The target 'Control 1#RadChart1' for the callback could not be found or did not implement ICallbackEventHandler

[ajmal]

Hello,

When I add programatically radchart control and see the chart control on given page. I had found this error:

"The target 'Control 1#RadChart1' for the callback could not be found or did not implement ICallbackEventHandler"

So, please let me know what's the issue.

Hi fellows!
The poblem happnes when you add the control programmaticlly as ajmal wrote.
It happenes for example when control added at button_click event.

protected void Button1_Click(object sender, EventArgs e)
{
    Uc uc = (Uc)this.LoadControl("Uc.ascx");
    PlaceHolder1.Controls.Add(uc);

}

This event places the control on the page but  not in the controls tree.(Thus it cannot be found)
Solution:to place it at PageLoad that comes in responce of Button1_Click postback

protected void Page_Load(object sender, EventArgs e)
{
    if (IsPostBack)
    {
        Uc uc = (Uc)this.LoadControl("Uc.ascx");
        PlaceHolder1.Controls.Add(uc);
    }
}

Good luck

I am facing the problem in dynamic loading of RadControl.

I loading it in the page load event.

and in other case i am loading it in protected void lvDataViews_ItemDataBound(object sender, ListViewItemEventArgs e) event.

Microsoft JScript runtime error: The target 'ctl00$ContentPlaceHolder1$lvDataViews$ctrl0$ctl00$0$cvReportData' for the callback could not be found or did not implement ICallbackEventHandler.


Please provide the solution


thanks

Hi pallav,

Did you try the solution provided by shootermv in his last reply in this thread?  I was able to implement it successfully in a project of mine a while ago.
