Edit/Insert mode on gridNumricColumn

[Cecilie Nordbø]

Hi.
Is it possible to distinguish between edit and insert mode for a gridNumricColumn when not use a formTemplate?
I have read the documentation Distinguish edit/insert mode on ItemCreated/ItemDataBound but i still have problem to get it to work.
I want the gridNumricColumn (CardNumber) to be readonly=false when insertmode and readonly=true otherwise. The problem is that the field CardNumber is not visible when insertmode withe the following code:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)

{         

if (e.Item is GridDataInsertItem && e.Item.IsInEditMode)

    {
  var column = (GridNumericColumn)e.Item.OwnerTableView.GetColumnSafe("CardNumberColumn"); 

  if (e.Item.OwnerTableView.IsItemInserted)

       column.ReadOnly = false;

               else

       column.ReadOnly = true;

 }

}

<telerik:RadGrid ID="RadGrid1" runat="server"AllowAutomaticInserts="True"   AllowAutomaticUpdates="True" DataSourceID="LinqDataSource1" ondatabound="RadGrid1_DataBound" onitemcommand="RadGrid1_ItemCommand"           onitemdatabound="RadGrid1_ItemDataBound" onitemcreated="RadGrid1_ItemCreated">
<MasterTableView AutoGenerateColumns="FalseDataKeyNames="CardNumber,ProductNumber,MediaType"
         DataSourceID="LinqDataSource1" EditMode="InPlace" >
<Columns>
       <telerik:GridNumericColumn DataField="CardNumber" DataType="System.Int32" HeaderText="Kortnr." ReadOnly="true" SortExpression="CardNumber" UniqueName="CardNumberColumn" >
       </telerik:GridNumericColumn>
       <telerik:GridBoundColumn DataField="CardName" HeaderText="Kortnavn" SortExpression="CardName" UniqueName="CardName" >
       </telerik:GridBoundColumn>
       <telerik:GridEditCommandColumn CancelText="Avbryt" EditText="Endre" InsertText="Sett inn" UpdateText="Oppdater"></telerik:GridEditCommandColumn>
       </Columns>
   </MasterTableView>
   </telerik:RadGrid>

Have tried both with ItemCreated and ItemDataBound methode.

Hello,

You can achieve this by accessing the RadNumericTextBox control and then set its ReadOnly property accordingly. Check out the following codes snippet.

ASPX:

<telerik:GridNumericColumn DataField="CardNumber" DataType="System.Int32" HeaderText="Kortnr." SortExpression="CardNumber" UniqueName="CardNumberColumn" >
</telerik:GridNumericColumn>

C#:

if (e.Item.OwnerTableView.IsItemInserted && e.Item is GridDataInsertItem)

       //item is about to be inserted  

       {

           GridDataInsertItem insertItem = (GridDataInsertItem)e.Item;

           RadNumericTextBox txtBox = (RadNumericTextBox)insertItem["CardNumberColumn"].Controls[0];

           txtBox.ReadOnly = false;

       }

       if (!(e.Item is GridDataInsertItem) && e.Item.IsInEditMode)

       //item is about to be edit

       {

           GridEditableItem editItem = (GridEditableItem)e.Item;

           RadNumericTextBox txtBox = (RadNumericTextBox)editItem["CardNumberColumn"].Controls[0];

           txtBox.ReadOnly = true;

       }

Thanks,
Princy.
