radgrid in side tabs

[Sudhakar]

Hi Team,

I have a radgrid with some rows in it .When i expand the each row there are three tabs inside it.
When i click on the first tab need to display the grid(grid name:compartmentgrid) under this tab.In this grid i have 8 coloumns and some columns have no data in it.
I need to find out the which column has no data and highlight that column with yellow color.
I am writing the code in the itemdatabound event for this grid.
How to find which column has null value because it is inside another grid and also this grid is displayed once you click on the tab.

Regards,
Sudhakar.

Hello Sudhakar,

In order to achieve the described behavior you could handle the ItemDataBound event of the nested RadGrid. In the handler you could iterate through the values for the cells every row. If there is no text in the cell you could set its background color. Check the following code snippet for illustration.

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        RadGrid grid = sender as RadGrid;

        GridDataItem dataItem = e.Item as GridDataItem;

        foreach (GridColumn column in grid.Columns)
        {
            if (column is GridEditableColumn && dataItem[column].Text == " ")
            {
                dataItem[column].BackColor = System.Drawing.Color.Yellow;
            }
        }
    }
}
