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

Is there a quick was to find out if something has changed in the contents of a sheet?

Ideally, I would like an event 'Something Changed in Sheet', which I can use to, for example, highlight a 'save' control.

Really slow way would be to keep the contents of all cells, paint them, then respond, for each cell, to an event, compare the 'was' and 'is' values, and generate another event if they are different.

Before I do this, I'd just like to check that there isn't a simple way which I can't find.

Thanks

I have 2 grids with drag and drop capability, one of them is just a simple grid with 2 columns, the other grid is a grid with 3 Hierarchical Templates that have 3 associated BindingSources.

How can I, when dragging and dropping from the simple grid to the hierarchical grid, determine which Template I am dragging the row to and add it to that Template/BindingSources?

I used exactly the example code you have here (https://docs.telerik.com/devtools/winforms/controls/gridview/rows/drag-and-drop), and indeed everything works.

I just wanted to understand if it's possible to know which Template the row is being dragged to and add it exactly to that Template.

I have a custom RadForm class that has inherited over a hundred forms. I have a custom RadTextBox class where I added some validation fired on the LostFocus event. To replace all RadTextBox controls with custom ones are a thousand controls to update, which are not an option.
I am looking for a way to maybe use events on my custom Radform which I can fire on Radtextbox control, it may be a way to update Radtextbox control to a custom one. Maybe other ideas on how I can use custom RadTextBox  control without updating one by one
