Make Image Manager pre-open sub-folder

If I have for example:

RadEditor1.ImageManager.ViewPaths = new string[] { "~/images" };

RadEditor1.ImageManager.UploadPaths = new string[] { "~/images/2011/06" };

RadEditor1.ImageManager.DeletePaths = new string[] { "~/images/2011/06" };

How do I make the image manager automatically default to the "~/images/2011/06" subfolder when it is opened? It seems to default to displaying the root ViewPaths folder every time, so the user has to each time drill down to the subfolder for every image to be uploaded or inserted.
There are many subfolders and I would like that when the image manager opens, it pre-selects the folder which the user can upload into.
Is that possible?
My scenario is that the users have read-only access to all images, but can only upload/delete in the current month, so it would be good to pre-select that month.

RadEditor adding a <br> tag automatically at the end of contents

Hello,

I am using rad editor on one of my page. I am adding RadEditor in a div which is sortable with jquery. Users can change the order of different divs on that page.

My problem is that when user moves some div up or down the editor adds a <br> in the contents. I have no idea why it is happening, can anyone help me to avoid this behavior!!

Thanks

RadToolBar combining vertical and horizontal layout

Hello,

I know that you can set the orientation of a RadToolBar to Horizantal cq Vertical.
But is it also possible to do that within one RadToolBar? I want to align a couple of RadToolBarButtons Vertical and other RadToolBarButtons to Horizontal.

So you get something like this (on 1 RadToolBar):

RadToolBarButton1 RadToolBarButton4 RadToolBarButton5
RadToolBarButton2
RadToolBarButton3

Does somebody knows a way to do this ?

Version of telerik dll that should be used in a 64 bit environment

Hi,

We have been using the telerik dll of version 2011.3.1115.35 in a 32 bit environment for developing SharePoint webparts for Sharepoint 2007 site. We are migrating from MOSS 2007 to SharePoint 2010. So would like know if the same version of telerik dll can be used in the new 64 bit environment, if not, what is the telerik version that would be compatible? We are using Visual Studio 2010 professional edition 64 bit for development.

Thanks,
Jyothi

Custom header and Custom item

Hi,

I am using the telerik asp.net ajax treelist to display data. For one of the column, I would like to display graphics display like rectangle, polygon or line for example showing progress of a task. For the same column, I would like to display a scale on its header column.

Is there a way to do this on client-side or server-side or both on the treelist? If yes, do you have an example for this? Thanks.

Best regards,
Melvis

When the page loads, i am binding the grid with empty datatable:

private DataTable CreateEmptyTable()

{

DataTable dt = new DataTable("PurchaseData");

try

{

dt.Columns.Add(new DataColumn("OrderQuantity"));

dt.Columns.Add(new DataColumn("UnitPrice"));

dt.Columns.Add(new DataColumn("ExtendedPrice"));

DataRow dr = dt.NewRow();

dr["OrderQuantity"] = 0;

dr["UnitPrice"] = 0;

dr["ExtendedPrice"] = 0;

dt.Rows.Add(dr);

}

catch (Exception)

{

throw;

}

return dt;

}

bindgrid()

{

radgrid1.DataSource = CreateEmptyTable();

radgrid1.DataBind();

}

I am getting the error as "operator * cannot be applied between string and string".
The columns are integer type in sql. How to to fix this?
Thanks
