I didn't want to hijack this other thread, but as it talks about performance it is related:
http://www.telerik.com/community/forums/thread/b311D-bbbmem.aspx

In that thread you state that you are reworking the gridview for better performance and we should see something in the next release (2008 Q1?).

For the most part the gridview performance isn't that bad in my project, but one area it is extremely poor is using the BestFit() method on a column. I like to present a stylish output to the user and with dynamic data drawn from the database it is pure guessing to set the columns to a defined width. So after assigning a datasource, I loop over the columns and call BestFit(). This is very slow. I've taken to only doing it to a few key columns, but it would be nice to have the whole grid formatted nicely.

I just wanted to make sure improving performance of this method was part of the plan for the reworking of this control.

I have a gridview bound to a BindingSource bound to a typed DataSet, with the member specified as one of my DataTables
.
I've updated the SQL for the dataset, but when I add columns to the gridview, I don't see those new columns in the DataField dropdown.  Even if I type in the name of the field to bind to, the column is empty.

What do I need to do?

Hello everyone,
            I want to add a TextBox in a particular chunk in my RibbonBar control. I read a post on how to add a TextBox to a RibbonBar but I couldn't add it to a particular chunk. Is there anyway to do that?
Thank you

Hi
What are the chances of getting a logarithmic X capability (as well as teh current Y implementation) and multiple Y axes (to show different ranges and scales)?

Best regards

Hello,

I've seen a few threads on being able to control the height of a dockpanel (or in our case a UserDockControl...we've set TdiContainerVisible to true, and then set the Size...but it is not working in Q3 version...??

Any ideas?

Thanks,
Gary

hi guys,

is it possible to customize the filter row according to the column-values?
for example: I have boolean-column, which the user is able to tick. I would like to have the same tick-box within the filter-row.

my datagrid uses a column with progressbars.
I apply a filter, the correct rows are shown. I delete the filter, all rows are shown again. BUT the progressbar doesnt show its value any more(no progress visible)
Does anybody know, how to get around this?

cheers

I've just gotten my hands on the Q3 release, and I'm looking through the demo application to check out what's new.

I noticed that the way the date picker handles dates isn't working very well. A couple things I noticed right away in the demo on the RadDateTimePicker page:

1. Long Date Format, if you change the year or day, the day text (Thursday, etc) doesn't change if you exit the control (tab away, or click on another control). However, if you click on the control again after leaving, the name of the day will change to be the correct one.

2. Probably linked to this, but worse: If you change the date on the short date format box, by typing in something like 2008.. and then click the drop down menu to get the calendar, the calendar refuses to update itself unless you click away, click back into the text area, and THEN click on the down area to display the calendar.

3. Time format.. O_O How on earth does picking a date have anything to do with the time format? You also can't tab to jump between hours / minutes / seconds, making it pretty much useless as a time control.

4. I can't seem to get the calendar to display a date from before 1900, although I suspect that may be a setting - at the very least though, it shouldn't allow me to actually enter a date not in the range of the calendar...

5. Heh. The tab order on the RadMaskedEditBox DateTime screen is out of order :)

For simplistic Microsoft treeview serialization, you can do:
        Dim aList As New ArrayList
        Dim fs As New FileStream("D:\temp\test.dat", FileMode.Create)
        Dim f As New BinaryFormatter
        For Each node As TreeNode In Me.TreeView1.Nodes
            aList.Add(node)
        Next
        f.Serialize(fs, aList)
        fs.Close()

I get an error attempting to serialize the RadTreeview control in a similar manner - telling me that the nodes collection is not serializable.
Is the Winforms or Asp.net treeview control serializable, or is there a work around?

Hello,

How can I disable the context menu

(the one with these items
-Close
-Close All But This
-New Horizontal Tab Group
-New Vertical Tab Group)

of my docking panels?

Thanks,

I keep getting the following error when I try to Load XML File in the demo for RadTreeview XML Serialization section:

Is there something that I am doing wrong? My xml looks like this:
