I am working in sharepoint moss site.I have created one web part. In my web part i am using Rad Ajax Panel with some ASP.net controls. I am using <asp:panel> and <asp:LinkButton> and rad rotator , inside Rad Ajax Panel. My problem is that ,when i click on any link button first time , the PAGE is getting full post back.After that it behaves as expected.
Following is my code:-
<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">
<table width="652" border="0" cellspacing="0" cellpadding="0">
<tr>
<td align="left" valign="top" scope="col"><table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td align="left" valign="top" scope="col" class="prismbannerTopleft"></td>
<td align="left" valign="top" scope="col" class="prism_bannerTopMiddle"></td>
<td align="left" valign="top" scope="col" class="prismbannerTopRight"></td>
</tr>
<tr>
<td align="left" valign="top" scope="col" class="prism_bannerMiddleleft"> </td>
<td align="left" valign="top" scope="col" >
<telerik:RadRotator ID="rrMonths" runat="server" AutoPostBack="false"
OnItemDataBound="rrMonths_ItemDataBound" ScrollDuration="2000" >
<ItemTemplate>
<asp:Image AlternateText="IMAGE" ID="Image2" runat="server" ImageUrl='<%#DataBinder.Eval(Container.DataItem, "Image") %>'/>
<asp:HiddenField ID ="hdnid" runat ="server" Value='<%# DataBinder.Eval(Container.DataItem, "Id") %>' />
</ItemTemplate>
</telerik:RadRotator>
</td>
<td align="left" valign="top" scope="col" class="prism_bannerMiddleRight"> </td>
</tr>
<tr>
<td align="left" valign="top" scope="col" class="prism_bannerBottomleft"></td>
<td align="left" valign="middle" scope="col" class="prismbannerBottomtext">
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td width="72%" height="30" align="right" valign="middle" scope="col">
<asp:Panel runat="server" ID="PanelNumber" Width="200" HorizontalAlign="Right">
<asp:LinkButton ID="lnkdemo1" runat="server">1</asp:LinkButton> <br/>
<asp:LinkButton ID="lnkdemo2" runat="server">2</asp:LinkButton><br/>
<asp:LinkButton ID="lnkdemo3" runat="server">3</asp:LinkButton><br/>
<asp:LinkButton ID="lnkdemo4" runat="server">4</asp:LinkButton><br/>
<asp:LinkButton ID="lnkdemo5" runat="server">5</asp:LinkButton><br/>
</asp:Panel>
</td>
</tr>
</table>
</td>
<td align="left" valign="top" scope="col" class="prism_bannerBottomRight"></td>
</tr>
</table></td>
</tr>
</table>
</telerik:RadAjaxPanel>

Could you please specify how the problematic web part is loaded? Is it declaratively added on the page or you are loading it dynamically?

Following code i am using to load my webpart , In my web part inside .cs file ,using following function.
protected
override void CreateChildControls()
{
try
{
UC_Rotator UCRotator = (UC_Rotator)this.Page.LoadControl(@"~/_CONTROLTEMPLATES/Smithsonian Controls/UC_Rotator.ascx");
UCRotator.ID =
"UCRotator";
UCRotator.Rheight =
this.Rheight;
UCRotator.Rwidth =
this.Rwidth;
UCRotator.Itemheight =
this.Itemheight;
UCRotator.Itemwidth =
this.Itemwidth;
UCRotator.Home =
this.Home;
this.Controls.Add(UCRotator);
ViewState[
"demo"] = "true";
//base.CreateChildControls();
}
catch (Exception oEx)
{
HttpContext.Current.Response.Write("Create child control: " + oEx.Message);
}
}
In this case I suggest that you ajaxify the problematic web part using RadAjaxManager instead of RadAjaxPanel. For that purpose, you need to add the RadAjaxManager in the OnInit event handler as shown below. Then you can wrap the web part content into an ASP:Panel and ajaxify it by adding the ajax settings dynamically on Load or PreRender event.
RadAjaxManager ajaxManager = RadAjaxManager.GetCurrent(this.Page); if (ajaxManager == null) { ajaxManager = new RadAjaxManager(); ajaxManager.ID = "RadAjaxManager1"; this.Page.Form.Controls.Add(ajaxManager); this.Page.Items.Add(typeof(RadAjaxManager), ajaxManager); }Give it a try and let me know if it makes any difference.

Thank u so much !! this helped me a lot. My problem has solved I added Rad Ajax panel dynamically in my program under OnLoad event. Following code worked for me.
protected override void OnLoad(EventArgs e)
{
try
{
base.OnLoad(e);
_updatePanel = new RadAjaxPanel();
_updatePanel.ID = "UpdatePanel1";
this.Controls.Add(_updatePanel);
Panel pnlsearch = (Panel)UCRotator.FindControl("demo");
_updatePanel.Controls.Add(pnlsearch);
}
catch (Exception ex)
{
HttpContext.Current.Response.Write("Error :" + ex.Message);
}
}
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
if (ScriptManager.GetCurrent(this.Page) == null)
{
ScriptManager managers = new RadScriptManager();
this.Page.Form.Controls.AddAt(0, managers);
}
}
private void EnsureUpdatePanelFixups()
{
if (this.Page.Form != null)
{
String fixupScript = @"_spBodyOnLoadFunctionNames.push(""_initFormActionAjax"");
function _initFormActionAjax()
{
if (_spEscapedFormAction == document.forms[0].action)
{
document.forms[0]._initialAction =
document.forms[0].action;
}
}
var RestoreToOriginalFormActionCore =
RestoreToOriginalFormAction;
RestoreToOriginalFormAction = function()
{
if (_spOriginalFormAction != null)
{
RestoreToOriginalFormActionCore();
document.forms[0]._initialAction =
document.forms[0].action;
}
}";
ScriptManager.RegisterStartupScript(this, typeof(Rotator), "UpdatePanelFixup", fixupScript, true);
}
}
protected override void CreateChildControls()
{
try
{
if (BrowserDesignMode)
{
//nothing
}
else
{
base.CreateChildControls();
this.EnsureUpdatePanelFixups();
UCRotator = (UC_Rotator)this.Page.LoadControl(@"~/_CONTROLTEMPLATES/Smithsonian Controls/UC_Rotator.ascx");
UCRotator.ID = "UCRotator";
UCRotator.Rheight = this.Rheight;
UCRotator.Rwidth = this.Rwidth;
UCRotator.Itemheight = this.Itemheight;
UCRotator.Itemwidth = this.Itemwidth;
UCRotator.Home = this.Home;
this.Controls.Add(UCRotator);
ViewState["demo"] = "true";
//base.CreateChildControls();
}
}
catch (Exception oEx)
{
throw oEx;
}
finally
{
}
}
