Hi,

I was wondering if it is possible to apply more than one style to rows in a RadGrid. What I mean by this is I have 2 lists I am grabbing information from and adding it to a DataTable which I then bind to the RadGrid. I enumerate through the first list adding the items to the DataTable then the second and and adding the items to the same DataTable. In the rad grid I set the style property as follows:

_theListGrid.MasterTableView.ItemStyle.CssClass =

"listItemBg";

but this applies the style to all of my items.
Is it possible to set the style somewhere else so that my first list has one style and my second list has a different style and for these items to all be in the same RadGrid? If not is there a different approach I can take to have multiple styles?

Thank You

Radgrid Editmode validation with AutoGenerateColumns= true

Hi,

I have a RadGrid with AutoGenerateColumns= true. I tried adding a RequiredFieldValidator as described in http://www.telerik.com/help/aspnet/grid/grdvalidation.html.

I hooked up the validator in the ItemCreated event and this works fine (the validator performs as expected). The problem however, arises when the update button is pressed.

When in try to call:

                    item.OwnerTableView.ExtractValuesFromItem(newValues, item);  // item is GridEditableItem         

the returned values for the items with a validator attached are always null. The values for items without a validator are returned correctly.

I suspect the problem arises from the AutoGenerateColumns= true (or the documentation on the subject is just plain wrong, which i suspect is not the case). Is there a workaround for this issue?

I'm currently using Telerik.Web.UI.dll version 2009.1.311.35

Cursor (Caret) position

Hi Telerik Team,

Is there anyway to get the cursor position (caret position) in the server side code (C#) rather then in javascript? Also is there anyway to find out what text a user has selected using server side code?

I basically have 2 buttons that when clicked do certain things:

1. Needs to find the cursor position and then select all the text on the line within the text box where the cursor (caret) is placed.
2. Needs to just be able to find all the text that a user has selected

there is a third button but this just gets all the text in the text box and can easily use RadTextBox.Text

Thanks in advance

RadGrid in IE8

Hello,

I have a DNN module, and I use RadGrid from "RadControls for ASP.NET AJAX" version 2009.2 826 (Aug 26, 2009)
The grid works perfect in the IE6, IE7, FireFox and Opera. But I have trouble in the IE8.
There is not display paging for detail tables in the grid
Please look at picture, I have marked it red color, and it does not display in IE8
I have tryed to add

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />

on the page, but it did not help

Have anyone others ideas how I can fix it?

Dynamically add rows with two radcombo boxes each

HI,

I am able to add the rows dynamically and preserve the state of it when I just have one radcombo and one textbox, but when I have 2 related radcombobox's (instead of a dropdown and a textbox) for each dynamic row created. On the selection of the first radcombobox's, the second should be populated (for eg. if the person selects state in the first radcombo, the second should populate with the list of states.)
I tried doing this, I am binding the second drop down box on the selected_indexchange event of the first dropdown, that works fine, but now when I try to add a row , it gives me error on the radgrid.rebind(). Because it is not finding any items in the second radcombobox after the reload.
Any help on this.

Grid / ListView/DataList View problems in IE6

Hi,

I have a Grid in my application that shows items in a Listview/Datalist like way, as found here: Demo.
But during testing, we found that the items are not shown as expected in IE6. I *think* it has something to do with the page-size, as setting it to 10 seems to solve the problem. But as I show 4 items per row, this is not an option.

The problem:

Some text appears outside of the area it should be (see also grid2.png) and gaps appear where an item could (and should) be shown (see grid1.png).

Is there any known way of making this work in IE6 ?

[Solved] Convert an basic element in rad control

Hello,

I've got a problem with a client-side program.

I have 3 iframes in my website and I want to get a radtoolbar object to detect the button clicked.
This object is in the iframe 1 and I want it back in the iframe 2. Here is the code to retrieve:

    
            var toolbar = parent.frames["HeaderFrame"].document.getElementById("ToolBarMenu"); 
        
            for(i=0; i<toolbar.get_items().get_count(); i++) 
        
            { 
        
                    alert(toolbar.get_items().getItem(i).get_text()); // to see if the toolbar is really a radtoolbar aobject

            }

My browser gets an error (toolbar.get_items is not a function.
With this method, i retrieve a [object HTMLDivElement].

How can i get a real radtoolbar object or how can I convert this [object HTMLDivElement] in radtoolbar object ?

Thanks in advance.

RIA .NET Services Compression

I see that there is now support for the RIA services compression with the latest daily build for RadCompression. The question is, do we need special configuration to enable it, or is it automatically enabled if compression is already on?

If changes are needed, are those in the Browser file, Web config, or both?

Thanks.

[Solved] GridHTMLEditorColumn Editor Height/Width

Is there any way to set the height and width of the editor in a GridHTMLEditorColumn?

I have tried using the CreateColumnEditor event. While setting properties for other types of ColumnEditors works as expected, for the RadEditor, the height and width set are not refllected in the rendered control(s).

I have also tried using a GridHTMLEditorColumnEditor, configured with the needed height and width, and setting the ColumnEditorID of the GridHTMLEditorColumn to the GridHTMLEditorColumnEditor ID. That does not seem tb be recognized at all.

Any help appreciated.

contextmenus in toolsfile?

can someone post up a sample of what the contextMenus look like in the toolsfile? This http://www.telerik.com/help/aspnet-ajax/usintthetoolsfile.html is not very telling on how exactly to embed contextmenus. I have a requirement to only ever allow my users to pastePlainText. My toolsfile looks like this. The default set as well linked here http://www.telerik.com/support/kb/aspnet-ajax/editor/default-toolsfile-xml-file.aspx are also lacking any reference to contextMenus.
