Is there a way to highlight the border of the currently selected thumbnail on the pdf viewer?

I simply want my users to know which thumbnail they've clicked on (which page they are on) since a lot of the documents they view look the same from page to page.

Thanks.

I am using the rad multi combox box and it work rather well on touch I just want to make the blue area wider so it looks like they touch it with their thumb its very small at present and easy for them to miss.

Hello,

There are images with background themes.
I need to implement a dropdownlist with images only.
All images have the same size 150x50, so when I press the down button it should show the full item list. Those may be elements of an imageList.
I tried Telerik RadDropBownButton, and RadButtons as items.

The attached picture is what I have now. As I can see the left is the position and place for the image, and there is still small place for text. There is no text, only image. How to hide the text place, to keep only image?

why the background-color remains the same although another line was selected.
this only applies if foreColor is changed.

                    if (Convert.ToDateTime(cell.Value.ToString()) != Convert.ToDateTime(e.Row.Cells[ColumnTitle.GridOperation.Liefertermin].Value.ToString())) {
                        cell.NumberOfColors = 1;
                        cell.DrawFill = true;
                        cell.ForeColor = ColorDeltaLieferterminAbteilungstermin.FColor;
                        cell.Font = new Font(DefaultFont, FontStyle.Bold);
                    } else {
                        cell.Image = null;
                        cell.DrawFill = false;
                        cell.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local);
                        cell.ResetValue(LightVisualElement.ForeColorProperty, ValueResetFlags.Local);
                        cell.ResetValue(LightVisualElement.NumberOfColorsProperty, ValueResetFlags.Local);
                        cell.ResetValue(LightVisualElement.BackColorProperty, ValueResetFlags.Local);
                    }

thanks andre

I've done some searching but was unable to find anything to help my specific case. I am using an AutoCompleteEditor class to enable drop down textboxes on my grid view, but I want to limit the token to 1 min and max. How can I do this? You may ask why I am using this instead of a ComboBoxColumn. The answer is: I have been instructed to not show any drop down arrows. 

Here is the class that I've taken from forums:

  class AutoCompleteEditor : RadTextBoxControlEditor
    {
        protected override Telerik.WinControls.RadElement CreateEditorElement()
        {
            return new RadAutoCompleteBoxElement();
        }

        public override void OnKeyDown(System.Windows.Forms.KeyEventArgs e)
        {
            RadAutoCompleteBoxElement element = this.EditorElement as RadAutoCompleteBoxElement;

            if (element.IsAutoCompleteDropDownOpen)
            {
                return;
            }

            base.OnKeyDown(e);
        }
    }

 

I am trying to validate data entered into the cell, but it looks like end users are able to select multiple values. I want to completely disable this ability and allow only a single value to be selected.

It would be much simpler to use a regular ComboBoxColumn, but I am unable to convince decision makers other wise.

Hi.

An exception is thrown when I reset my data source (first to null to clear it), but I dont know when it really happens. It happens very seldom but it does happen.

Object reference not set to an instance of an object.
   at Telerik.WinControls.UI.TableViewDefinitionBase.GetRowHeight(GridViewRowInfo rowInfo, IGridView gridView)
   at Telerik.WinControls.UI.GridTableBodyElement.GetRowHeight(GridRowElement row, Single y, SizeF availableSize)
   at Telerik.WinControls.UI.GridTableBodyElement.ArrangeOverride(SizeF finalSize)
   at Telerik.WinControls.RadElement.ArrangeCore(RectangleF finalRect)
   at Telerik.WinControls.RadElement.Arrange(RectangleF finalRect)
   at Telerik.WinControls.Layouts.ContextLayoutManager.UpdateLayout()
   at Telerik.WinControls.Layouts.ContextLayoutManager.UpdateLayoutCallback(ILayoutManager manager)

Thanks,

Hello everyone,

I've built an application using winforms (c++) and Telerik and when i run it from the computer i made it on, it works with no problems. However once i copy it over to my laptop, the .exe file simply won't run. No error messages, it just doesn't open. I have tried it on another computer and got the exact same problem.

I followed the guide here: https://docs.telerik.com/devtools/winforms/deployment-and-distribution/application-deployment

All the .dll files are in the same folder as the .exe and yet it still does not work. Has anyone had this problem before and would they be able to help me fix this please?

Thank you!

     I have a control RadMultiColumn Control on my form as you can see here its showing Telerik.WinControls.UI.GridViewDataRowInfo in the text box however when selecting the option it then throws a null statement.

            dpStockSelection.DataSource = _sageManager.ProductFetchAll();            

public List<Product> ProductFetchAll()
      {
 
          if (!IsConnected)
              throw new Exception("Not connected to Sage");
 
          List<Product> products = new List<Product>();
          SageDataObject230.IStockRecord sageStockRecord = (SageDataObject230.IStockRecord)_workSpace.CreateObject("StockRecord");
 
          try
          {
              if (sageStockRecord.MoveFirst())
              {
                  do
                  {
                      products.Add(CreateProduct(sageStockRecord));
 
                  } while (sageStockRecord.MoveNext());
              }
          }
          finally
          {
              sageStockRecord = null;
          }
 
          return products;
      }

I am using Q1 2008 Winforms.

There is radgridview named 'gv'. gv is filling with some manipulated data. I can filter by clicking and selecting some values. I want to filter wiht my own buttons. Basicially i created filter like this:(c#)

01.private void btFilter3_Click(object sender, EventArgs e)
02.{
03.    gridTest.EnableFiltering = true;
04.    this.gridTest.FilterDescriptors.Remove("IssueDate");
05.    FilterDescriptor filter = new FilterDescriptor();
06.    filter.PropertyName = "IssueDate";
07.    filter.Operator = FilterOperator.IsGreaterThan;
08.    filter.Value = DateTime.Now.AddMonths(-5);        
09.    filter.IsFilterEditor = true;
10.    this.gridTest.FilterDescriptors.Add(filter);
11.}

 

By clicking the button code is running. On Screen; the date value  (what i described above) is appearing on filter area. But data on the gv isn't filtering.

When i filter with another value(date) manually, gv is filtering. After that manually process when run code by clicking the button, code is running and data on the gv is filtering also.

I need filter without manually process. 

What am i missing?

Hi, we used to use Telerik version 2012. Sometimes we needed to have wider scrollbar on dropdownlist for example on touchscreens. Now in Telerik 2018 when we change scroll width in windows regedit all applications change their scroll width except this one with Telerik. How can we change scroll width now?
