Hi there,

I have a datagrid with a the end a ButtonColumn (linkbutton). The text on the button has to change between 2 names. When the situation = a then the text on the ButtonColumn has to be different then with situation b.

How can i change the text on the buttoncolumn in de code on runtime?

I looked in the Itemcreated event, but the buttoncolumn isnt an item...

Does anyone have a helpfull advise please?

Thanks in advance.

Well if you are calling the datagrids databind() method you can do this:
   Private Sub dgItemBound(ByVal sender As Object, ByVal e As DataGridItemEventArgs) Handles [datagrid].ItemDataBound
        Dim lb As LinkButton
        If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then
            lb = CType(e.Item.Cells([Cell control is in (0 based index)]).FindControl("[linkbutton Name]"), LinkButton)
            lb.Text = "text"
        End If

    End Sub

hi, thanks for the answer, but i still need some help here.

lb = CType(e.Item.Cells([Cell control is in (0 based index)]).FindControl("[linkbutton Name]"), LinkButton)

i use c# and here is where im stuck. i cant seem to get this ctype or in c# Convert.ChangeType to work. You use Linkbutton at the end, but i dont kwno what to place here, it just nags about that i dont use the right type here.

also i want to know what/why do u use cells[] here? my column with the linkbutton is in column 8.

also i dont know what the name is of the linkbutton, i cant set a name of do u mean the text on the button perhaps?

i hope someone can help me.

thanks!

Fidelio,
  I am not sure what the C# equivelant is for that line of code, play around with it and im sure that you will figure it out. Also your post was very vague in that you didn't specifiy if you were auto generating columns, buidling the datagrid on the fly, etc.

I use the above code in conjuntion with a Datagrid whos AutoGenerateColumns value is false then I have a Datagrid <columns></columns> collection. Inside of those columns i have something like this:
    <asp:TemplateColumn>
           <ItemTemplate>
        <asp:LinkButton CommandName="Edit" Text="Edit" CausesValidation="false" runat="server" ID="Linkbutton1" />
            <asp:LinkButton CommandName="Delete" CausesValidation="False" Text="Delete" runat="server" ID="lbDelete" />
       </ItemTemplate>
       <EditItemTemplate>
        <asp:LinkButton CommandName="Cancel" CausesValidation="False" Text="Cancel" runat="server" />
        <asp:LinkButton CommandName="Update" CausesValidation="True" Text="Update" runat="server" />
      </EditItemTemplate>
    </asp:TemplateColumn>
The 2 link buttons in the EditItemTemplate are hidden until the datagrid 'Edit' Command is called the first 2 link buttons appear as the first cell in every row and are visible when the Databind() method is called on the datagrid and if you look, i have named that link button so my code would look like this:
        lb = CType(e.Item.Cells(0).FindControl("lbDelete"), LinkButton)

As far as your question about why do I use cells, that is how you manipulate controls or text inside of a datagrid, you have to select the cell and then the control you want to work with (or the text in the cell if there is no control). As far as the why for this? Ask Microsoft. Hope this helps.

hello,

thanks for your very helpfull answers. sorry for that i wasnt very accurate in my problem description.

i already got the solution by using a template column in the datagrid. then i could use the findcontrol() function.

thanks for the help and efforts.
