We have custom columns in our gridviews as one below. When exporting to Excel, the key values are exported instead of displays values.

Is there a way to export the value of DisplayMemeberPath (ProjId) instead of the DataMemeberBinding( ProjectRecId)?

 

Thanks,

I have a RadGridView and I've used the article located at: http://docs.telerik.com/devtools/wpf/controls/radgridview/style-selectors/rowstyleselector for styling the row Foreground color. Everything works great except the Alternate Rows have the same color as the "regular" (non-alternate) rows.

I use the "BasedOn" attribute of the style to use the loaded theme (expression_dark) and I thought I would create a second style just for the alternate rows. 

Here is the style code:

Then, in the RadGridView, I set these two options:

However, I get a run-time error when the xaml is parse on the "GridViewAlternateRowStyle" in the BasedOn attribute. Is there a different StaticResource I should be using? Thank you.

 

Dear Devexpress,

We are using your Gridview for WPF version 2015.1.225.40.

We have a problem :

for all columns we have a CellTemplate and a CellEditTemplate. The CellTemplate  displays a value(sum) and is always read only.

The CellEditTemplate contains 2 textboxes were 2 separate values can be entered.
When those 2 Textboxes in the CellEditTemplate are read-only, there is still a way to enter a value., Why ?

How is it possible ? By selecting a column by mouse. Just one click on it.( It may not go in CellEditTemplate ). Then press a key (fe 2). Result => the readonly textbox contains now a 2 !

This may not happen.

Is there a solution to fix this problem ?

I have put the exemple code in a attached file. When the CanEdit1 property is set to false the problem occurs.

regards,
Gert

 

 

 

Hi,

  I want similar editor as RadBrowseEditor in WPF where I can default path to open while opening the file dialog.Is there any similar editor in WPF controls or Is there any alternative??

Nagasree.

I'm trying to override or remove the ability to click directly on the content of a DesktopAlert. My problem is that when you set the alert's content to a plain string, it acts as a link-button and upon clicking the text, it will close the window. This is a problem since there are certain DesktopAlerts that I don't want to be closed at all. I can set it as Enabled = False but then the dropdown menu and other parts of the alert quit functioning. This is all created from code behind so it is a little harder for me to set any properties or templates for it in XAML. I thought perhaps I should post in this forum and see if there is a way to not only remove the ability to click the content, but also to remove/override events in code-behind in general for WPF controls created server-side.

Hi to all,

I would using ComboBox in specific behavior:

I populate ItemSource with List<MyModel>, OK.

I have to use IsEditable, IsFilteringEnabled, TextSearchMode that allow me to search through items.

When I want to select an item, I click on it. (Selection item not must be automatic)

After that I'll clear selecteditem.

Can I do it?

I tryed with MouseLeftButtonDown  event but it doesn't fire.

I want the QRCode size to match the Width & Height I specify on the control, but this doesn't work.
The size of the QRCode seems to be limited by Width & Height, but only changes when I set the Version differently.

I have tried to set the content alignment to Stretch also to no effect.

Can you please tell me how to do this?

Thanks,
 Alan

I have a RadCartesianChart with a DateTimeContinuousAxis. 

Is it possible to specify a zoom level based on a timespan? 

So that I only see 10 minutes of the chart - even when adding more data. And off course being able to pan through the rest of the chart.
