Hi,

I am using scale breaks for my bar chart and I am wondering how to adjust the value at which the scale break occurs. There is a property - valueTolerance but it accepts a BYTE value and I am not sure how to use it. Or is there a way I could do specific customizations using the axisSegment property?

Can anybody help?

Thanks,
wayne

[Solved] filter dropdownlist on edit item

I have two columns in a radgrid.

Column1 = Client
Column2 = Category

The catgory column is related to employees. When I select edit item on the grid i need my category dropdownlist to only show categories for that client. And if I switch the client in edit item mode i need the category drop down list to update to reflect the new categories.

Thanks,

Jon

Reordering multiple items via drag/drop gives incorrect results

When I enable reordering in a list box as well as multiple-select, the control doesn't reorder the items properly. Example:
Initial List:
Text     SortID
A            1
B            2
C            3
D            4
E            5

If you select C, D & E and drag them between A&B, you should get a list sorted like A C D E B. However, here's what you get:
Text    SortID
A            2
B            3
C            4
D            5
E            3

Which results in an order of A E B C D (it effectively only moves the last item you selected). Actually, it is not even predictible since sortID 3 is duplicated.

This looks very much like a bug - is there a workaround or a fix available?

$find("<%=RadTabStrip.ClientID %>") is returning NULL

I have a web control with a RadTabStrip, and when I call $find(), I'm getting NULL. I know I must be doing something wrong, but for the life of me I don't know what. Currently, I have both the RadTabStrip markup and the javascript that is calling $find() in the same .ascx file, and it's still not working.

Any ideas where I am going wrong?

Formating GroupByHeaders for exporting to PDF

Hi guys,

I have been asked to output the RadGrid content to a PDF. I have used the following formatting code to do the formatting when the item is being created.
Note: that the Grid uses GroupBy headings (in which I am having trouble formatting)

Protected Sub RadGrid_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles rgResults.ItemDataBound

        If (TypeOf e.Item Is GridDataItem OrElse TypeOf e.Item Is GridHeaderItem) Then

            'to align the field left in the PDF even tho it looks ok on the webpage

            For Each cell As TableCell In e.Item.Cells

                cell.Style("text-align") = "left"

            Next

            Select Case e.Item.ItemType 'Mimic RadGrid appearance for the exported PDF file

                Case GridItemType.Item

                    e.Item.Style("background-color") = "#E8E8E8"

                    Exit Select

                Case GridItemType.AlternatingItem

                    e.Item.Style("background-color") = "#FFFFFF"

                    Exit Select

                Case GridItemType.GroupHeader

                    e.Item.Style("background-color") = "#000000"

                    e.Item.Style("color") = "#FFFFFF "

                    Exit Select

                Case GridItemType.Header

                    e.Item.Style("background-color") = "#000000"

                    e.Item.Style("color") = "#FFFFFF"

                    Exit Select

            End Select

        End If

    End Sub

Im assuming that the following code will format the groupby headings in the table however in the PDF it is in plain black text and not with a black background and white text:

                Case GridItemType.GroupHeader
                    e.Item.Style("background-color") = "#000000"
                    e.Item.Style("color") = "#FFFFFF "
                    Exit Select

Any comments will be grateful,

Thanks

RadGrid moving on AJAX postback

Hey all, I have a very interesting thing happening with my code and I'm hoping someone can at least point me in the right direction of a solution.

I have a page with a RadAjaxManager, a RadTabStrip that is associated with a RadMultiPage control. Inside one of the RadPageView controls of the RadMultiPage control is a UserControl that I have created. In that UserControl I have a RadAjaxManagerProxy (to communicate with the RadAjaxManager on the page), and a RadGrid. The problem I'm having is that whenever there is an Ajax postback from any of the buttons or drop down lists in the UserControl, when the postback is completed, the RadGrid is somehow rendered in a different place. It's being put at the end of the RadMultiPageControl, after all of the <div>s of the RadPageView controls.

If I didn't explain that well enough, let me know and I'll try again.

Is there anything special I need to know about having a RadGrid in a UserControl, or using a RadAjaxManagerProxy in a UserControl? I'm really at a loss as to why this control is seemingly jumping to this new position (outside of it's parent control) upon Ajax postback.
