Cant get a column value in ItemDataBound

[Mike]

Hi,

I know this is probably a very simple scenario but I cannot work it out. I need to get the "Username" value from a GridTemplateColumn and place it into the ItemDataBound event in the code behind, here is the column:

<telerik:GridTemplateColumn DataField="Username"

HeaderText="Username"

UniqueName="Username"

SortExpression="Username">

<ItemTemplate>

<asp:Label ID="lblUsername" runat="server" Text='<%# Eval("Username") %>' />

</ItemTemplate>

</telerik:GridTemplateColumn>

And here is the code behind:

    protected void MembersGrid_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if ((e.Item is GridDataItem))
        {
            GridDataItem dataItem = (GridDataItem)e.Item;
            string username = dataItem["Username"].Text;

            ImageButton btnEditUser = (ImageButton)e.Item.FindControl("EditUserImgBtn");
            btnEditUser.Attributes["href"] = "#";
            btnEditUser.Attributes["onclick"] = String.Format("return ShowEditUser('{0}', '{1}');", username, e.Item.ItemIndex);
    }
    }

I need to get the value of the GridTemplateColumn ("Username") into the ShowEditUser('{0}', '{1}');", username, e.Item.ItemIndex), can someone please offer some advice this would be much appreciated.

Do I need to use a GridBoundColumn instead of the above? I don't think that would make any difference though.

Thank you in advance for help :)

Hi Grant,

Could you please try the following code snippet:

protected void MembersGrid_ItemDataBound(object sender, GridItemEventArgs e)
{
    if ((e.Item is GridDataItem))
    {
        GridDataItem dataItem = (GridDataItem)e.Item;
        Label usernameLabel = dataItem["Username"].FindControl("lblUsername") as Label;
        string username = usernameLabel.Text;

        ImageButton btnEditUser = (ImageButton)e.Item.FindControl("EditUserImgBtn");
        btnEditUser.Attributes["href"] = "#";
        btnEditUser.Attributes["onclick"] = String.Format("return ShowEditUser('{0}', '{1}');", username, e.Item.ItemIndex);
     }
}

For more information on how to access cells and rows please check out the following online documentation article:

I hope this helps.

Hello Grant,

One method that you can try is accessing the Label control and get the value by accessing the Text property.

C#:

    protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if ((e.Item is GridDataItem))
        {
            GridDataItem dataItem = (GridDataItem)e.Item;
            Label lbl = (Label)dataItem.FindControl("lblUsername");
            string username = lbl.Text;
        }
    }

Thanks Radoslav and Shinu

It was 2:30am after an 18 hour day and now I feel so stupid because the answer is quite obvious. I have been using telerik controls for quite a while now and I must have been suffering from a brain lapse or something sheeesh, sorry to waste your time guys but I guess this may help someone new to using the controls.

Cheers ;)
