I have a Radgrid with almost 7000 items. So when i click on the export to excel button, it takes quite some time before the file is created and the download message appears.

So i thought on making an loading screen. I've used ajax loading panel. The problem i have is that when i click the export button it triggers the loading panel, but after the download message appears, it stay's "on".... I think it's because the update control (the grid) isn't been updated....

I've search and search, but i can't seem to find a work around this or even an other way to achieve this.

Thanks in advance for the help!

Every body, please help me.

 I made a (asp.net) UserControl ,  I drag a grid into the usercontrol and rendering this usercontrol in a asp.net page.
Now my question is: I want to export the data from the grid to Excel ,and I follow the instruction within grid help documnet. But I did not see any popup window after I click  the export button.
I use version: RadControls for ASP.NET AJAX Q1 2011
my code snippet here: 

        <MasterTableView Width="100%" CommandItemDisplay="Top">
            <PagerStyle Mode="NextPrevNumericAndAdvanced" />
            <CommandItemSettings ShowExportToExcelButton="true" />
        </MasterTableView>

I have a problem getting this right.

function requestStart(sender, args) {
                currentLoadingPanel = $find("<%= RadAjaxLoadingPanel1.ClientID %>");
                //debugger;
                if (args.get_eventTarget().indexOf("grdTekGrid") >= 0) {
                    currentUpdatedControl = "<%= grdTekGrid.ClientID %>";
                }
 
                if (args.EventTarget.indexOf("ExportToExcelButton") >= 0) {
                    args.EnableAjax = false;
                }
                //show the loading panel over the updated control
                currentLoadingPanel.show(currentUpdatedControl);
            }
 
            function ResponseEnd() {
                //debugger;
                //hide the loading panel and clean up the global variables
                if (currentLoadingPanel != null)
                    currentLoadingPanel.hide(currentUpdatedControl);
                currentUpdatedControl = null;
                currentLoadingPanel = null;
            }

This is the code i've seen in many threads.

The problem here is if i let this stay as it's is, the loading panel just stucks there (the circle does not move, it's "frozen") and after a while pop-ups the prompt open/save excel file. But even after the popup the loading panel doesn't disappear.... 

If i remove this bit:
if (args.EventTarget.indexOf("ExportToExcelButton") >= 0) {
                    args.EnableAjax = false;
                }

The loading panel works great, but instead of being prompt to open/save the file, the contents of the table that is created is loaded/pasted in the grid itself....

Thanks in advance for all the help

Hi I am working with RadTooltipManager control. i am using the position as "BottomRight". it's working fine at the top of the page   onmouseover  event of the some text. But at the bottom of the page it's not showing properly like showing somewhere on the page instead of Bottom of the selected position. Please let me know what's the wrong with this code.
<telerik:RadToolTipManager runat="server" ID="RadToolTipManager1" Position="BottomRight" onajaxupdate="OnAjaxUpdate" ShowEvent="OnMouseOver" Visible="false" Skin ="Outlook" ManualClose="true" Height="220px" Width="220px" RelativeTo="Element" ></telerik:RadToolTipManager>

Thanks in Advance,
Chinna..

The grid has grouping and hierarchy. When the grid is loaded initiially, all hierarchy rows are collapsed.  When a grid group is collapsed and then expanded, all hierarchy rows get expanded. I don't see any configuration changes to stop it. Some of the related markup:

<MasterTableView HierarchyLoadMode="Client" HierarchyDefaultExpanded="false"  
GroupLoadMode="Client">
 ExpandCollapseColumn Visible="True">
 </ExpandCollapseColumn>

The more items you add to a grid the longer it takes to invoke a GridButtonColumn event is there some means to ensure that the button does a postback without posting back the entire grid??

Running VS2010 (SP1) using the latest Telerix Q3 2011 controls, ASP.NET version 4, AjaxControltoolkit version 4 on a Windows 2008 R2 installation.
I am using a web service:-
   [ScriptService]
   [WebService(Namespace = "http://tempuri.org/")]
   [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
   public class PS_AdminWebInterface : System.Web.Services.WebService
   {
      [WebMethod(EnableSession = true)]
      public string[] GetSessionString(string sessionKey)
      {
         string[] results = new string[2];
         results[0] = sessionKey;
         try
         {
            if (Session["ClientID"].ToString() == "0")            //Logged in users only
            {
               results[1] = "";
               Session["ErrorOccurred"] = true;
            }
            else if (Session[sessionKey] == null)       //Does key exist
            {
               results[1] = "";
               Session["ErrorOccurred"] = true;
            }
            else
               results[1] = Session[sessionKey].ToString();
         }
         catch
         {
            results[1] = "";
         }
         return results;
      }
}

I have debugged the web service call and it is definitely being called and no exception is raised - however the javascript call :-
PlumSoftware.PS_AdminWebInterface.GetSessionString(ps_interface_sessionKey, GetSessionString, OnTimeOut, OnServiceError);

fails in the following function:-
function GetSessionString(result)
{
   if (result[1] != "0")
   {          //Data changed
      ps_interface_keepalive = 0; //Reset keepalive
      __doPostBack(ps_interface_postbackcontrol.value, result[1]);
   }
}

the result returned is always null

I have spent a few hours looking through your forums but have found no clues as to why this would be happening.

I have 2 VB projects one for the web application and the second is a library class project that include embb resources.

I have created a composite control which combine RadControls and ASP controls. This control finds the RadScriptManager and add a script reference of java script file using its assembly name and file name (i.e. assembleyname.filename.js). As long the JS file in located in the project's root directory, it works well, but when I move the JS file ot another directory (and update the AssemplyInfo file as well i.e. assemblyname.directoryZ.directoryY.filename.js ) the RadScriptManager cannot find it.


BTW, it work fine when I have a composite control of ASP server controls use ASP Script Manager to upload embb javascripts

Any idea what is the problem ?

Made a mistake in the title, I meant CheckBox


Hello. 

I have a boolean value in a table that I would like to have the user edit by clicking a checkbox in a row of data. The GridCheckBoxColumn would be perfect but for some reason it cannot be edited. 

I made a checkbox in a template column and I can databind it to show the existing value, but I am struggling with having the value save back do the database when changed. What is the most simple way to achieve this, while using AJAX so the page does not reload? 

Is there any way to put the GridCheckBoxColumn in edit mode like when the EditCommand button is clicked? 

Thanks
Michael

Hello,

I am using the below statement to bind a column of rad grid.

dr["Options"] = string.Join("<br />", item.SelectedOptions.Where(q => item.ItemOptions.Select(u => u.FirstOrDefault().Key).Contains(q.Key)).Select(x => string.Format("{0} : {1}", x.Key, x.Value)).ToList());

GridBoundColumn: 
<telerik:GridBoundColumn DataField="Options" UniqueName="Options" HeaderText="<%$ Resources:Options %>"><HeaderStyle Width="113px" /></telerik:GridBoundColumn>

'x.Value' is supposed to be not more than 26 characters. The problem is, if the value is more than 22 or 23 characters, the remaining characters are shrinked out. I cannot increase the width of the column, due to lots of other stuff on the page. All I could think of is to have line-break styling. But I don't know how that is possible. Any help would be appreciated... 

Thank you
Saquib.
