Change BackColor in RadDataEntry Validation Panel

Dear all,

does anyone know how to change the BackColor ofthe RadDataEntry ValidationPanel.

I have tried various ways like setting it up at design time in Visual Studio,

or just before showing it at run time

dataEntry.ValidationPanel.BackColor = Color.PapayaWhip;
dataEntry.ShowValidationPanel = true;

and also via some event such as

private void rdeDynamicInput_Initialized(object sender, EventArgs e)
{
ValidationPanel vpanel = (sender as RadDataEntry).ValidationPanel;
if(vpanel != null) vpanel.BackColor = Color.PapayaWhip;
}

Thanks for your answer

Vertical (rotated) text in TableCell

Hello,

I'd like to know if it is possible to insert rotated text into TableCell (like in the attached image - orange part of table).

I read many forums about this problem, found only one solution - https://www.telerik.com/forums/rotate-text-in-table-cell

The problem is, this custom class is implemented for Telerik.Windows libraries, I'm using Telerik.Winforms.

Thanks,

Martin.

Radtimepicker step 15 minutes not working properly

So I want the user to choose a time with an interval of 15 mins, I disabled key presses because their is no proper way to handle it to round up to the nearest 15 mins.

Anyways my issue is that I tried using this setup so that the user can easily pick 15 mins interval

      this.ReturnTimePicker.Step = 15;
      this.ReturnTimePicker.TimeTables = Telerik.WinControls.UI.TimeTables.HoursAndMinutesInOneTable;

The result looks like this

So ok, probably a bug or 15 mins is not supported because of how many the choices would be.

So now I decided just to use the 2 tables instead of 1.

  this.ReturnTimePicker.Step = 15;
  this.ReturnTimePicker.TimeTables = Telerik.WinControls.UI.TimeTables.HoursAndMinutesInTwoTables;

The result is

It technically works and it's great but as you can see the Minutes is hidden, I need to drag the popup so it opens up properly.

I don't want my users to do that every time, so I want the control to be already expanded fully

Any fixes or alternatives on this issues?

It's possible to create RadContextMenuManager programmatically ?

Hi ,

I need to create RadContextMenuManager programmatically in a "base" RadForm ( wich is inherited by other Forms Classes).

I don't want to add it with the designer.

It's possible?

If i add a property RadContextMenuManager, i cannot see this.RadContextMenu .

RadDropDownList gives message in debug output window when I click

Hello community!!!

Every time I click on a RadDropDownList I get this message into my debug output window:

The thread 0x588c has exited with code 0 (0x0).

The 0x588c changes every time.

Any idea why is this happening? Is this a normal behavior of RadDropDownList or something?

Thank you for your time!!!

Adding Rows to non-bound RadDataGridView performance

I'm populating the RadDataGridView via setting up the columns, then suppling an array of objects for each row I need to add. I can't use a bound grid as we need columns that are not actual values of the object (for example View/Edit buttons that then open the record for the user). I cannot run this in a virtual grid as we are using the grouping functionality to allow users to organize the data. Currently populating the grid takes over half the time of the process. Anyone have additional suggestion for things to try?

 public void AdvancedRowsPopulation(IList<object[]> rows, bool doReset = true)
        {
            var tmr = System.Diagnostics.Stopwatch.StartNew();
            radGridView1.BeginUpdate();
//Have to reset the columns so the object[] matches up again
            string settings = GetGridXml();
            SetGridToXML(BaseGridSettingsXML);
            DetachColumnListeners();
            tmr.Stop();
            Log.Info($"Grid to default took {tmr.ElapsedMilliseconds / 1000.0}s.");

            tmr = System.Diagnostics.Stopwatch.StartNew();
            if (doReset)
            {
                radGridView1.Rows.Clear();
                cachedRows = new List<object[]>();
                lastDataSet = new DataTable();
                foreach (var col in radGridView1.Columns) lastDataSet.Columns.Add(col.HeaderText);
            }
            for (int y=0;y<rows.Count;y++)
            {
                var row =rows[y];
                radGridView1.Rows.Add(row);
                lastDataSet.Rows.Add(row);
            }
            lblDataCount.Text = radGridView1.Rows.Count.ToString();
            tmr.Stop();
            Log.Info($"Grid Row Population took {tmr.ElapsedMilliseconds / 1000.0}s.");

            tmr = System.Diagnostics.Stopwatch.StartNew();
            BaseGridSettingsXML = GetGridXml();
//Set grid back to what the user had last seen
            SetGridToXML(settings);

            radGridView1.EndUpdate();
            tmr.Stop();
            Log.Info($"Grid to user's layout took {tmr.ElapsedMilliseconds / 1000.0}s.");
        }
