Sorting String Fields in Radgrid....

Team,

In one of our application we are binding the dynamically generated datatable (With all Field datatypes are String) to a Radgrid.
Problem is when we apply sorting on those string fields it wont sort numerically, instead of that sorting occurs on string.

My question is without change the datatypes in datatable is it possible to change the columns of Radgrid to numeric before apply sorting..

Pls. help me on this. Client wants it immediately.

Thanks,

Grid

How to Change the Expand and Collapse Icons?

I'm using the RadTreeView control.

How to Change the Expand and Collapse Icons to be e.g. arrows instead of + and - icons?

Currently the plus and minus icons are embedded in the Telerik assembly judgying by the background-image value:

url("WebResource.axd?d=VgJdxXzsswqOdCD5rvTw9qbASzacFrx1ogUDI2C8a8ec2xoyM_TB0dE7ON7_Qufmatd1FUHdwBxJuyWB5iw6-kRks3J05ogSsFdHXjCEjQfuCDzPhAViqekZ41WXyBJy0y5vpj0JBT8YkXRnUrmL8-ofV0U1&t=634342277869187417")

are there any other images embedded e.g. arrows that I can use?

Thanks,

Support for IE7

In this thread a user claimed...

"We found elsewhere on this site that Telerik has dropped support for IE7, so the problem we are having doesn't come as a surprise."

Is this true?

jQuery chaining not working

I am using jQuery for setting controls.

var

status = $telerik.findComboBox("<%= rcbStatus.ClientID %>");

status.set_value(2);

status.set_text(

"On Order");

My understanding of jQuery (which is limited) is that I should be able to chain commands like this:

$telerik.findComboBox("<%= rcbStatus.ClientID %>").set_value(2).set_text("On Order");

But the chanined command doesn't work.

Am I missing something? Thanks for any help

Telerik Styles not being applied

Trying to get some performance out of my pages and I have the RadStylesheetManager on my masterpage.

<telerik:RadStyleSheetManager ID="StyleSheetManager" runat="server" >

<StyleSheets>

<telerik:StyleSheetReference Path="~/App_Themes/Default/Slider.Activity.css" />

<telerik:StyleSheetReference Path="~/App_Themes/Default/Menu.Activity.css" />

<telerik:StyleSheetReference Path="~/App_Themes/Default/Grid.Activity.css" />

<telerik:StyleSheetReference Path="~/App_Themes/Default/TabStrip.Activity.css" />

<telerik:StyleSheetReference Path="~/App_Themes/Default/ToolTip.Activity.css" />

<telerik:StyleSheetReference Path="~/App_Themes/Default/Window.Activity.css" />

<telerik:StyleSheetReference Path="~/App_Themes/Default/ComboBox.Activity.css" />

<telerik:StyleSheetReference Path="~/App_Themes/Default/Calendar.Activity.css" />

<telerik:StyleSheetReference Path="~/App_Themes/Default/Button.Activity.css" />

<telerik:StyleSheetReference Path="~/App_Themes/Default/TreeView.Activity.css" />

<telerik:StyleSheetReference Path="~/App_Themes/Default/Layout.css" />

<telerik:StyleSheetReference Path="~/App_Themes/Default/Styles.css" />

</StyleSheets>

</telerik:RadStyleSheetManager>

I do have this key:
add key="Telerik.Web.UI.StyleSheetFolder" value="~/App_Themes/Default"/>

The last 2 CSS files are being applied as the sites layout is OK, but none of the Telerik controls are srtyled. In the app_Themes/Default folder I have individual folders for the Telerik images.

Does anyone have any ideas?

Andy

PS. Just looked at the http in Fiddler, and the images have the wrong paths the path (as in the app settings) isn't being applied.

Problem with Persistence

Hi,

I have created a rad grid for my application. It was working fine with persistence until i added an another column in the grid.
Suppose i have 3 columns , 1,2,3 i added the 4th column in between 2 and 3. When it loads the grid without persisting it loads in the correct format but after it starts persisting it would change the order of columns to 1,2,3,4 but it is supposed to be 1,2,4,3. I couldn't find out why it is working like that.

I used this example for persisting http://www.telerik.com/help/aspnet-ajax/grid-saving-settings-on-per-user-basis.html

Any help is appreciated.

Thanks,
Nimmy.

Using RadGrid with LINQ paging

Hi,
I am trying to use RadGrid with paging, using LINQ for Entities to do paging. I am using a respository method to do this:

        public IEnumerable<TEntity> GetAllPaged(int page, int pageSize)
        {
            return _objectSet.AsEnumerable().Skip(pageSize).Take(page);
        }

The LINQ part works just fine, but when I do this, the pager on the Grid is no longer available- assuming that all the records are displayed. Is there anyway to make sure the pager ribbon is still visible, and has the correct number of pages links? Is there a way to use LINQDataSource (either Microsoft's or Telerik), which makes paging easier and much more efficient?

Thanks,

Steve

How to create a FilterTemplate progammatically?

Hi,

I need to know how to create a FilterTemplate programmatically (c#) in Business layer. In the cloumn filter row I need a textbox to enter the filter expression and a button that allow the user to reset the column filter without clearing the texbox manually. The filter options button should be not available. How to do this?
The grid will be created programmatically because of dynamic using. I have found an example to create an ItemTemplate. But whats the difference to FilterTemplate?

public class MyFilterTemplate : ITemplate....
And then?.....

Best regards,
Ralf
