Make a cell read only based on its value (from db)

Hello Naresh,

I suppose you mean to disable a control in Edit mode depending on the specific value.

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    Hashtable table = new Hashtable();
    GridEditFormItem item = e.Item as GridEditFormItem; //GridDataItem for InPlace
    if (item != null && item.IsInEditMode)
    {
        item.ExtractValues(table);
        string value = table["yourColumnName"].ToString();
        if (value == "Beverages")
            (item["yourColumnName"].Controls[0] as TextBox).ReadOnly = true;
    }
}

Let me know if I missed something.

hello,
Dim item As GridEditFormItem = TryCast(e.Item, GridEditFormItem)

e.item is GridDataItem
item is nothing

Hello Naresh,

If the EditMode property is set to InPlace the item will be GridDataItem.

<MasterTableView EditMode="InPlace"...

Otherwise if EditForms mode is used the item will be GridEditFormItem

<MasterTableView EditMode="EditForms"...

Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As GridItemEventArgs)
    Dim table As New Hashtable()
    Dim item As GridEditFormItem = TryCast(e.Item, GridEditFormItem)
    'GridDataItem for InPlace
    If item <> Nothing AndAlso item.IsInEditMode Then
        item.ExtractValues(table)
        Dim value As String = table("yourColumnName").ToString()
        If value = "Beverages" Then
            (TryCast(item("yourColumnName").Controls(0), TextBox)).[ReadOnly] = True
        End If
    End If
End Sub
