Poblem on Dynamic create RadTabStrip With Ajax

[Peter]

 Hi All,

I have an issue with RadTabStrip control when I create this control at runtime by using ajax. I alsway have the js error:  "

Microsoft JScript runtime error: Sys.ArgumentUndefinedException: Value cannot be undefined.

Parameter name: type"

Could you tell me how to solve this issue?

Thanks,

Peter.

PS: Here is my code (I am using RAD2010Q1.NET3.5)

protected override void OnInit(EventArgs e)

{

base.OnInit(e);

try

{
...
...

RegisterUpdateControl();

}

catch (Exception ex)

{

DisplayErrors(ex.ToString());

}

}

protected override void OnLoad(EventArgs e)

{

int height = 0;

try

{

base.OnLoad(e);
......
.....

Test();

}

catch (System.Exception ex)

{

DisplayErrors(ex.toString);

}

}

private AjaxSetting ajaxSetting2;

private void RegisterUpdateControl()

{

ajaxSetting2 = new AjaxSetting();

ajaxSetting2.AjaxControlID = "panelTest_ID";

AjaxUpdatedControl control2 = new AjaxUpdatedControl();

control2.ControlID = "panelTest_ID";

control2.LoadingPanelID = this.ID + "loadingPanel";

ajaxSetting2.UpdatedControls.Add(control2);

this.radAjaxManager.AjaxSettings.Add(ajaxSetting2);

//panelTest_ID

}

 protected Panel panelTest;

protected Button button;

protected TextBox textbox;

private void Test()

{

panelTest = new Panel();

panelTest.ID = "panelTest_ID";

textbox = new TextBox();

textbox.ID = "textbox";

panelTest.Controls.Add(textbox);

button = new Button();

button.ID = "Button";

button.Text = "Ok";

button.Click += new EventHandler(button_Click);

panelTest.Controls.Add(button);

this.Controls.Add(panelTest);

}

RadTabStrip tap;

void button_Click(object sender, EventArgs e)

{

CreateTabTemp();

}

private void CreateTabTemp()

{

tap = new RadTabStrip();

tap.TabClick += new RadTabStripEventHandler(tap_TabClick);

tap.ID = "fdasdfasdf";

tap.EnableAjaxSkinRendering = true;

//tap.EnableEmbeddedScripts = true;

//tap.EnableEmbeddedSkins = true;

//tap.EnableSubLevelStyles = true;

InitTabs();

this.panelTest.Controls.Add(tap);

}

void tap_TabClick(object sender, RadTabStripEventArgs e)

{

string te = e.Tab.Value.ToString();

}

private void InitTabs()

{

for (int i = 0; i < 5; i++)

{

RadTab item = new RadTab("tab_" + i.ToString(), i.ToString());

tap.Tabs.Add(item);

}

}

Thanks,

I am having the same problem in SharePoint 2010, using a technique similar to the one shown in the demo site:

http://demos.telerik.com/aspnet-ajax/tabstrip/examples/applicationscenarios/loadondemand/defaultcs.aspx

If I ajaxify the tabstrip and set the updated control as the multipage, I get the above mentioned error when I try to click on one of the previous tabs.

Hi Larkin,

SharePoint has issues when the RadAjaxManager is declared at markup in a user control.
You can overcome this by adding the RadAjaxManager at OnInit event of the web part.

Additionally please add the AjaxSettings in this way:
(I am not sure what the exact settings that you have defined are, so this sample only illustrates the approach that you can use.)

private const string _ascxPath = @"~/_CONTROLTEMPLATES/SchedulerWebPartProject/SchedulerWebPart/VisualWebPart1UserControl.ascx";

protected override void CreateChildControls()
{
}

RadAjaxManager ajaxmgr;
protected override void OnInit(EventArgs e)
{

    base.OnInit(e);

    ajaxmgr = new RadAjaxManager();
    Page.Items.Add(typeof(RadAjaxManager), ajaxmgr);
    Page.Form.Controls.AddAt(0, ajaxmgr);

}

protected override void OnLoad(EventArgs e)
{
    base.OnLoad(e);

    Control control = Page.LoadControl(_ascxPath);
    Controls.Add(control);

    RadTabStrip RadTabStrip1= control.FindControl("RadTabStrip1") as RadTabStrip;
    RadMultiPage RadMultiPage1= control.FindControl("RadMultiPage1") as RadMultiPage;

    ajaxmgr.AjaxSettings.AddAjaxSetting(RadTabStrip1, RadTabStrip1);
    ajaxmgr.AjaxSettings.AddAjaxSetting(RadTabStrip1, RadMultiPage1);
}
