Hi kotu k,

You can easily achieve that by subscribing to ValueChanged event and CellFormatting event. You can use the following code snippet:

private void radGridView2_ValueChanged(object sender, EventArgs e)
{
    RadComboBoxEditor comboBoxEditor = sender as RadComboBoxEditor;

    if (comboBoxEditor != null)
    {
        this.radGridView2.CurrentRow.InvalidateRow();
    }
}

private void radGridView2_CellFormatting(object sender, CellFormattingEventArgs e)
{
    GridCellElement cellElement = e.CellElement;

    if (!(cellElement.RowInfo is GridViewDataRowInfo))
    {
        return;
    }


    if (cellElement.ColumnInfo.Name == "Name" ||
        cellElement.ColumnInfo.Name == "HireDate")
    {
        RadComboBoxEditor comboBoxEditor = this.radGridView2.ActiveEditor as RadComboBoxEditor;

        object value = null;

        if (comboBoxEditor != null)
        {
            value = comboBoxEditor.Value;
        }
        else
        {
            value = e.CellElement.RowInfo.Cells["ComboBox"].Value;
        }

        // Your condition should be here
        if (Convert.ToString(value).Contains("2"))
        {
            e.CellElement.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
        }
        else
        {
            e.CellElement.ResetValue(LightVisualElement.VisibilityProperty, Telerik.WinControls.ValueResetFlags.Local);
        }

    }
    else
    {
        e.CellElement.ResetValue(LightVisualElement.VisibilityProperty, Telerik.WinControls.ValueResetFlags.Local);
    }
}

In ValueChanged event we invoke InvalidateRow method, which force CellFormatting event to be processed. You can read more about it in this documentation article.

Notice that the supplied code snippet works in the latest version Q2 2010 (v2010.2.10.713).

All the best,

Hi kotu k,

Could you give me more information about your scenario? What exactly are your requirements? The GridCellElement instances are virtualized and reused each time when you scroll down the grid. Hence, you cannot directly bind another components to the cell element. Probably, you want to do it for its data source. RadGridView does not restricts the possibility to achieve that.
