In the screen capture below I have a RadGridView in a RadCollapsiblePanel. I need to hide the border for both the CollapsiblePanel and the PanelContainer. 

I tried the code below - which I found on another form post = but to no avail:

radCollapsiblePanel1.ControlsContainer.PanelContainer.BorderStyle = System.Windows.Forms.BorderStyle.None;                   radCollapsiblePanel1.ControlsContainer.PanelElement.Border.Visibility = ElementVisibility.Collapsed;

What am I doing wrong?

Thanks

Carl

I have a completely new winforms project. The only thing I adjusted was to change the target framework from .NET6 to .NET7 in the projects properties.

Now, each time I minimize (or maximize) a RadForm and then "normalize" it again, it is getting larger (some pixels to the right and to the bottom). This does not happen on .NET6 but on .NET7 and .NET8.

There is also an issue within the VS designer: When I open the form again its size is also slightly different (e.g. set to "300; 300" changed to "318; 243"). It also does not matter if I change the forms AutoScale value to "None", "Font", "DPI" or "Inherit".  Furthermore, I have no strange scaling in MS Windows, it is set to 100 %.

What is the reason for this behaviour and what do I need to do to prevent it?

I would also like you to check if this occurs to other controls, as well.

Hi,

Is it possible to modify mp4 output settings to increase video quality?

Currently it seems to be fixed at around 4 mbps which results in poor quality for full hd.

 

Thanks

Arturo

Is there a way to detect when the user clicks on the column header to sort.

An event like SortStarted and SortFinished?

I'd like to capture that event to perform some special processing.

I have a list of people in a datatable that I bind to a RadCheckedDropDown list via a bindingsource. This control is sited on the first page of a tab control. It's a list that provides the app user with a definable selection of staff members for a report.
On initialization of the form, only one item is selected, but as a test I check all items in the dropdown then move to the 2nd page of the tab control. If I then return to the first tab, the checkeddropdown list has returned to displaying only the initial single checked item .

I placed a breakpoint in my code and the dataset hasn't changed, ie the "Include" field still remains set to false for all rows except that initial row. ie checking items in the list aren't being reflected in the dataset. See untitled2.png

Have I failed to do something ?


      // 
      // CmbStaffFilter
      // 
      this.CmbStaffFilter.CheckedMember = "Include";
      this.CmbStaffFilter.DataSource = this.bsStaffFilter;
      this.CmbStaffFilter.DisplayMember = "Fullname";
      this.CmbStaffFilter.ItemHeight = 32;
      this.CmbStaffFilter.Location = new System.Drawing.Point(29, 35);
      this.CmbStaffFilter.Name = "CmbStaffFilter";
      this.CmbStaffFilter.ShowCheckAllItems = true;
      this.CmbStaffFilter.Size = new System.Drawing.Size(444, 20);
      this.CmbStaffFilter.TabIndex = 121;
      this.CmbStaffFilter.ValueMember = "RecId";

      // 
      // bsStaffFilter
      // 
      this.bsStaffFilter.DataSource = typeof(pulse.move.datasources.dsFilterStaff.dtFilterStaffDataTable);

Hi,

 

I used to do custom cells by adding controls through "createChildElements" methods, but it was really slow when having multiple columns and row displayed.

So I tried to use graphics only and I did everything in "PaintContent" methods. This is way faster, very smooth, but I sometimes have an error (very randomly) on bounds object (of radshaped form) being lock by another thread.

I wanted to know if this workaround for painting cells approved or not?

If not what/where would you recommand to do this?

Thanks in advance!

 

Simon

I am using an old version of RadGridView and from what I see the property EnableHeaderCheckBox properties not exist.

If there are any properties in an older version that I can use to implement select all by selecting column header.

Hi all,

How do you modify (or prevent) the display default "no data to display" text in when no line or column is yet set up ?

All forum answers are very old an do not work anymore, nor gridview.ShowNoDataText = false;

Thanks

Patrick
