Hi Telerik team,

I have strange problem.

First time page get's loaded with no problem but when I clicked on any page number for paging I got following error:

"Microsoft JScript runtime error: Sys.ArgumentException: Value must not be null for Controls and Behaviors. Parameter name: element"

For paging I am using SetGridData(); method.

Also want to let you know that after commenting following code everything works fine.

//Get the last PAgeindex.
int getPageindex = 0;
getPageindex = mybible.Count / rgTemplates.PageSize;

if (getPageindex == Convert.ToInt16(HttpContext.Current.Session["CPI"]))
{
RadSplitter1.CssClass = "AutoHeight1";
Radpane2.CssClass = "AutoHeight1";

}

this.rgTemplates.DataSource = mybible;
Session.Remove("CPI");
}
catch (Exception ex)

}

Please help me.

Hi Shirish,

In order to fix this issue you have to either set your ajax settings to update only the grid or you have to set your setting to update the whole RadSplitter. Check out the following code snippet.

First approach:

<

telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<ClientEvents OnRequestStart="onRequestStart" />

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="rgTemplates">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="rgTemplates" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="btnSearch">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="rgTemplates" />

<telerik:AjaxUpdatedControl ControlID="btnSearch" />

<telerik:AjaxUpdatedControl ControlID="RadSplitter1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

Second approach:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<ClientEvents OnRequestStart="onRequestStart" />

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadSplitter1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadSplitter1" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="btnSearch">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="rgTemplates" />

<telerik:AjaxUpdatedControl ControlID="btnSearch" />

<telerik:AjaxUpdatedControl ControlID="RadSplitter1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager

I hope this helps.
