Hello,

Is there an easy way to replace the controls in for example editform.aspx pages for list types?
What we would like to do is replace a single line text field in sharepoint with an combobox that retrieves information from a web service. The retrieving of information from a web service isnt a problem but how to bind it to a sharepoint field?
Or is the only possiblity to create a custome field in sharepoint that uses the combobox?

With kind regards,
Fabian

RadGrid + ContextMenu + RadWindow Integration

I am trying to add an image to a radgrid column that when hovered or clicked opens a context menu. The context menu contains a series of commands that i want to launch rad windows based on the command clicked and the datakey of the grid row.

I have found examples doing each thing individually but none that do this all together. Below is the code i am using. The showMenu Portion works fine. Now how do i get the contextmenuitem clicked and the datakeyname for the row it was clicked in so i can determine which radwindows to open pass it the productid for the row the contextmenu was clicked on?

Thanks for any help,
Kevin

Finding controls on dynamically loaded usercontrol

I have a modal window that loads a dynamic user control when the page is loaded. I am having trouble using the javascript getelementbyid to find the textboxes and labels on the dynamic user control. This is what I have so far:

This is the page in the modal window that loads the user control dynamically.

    
                Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load 
        
                    Dim modalusercontrol As Control = LoadControl("~/ModalUserControl.ascx") 
        
                    modalusercontrol.ID = "modalusercontrol" 
        
                    Ph1.Controls.Add(modalusercontrol) 
        
                End Sub

In the page load of the User control I am trying to find the elementbyid and fill the values. ModalUserControl is the name of the user control that I am loading dynamically into the window.

    
                Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 
        
                    Dim updateParentScript As String = "function ConfigureDialog() { " & _ 
        
                                    "var oWindow = GetRadWindow();    " & _ 
        
                                    "var oArg = oWindow.Argument;    " & _ 
        
                                    "var oArea =  document.getElementById('<%= (ModalUserControl.FindControl(""NewNameArea"")).ClientID %>').value;     " & _ 
        
                                    "oArea.value = oArg.NameValue;  " & _ 
        
                                    "var oArea =  document.getElementById('<%= (ModalUserControl.FindControl(""NewProfessionArea"")).ClientID %>').value;   " & _ 
        
                                    "oArea.value = oArg.ProfessionValue;    " & _ 
        
                                    "var oArea =  document.getElementById('<%= (ModalUserControl.FindControl(""NewLabelArea"")).ClientID %>').value;   " & _ 
        
                                    "oArea.value = oArg.LabelValue;    " & _ 
        
                                    "radWindow.Argument = arg;" & _ 
        
                                    "}" 
        
                    Page.ClientScript.RegisterStartupScript(Me.[GetType](), "oWindow", updateParentScript, True) 
        
                    Form1.Attributes.Add("onload", "ConfigureDialog()") 
        
                End Sub

Any help would be greatly appreciated. Thanks in advance.

Safari/Chrome RadGrid Row height

Hey folks,

I have a RadGrid, In a RadPageView, in a RadMultipage, in a RadWindow (I didn't have to tell you that, but it's funny when you say it out loud! :)).

Everything appears to be fine in IE6,7,8, Firefox 2 and 3, however...

In Chrome and Safari, the Row Heights in the grid are several more pixels than in IE and Firefox. It's not a huge display issue, but an annoying one.

Also, in Opera, the row heights are actually a couple of pixels less.

I am using the built in Skin "Hay" for the RadGrid.

I've tried setting specific heights to the rows, to the grid, to the pageview, to the multipage, etc, etc, but nothing seems to affect Safari and Chrome.

Anyone have any ideas?

Thanks, Kuba

Cannot get values of cells

Hello,

We are trying to use the RadGrid like an "excel" grid, and it works fine, however when we try to loop through each cell, the "Text" property always shows up as "&nbsp". However, when we use the "ExtractValues()" method, we can get the proper values. All is fine and dandy, until we hit a column that is "ReadOnly". The ReadOnly cell does not show up in the ExtractValues variable (which makes sense), but now I am back to square one as to how to get value from the cells by UniqueName. We are using Telerik version 2009.2.826.35 (2009 Q2).

                    foreach (GridDataItem row in RadGrid1.MasterTableView.Items)         
            {         
              var cell = row["MyUniqueName"];         
              Response.Write(cell.Text); // This comes out to be "&nbsp;" each time.         
            }         

Any help in directing me in the right direction would be greatly appreciated. Thanks.

Best Regards,

Patrick

RadGrid, paging, row selection, and RadTextBox issue

I've run into (what seems to be) a fairly bad bug. I've got it down into a proof-of-concept page which follows below. On the page there's a RadGrid, a button and a RadTextBox. If you select a row and click the "Click Me" button, then the selected row's index should appear in the RadTextBox. Now virtual scroll paging is enabled, so scroll to the second page, select a row, and then click "Click Me". Here I get an exception. It appears that the RadGrid has somehow forgotten it has a row selected. Moreover, if I change the RadTextBox to a native ASP.NET TextBox the crash doesn't happen.

Any input would be appreciated.

Environment: Visual Studio 2005, ASP.NET 2.0 w/ MS AJAX extension, and Telerik.Web.UI.dll version 2009.1.609.20. (I know that there is a new version of Telerik.Web.UI.dll, but I dropped in the latest version and it didn't seem to help.)

Edit: Also this crash seems to be browser dependent. I've seen it in IE6, and on IE8 in compatibility mode. In "normal" IE8 and in Firefox the crash doesn't happen. I need it to work in IE6.

Why does this Javascript inside a custom Button Function not work?

Hi all,

i have this custom Button function which works fine for me. Bu now i want to extend this function with one check. I want to check if the inserted Div already exists and stop processing.

Here is my code:

    
            Telerik.Web.UI.Editor.CommandList["Inhaltsverzeichnis"] = function(commandName, editor, args)  
        
            {  
        
              if (document.getElementById("toc")) {   
        
                alert('Es existiert bereits ein Inhaltsverzeichnis-Tag im Content-Bereich!');  
        
              }  
        
              else {   
        
                editor.pasteHtml('Inhaltsverzeichnis<br /><br /><div id="toc">-Inhaltsverzeichnis-</div><br /><br />');   
        
                alert('Inhaltsverzeichnis wurde erfolgreich hinzugefuegt!');  
        
              }  
        
            };

The div with the id = toc definitly exists, but my code always goes to the Else part of the if statement. Whats wrong?

thank you
