Hi!

Me again!

I want to filter in a Hierarchy grid by "Tm" column
<telerik:GridTemplateColumn DataField="Tm" UniqueName="Tm" HeaderText="Light">

I follow this demo: http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filtertemplate/defaultcs.aspx.

No Hierarchy, so good.
But when I filter with Hierarchy , server error: Object reference not set to an instance of an object .

I don't konw whether there is some different when filter in Hierarchy or not?

Later I will post a screenshot to describe the situation more clearly.

Thank you!

Best wishes
Airad

[Solved] Stretch RadPane horizontally to automatically fill the screen

Hi,

Is there a way to get the RadPane to automatically stretch to fill the screen? I have a simplified example below where "paneBody" doesn't stretch to fit the screen even though I have RadSplitter height set to 100%.

<

body>

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<telerik:RadSplitter ID="Main" runat="server" Width="100%" Height="100%" Orientation="Horizontal" LiveResize="true" >

<telerik:RadPane ID="paneHeader" runat="server" Height="45px" MaxHeight="45" Index="0">

Header

<

/telerik:RadPane>

<telerik:RadPane ID="paneBody" runat="server" >

line 1 of 5

line 2 of 5

line 3 of 5

line 4 of 5

line 5 of 5

</telerik:RadPane>

<telerik:RadPane ID="footer" runat="server" Height="40px">

Image Manager return object.

Greetings:

We've developed a custom image chooser using the DialogOpener. Which we take the resulting args object and retrieve the src path and URL encode it and pass the ImageUrl to our thumbnail generator.

We build the script server side and register it to the page.

We had no issues in IE6, IE7 until the most recent updates.

function callBackFunction(sender, args){

var selectedItem = args.value.attributes[0].value;

..... custom code ....

}

the problem is, with the most recent updates, in IE7 or IE8 compatibility mode it returns null. this works great in IE 8, and FF 3.x

Would there be any chance there is another property that could be available that I am not aware of?

Thanks

3. I would like to add a collaps All rows/Expand All rows button

Editting Progress Area

Hey,

I am having a problem with the Progress Area. How can I make it not recognize files that are not supposed to be uploaded. I know that RadUpload has two different properties, UploadedFiles and InvaildFiles. The problem is is that when I am uploading files the progress area incorporates the data from the InvaildFiles as well and I cant have that happen. Is that a way to make the Progress Area only show the progress of files that are in the UploadedFiles section of RadUpload?

Changing the name of folder for selected files.

Hi!

This is what our customer services want.
When files uploaded from client to sever using

<telerik:RadUpload

they want to change the name of the folder from which they picked up the files.
And it does not allow them to do this until application closed.
On the other hand the files can be deleted from this folder, they are OK.
But folder itself is not available for changing the name of folder.

We need to fix it. I am using Silverlight project in vs2008 and WPF RadUpload control.

Best Regards!

Sorting strings as numerics

Hi,

I use Telerik RadGrid. DataSource for the grid is a web-service. One of the columns in RadGrid is a string but it contains numeric values. Though it is GridNumericColumn when I apply sorting the column is sorted as string value like 1,11,..,2, 22.
I can't change anything in datasource, including this column type.

What should I do to make the column sorted as a numeric, like 1,2,..11, 22...?

My code looks like this:

grid =

new RadGrid

{

ID =

"grdChildren",

AutoGenerateColumns =

false,

DataSourceID = ds.ID,

AllowSorting =

true

};

grid.MasterTableView.Columns.Add(

new GridNumericColumn

{

DataField =

"StringDataField", HeaderText = "ShouldBeNumericSorting"

});

Thank you very much in advanced.

Error using Telerik in a second project

Hi,

I used successfully Telerik in a project.

And i created another one, very simple web application project with just one page : Default.aspx

And even if telerik was in the visual studio toolbox, that i copied the Telerik.Web.ui.dll and Telerik.Web.design.dll and the telerik xml file also, in the bin folder, i have an error in the designer mode, on my telerik Component.

For example, for the radscriptmanager, i have

(i try to traduce it in english)

Error creating control RadScriptManager1
an unhandled exception occured,
Impossible to load the file or assembly : "Telerik.web.UI, version=2009.2.701.35, culture=neutral, publickeytoken="121fae78165ba3d4" or one of his dependances. the specified file is not found.

I have the reference to my Telerik.web.ui in the bin folder, and also a reference to the telerik.web.design.

I told myself maybe it's something missing in the webconfig, so i copied the webconfig from my first web application , wich work perfectly, but the problem is the same.

Note :
The Telerik intellisense work in "source" mode
i have the <%@ Register Tagprefix=telerik ...... namespace... etc... Assembly... %> Tag in my page.
I have also an error for Telerik.Radgrid

But everything is working fine for RadTextbox (exept i dont have the user menu on design mode)
but there isnt any error, and it appears ok when i launch the web site. (even the skin).
