Handling RadListBox checkbox ItemChecked

I have a RadListbox with CheckBoxes set to true. What I'm doing is reading data in to the listbox from a sql database and having the checkbox be checked if the data is able to be crossreferenced with another table.

I am able to populate the listbox with data and have the checkboxes be checked or unchecked on page load. My problem is handing the ItemChecked event. I want to capture the event and pass the value of the list item that had it's check box checked or unchecked to a function in server side code. The function then either creates or deletes a record in my sql database for cross referencing.

For example I have a 4 items in the list, the items consist of a name and a value(a guid), items 1 and 3 are checked on load. When I check item 2 how do I capture the check event and then pass the GUID value to the code?

I attempted to follow the instructions listed here: http://www.telerik.com/help/aspnet-ajax/ajax-client-side-api.html but I had no luck in getting it to call the function much less figuring out how to pass the information I need in the arguments.

How to use Response.Write avoiding ParserErrorException?

Hi,

I am having a user control in RadAjaxPanel of a content page. Now i want to include an image button in the usercontrol which on clicking should export the page content to a .doc file. i tried this code :
protected void Export(object sender, EventArgs e)
    {
        HttpContext.Current.Response.Clear();
        Response.ContentType = "application/msword";
        Response.AddHeader("Content-Disposition", "attachment;filename=Export.doc");
        StringBuilder strHTMLContent = new StringBuilder();
        strHTMLContent.Append("<html>");
        strHTMLContent.Append(lbExp.Text);
        strHTMLContent.Append("</html>");
        Response.Write(strHTMLContent);
        Response.End();
    }

This is working fine in a demo application with a single button,shows the download window and exports the content but in my application, it is showing the Sys.WebForms.PageRequestmanager.ParserErrorException owing to the RadAjaxPanel used.
I went through several methods of excluding the controls, etc but none works..

Please help me regarding this..

Persisting settings and hiding columns

Hello,
I'm trying to persist my grid settings and I have a strange behaviour when I hide columns.
This is my grid settings:

<telerik:RadGrid ID="rgItems" AllowFilteringByColumn="True" Skin="Windows7"

AllowSorting="True" PageSize="10" ShowFooter="false" AllowPaging="True" AllowCustomPaging="true" runat="server" AutoGenerateColumns="false" GridLines="None" ShowStatusBar="true" EnableLinqExpressions="false" GroupingEnabled="false" Height="320px">

<GroupingSettings CaseSensitive="false" />

...
...

</telerik:RadGrid>

If I don't hide columns, all works fine and the saved and restored settings are correct. When I hide columns and save settings I see that the width of the saved columns are not correct. If for example I hide the first column and change the size of the second column, when I save I see (in debug) that the width that I have modified is assigned to the hidden column and so all the grid layout is persisted not correctly.
Is there a way to resolve this issue?

Thanks.

Image Manager w/o Insert

I am using a custom dialog to implement the ImageManager as a standalone file manager for images (outside of RadEditor). I have hidden both the "Insert" button of the FileBrowser UserControl and the "Properties" tab of the ImageManager UserControl. However, if a user double clicks on an image, it still assuems they are trying to insert the image in some content and this results in the ImageManager dialog closing. Is there a way to disable the double click for files within the FileBrowser control in my custom dialogs?
