Autopostback and RadNumericTextBox

[alphonse joseph]

Hi,
    I am using RadNumericTextBox inside the <edititemtemplate> tag of a RadGrid. I have set autopostback property of RadNumericTextBox to false.  Still when I press Enter key postback happens.  Given below is my code:

 <telerik:RadGrid ID="grdTrans" GridLines="None"  AutoGenerateColumns="false" Height="500px"
           AutoGenerateEditColumn="false" AutoGenerateDeleteColumn="false"
           runat="server"  OnCancelCommand="grdTrans_CancelCommand"
           AllowPaging="false" AllowSorting="false"
           OnDeleteCommand="grdTrans_DeleteCommand"  OnUpdateCommand="grdTrans_UpdateCommand"
           onneeddatasource="grdTrans_NeedDataSource"
           oninsertcommand="grdTrans_InsertCommand"
           onitemdatabound="grdTrans_ItemDataBound"
           oneditcommand="grdTrans_EditCommand" >
            <MasterTableView Name="master"  EditMode="InPlace" GridLines="None" DataKeyNames="accid" CommandItemDisplay="Bottom" >
                <Columns>
                  <telerik:GridEditCommandColumn>
                   </telerik:GridEditCommandColumn>

<telerik:GridTemplateColumn  HeaderText="Debit" UniqueName="debit" DataType="System.Decimal" ItemStyle-Width="100px" ItemStyle-HorizontalAlign="Right" >
                        <ItemTemplate>
                                       <asp:Label ID="lblDbAmt" Text= '<%# Eval("dbamt") %>' CssClass="labels"   runat="server"> </asp:Label>
                        </ItemTemplate>
           
                       <EditItemTemplate>
                              <telerik:RadNumericTextBox ID="txtDbAmt" Text  = '<%# bind("dbamt") %>' MinValue="0" MaxValue="99999999.99" MaxLength="11" DataType="System.Decimal" Culture="en-GB"  AutoPostBack="false" ClientEvents-OnKeyPress="KeyPressed" EnabledStyle-HorizontalAlign="Right" runat="server">                   
                            <NumberFormat AllowRounding="false" DecimalDigits="2" DecimalSeparator="." GroupSeparator="," GroupSizes="3"   />
                             </telerik:RadNumericTextBox>                       
                       </EditItemTemplate>
 </telerik:GridTemplateColumn>   

I had to use the following javascript function to avoid postback:
 function KeyPressed(ctrl, e) {
             if (e.get_domEvent().rawEvent.keyCode == 13) { //enter  
                 //special handling (focus other control and so on) here  
                 e.get_domEvent().preventDefault();
                 e.get_domEvent().stopPropagation();
             }

Is there any workaround other than using the above javascript.

Hi alphonse,

The behavior you are getting is caused by the ASP.NET form itself, where on Enter, the form is posted from the first submit button in it. For more info:

Enter key in ASP.NET

To prevent the Enter key, the approach you have taken is the right one for RadGrid.

All the best,
