(DataGridItem gridItem in DataGrid1.Items)
{
Label lblTemp = (Label)gridItem.FindControl("lblGender");
string Gender = lblTemp.Text;
lblTemp.BackColor=Color.LightBlue;
}
At least like this I don't have to use indexes. But if anyone has a different solution, with which it isn't necessary to create templatecolumns and labels, please don't hesitate to post it here.
Thank you.
