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

[Solved] 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

[Solved] Suppress/Disable Cut/Copy/Paste Context Menu

We are having an issue with displaying only our custom context menu (do not want to show cut/copy/paste context menu) when the DropDownStyle is DropDown. When the DropDownStyle is DropDownList then the context menu works as expected.

On a right-click (or Apps key press: Keys.Apps) the cut/copy/paste context menu is shown for the editor textbox. We were able to work around not showing the context menu for the mouse right-click action by absorbing the MouseDown event of the TextBox (

radDropDownList.DropDownListElement.TextBox.MouseDown += radDropDownListTextBox_MouseDown

) and then displaying our custom context menu. We attempted to do a similar workaround by subscribing to the KeyDown event of the textbox editor component of the RadDropDownList, but we are unable to suppress the context menu.

Is there a way (or workaround) for suppressing the cut/copy/paste context menu that is shown for the RadDropDownList textbox editor component (especially for the Apps key press)?

Thank you for any help and information you can provide.

Scrool Bar on X-Axis

hi,

I have drawn a graph with Date on X-Axis. The width of the chart is 400px only.
whenever I am displaying the chart with 10 days data, it is displaying as required.
But when displaying the chart with 100 days data, the chart becomes more condensed so as to show all 100 days data within 400px.

My requirement is to display a scroll bar on X-axis, when ever the data is more than the 10 days(Approximately).
Note: Y-axis should be constant. (i.e whenever i am scrolling, Y-axis should appear, only the X-axis data needs to scroll).

Thanks and Regards,
chandra.

[Solved] Three problems with adding new row.

Hi
Version: 2010 Q2 SP2

1. When grid has at least one real row in row for adding new rows there is text:
    “Click here to add new row”.
    Problem is when grid is empty and there is only row for adding new rows.
    Then this row is selected and there is no text “Click here to add new row”.
    It might be confusing to the user – user might not know how to add new row.

How can I display text “Click here to add new row” in row for adding new rows if grid is empty (there are no real rows)?

2. If during adding new row user presses Esc button adding is canceled and text “Click here to add new row” is displaying – this is ok.
How can I know that user canceled adding new row? Is there any event for this?

3. Can I use some another text than “Click here to add new row”?
I would like to define my own text for adding new rows.

Regards.
