Radgrid postback issue

[Dayana Maliyakal]

Hello Telerik Team,
    I have a RadGrid with RadComboBox as GridTemplateColumn.Its property autopostback is true.When working onselectedindexchanged property of RadComboBox, how can we avoid its postback ?

The code is like as follows.

<

 

telerik:GridTemplateColumn HeaderText="QTY" SortExpression="quantity" >

 

 

<ItemTemplate>

 

 

<label><%#Eval("quantity")%></label></ItemTemplate>

 

 

<EditItemTemplate>

 

 

<telerik:RadNumericTextBox ID="rntUQuantity" runat="server" NumberFormat-KeepNotRoundedValue="true"

 

 

Width="65%" Value='<%#Convert.ToDouble(Eval("UQuantity")) %>'>

 

 

<NumberFormat GroupSeparator="," DecimalDigits="3"></NumberFormat>

 

 

</telerik:RadNumericTextBox>

 

 

<telerik:RadComboBox ID="rUM" DataTextField="UM" DataValueField="UMID"

 

 

runat="server" AutoPostBack="true"

 

 

Width="35%" DataSource='<%#UOM%>'

 

 

onselectedindexchanged="rUM_SelectedIndexChanged">

 

 

</telerik:RadComboBox>

 

 

<asp:HiddenField ID="hdUOM" Value='<%#Eval("UMID")%>' runat="server" />

 

 

</EditItemTemplate>

 

 

<HeaderStyle Width="13%" Wrap="false" HorizontalAlign="Right" />

 

 

<ItemStyle Width="13%" Wrap="false" HorizontalAlign="Right" />

 

 

</telerik:GridTemplateColumn>

Hello Dayana,

Note that the SelectedIndexChanged event does not fire unless the AutoPostBack property is True. Therefore I would suggest that you load your comboboxes on demand instead of using the SelectedIndexChanged event. You can find more information here.
