I am using the combobox in EnableLoadOnDemand mode. The data in the drop down has three collums (ID, Name, Address). I set my default selected item like this:
 
Me.RadComboBox.SelectedValue = "9238"
Me.RadComboBox.Text = "Smith, Jones"

I happen to have 3 "Smith, Jones"  in my database each with different IDs. When I click on the drop down, the control is smart enough to get the 3 smiths matching the text in the dropdown but the selected item in the list is always the first one. The item with the 9238 ID happens to be the third item in the list so the default selection is invalid pointing to the wrong customer confusion my users. Is there a way to get the selected item in the drop down list to match the ID that I have set as the default starting value? It seems to me this should be a default behavior.

Hello there

I am unable to render the tagcloud in a repeater; it generates the following exception:

Exception type: NullReferenceException

Exception message: Object reference not set to an instance of an object.

at Telerik.Web.UI.RadTagCloud.BindToEnumerableData

I have added some code below to replicate. In this example I have bound the repeater to a simple list.

Is there anything in the clientside api for adding and removing items?

Hello,
I am using the RadDataPager to page thorugh what is essentially a home-grown control that does not support databinding. Everything works perfectly though and I am able to Page properly, except for changing the size of the page. If I change the size of the page I get the correct page size reflected on the server-side properties. However, the issues comes when I page forward or backwards. The datapager will default to the page size being 10. I understand that the pager uses the get method to move forwards and backwards so I am unable to persist the changed page size in the viewstate. Is there any way to force the pager into using a POST method or is there a way to have the control pass the page size as a querystring variable similar to the SEOPagingQueryPageKey?  Other than this the datapager works beautifully with my non-databound control. I could resort to re-writing the URL once the PageSizeChange event is captured, but am trying to avoid that if possible.

I'm adding  nodes to the treeview at page load. Also at the same time I am adding a Label and a DropDown control to the node.

I want to disable the DropDowns for certain nodes  based on what node was checked. The Error I'm getting is :
"Object reference not set to an instance of an object."

This is because the the TreeView1.Nodes(0).Nodes(i).Count is 0. But it shouldn't be.

Does anyone know what I'm doing wrong here?


Heres how I am creating the nodes:
            For i As Integer = 0 To DsStateDistrictID.Tables(0).Rows.Count - 1
                Dim treeNode As New Telerik.Web.UI.RadTreeNode(DsStateDistrictID.Tables(0).Rows(i).Item("DistrictName").ToString)
                treeNode.Value = DsStateDistrictID.Tables(0).Rows(i).Item("StateDistrictID").ToString
                treeNode.Checkable = True

                'Add Label with StateDistrict Name to Node
                Dim lbl As Label = New Label
                lbl.Text = DsStateDistrictID.Tables(0).Rows(i).Item("DistrictName").ToString
                lbl.ID = "lbl" & DsStateDistrictID.Tables(0).Rows(i).Item("StateDistrictID").ToString.Trim
                treeNode.Controls.Add(lbl)

                'Add Color DropDown to Node
                Dim ddColor As DropDownList = New DropDownList
                ddColor.ID = "dd" '& DsStateDistrictID.Tables(0).Rows(i).Item("StateDistrictID").ToString.Trim
                ddColor = BuildColorDropDown(ddColor)
                treeNode.Controls.Add(ddColor)
                TreeView1.Nodes(0).Nodes.Add(treeNode)


            Next


        End If


Heres how I am trying to disable the drop down list:
For i As Integer = 0 To TreeView1.Nodes(0).Nodes.Count - 1
                    Dim StateDistrictID As String = TreeView1.Nodes(0).Nodes(i).Value.ToString.Trim
                    Dim ddColor As New DropDownList
                    ddColor = CType(TreeView1.Nodes(0).Nodes(i).FindControl("dd" & StateDistrictID), DropDownList)
                    ddColor.Enabled = False
Next

Hello,

I have a Horizontally split Splitter (header, content) and then the content is a vertically split Splitter (LeftNav, MainContent).
I have the MainContent RadPane set to scroll in both directions and I have followed the directions of setting the style of html, body,form to height:100% and height=100% down the hierarchy to the pane.

Inside the MainContent RadPane I have a RadGrid that is very long and therefore causes the RadPane scrollbars to show. Everything works until I scroll down and select a row in the RadGrid. Then, depending on how far down I have scrolled I get everything on the screen shifted upward. In the worst case, the screen appears to be completely blank (no content, no scrollbars). When I have scrolled just one page down and then select a row, then everything on the screen appears to have been painted off by the amount of the scroll down. For example, the header is missing and the scrollbar only goes down 2/3 of the screen.

Any ideas what is happening?

I have been trying to get the RadRotator images to display in Mozilla Firefox 3.6 but it doesn't show anything, just the background color.  Is there any solution to this problem?

I tried to mimic the example here:
http://demos.telerik.com/aspnet-ajax/scheduler/examples/radtooltip/defaultcs.aspx

However I am unable to get the tooltip to pull in the data from the event item. Can someone fill me in on how that info is passed to the class? Maybe I have a spelling error or something.

It works if I hard code the text as such:

protected

 

 

override void OnPreRender(EventArgs e)

 

 

{

 

 

 

base.OnPreRender(e);

 

 

StartingOn.Text =

 

"Start Date HERE"; //apt.Owner.UtcToDisplay(apt.Start).ToString();

 

FullText.Text =

 

"Description Here<br /><br /><br />"; //apt.Subject;

 

}

Otherwise I get a JS error.

Hello,
I'm using a WebUserControl to edit/insert data into my radgrid. I experience some inconsistent behavior when I tried to access the data inside my WebUserControl. The way I access the data  is


The update/insert operation can be initiate from different control in the page, so it doesn't always go through the ItemCommand event of my radgrid. Every control that can initiate an update/insert is using ajax. Here's a part to illustrate the situation


_lbtnAdd is a LinkButton. If _radgrig is in edit mode and the user click on _lbtnAdd, I'm suppose to check for modification than act accordingly. But, code that work in other situation, doesn't work here, editedItem.CanExtractValues = false. Of course, if I tried to find my form, it stays null. Looking inside of editedItem, I can see that there is an exception inside the object:
EditManager   'editedItem.EditManager' threw an exception of type 'Telerik.Web.UI.GridBindingException'   Telerik.Web.UI.GridEditManager {Telerik.Web.UI.GridBindingException}

Going deeper, reveal:
base   {"The current EditFormType does not support the requested editing capabilities."}   System.Exception {Telerik.Web.UI.GridBindingException}

This one is driving me nuts since it come and go. How can I make sure to always be able to access the data? What can cause the exception? Is it related to event order? Please help!!!

Thank you for your time,
Louis-Philippe
