TreeListSelectColumn-- How to get column value of selected rows

Hi,

I am adding TreeListSelectColumn programatically:

Dim selectColmn As New TreeListSelectColumn()

selectColmn =

New TreeListSelectColumn()

selectColmn.HeaderText =

"select"

selectColmn.UniqueName =

"select"

RadTreeList1.Columns.Add(selectColmn)

and I have a template column for displaying Invoice # but column value is 'inv_id'

templateColumn =

New TreeListTemplateColumn()

templateColumn.HeaderText =

"Invoice #"

templateColumn.UniqueName = "inv_id"

templateColumn.ItemTemplate =

New InvTemplColumn(templateColumn.DataField)

RadTreeList1.Columns.Add(templateColumn)

After selecting few invoices I want to perform some actions like- export,print, for which I need inv_id of selected rows(inv_id is not visible in treelist), but I am not able to get inv_id of selected rows.Is there any option using which I can bind value to selectcolumn. Please let me know if you have any solution. It's very urgent.
Thanks in advance.

Second RadPane is not updating at all

RadPane2 is hidden initially on my page. However, I have RadGrid1 in RadPane1, which is visible.

So when I select a row from RadGrid1, this causes the indexchanged event method to fire. RadPane2.Visible is set to True in that method and I populate the detail fields. Using the debugger, I see values going into those detail fields. Unfortunately, on my page RadPane2 does not refresh and show me those updated fields.

What am I missing? Any suggestions?

code:
----------------------------

        public void RadDataGrid1_IndexChanged(object sender, EventArgs e)
        {
            RadGrid grid = (sender as RadGrid);
 
            if (grid != null && RadDataGrid1.SelectedIndexes.Count > 0)
            {
                int index = grid.SelectedIndexes[0].GetIntOrZeroIfError();
 
                item = grid.Items[index];


                // Detail fields 
                lblDetail_Name.Text = item["Name"].Text;
                lblDetail_Address.Text = item["Address"].Text;



                
                RadPane2.Visible = true;
            }
        }

----------------------------
Thanks,
Tammie

Retain scroll position on item delete / reset position on page change

I have a grid where I would like to maintain the scroll position when an item in the grid is deleted, but I would like to reset the scroll position to the top when the page is changed.

I think it might be easier to set the SaveScrollPosition to true and reset the scroll on page change, but I am not sure how to implement this in the code behind. I am using the "NeedDataSource" event to populate the grid.

Thanks.

Hyperlink in GridBoundColumn and updating Specific Column

I am trying to create two of my columns of telerik:GridBoundColumn as Hyperlinks. When the user clicks on the column a popup window comes with the value of the column and user can update that value. I am also using the SUM to add the columns(Price, Price2) and the Grand Total(That is sum of two columns Price, Price2).
I am able to do the SUM and the Grand Total but i am not able to make my two columns (Price and Price2) as links and when user click on the column Price or Price2 a window pops up with the value of the Column. Then the User can update the value and then it updates the SUM and the Grand Total.

Compile errors trying to remove the AddressBox from FileExplorer

Hi,

I am using the ImageManager in a RadEditor and wanted to remove the path at the top of the file area - what I believe is called the AddressBox. I found instructions on your site and copied the EditDialogs folder and its content to my project.
I modified FileBrowser.ascx and specified VisibleControls="Grid,TreeView,ContextMenus,Toolbar" for the RadFileExplorer (i.e., excluded the AddressBox).

When I try to build my solution I get the following 2 errors at lines 1771 thru 1780 in StyleBuilder.ascx:

Error 204 'Telerik.Web.UI.Editor.ColorPicker' does not contain a definition for 'ClientIDMode' and no extension method 'ClientIDMode' accepting a first argument of type 'Telerik.Web.UI.Editor.ColorPicker' could be found (are you missing a using directive or an assembly reference?) C:\Visual Studio 2010 Jim\Projects\ITOptimizerNewDev\ITOptimizerWeb\StyleBuilder.ascx 1771

Error 205 The type or namespace name 'ClientIDMode' does not exist in the namespace 'System.Web.UI' (are you missing an assembly reference?) C:\Visual Studio 2010 Jim\Projects\ITOptimizerNewDev\ITOptimizerWeb\StyleBuilder.ascx 1771

If I remove the ClientIDMode="Static" from the 4 statements that include it, the build completes successfully and I get the result I was looking for - no AddressBox.

Any idea how to address these errors?

Thanks

Jim

VS2012 Express & Telerik Controls

I have been using VS2008 Pro for several years now. Today I installed VS2012 Express [for Web] on my computer. I would like to be able to do 3 things with my Telerik subscription:

Install the Telerik controls in the Toolbox so I can use them with a New Project.
Load my existing app into VS2012 and rest assured that the Telerik controls (ie. Treeview, Slider, ListBox, etc.) will just work.
Install and use JustCode, if possible.

#1 & #2 are absolute requirements. #3 is optional

Further to #1, I right-clicked in the Toolbox area of the VS2012 IDE and chose "Choose Items". On the ".NET Framework Components" tab of the dialog box I chose Browse. I navigated here: C:\Program Files (x86)\Telerik\RadControls for ASP.NET AJAX Q3 2012\Bin45
Three files appeared:

Telerik.Web.Design.dll
Telerik.Web.UI.dll
Telerik.Web.UI.Skins.dll

I tried clicking on the first two. It said "Loading the selected file(s)" Then later, when I pressed OK this message appeared: "The following controls were successfully added to the toolbox but are not enabled in the active designer:" After that, no Telerik tools appeared in the Toolbox.

While I had hoped I could save the cost of buying VS2012 Professional, this is not a very good start. Time is Money.

I would like a definitive answer from Telerik Support to my 3 questions above. Can I do all of that with the Express version of VS2012: Yes or No?
