GridBoundColumn ReadOnly="true"

[Syed M Ali Shah]

Hi,

I am having problem in accessing value from a column with ReadOnly="True". Actually i don't want a column (e.g. PriceID) to be displayed in Insert/Edit Form, but i need its value to update the records in database. Currently if I set the readonly="false" it gets the value , but when its "true" then value in PriceID remains NULL.

Please help me in writing code , so that I can access value from a Readonly="true" column, and it should not be visible in grid and in editmode.

Thanks

Cheers, ALi

Hi Syed,

One suggestion would be setting the DataKeyNames property of RadGrid and gettuing the value using " GetDataKeyValue " method as shown below.

ASPX:

 . . .
<Columns>
    <telerik:GridBoundColumn  ReadOnly="true" DataField="CustomerID" HeaderText="CustomerID" SortExpression="CustomerID"
        UniqueName="CustomerID">
    </telerik:GridBoundColumn>
     . . .
</Columns>
 . . .

C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridEditableItem && e.Item.IsInEditMode)
    {
        GridEditableItem item = (GridEditableItem)e.Item;
        Response.Write(item.GetDataKeyValue("CustomerID"));
    }
}
