Hi,

When i try to build Telerik.Web.UI dll in release mode i am getting the following errors:

The "CompressorTask" task could not be loaded from the assembly C:\inetpub\wwwroot\Controls\RadControls\MSBuildTasks\Yahoo.Yui.Compressor.dll. Could not load file or assembly 'Yahoo.Yui.Compressor, Version=1.4.0.0, Culture=neutral, PublicKeyToken=f8b4b81ec75097e2' or one of its dependencies. Strong name validation failed. (Exception from HRESULT: 0x8013141A) Confirm that the <UsingTask> declaration is correct, and that the assembly and all its dependencies are available.

Can you please advice.?

Client Instance Name

Hi everybody,
I'm evaluating different toolkits and I see DevEx has really nice feature: ClientInstanceName. Essentially, the name you assign for that property in any control is available for you in javascript without needing to do something like

    
            var myControl = $find('<%= MyControl.ClientID %>');

ClientInstanceName lets you simply call "myControl" without having to worry about that extra step. This not only helps make the code cleaner, but also to separate it in a javascript file, as opposed to a script tag in a page.

Is there something equivalent to this in this toolkit? Are there any plans to implement such a feature in upcoming versions?

Thanks

Sorting Issue with TemplateColumn

Hi
I am running into an issue while sorting a template column.I assigned all of the properties which is relate to sosrting in Grid. I managed to declare the template column as below

    
            <telerik:GridTemplateColumn HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="Left" HeaderStyle-Width="18%" 
        
            HeaderText="Address1" SortExpression="Address1" DataField="Address1" UniqueName="Address1" GroupByExpression="Address1 Group By Address1" AllowFiltering="false">  
        
            <ItemTemplate> 
        
            <asp:Label ID="lblAddress1" runat="server"></asp:Label> 
        
            </ItemTemplate> 
        
            </telerik:GridTemplateColumn>

I also used to retrieve the data from DB and bind the same with the label control in the ItemDataBound event of the grid. The sample coding snippet i mentioned below..

    
                       if (e.Item.OwnerTableView.Name == "Sales")  
        
                        {  
        
                            if ((e.Item.ItemType == GridItemType.AlternatingItem) || (e.Item.ItemType == GridItemType.Item))  
        
                            {  
        
                                DataSet dsFirms = (DataSet)Session["Sales"];  
        
                                DataRowCollection drLocal = dsFirms.Tables[0].Rows;  
        
                                System.Web.UI.WebControls.Label lblAddress1 = (System.Web.UI.WebControls.Label)e.Item.FindControl("lblAddress1");  // Address1  
        
                                if (iCount <= drLocal.Count)  
        
                                {                          
        
                                    lblAddress1.Text = drLocal[iCount]["Address1"].ToString();                         
        
                                }  
        
                                iCount++;  
        
                            }  
        
                        }

So since my project is subjected to bind as above mentioned scenario,please guide me to soleve the problem

--Thanks In Advance

Unfortunatly it seem i can't get correct informations with the get_appointment method.
In the redirect page, i have in the url idEvent=undefined and not the id's appointment.

Any idea?

Thanks a lot!

Prevent RadGrid Postback

Hello,

I have a web page with several individual buttons and also several RadDocks that contain their own RadGrids, all of which are in an UpdatePanel. On this page, there is quite a bit of functionality that happens on the Page Load Event.

Now for the individual buttons themselves, I want the page to Postback like normal to reload the page. However, I don't want to Postback to occur when the user is working with one of the RadGrids. Currently, when the user adds, edits or deletes a record in one of the RadGrids, this causes a Postback of the page and negatively affects the performance of the overall web page.

I am using the RadAjaxManager as well:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
<ajaxsettings>

         <telerik:AjaxSetting AjaxControlID="RadGrid1">
              <UpdatedControls>
                  <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />
              </UpdatedControls>
         </telerik:AjaxSetting>

</ajaxsettings>
</telerik:RadAjaxManager>

Is it possible to have the RadGrid not Postback so that the performance is not negatively affected? Any siggestions, tips or work-arounds would be greatly appreciated!

Problem when dropping a custom control

Hello,

We have a custom control that shows an error in design mode when dropped on RadMultipage / Radpageview:

"Exceptions occured. Impossible to modify the collection of controls during databinding during phase load, init ..."

whereas it works out of it.

The custom control is a custom drop down list that calls a webservice.

Thanks.

                        } 
        
                    }

as you see in the attached image, the GridTemplateColumn DataField="message" is missing its gridlines in some rows. i dont know why its doing that. all other columns show their grid lines.
