I'm trying something very simple. I'm using a custom validator that needs to check the length of the RadEditor. I'm using Q1 2013.

Any ideas???

I get this:

Error: Unable to get value of the property 'get_html': object is null or undefined

From this:

I have an empty menu declaration and I add items to the menu client-side in response to various JavaScript events. I would like the menu items to expand up. I tried setting the DefaultGroupSettings ExpandDirection but the menu items still expand down. I have also tried setting the expand direction on the dynamically-added root menu items client-side, but I don't know if my syntax is right and this doesn't appear to work:

Hi,

Our requirement is to maintain the status of the grid when user navigates from parent page to child page. So, when child page link in the grid is clicked, we are saving entire page state (dropdown list control selected values, grid sort, display of columns etc). Upon coming back from child page, we are assigning dropdown values back to controls from session and binding the grid to object that gets data from db based on dropdownlist control values. Then we are planning to set grid state (like sort order, display of columns etc)..

For this, when saving grid state, I need to loop thru columns and get col sort order. This code is out of radgrid events. I am doing this way:

foreach (GridColumn col in RadGrid1.MasterTableView.Columns)
{
   if (col is GridBoundColumn)
     {
          GridBoundColumn gbc = col as GridBoundColumn;
           object sortOrder = gbc.SortExpression;
     }

}

I know that I sorted column. But SortExpression (if I mouse over SortExpression, is always empty).
Please let me know how to get the sort expression or sort order programatically and also how to set grid sort order.

Thanks

We are having issues when applying refreshed combo box filters in addition to using NestedViews. Once we apply filters and rebind the NestedViews will no longer open/expand.

What I believe is happening is that Prerender is being invoked for both the filter as well as the NestedView expand. In PreRender I am calling a function that refreshes our filter combo boxes to relevant options post filter and rebinds the grid. At this point the filter is != string.Empty and when the row is clicked to expand the NestedView prerender fires again and my function is again called rebinding the grid and collapsing the NestedView. My question: is there any way to avoid this collision? Would it be possible to detect who invoked Prerender or move the combo refresh to Javascript?

We want to achieve the following goals:

1. Refresh several combobox filter dropdowns after the user has filtered on a field, and rebind the grid
2. Utilize nested views after filtering

Code is below:
protected void RadGrid1_PreRender(object sender, EventArgs e)
        {
            if (RadGrid1.MasterTableView.FilterExpression != string.Empty)
            {
                RefreshCombos();
            }
        }

protected void RefreshCombos()
{
SqlDataSourceVP.SelectCommand = SqlDataSourceVP.SelectCommand + " WHERE " +                               RadGrid1.MasterTableView.FilterExpression;
            SqlDataSourceTransStatus.SelectCommand = SqlDataSourceTransStatus.SelectCommand + " WHERE " + RadGrid1.MasterTableView.FilterExpression;
            SqlDataSourceTransType.SelectCommand = SqlDataSourceTransType.SelectCommand + " WHERE " + RadGrid1.MasterTableView.FilterExpression;
 RadGrid1.MasterTableView.Rebind();
}

This is the first time I got this error.  Can someone please help?
I used a datetime picker on my form and choose the embedded skin called WebBlue.  My control is set to EnableEmbeddedSkins = true.
After I deploy the project, this is the error I get when trying to run the app:

Telerik.Web.UI.DatePickingInput with ID='dateInput' was unable to find an embedded skin with the name 'WebBlue'. Please, make sure that the skin name is spelled correctly and that you have added a reference to the Telerik.Web.UI.Skins.dll assembly in your project. If you want to use a custom skin, set EnableEmbeddedSkins=false.

Thanks for any and all help.

Hi.
Is something very curious with the RadDatePicker performance in Chrome (I have the latest version: 26.0.1410.64 m)
My code is very simple:


If you use the RadDatePicker calendar before any button click, you can use the navigation arrows quickly, but if you use the RadDatePicker after some button clicks, the arrow navigation performance starts to decrease and the calendar freezes. This issue is not present in Internet Explorer or Firefox.


On the other hand, if you add a RadAjaxPanel the RadDatePicker performance is okay even after a few postbacks if you click the button in Chrome.

Best regards.

I also have a double postback issue but I think it will be resolved once this issue is resolved. I have this radgrid that appears to be getting data but it is not displaying. After binding the grid, the grid.Items.Count is set to the number of rows expected. I'll include the ajax manager settings and grid. Thanks!

Good Morning, I have a RadGrid that inserts and updates records through a usercontrol in development pc, it works perfectly, but in the usercontrol Server does not appear when you click on "GridEditCommandColumn" or the Add Record button RadGrid.
I've also noticed that deleting a record in the server before asking me for confirmation through the RadWindows, while the development PC only delete it once results confirmed the deletion.
The development pc has Windows 7 with IIS 6.1.
The server has Windows Server 2003 R2 Standard Edition SP2
The application works with FW4 and other RadControls work well.

 have a Rad Calender. I have to apply some code logic with database and If my code logic gives me FALSE for a particular selected date of Rad Calender than I have to show that Date in RED color of that Rad Calender. In other words I have to set RED color for different dates of Rad Calender through Server Side.

For a brief view I am attaching some Screen shots that will elaborate my Scenrio
