Problem with the grid when click on Add new record button

[Trinh Nguyen]

I have the Telerik grid with custom rows to appear and disappear using:

    for (int i = 0; i < RadGridMain.MasterTableView.Items.Count; i++)

        {

            if (masterCL.Contains(int.Parse(RadGridMain.MasterTableView.DataKeyValues[i]["MasterChecklistID"].ToString())))

            {

                RadGridMain.MasterTableView.Items[i].Visible = false;

                RadGridMain.MasterTableView.Items[i].Enabled = false;

                RadGridMain0.MasterTableView.Items[i].Visible = true;

                flag = false;

            }

            else

            {

                RadGridMain.MasterTableView.Items[i].Visible = true;

                RadGridMain0.MasterTableView.Items[i].Visible = false;

            }

        }

Some of the columns in RadGridMain will invisble based on the method above. However, when I click on the Add new record to add new item. The invisible columns are visible again... how can I make it still invisible when clicking on Add new record button?

Thanks

Hi,

You could try your code in PreRender event of the RadGrid after checking for the condition as shown below. PreRender is fired when the server control is about to render to its containing Page object. I hope this would help.

C#:

protected void RadGrid1_PreRender(object sender, EventArgs e)
{
    if (condition) // Check for the condition here
    {
        for (int i = 0; i < RadGridMain.MasterTableView.Items.Count; i++)
        {
            if (masterCL.Contains(int.Parse(RadGridMain.MasterTableView.DataKeyValues[i]["MasterChecklistID"].ToString())))
            {
                RadGridMain.MasterTableView.Items[i].Visible = false;
                RadGridMain.MasterTableView.Items[i].Enabled = false;
                RadGridMain0.MasterTableView.Items[i].Visible = true;
                flag = false;
            }
            else
            {
                RadGridMain.MasterTableView.Items[i].Visible = true;
                RadGridMain0.MasterTableView.Items[i].Visible = false;
            }
        }
    }
}
