Hi
Maria Ilieva,
You can see the following code to simulate the behavior. There is no error in javascript.
ASPX page:
<telerik:RadScriptManager ID="RadScriptManager1" runat="server" OnAsyncPostBackError="RadScriptManager_AsyncPostBackError">
<Scripts>
<%--Needed for JavaScript IntelliSense in VS2010--%>
<%--For VS2008 replace RadScriptManager with ScriptManager--%>
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
</Scripts>
</telerik:RadScriptManager>
<telerik:RadAjaxManager ID="RadAjaxManager" runat="server">
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="RadGridFunction">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="RadGridFunction" LoadingPanelID="RadAjaxLoadingPanelFunction" />
</UpdatedControls>
</telerik:AjaxSetting>
</AjaxSettings>
</telerik:RadAjaxManager>
<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanelFunction" runat="server" />
<telerik:RadGrid runat="server" ID="RadGridFunction" AutoGenerateColumns="true" CellSpacing="0"
Width="850px" GridLines="None" OnUpdateCommand="RadGridFunction_UpdateCommand" ShowStatusBar="true" AllowPaging="true" >
<MasterTableView DataKeyNames="ID">
<Columns>
<telerik:GridEditCommandColumn>
</telerik:GridEditCommandColumn>
</Columns>
</MasterTableView>
<ClientSettings EnableRowHoverStyle="true">
<Selecting AllowRowSelect="true" />
</ClientSettings>
<ValidationSettings CommandsToValidate="PerformInsert,Update" />
<PagerStyle AlwaysVisible="true" />
</telerik:RadGrid>
</telerik:RadAjaxLoadingPanel>
<script>
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(function (sender, args) {
var error = args.get_error();
if (error != undefined && error.httpStatusCode == '500') {
args.set_errorHandled(true);
}
});
</script>
CS code:
protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable();
dt.Columns.Add("ID");
dt.Columns.Add("Name");
for (int i = 0; i < 10; i++)
{
DataRow dr = dt.NewRow();
dr["ID"] = i.ToString();
dr["Name"] = "Name:" + i.ToString();
dt.Rows.Add(dr);
}
this.RadGridFunction.DataSource = dt;
this.RadGridFunction.DataBind();
}
protected void RadGridFunction_UpdateCommand(object sender, GridCommandEventArgs e)
{
throw new Exception();
}
protected void RadScriptManager_AsyncPostBackError(object sender, AsyncPostBackErrorEventArgs e)
{
RadScriptManager1.AsyncPostBackErrorMessage = e.Exception.Message;
}
