I have a reasonably complex request for the GridView control, is it possible to group some rows but not others? and also to have it ordered so i have some of my ungrouped rows above and some below the grouped items?

i have a fixed number of rows... it'll look something like this .. (each row has 3 sets of checkboxes after the below text).

- create (ungrouped)
- Review (Group Header)
        - Send for Review
        - Fail Review
        - Pass Review
        - Cancel Review
- Approval (Group Header)
        - Send for Approval
        - Fail Approval
        - Pass Approval
        - Cancel Approval
        - Bypass Approval
- Delete (ungrouped)
- Withdrawn (ungrouped)
- Review (ungrouped)

Hope that is clear to you.

Cheers :)

Exception in menuItemBestFit_Click(Object sender, EventArgs e)

Hi,

I am using Rad Grid View of telerik version 8.2.0.0.
Sometimes I get an exception if I call 'best fit' on last column via context menu. It is not reproducible every time and here is complete log

System.NullReferenceException:

Can I handle this issue at my end? Please let me know.

Grouping Issue - Group Header Text Disappears

This issue, as far as I can see, is totally GUI based. I don't think you need any code to re-create it.

When there is a column (or two) in the "group by" panel, and you hold and slightly move one of the columns, but not enough to actually change the grouping, one of the group header's text will be cleared. In my case I have used the AutoGenerateColumns feature along with SaveLayout and LoadLayout. I am on Windows Vista. Even in this example application (for a different thing), the issue is still shown.

RadGridview Getting the SelectedRow

Hi,

I am struggling to find an equivalent event to the generic gridview selectedrow.

I'm currently using the fowwing code, but i feel there must be a more appropriate way of completing this task.

int selectedindex = gvOffSite.Rows.IndexOf((GridViewDataRowInfo)gvOffSite.CurrentRow);

SelectedID = (

int)gvOffSite.Rows[selectedindex].Cells["EntityID"].Value;

In brief i want to use data from the radgridview selected row, something similar to this i hope;

this.radgridview1.selectedrow.cell[i].value.... etc etc

Can anyone help please?
Regards
Chris

Fancier ToolTips

I have just implemented my first RadTooltip using ToolTipTextNeeded and was wondering whether it would be possible to send something more sophisticated back such as (X)HTML which would allow users to format the tooltip text in a more sophisticated manner. You could therefore create your own bold text, italics, paragraphs etc. and if you wanted to get really fancy, you could consider allowing users to embed graphics in the tooltip too.

Just a suggestion.

Best regards

Marek

Problem with autohide and controls

I have a form with one docking manager, I have defined 2 autohide panels on the left and 4 autohide panels on the right. I have 3 panels docked in the center of the form.

I have added a radgrid to one of the authide panels. when I run the application and hover over the panel tab it opens, but the grid does not show. If i dock that panel the grid then shows.

How can I make the controls inside of a panel show when the panel is opened up with the mouse hovering over it.
