Hi,
We are currently evaluating if we should use clientside databinding. In your projects I see that you are using list of classes representing tables in your getdata method. In our case we can't do that, therefore I was wondering if a more generic list type was supported. I tried returning IEnumerable, but that did not work.

[Solved] What event do I use to bind to the Insert command item?

I've got a RadGrid with an "Add" link button at the bottom in the CommandItem. What event is fired off when the user clicks that button? I've got an ItemCommand method that does things for "Edit", "RowClick", etc. but clicking on this button does not trigger that event... Also, on the other side of the CommandItem bar is the "Refresh". Is that tied to an event as well? Can't find either of those. Can someone help me out?

Thanks!

Selected Value on IE back button

I'm currently working on a form for user searching and have found an interesting behavior for the radcombobox. When a user searches the value of the selected dropdown I can get the value no problem. If the user then hits the back button the correct value is selected in the dropdown but when they search again the selected value is then changed to the first value in the list. I pasted some simple code below that works as I described. Is this a bug in the control? This is not how dropdownbox performs on the back button its selected value is its selected value.

<

telerik:RadScriptManager ID="sadsad" runat="server"></telerik:RadScriptManager>

<telerik:RadComboBox ID="tst" runat="server">

<Items>

<telerik:RadComboBoxItem Text="TESTING" Value="" />

<telerik:RadComboBoxItem Text="TESTING2" Value="TESTING2" />

</Items>

</telerik:RadComboBox>

<asp:Button ID="tstButton" runat="server" Text="TEST" OnClick="tstButton_Click" />

protected

void Page_Load(object sender, EventArgs e)

{

}

protected void tstButton_Click(object sender, EventArgs e)

{

System.Diagnostics.

Debug.Write(tst.SelectedValue);

}

Style changes in Sharepoint web part

Greetings,

I'm using the RadGrid control as part of a Sharepoint web part. I need to be able to change the font and color fopr some items. I can't seem to grasp the concept of overriding any css styles. As an example I need to change the HeaderStyle font to "Trebuchet MS" but can't seem to figure that part out. I also need to change the alternating itemstyle backcolor to "#f6f6f6", but I only get actual color names in the intellisense. So I'm assuming that I need to override that somehow.

The web part is built programatically.

If anyone can help me that'd be great.

Thanks,

-Matt

Error Loading ViewState - dynamic window creation and ajaxpanels

I have a situation where we are getting an error loading viewstate. The setup (code below) is that we have a page, using a master page. On the master page we have a radwindowmanager. That master page plugs 2 windows into its list that are common to all pages. Inside our specific content pages, we have dynamic code that reads an xml file and uses that info to add additional windows to the radwindowmanager. In this way, the master page handles making global windows available (like Help, Settings, etc.) and each content page adds whatever windows it needs to that.

Anyway, in those same content pages we also have ajaxpanels containing things like calendar controls, grids, and things like that. What I've found is that after adding all the dynamic window code, using the controls in the ajaxpanel (like going to the next month on a calendar) causes the viewstate loading error.

What's the best way to correct this problem and also follow good design for all pages that do this?

Here's the .cs for the content page that shows the windows being built dynamically. The relevant stuff is the SetupWindows method:

    
            using System;  
        
            using System.Data;

            </asp:Content>

We'll have many pages that take this approach of dynamic window instantiation, plugged into master page radwindowmanager, and multiple ajaxpanels on the content page doing "stuff."

Thx.

Attach a menu to another

Hi there,

I have a menu called "A" and I want to attach a menu called "B" to several menu items of "A", without duplicating "B".

First, I guessed there were a possibiliy to attach a menu to another menu but (tell me if I'm wrong) it's not possible.

So, I tried to put "B" in an user control but RadMenu don't allow to put an user control as menu item child.

Then, I tried to attach / copy "B" programatically to menu items of "A" but this acts as a move instead of copy.

Finally, I think the best way is to create an XML file for "A" and another for "B", and to programatically bind "B" to menu items of "A". Is anybody can confirm this option ?
