Disable the cells based on the value in other column.

[Subh]

I have three columns "Column1","Column2","Column3". Based on the value in "Column1" the "Column2" and "Column3" should be disabled or enabled. How can this be implemeneted?

Thanks in advance.

Hey Subh,

You can prevent the user from editing a cell using the CellBeginEdit event. Here is a quick example:

        private void radGridView1_CellBeginEdit(object sender, Telerik.WinControls.UI.GridViewCellCancelEventArgs e)
        {
            if (radGridView1.Columns[e.ColumnIndex].FieldAlias == "ItemID")
            {
                if (((int)radGridView1.Rows[e.RowIndex].Cells[0].Value) > 10)
                    e.Cancel = true;
            }
        }

Hi Subh,

I suppose that you want to disable the editing of specific cell. If this is the case, you can handle CellBeginEdit event. Please consider the sample below:

void radGridView1_CellBeginEdit(object sender, GridViewCellCancelEventArgs e)
{
    GridViewDataColumn column = (GridViewDataColumn)this.radGridView1.CurrentColumn;
    if ((column.UniqueName == "Column2" || column.UniqueName == "Column3"))
    {
        if ((int)this.radGridView1.CurrentRow.Cells["Column1"].Value < 10)
        {
            e.Cancel = true;
        }
    }
}

Additionally you can change the cell appearance when handling CellFormatting event. Take a look at the following KB article for more information.

If you have any further questions, don't hesitate to ask.
