    Hi

    I have some problems with radajax when I use it in webparts created for sharepoint 2010.
    I used Visual studio 2012.

    For example I have a grid with EditMode = InPlace or EditForms

    When I edit a row , fill in a radtextbox and save the form , the  save function will have the old value of the radtextbox, not the modified one.
    If I try to edit a rad datepicker, , it not shows the calendar.

    If I take out the radajax, the previous operation are working just fine.

    Can you help me please,

    I can send you a demo if you want

    Thank you !
    Hans

    Hello,

    Please note that ajaxifying the telerik controls that are positioned within a user controls works somewhat differently from the scenario when they are loaded directly on a web form. In you case, you need to move the RadAjaxManager control to the web part class, create it there and add it to the Controls collection of the web part as follows:
    private RadAjaxManager _ajaxManager;
      
    protected override void OnInit(EventArgs e)
    {
        base.OnInit(e);
      
        SetUpAjaxManagerOnPage();
      
        EnsureChildControls();
    }
      
      
    protected void SetUpAjaxManagerOnPage()
    {
        RadAjaxManager currentAjaxManager = RadAjaxManager.GetCurrent(Page);
      
        if (currentAjaxManager == null)
        {
            Page.Form.Controls.AddAt(0, AjaxManager);
            Page.Items.Add(typeof(RadAjaxManager), AjaxManager);
        }
    }
      
    protected virtual RadAjaxManager AjaxManager
    {
        get
        {
            if (_ajaxManager == null)
            {
                _ajaxManager = RadAjaxManager.GetCurrent(Page);
      
                if (_ajaxManager == null)
                {
                    _ajaxManager = new RadAjaxManager() { ID = "RadAjaxManager1" };
                }
            }
      
            return _ajaxManager;
        }
    }

    Then in the OnLoad event of the web part, get the RadAjaxManager as follows:
    RadAjaxManager _manager = RadAjaxManager.GetCurrent(Page);

    and add your ajax settings programmatically. Beforehand, you should have the user control in the CreateChildControls method of the web part and there through FindControl you should retrieve the controls to ajaxify. Keep them in a private variable local to the web part class and use that in the OnLoad event to dynamically add the ajax settings.


    Hope this information will prove helpful.

    Hello,

    The presented error most commonly appear in case the Ajax settings are not properly configured.  Therefor could you please send the code form the WebPart file and the related WebUserControl markup and code behind? Thus we will be able to revise your logic further and do our best to isolate the root cause of the issue.

    Hello Hans,

    In case the previously provided approach does not help i would suggest you to try placing the Ajax  settings in the CreateChildControls event like this:
    public class VisualWebPart1 : WebPart
    {

    RadAjaxManager ajaxmgr;
    protected override void OnInit(EventArgs e)
    {
    base.OnInit(e);
    ajaxmgr = RadAjaxManager.GetCurrent(Page);
    if (ajaxmgr == null)
    {
    ajaxmgr = new RadAjaxManager();
    Page.Items.Add(typeof(RadAjaxManager), ajaxmgr);
    }
     
    if (Page.Form != null)
    {
    Page.Form.Controls.AddAt(0, ajaxmgr);
    }
    EnsureChildControls();
    }
     
    protected override void CreateChildControls()
    {
    Control control = Page.LoadControl(_ascxPath);
    Controls.Add(control);
    p = control.FindControl("DemoPanel") as Panel;
    lp = control.FindControl("Demo_LoadingPanel") as RadAjaxLoadingPanel;
    //Find more controls to add to the ajax settings
    if (ajaxmgr != null)
    {
    ajaxmgr.AjaxSettings.AddAjaxSetting(p, p, lp);
    }
     
    }
    }

    Also please make sure that you are adding the user control to the web part before trying to access the needed controls.

    Hi Maria,

    Still it is not working and I really need this done. I cannot wait months to be done through messages. Unfortunately , you response is too long for someone who is working in a production environment and have deadlines.
    I want to send you the demo I done
    If I need to pay something, I will pay but I want the demo to be fixed.

    Please let me know asap how we can do this.

    Regards,
    Mihai

    Hi Hans,

    I completely understand the urgency of this case and will suggest you as a licensed user to open a regular support ticket where the project could be attached. As soon as we have runnable version of your application we will do our best to debug the issue locally and provide proper solution.
