We're using a RadComboBox within a RadGrid with an ExternalCallBackPage. Everything was working fine until I implemented the following line in the Web.config:

<sessionState mode="InProc" cookieless="true" timeout="60"></sessionState>

This caused the URL to look like:

http://WebServer/OurApplicationName/(S(kvral4fk0tipgb55bv05sn55))/Default.aspx

This part is new:
(S(kvral4fk0tipgb55bv05sn55))/

The error is "RadComboBox: load on demand callback error", then:

If RadComboBox is not initially visible on your ASPX page, you may need to use streamers (the ExternallCallBackPage property)
Please, read our online documentation on this problem for details

GridColumn looks odd on adding back a column

Hi,
   This post is related to the HeaderContextMenu online demo at http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/headercontextmenu/defaultcs.aspx . The Grid Column looks odd (row lines are missing) after performing the following steps.

      a) Goto http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/headercontextmenu/defaultcs.aspx
      b) Right click on the header of the table containing the Discount Column
      c) Using the Columns Chooser uncheck the Discount column
      d) Now expand the table with Orderid 10692
      e) Now using the Header Context menu column Chooser check the Discount column

RESULT:
     The Discount Column Looks odd without row lines as shown in the attached screenshot.

I would like to know how to make the Discount Column look similar to other columns without performing further steps.

Thanks
Satyaprakash J

Linq data source hierarchy in radGrid

Are there any examples of using a LINQ data source (or Linq2SQL in code) to create a hierarchy in a RadGrid? All the examples I have found use DataSets.

I have, for example, a User object that has Roles that are loaded with the Object. User.Roles returns a IEnumerable list of roles that that user belongs to.

Table Structure

User <- User Roles -> Roles

Thanks,

Brian

Multiple language support for grids

I'm looking for an easy way to loop thru and address all texts in a grid to create multiple language support by fetching texts in users language from DB:
- AddNewRecordText in CommandItemSettings
- CancelText, UpdateText and InsertText in EditColumn
- EditText in GridEditCommandColumn
and HeaderText in all columns.

For all other controls on the page, I loop thru the controls like this:
    protected void Page_PreRender(object sender, EventArgs e)
    {
        foreach (Control ctrl in Page.Controls)
        {
            findCtrl(ctrl);
        }
    }

    protected void FormView_DataBound(object sender, EventArgs e)
    {
        foreach (Control ctrl in FormView.Controls)
        {
            findCtrl(ctrl);
        }
    }

    public void findCtrl(Control ctrlTry)
    {
        if (ctrlTry.HasControls()) // if the control contrains other controls
        {
            if (ctrlTry.ID != null && ctrlTry.ID != "") // control has a ID-name
            {
                Response.Write(ctrlTry.ID + "<BR>");
            }

            foreach (Control lastCtrl in ctrlTry.Controls)
            {
                findCtrl(lastCtrl);
            }
        }
        else
        {
            if (ctrlTry.ID != null && ctrlTry.ID != "")
            {
                Response.Write(ctrlTry.ID + "<BR>");

            }
        }
    }
and use the controls ID to fetch the text from the DB.
But this approach doesn't work on texts in a grid.

Any ideas for multiple language support in grids using lookup i DB?

Axis Item Label Size

Hi,

I have a really small-sized chart (line graph) and I set the font size for the axis item label to 6.(Times New Roman).
However, it seems that it becomes too blur(because radchart is an image).
Rotating the labels did not help either.

My solution is to skip alternate axis item labels but this did not really work out as each axis item label cannot use the space left behind by an adjacent axis item label. A font-size 8 label will still wrap to the next line(which is not what i want) instead of "overflowing".

Does anybody has any idea on how to solve this?
Thanks a lot!!!

Panel Bar Auto-collapsed on load

Hello, I would like the Panel Bar to be auto-collapsed, so it does not display sub pages and I can't determine how to do this. Can you please help me?

For example, the panel bar on the home page of the following site I'm building shows the sub and sub-sub navigation. I only want it to show the home page and the top level navigtion which shows in the main navigation atop the site.
