I am using RadControls for ASP.NET AJAX, Q3, .net 2.0 and Visual Studio 2008. The Combobox works fine with normal page but has abnormal appearance when used with masterpage. This error is different with each skin, but in general it seems to be doubled.

I cannot post some pictures here, so I use 4shared for your reference.

Hi All

How do I get the value of the DataFieldID when a user clicks on a tab?

I can get the text value of the tab with e.Tab.Text, but I need the ID to do a lookup.

hi team

I have the following scenario

1. User control that contians a rad grid with context menu (say uc1)
2. User control that contains two web part zones.
3. Each zone contains an instance of the (uc1) control (say uc11,uc12)

the problem is that

when I choose an item from the context menu of the grid in uc11 then the effect appears in the second instance (uc12)

is there any help for the problem.?

Remark:

• we are using rad controls for asp.net ajax 2008 Q3.
• IE 7 and Firefox
• windows vista as operating system

I have a RadToolBarDropDown wich is expanded over an IFrame. When the IFrame contains a textbox with focus the cursor in the textbox is displayed through the dropdown. I have tried different skins without sucess. Does anyone know how to make the cursor dissappear?

<telerik:radtoolbar id="RadToolBar1" runat="server" skin="Outlook">
                <Items>
                    <telerik:RadToolBarDropDown Text="Drop down">
                        <Buttons>
                            <telerik:RadToolBarButton Text="Bold"  Group="Bold" ></telerik:RadToolBarButton>
                            <telerik:RadToolBarButton Text="Italic"  Group="Italic" ></telerik:RadToolBarButton>
                            <telerik:RadToolBarButton Text="Underline"  Group="Underline" ></telerik:RadToolBarButton>
                        </Buttons>
                    </telerik:RadToolBarDropDown>
                </Items>

Hi,

I am trying to assign a value to a CustomAttribute in code server side. 
So far everything else is working OK, but not sure if I need to take a different approach.


The RadScheduler1.Attribute("StaffID") obviously needs mapping to the StaffID column returned in the datatable, but doing the above is not going to work.  Do I need to loop through the datatable and manually assign this, or is there an easier method of allocating the StaffID column in the Datatable to the Custom Attribute of the RadScheduler?

Our company is fairly new at ASP.Net development and Telerik, we are looking for assistance in development of specific area's in telerik controls. 

I have a tab strip and a multip page with RenderSelectedPageOnly set to true.  When I click on a tab, I am loading a user control into an asp:Panel on the pageview.  I am re-loading the user control on a postback and that seems to be working fine.

In general, Inside the user control, where is the proper event in order to set the ajax settings programmatically to update controls on the page after an ajax call?  If I use OnLoad or PageLoad, it can't find the control to be updated.  I am currently using OnPreRender.

More specifically, inside the user control I have a grid.  In the onLoad event,  I add a RadAjaxManager.GetCurrent(Page).ResponseScripts.Add to call a client side function which issues an ajax call back to the server to load the contents of the grid.  Basically, I want to see the control, and then load the contents of the grid with an ajax call.  This is all functioning properly, however the grid is NOTupdated after the ajax call.  In the server side ajax request, I am adding an ajax setting for the mgr as the initiator and the grid as the target.  If I look at the rendered source for the page, I have 2 panels generated for the grid with the same id!  One has no data, and the other does have data.  In OnPreRender, I add an ajax setting for the grid to update itself in order to have the panel generated in the first place.

What am I doing wrong?

Thanks,

Leslie

Hello All,
   I'm new to C# and to Telerik.  My problem is that I'm modifying the supplied code to bind a datagrid to the scheduler's data.  Heres my code:

//Create a dynamic table to store the appointments' information:  
        DataTable table1 = new DataTable();
        table1.Columns.Add("ID");
        table1.Columns.Add("Instructor");

        foreach (Appointment a in RadScheduler1.Appointments)
        {
            if (a.RecurrenceState == RecurrenceState.Master)
            {
                RecurrenceRule parsedRule;
                RecurrenceRule.TryParse(a.RecurrenceRule.ToString(), out parsedRule);

                //If a recurring appointment does not have specified end time it will have  
                //endless occurrences. In this case you can explicitly put a restriction:  
                //parsedRule.SetEffectiveRange(DateTime.Now.AddYears(-1), DateTime.Now.AddYears(1));  
                foreach (DateTime occurrence in parsedRule.Occurrences)
                {
                    table1.Rows.Add(new string[] { a.Subject.ToString(), occurrence.ToString(), occurrence.Add(a.Duration).ToString() });
                }
            }
            else
                if (a.RecurrenceState != RecurrenceState.Occurence)
                {
                    //table1.Rows.Add(new string[] { a.Attributes["ID"].ToString(), a.Attributes["Instructor"].ToString()  });

                    string x = a.Attributes["Instructor"].ToString();

                    table1.Rows.Add(new string[] { a.Subject.ToString() });
                }
        }
        GridView1.DataSource = table1;
        GridView1.DataBind();
    }


The problem is that I get a NULL reference exception when trying to include the "Attributes" to the datagrid.  For instance:
   
table1.Rows.Add(new string[] { a.Subject.ToString() });  works, but
table1.Rows.Add(new string[] { a.Attributes["ID"].ToString() }); doesn't work.  Why?? And how do I get around it??

Hello,

I followed your sample code to have mutliple DetailsTables (2), but can't get the second table to show up.

When I trace the binding event of the detailstables, both get filled with data, but only one shows up. If I change the order of the detailstables, then the other table will show with data, but again the second one in the hierachie (with index = 1) wont show.

Any help would be appreciated. Here's my code.

It has a table and a repeater in the grid. When Item_databound event happens for the grid, I will bind the repeater.
The problem is that I am sure the database contains more than 1 data, but the grid only displays one. I have set paging style in, but I can't even see the previous and next link (not even disabled ones).

Can someone help me?

Many Thanks

Jerry
