Can the behaviour of column header cell be changed to the following one?

When there is no space to display the whole header text, the text shall be wrapped so that it spreads over 2 (or more) lines.

(Initially now the text is cut off and 3 dots are added at the end.)

Hi.

I have a RadGridView object named rgvLinkList that contains a GridViewCommandColumn. I use a table that is read from an Access database as the data source (but I don't show all the columns in the database in the grid, I hide some). Then I add a command column to the grid, and take the button text in each row from another column (one of the hidden columns) in the grid.

My problem is: I want to add a filter to the command column, I tried to do something similar to the one described at the address below but failed.
https://www.telerik.com/forums/filtering-on-a-command-column#ZuNrDBneqEmAi9qmv8ZXtQ

The method I use for setting data source, adding command column and hiding some columns:

Add column method:

CustomCommandColumn class:

CellFormatting event of my RadGridView : 

CellBeginEditevent of my RadGridView, The descs array here consists of text values (text above buttons) read from a column in the database (Similar to Emanuel Varga's example) :

And EditorRequired event of my RadGridView  (Again, similar to the example of Emanuel Varga) :

I was able to add a filter to the column after all, but when I type something in the filter text box nothing happens. I wonder what is missing or wrong?

Hi Team,
         We are using the windows application (vb.net). In our project, we need to hide one of the header text columns (Price) in the RadGridView dynamically. We are setting the condition to hide and show the HeaderText. If the value is "0" the Headertext (Price) should be hidden. If the value is 1 it should be visible. Can you please help with it. Screenshot mentioned below for your reference.

I have a RadGridView with several columns: 1st is a checkbox, 2,3,4 contain some strings.

If I want to select a checkbox and I click on the first column, the CellClick event is fired but there's something I don't understand.

When the first CellClick event is fired, the Checkbox does not get activated. When I click again on the checkbox, only then it is activated but for some reason it goes out of sync with my code. When the UI shows it is activated, the code says that nothing is selected and viceversa.

How should I properly do a selection of multiple checkboxes which trigger from the first click?

While I have been a heavy user of the Asp.net/Ajax suite of Telerik controls, I have never actually deployed any winforms based apps before.  I took an existing legacy production application, stripped it of Crystal Reports, added a RadGridView control along with a couple of RadButtons.  Everything works marvelously in a development mode. When it comes time to publish the application it appears to be impossible to publish it and install the resulting installation.

I have used all the suggestions I have found, such as resetting the "Application Files" on the publish page.  Everything seems to be properly configured yet the application remains un-installable once published.  I get "the manifest may not be valid or the file could not be opened errors".  The "invalid child element 'SignedInfo' is found.  I have dug into the installation folder and see the relevant files are in place.

Now I hesitate to point fingers to Telerik however the second I rollback to my pre-Telerik state I can publish the same app, using the identical settings, and properly install the application.  This suggests, to me, that I am somehow failing to include something.  Can anyone please assist or point me to help?

Am I missing some magic?

Hello,

I tried to remove the text indent of RadLabel but i couldn't.

Should I make the RadLabel's text have no any indents?

As in the attachment, I already set the margin and padding to 0

Please help me

Thanks,

how do all this syntax in GVMCCB ?

I'd like to add and show an Bitmap from Resources to Grid Column. But it doesn't work.

Is there any very simple example?

Gridview.Rows[count - 1].Cells[header].Value = new Bitmap(Resources.test);
