Hi. I notice that if you input an incorrect date that the raddatepicker textbox highlights red with a yellow exclamation mark inside it. This is cool, especially when restricted for space. I have a requiredfieldvalidator that I would like to apply the same error to. Is there any way to call this from say javascript? Thanks.

Hello,
I'm trying to use the panel bar for a site navigation and still be able to use custom attributes to specify properties for the panel bar such as ImageURL, HoverImageURL, etc but still have security trimming.
My first attempt was with a site map provider but I can't define custom attributes in the web.sitemap file.
Then I tried an xml file and then security trimming didn't work.

Is there anyway to use something other than the sitemapprovider and still have security trimming.

Thanks,
Brian

Hi. What is the ClientEvents equivilant for OnClick for the RadTextBox? I can add it to the textbox itself and it works but VS gives me a warning saying the attribute isn't valid. As I said, the page still works okay, see code below. The function just clears the textbox when clicked in. Thanks.

Hi. I have several grids inside a multipage. The grids have scrolling enabled. I normally set all the columns to 1% with no wrapping and then set the column with the largest text in it to the remainder percentage. ie. 1%, 1%, 97%, 1%. This works fine with scrolling disabled. When I enable scrolling it looks like it is using the absolute size of 1% and is ignoring the text wrapping inside the header or column as all you can see is a pixel, probably the start of the text. This is a real pain, as some text looks really ugly when they wrap to the next line.


Something else I have noticed with scrolling and setting UseStaticHeaders to true, is that the line at the top of the scrollbar, between the scrollbar and header has been pushed up about 5 pixels. I have attached a screen of both issues. Thanks.

I have a treeview and I want certain nodes to be checked when the page loads and some not checked. I want to do this manually before I loop through a database so was wondering if there is any VB.NET code out there that would show me.

I was thinking something like this (using objects):

Dim Cat As List(Of Category)
        Cat = Category.GetAllCategories
        If Not Cat Is Nothing Then

               Dim C As New RadTreeNode
                      Dim CatEach As Category
                           For Each CatEach In Cat
                                 C.Text = CatEach.Category
                                 C.Value = CStr(CatEach.catID)
                                  If C.Text = "Antiques" Then
                                   C.Checked = True
                                  End If
                                  RadTreeView1.Nodes.Add(C) 
                            Next
           End If

The treeview renders nicely but the "Antiques" checkbox remains unchecked. Any help here would be very much appreciated.
               

Hello,

What I'm trying to do is essentially create a "Read-Only" combobox so the user can't make it dropdown or otherwise select anything.  I've prevented the dropdown, but they can still change it the value if they select it and then use the arrow keys to scroll down.  Is there a way to prevent this?

I have a RadUpload control in EditTemplate inside a RadGrid.
I add the client code to add addtional field with TextArea type allowing user to enter comment for the uploading file.
And that additional comment field is a required field, also only 500 characters max limited.
I want a TextArea type because I want to user to see all the text they enter and input type=text just won't do the justification.
I seem to have a problem to get the addional field's value at client side code. 

I use  
   var radGrid = $find('<%= rgGrid.ClientID %>');

to get the grid control
and  
   var radUpload = $telerik.findControl(radGrid.get_element(), "rdProfile");
to get the upload control

When I try to retrive the value of the additional field by code similar to
   var descValue = $get(radUpload.getID() + 'Title' + i).value 
I am getting javascript error saying "object needed"

Anyone can help?
I attached my code

Hi,

I have two DataTable objects that both contain the same data (first contains data before a certain change, second has the data after that change).

Assuming that both tables have the same number of records, is there any way to show differences between the tables in a nice, user-friendly way using Telerik RadGrid (or maybe any other Telerik control)?

Thanks,
Michael

I have a simple FormTemplate that I am trying to grab the values from to perform an insert/update. I am trying to grab a Listbox to create a comma delimited list of the values that it contains. When I try to access it I get a null pointer. However, I can successfully access other controls in the same FormTemplate. Anyone have any ideas?

The control I am trying to access is the lstSelectedUsers control.

Hi,

I'm adding a RadGrid to a page and am having issues getting my table data to display.

The grid is generally working, but every cell displays as 'system.data.datarowview' - looks like it's calling ToString() on the wrong object?

I am populating the grid entirely in code, but am declaring it statically in my ASPX.
I create the columns in the Page_Load method (when !IsPostback) - there is a variety of GridBoundColumns and GridHyperlinkColumns. The columns are instantiated, added to the grid.MasterTableView.Columns collection, and *then* have additional properties set.

When the time comes to populate the grid (during a partial postback event), I have a helper class that produces a DataTable object with columns with names that match the GridColumns in the grid.

I finally call Rebind() and set the DataSource of the grid to my DataTable in the NeedDataSource event.

When stepping through some of the events (I create a custom paging control), I can clearly see that my data is present in the DataSource, but it's not making it through to the grid.

If I set the grid to AutoGenerateColumns=true in my ASPX, I get duplicate columns, but the auto generated ones are displaying my cell data correctly.

I suspect I'm missing some step in wiring the DataTable columns to the GridColumns. Any advice?

Thanks,
Stefan
