Problem with refreshing controls

[Farouk]

hi,

i have a problem in my scenario: when i call a radwindow, after closing this and handling the closing event in javascript, i call a a ajax request from the RadAjaxManager:

function OnClientClose() {

// After Closing the dialog: AjaxRequest

$find("<%= manager.ClientID %>").ajaxRequest("ClientClose"); }

then codebehind:

protected void manager_AjaxRequest(object sender, AjaxRequestEventArgs e)
{
    switch (e.Argument)
    {
        case "":
            //refill combobox, enable button,...
        break;
    }
}

so when i watch the control propertys(from combobox) in codebehind, everything is allright but in the browser nothing is updated...

when i call the RadAjaxPanel.RaisePostBackEvent(""); from the RadAjaxPanel that encloses all controls, the controls are updated in the browser, showing new entrys and activation status but i can't open the combobox or in an other scenario i can't click the treeview nodes...

so my question is, why are the controls in the browser in a status like freezing, when i call the RaisePostBackEvent method

or

is there an other way to update controls like combobox or treeview like the rebind of the datagrid???

sorry for my english..

Hi Bastian,

Please check out if you have added ajax setting where the RadAjaxManager updated the controls you change in the manager AjaxRequest event handler.
Additionally, make sure you are not updating same page content with RadAjaxPanel and RadAjaxManager same time.

I hope this helps.

Kind regards,

hi Iana,

ok thx for the advice with the double RaisePostBackEvent calling, after i call the ajaxrequest in js from the panel, not from the manager, all works fine...

now i have an other problem, with ajax ;)...

i try to update a ajax-panel that is contained in the master page and encloses a treeview. ok, i set the ajaxrequest of the panel, for every contantpage in the page load event, like here:

protected void Page_Load(object sender, EventArgs e)
{
  if (!this.IsPostBack)
  {
     //the event handling
     ((Telerik.Web.UI.RadAjaxPanel)this.Page.Master.FindControl("treeViewPanel")).AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(ContentPage_AjaxRequest);
  }
}

//and the necessary method
public void EmailFolder_AjaxRequest(object sender, AjaxRequestEventArgs e)
{
}

but when i call the ajaxrequest in javascript,

window.ctl00_treeViewPanel.ajaxRequest("ClientClose");
//no error appears

the programm don't come to the event-handling method... ahm i mean the EmailFolder_AjaxRequest method would not be called... (omg, my bad english ;) )..

is that a problem with the interaction of the masterpage, or what could be the problem??

Hello Bastian,

Try removing the if(!IsPostBack) clause and see if it makes any difference:

protected void Page_Load(object sender, EventArgs e)
{
  ((Telerik.Web.UI.RadAjaxPanel)this.Page.Master.FindControl("treeViewPanel")).AjaxRequest +=
  new RadAjaxControl.AjaxRequestDelegate(ContentPage_AjaxRequest);
}
