Hierarchical Grid: Show headers of DetailTable in MasterTableView?

Hello,

is it possible to show the headers of the DetailTable in the MasterTableView only once?

You can see my grid in the attachment. I want to show all blue rows on top of the grid. The filtering functionality is required as well. Is there a way to do this? Any help is appreciated.

How to handle a exception error in c#?

Hi,

I use the "try...catch" in order to save the data to the server.
And I was exception handling in the "throw ex".

However, this doesn't display page when an error occurs.
So I have to debug to check the exception message.

In such a case, do I need to process How?

here my code.

aspx

<title></title>

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

<script type="text/javascript">

function Update() {

var batchManager = grid2.get_batchEditingManager();

batchManager.saveChanges(grid2.get_masterTableView());

}

......

<body>

<form id="form" runat="server">

<div>

GridCheckBoxColumn has a literal filter value

Hello, I bind a grid programmatically using NeedDataSource.
Filtering, sorting, paging, all work perfectly.

myDataSource = new ObjectDataSource { ... };

myDataSource.Selecting += SourceSelecting;

...

private void SourceSelecting(object sender, ObjectDataSourceSelectingEventArgs e)

{

e.InputParameters["filterExpression"] = myGrid.MasterTableView.FilterExpression;

}

I have problems when SQL Server BIT columns are bound to a GridCheckBoxColumn and I allow filtering on it.
The problem is that in previous code the filter expression is something like ([MyBoolColumn] = True).
This expression is not valid when I pass it to SQL Server, because True is not a valid bit value (should be 1).

Is there any way to tell the grid to use 0/1 as filter values for GridCheckBoxColumns instead of False/True?

Thanks

Show/Hide TreeView Ajax Issue

I followed your demo here:
http://demos.telerik.com/aspnet-ajax/ajax/examples/common/showingwebcontrols/defaultcs.aspx

And got the show/hide to work great, however I have problems with the treeview after the showing/hiding. I can't click on most of the checkboxes any longer. See the screencast below.

http://screencast.com/t/irAwzZBFg1

Any ideas?

Allowing user to specify x, y position for new image or text

Hello,
I've got a basic project working that allows a user to "stamp" custom predefined text or statuses on an image. I have it now always adding the new text in the upper corner, but that may not be a good place for different images. Does anyone have any suggestions on a good way to allow the user to specify the position of the text before it is inserted. Ideally, I could allow them to drag it to the new location after I add the text, but from other posts, it doesn't appear that is possible.I'd like to avoid a custom popup dialog if I can, because right now, they just click a custom icon, and it stamps the predefined data.
Thanks,
Adrian

Strange Behavior When Removing Bulleted Lists

I am seeing weird results when removing bulleted list items (either ordered or unordered). I am using NewLineMode="div" because we want to wrap our blocks in div tags instead of paragraph tags. But, when removing the bullets, it wraps them in paragraph tags instead of divs like we want and would expect. But, I have also tried the demo at http://demos.telerik.com/aspnet-ajax/editor/examples/overview/defaultcs.aspx and it properly wraps the removed entries in the NewLineMode value of div that I had selected. Right now, I am using the 2014.3.1209.35 version of the Telerik AJAX ASP.NET controls. To eliminate other variables, I made a test project with just a page with a RadEditor on it. I have tried this in IE 11, Firefox 36, and Chrome 41. I am confused that the demo behaves differently than the control in my project.

Steps to reproduce:
- Set the NewLineMode to div.
- Create an ordered or unordered list with 6 items. It does not matter if you start the list first and then press the Bulleted List or Numbered List button or highlight the entries and then press the button. The HTML looks like this:
   <ul>
        <li>One</li>
        <li>Two</li>
        <li>Three</li>
        <li>Four</li>
        <li>Five</li>
        <li>Six</li>
   </ul>
- Highlight the 3rd and 4th entries.
- The 3rd and 4th entries will be removed from the bulleted list and the list broken into two pieces. The entries are wrapped in paragraph tags instead of div tags. Since I am using NewLineMode="div", I would expect Three and Four to be wrapped in div tags.
   <ul>
        <li>One</li>
        <li>Two</li>
   </ul>
   <p>Three</p>
   <p>Four</p>
   <ul>
        <li>Five</li>
        <li>Six</li>
   </ul>

This is what I would expect instead:
   <ul>
        <li>One</li>
        <li>Two</li>
   </ul>
   <div>Three</div>
   <div>Four</div>
   <ul>
        <li>Five</li>
        <li>Six</li>
   </ul>
