How do I determine if the scroll bar is showing?

I wrote my own code for handling resizing so that I could get the resizing functionality that I want. It all works fine ... until I display a scroll bar. Then the size is too large.

I thought "easy enough", I will just add a check for a scroll bar and make my widths shorter. From reading, it sounded like I should use VScroll to check that. However, this value is *always* false, even when the scroll bar is showing.

Is there a way my code can know that the scroll bar is showing so I can resize my columns appropriately?

Thanks!

Multiple controls in a cell

Hello,

I've done this in an ASP.NET application, now I need to do it in a WinForms application. I've attached an image of the web page that illustrates what I need to do. I need to programmatically create columns that contain a checkbox and a textbox. So it's really two issues, but the programmatic creation of columns is not really an issue as I've already done this. But since I don't know the columns at design time, I need to bind the grid to a DataTable I populate in code, rather than define them in design mode. However I need each cell to contain two controls, that are both live. When the user interacts with either control I need to highlight the cell to indicate that it has been modified. Really the only thing I think I could use an example for is two controls in a cell. See the attached image.

Thanks, Steve

ShowItemToolTips?

What is ShowItemTooltips supposed to do? I turned it on for my bound grid and don't see any tooltips.

What I was hoping for was to see the full text of each cell as I hover over the cell.

Is there a way to do this automatically? Or do I have to write the code to display cell tooltips?

Thanks!

Manual edit of year clears DateTimePicker

Have just upgraded to 2010 Q2 SP2 and found that when manually entering or editing of a date, that when you get to the year portion the control just clears everything and goes back to 01/01/1900 in the drop down portion. Confirmed that this occurs in the demo app as well. This is a critical problem as the drop down picker is not very useful when you have to enter historical dates like birthdays etc.

Restore original layout settings

I have a RadGridView that would allow the user to persist layout settings via the SaveLayout() and LoadLayout() methods. Is there a way in which the user can clear all the layout settings applied... something equivalent to a radgridview.ClearLayout() perhaps?

Display time result in RadChart

Hi,

I want to display times in my radchart ( horyzontal Bar type ) in format mm:ss:ff.
I use XML file to bind my radchart datasource :

<?xml version="1.0" encoding="utf-8" ?>
<items>
<item Title="encoding" val="12000" />
<item Title="writing" val="20000" />
</items>

my "val" is in millisecond.

but when I do

    this.DataSource ="myxml.xml";
    this.PlotArea.YAxis.Appearance.ValueFormat = ChartValueFormat.ShortDate;
    this.PlotArea.YAxis.Appearance.CustomFormat = "mm:ss:ff";

I can see on my chart "00:00:00" several times in my XAxis and data (val) is not converted.

What can I do ?

Thanks,

YSP

Checkbox headers duplicated on horizontal scroll

Hi,

I have a winforms radgridview on a form with it's dockstyle set to Fill so that i can scroll horizontally to see all the columns.

I am using custom checkbox columns with a 'select all' checkbox in the header as described in the knowledge base article here: http://www.telerik.com/support/kb/winforms/gridview/add-check-uncheck-all-check-box-in-the-header-cell.aspx

Now, if i drag the resize handle on the right hand edge of the form back and forth to resize the form, the header checkboxes shift around and sometimes get duplicated.

I have attached screen shots to demostrate.

Does anyone have any idea why this is happening and how to fix it ?

Thanks,
Matt
