Doing something stupid here but cant figure it out, simple page with a grid on it pulling data from an object data source. Stored proc works and brings back columns I expect as listed in the markup

But get:

Hi

Rad editor content height just overlaps to main table height, see the attachment.

This happens when we use Preview mode only (works fine in Design mode) and my page header is having 

Telerik version: 2015.1.401.45

Browser version: IE11

I will not be able to change the meta tag to Edge or IE9 as there are other components which depend on this. 

The Radeditor declaration is like below

One workaround would be to adjust the height using javascript like below

 But wanted to know do we have any other workaround for this? or this a known issue of RadEditor in version 2015?

I want to delete certains rows based on a condition while binding the grid. I am using the below code. But 'item.Visible = false;'
is not working while 'item.Enabled = false;' is working.  Any idea?


protected void userGrid_ItemDataBound(object sender, GridItemEventArgs e)
{
  if (e.Item is GridDataItem)
  {
                GridDataItem item = (GridDataItem)e.Item;
                if (item["UserName"].Text.ToString() == "SuperAdmin")
                {
                                     item .Visible = false;
                                    // item.Enabled = false;
               }

   }
}

Hi All

We're trying to update multiple RadGrid's from the client side after some user activity.

The following code works well:

However, at the same time, we also need to update second Grid on the same page, so we try this:

This doesn't work so well. The end result is:

• trgProgress is updated. trgAppointments is not.
• In fiddler, we see two posts two our page (one for each .rebind()). The first one fails with Conten-Length mismatch, expected x bytes, got 0. The second works OK and is obviously updating trgProgress.

I'm not sure what the right way to go about this is. Any suggestions?​

I would like to add two files into the radsciptmanager if the user is using a version of IE < 9.  My thought is that in the Page_Load I can test the users Browser and use an if statement to add in the 2 scripts. The reason being, these 2 files fix issues in IE 7&8 but they cause issues in IE 9&10. I have posted some code that I have tried out just not sure what I am missing or if it is possible. Is this possible with RadScriptManager? Thanks in advance.
