As you might have know, in Visual Studio ASP.NET built-in control, there is a WebControl which is a base class for all webcontrols in ASP.NET.  Is there any equivalent base class like that for Telerik RadControl?

Thanks

Hi,

I have a problem exporting a grid to excel.
All works fine but the excel file is empty.

I can confirm that NeedDataSource event is raised and data come from repository when the export button is clicked.
This is the code for export:


And this is the page code:


Excel file is generated but with <Row></Row> tags empty.
I'm using Q2 grid.

Hi, i'm developing a RadListView with a pagination performed by a stored procedure that calculates: page index and items loaded within the RadListView. I've noticed that navigation of the RadListView increase the browser's memory process for each async postback.

How can i reduce this memory unnecessarily occupied?

Hi,

I have a problem with grouping in a radGrid.  When I try to add the grouping, I get the error message "Field xxx not found in the source table".  However, when I remove the GroupByExpressions, the grid populates correctly with the field that was "not found" when the GroupByExpressions were present.  I am using a needDataSource to bind my data as suggested in a previous post since I am pulling the data from an api.  Any help would be greatly apreciated.

I have a radUpload control
I'd like to check file name with extension (SomeName.txt) on Client side (JS)
is there a buildin function that i can use to get filename, NOT entire path.

This code returns entire path i.e (C:\Users\Dev\Documents\SomeName.txt)
i Just need file Name.

or Anyone can suggest RegEx to extract file name????
Basically i need to validate that File name doesn't contain specific character "#".
 
Thanx.

Hi Support,

I have kept the following options
AdvancedForm-Enabled="true" AdvancedForm-Modal="true"  StartInsertingInAdvancedForm="true"
                        StartEditingInAdvancedForm="false" in my rad scheduler, but I am unable to view the advanced edit form on double clicking an appointment. Please let me know whether I am missing any option . Please help.

Thanks in advance.

We are currently data binding our grid to an Entity Framework list of objects using the NeedDataSource. There are 160,000 objects with a good amount of data per object. We have paging and filtering by column turned on. There are no groupings or hierarchy. We also have popup editing of rows.

So our question is how can we get the best performance from RadGrid with this setup? Currently, paging through results or doing a filter search on the "Name" of the object is pretty slow. It also takes a two to three seconds to open the popup window to edit the record and same when submitting the edits.

We looked at your Performance demo using LINQ but saw you Cache the entire collection of objects. I don't really think caching a collection of 160,000 objects with some properties being a lot of text sounds like a good idea. I would also think you'd lose performance by not making use of SQL's indexes.

What would you recommend? Would we get performance increases if we used a LINQDataSource instead of assigning our context and objects using the NeedDataSource?

Can the Grid pass Take() and Skip() methods to the database for paging so it is faster?

And it takes about 5 seconds for the grid to return results from a StartsWith filter. Doesn't that simply do a ColumnName LIKE 'SearchTerm%' to the database? Doing this in SQL Management Studio returns instantly but is very slow in RadGrid.

For the RadTreeView, I see that we are able to interate through each node and then apply a ForeColor to each node
with the following:

e.Node.ForeColor = System.Drawing.

 

Color.DarkSeaGreen;

 

But, how can we pass a hex color as I do not see how this is possible. - example : e.Node.ForeColor = '#fff'

Next, how is it possible to change a Node's text Font Type to say Ariel or any other font types.

Thank you in advance
 

Hello,

I have a problem with the radeditor control when it is placed into the radgrid editform (Please view the attached image).
As you can see in the attached image, the radeditor sometimes (Allways on the first time I click on "Add new record" or "Edit") not displayed well.

Here is my code:
Default.aspx:

SubUserControl.ascx:

Style:

Note: As i sayed, the radeditor is displyed as it is shown in the screen shot just on the first time I click "Add new record" or "Edit". After that the radeditor will be displayed normally even if I click the "Add new record" or "Edit" linkbuttons.

Please, I need your help to solve this problem,
It is appreciatede to send me the modified code.

Regards,
Bader

Hi, we noticed the following bugs occurring in the current release of the RadEditor that occurs both on our website and in this demo :
<http://demos.telerik.com/aspnet-ajax/editor/examples/default/defaultcs.aspx>

• Under Safari: The underline button is acting weird, when you press it and no text is selected, the next typed text will be underlined but the button won't look pressed. If you toggle it the next typed text won't get underlined but the button will look pressed.
• Under both Opera and Chrome: When you press enter, the scroll-bar won't follow
• Under Opera and Safari, sometimes, you can't un-highlight text when it's pasted from word
• Under Firefox, if you first click on the background color button and then type text, the text will not be highlighted

Theses bugs happen under both these versions of the RadEditor
v2011.2.712.40
v2011.1.519.35
