First Tab Remains Selected when Using Sharepoint Datasource

Hello,

Using any skin, the tabstrip loads with the first tab appearing as the currently selected tab. The status remains even if another tab has been selected. Also, the selection hand does not appear for the first tab, the tab that is in the selected state. Also, the first tab appears selected despite the SelectedIndex being set to a value greater than 0. How is this resolved? What client-side code might reset the state based on the selection event?

Any help/guidance would be greatly appreciated.

Thank you.

Doug

RADComboBox using Linq

I have used the example in MultiColumn Combo  to make the RADComboBox work with LINQ. I cannot extend the example to show the records in a related table which is used as a lookup.

Have two tables:
    Parent [table1] - List of records [parentfield1 and parentfield2] parentfield2 links to childfield1 in table2
    Child  [table2] - List of related records by parentfield2 to childfield1 [want to show these records in the ComboBox...childfield1 and childfield2]

What is described below does work in a fashion. It only lists the key field in table 1 (parentfield1).

Code is as follows:

Default.aspx

Changing radalert Icon

Hello,

I was wondering if someone could attach an example of how I can change the icon of a radalert object. I have looked at the WIndow_DynamicTemplate example project, but for the life of me, I can't even get it to run.

I am using the method to call my radalert from within an AJAX.NET update panel if that helps anyone.
I am also calling radalert from my code-behind as such:

    
            Dim scriptstring As String = "radalert('<b>" + Message + "</b>!', 200, 210, '" + messageType.ToString + "');" 
        
            ScriptManager.RegisterStartupScript(Me, Me.[GetType](), "radalert", scriptstring, True)

And the error messages I get when trying to run the sample project are as follows:
Error 2 Could not load type 'RadWindow1.Window_DynamicTemplate._Default'. C:\Documents and Settings\walkem\Desktop\057032_Window_DynamicTemplate\Window_DynamicTemplate\Default.aspx 2

Error 3 Could not load type 'RadWindow1.Window_DynamicTemplate.AlertTemplate1'. C:\Documents and Settings\walkem\Desktop\057032_Window_DynamicTemplate\Window_DynamicTemplate\AlertTemplate.ascx 1

And 1 warning:
Warning 4 Attribute 'Codebehind' in the @ Page directive is no longer supported. Convert this page to the new code-behind model by opening the Web site (project) containing the page in Visual Web Developer. C:\Documents and Settings\walkem\Desktop\057032_Window_DynamicTemplate\Window_DynamicTemplate\Default.aspx 2 24 C:\...\Window_DynamicTemplate\

Arrow key bug with textbox inside a Toolbar

I've got a Textbox within a Radtoolbar for a search functon... almost exactly the same as this example here:

http://www.telerik.com/DEMOS/ASPNET/Prometheus/Toolbar/Examples/Functionality/FirstLook/DefaultVB.aspx

Now, if you type in say:

'ggoogle', then decide you have one too many 'g's there.... just press the left arrow and watch what happens....!!

[Solved] Treeview OnNodeExpand issue with TreeNodeExpandMode.ServerSideCallBack

Hi everyone,

I have a problem with ServerSideCallback. I want to modify some properties of the node which fired the NodeExpand event in the same one.

    
                    protected void RadTreeView1_NodeExpand(object sender, RadTreeNodeEventArgs e)  
        
                    {  
        
                        IList<EntityTypeDataContract> list = GetList(e);  
        
                        if (list.Count > 0)  
        
                        {  
        
                            foreach (EntityTypeDataContract type in list)  
        
                            {  
        
                                RadTreeNode treeNode = new RadTreeNode(type.DisplayName, type.Value);  
        
                                treeNode.Expanded = false;  
        
                                treeNode.ExpandMode = TreeNodeExpandMode.ServerSideCallBack;  
        
                                e.Node.Nodes.Add(treeNode);  
        
                            }  
        
                        }  
        
                        else  
        
                        {                  
        
                            e.Node.Expanded = false;  
        
                            e.Node.ExpandMode = TreeNodeExpandMode.ClientSide;  
        
                        }  
        
                    }

The problem is until there will be a postback on the page, the state of the triggering node is not change (Expanded = true and ExpandMode = ServerSideCallback). It seems there is no refresh of the already created node during the callback ?

This sample of code works well with ServerSide expand mode but I really need the ServerSideCallBack mode.

Thanks for helping me to solve this problem.

Regards,
Sebastien

XHTML Compliance not writing compliant code to Sharepoint Database

When i preview the code in the editor i can see that the code is XHTML compliant eg: <br /> However when i look in SQL Server the code is as it used to be preinstallation of the editor, non-XHTML compliant eg: <br>.

Has anyone experienced this or have any ideas as to how i can ensure that the code i see in the editor is stored what will be written to the Sharepoint database. Are there any settings i may need to set up.
