Since our project uses the sharepoint masterpage we cannot add the ajaxmanager to the masterpage. We have a main composite page that contains a tabstrip and 10 user controls. Right now im trying to get the user controls to use ajax and put one of user controls inside a RadAjaxPanel. this works fine on the first attempt (hit a refresh button) but after that the control is locked down and no other requests work on it.

What would the recommended approach be for using a sharepoint master page with ajax? I couldnt find any examples that really deal with it.

multi drop downs

I'm having issues with dependent drop down menus. I have 2 dropdowns, Category and SubCategory. In a straight ASP.NET control page I have it working perfectly with OnSelectedIndexChanged.

With the telerik version though I have to assume something to do with xhtml output (the produced code is an <li> instead of an< option>)or xhtml page (the example on the website has simply Xhtmlpage instead of System.Web.UI.Page) or even the change from selected index to select value (as in LoadSubCategories(e.Value.ToString())) is causing the the first dropdown menu to not load. As you might expect, the second menu can not load unless the first loads.

Here's is the code...any help would be appreciated. Thanks!

Tab to next Tab Page

Is there a way to have the tab strip goto the next tab when a user hits the tab key on the last control on the current tab? From a heads down data entry perspective, it would be nice to be able to just tab from one tab to the next.

Thanks!

DetailTables count is 0

Hi,

I have a DetailTables in my grid, and each row in the DetailTables has a checkbox. I am strugging to loop through each row to see if the checkbox is selected or not. I have tried looking for a suitable example but could not find any. Here is my code:

protected void btnClientAccounts_Click(object sender, EventArgs e)
{
   foreach (GridDataItem item in rgResults.MasterTableView.DetailTables[0].Items)
   {
      CheckBox chkSelectAccount = (CheckBox)item.FindControl("chkSelectAccount");
   }
}

The item coun stays 0. I'm not sure.

Please can some one help me?

Thanks
Brendan

RadGrid and Related Grid Example using LINQ

The example of the RadGrid with Related Grids is excellent. See http://demos.telerik.com/ASPNET/Prometheus/Grid/Examples/Programming/SelectedValue/DefaultCS.aspx

Couple of questions:
1. Is there an example using Linq? Having some troubles making this work with Linq.
2. Can this be used for updating? Assume yes but just checking.

Thanks
Brad

ajax panel scroll issue

I am having an issue with an ajax site scrolling...

i have a tree menu that updates a user control.. the user control houses 2 datalists that have images as the items....

when you click on an item.. it opens a detail panel for that item..

only thing is... if you scroll down and click on it, in ie... the detail window comes up but you have to scroll up to see the whole thing.

http://maximlrg.com/uomo/search

click on Men, and then click on cotton... scroll down to the bottom of the list and click on an item...

you will see the behavior...

i only notice it in ie7 on a laptop that doesnt have a lot of vertical screen space...

I placed a javascript routine that brings the scroll window to the top... but i was only able to attach it to the item command for the datalist... and that brings the items to the top and then displays the detail window.. that works.. but it is quirky...

Is there another solution?

thanks and regards,

jeff

Edit Context Menu Returned Markup

I am trying to edit the markup returned from the Set Image Properties context menu (I am trying to append an additional style on the img tag). I have added the below to my tools file:

</contextMenu>

and the following javascript beneath the RadEditor on the page:

RadEditorCommandList["SetImageProperties1"] =
function(commandName, editor, oTool)
{
    editor.Fire('SetImageProperties', callBackFn);
    function callBackFn(result)
    {
        if (result)
        {
          alert(result);
        };
    }
};

This is currently giving me a js error Object does not support this property or method. Also the icon URL is not displaying in the context menu even though it is valid and how would I put custom text in the context menu text? I was trying to use this approach which is similar to the following thread: http://www.telerik.com/community/forums/thread/b311D-taged.aspx

Thank you for your help.
