Applying Filter

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?

Scrollbar width on DropDownList

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?

RadGridLocalizationProvider : custom GroupingPanelDefaultMessage

I want to give each of my grids a custom GroupingPanelDefaultMessage based on which column(s) is/are groupable. For example,

"To show sales grouped by Division, drag that column-header here".

I hope it is not necessary to create a custom LocalizationProvider for each such customization. Is it? If so, the following doc doesn't provide enough info:

http://www.telerik.com/help/winforms/gridview-localization.html

I don't see an object called RadGridLocalizationProvider anywhere. 
Is the RadGridLocalizationProvider an  object encapsulated by the grid?

Thanks

Moving the splitter programmatically

hi,

How can i move the spliiter programmatically? what i like to do is to mimic the behavior of the splitter in your examples. I intend to add a button to the panel and change the position of the splitter. I have tried to use the collapse property, but it also hides the button. therefore i need to change the splitter position my self and leave a little space for the toggle button.

I have also tried to use the prev and next buttons on the splitter, by they are hidden as well when the panel is collapsed.

Thanks,

Sharon.

Access only filtered rows in grid

How do I access only the filtered rows in a grid. I basically need to select the first row that is visible after setting a filter. I also have other needs for accessing only the rows that are still visible after a filter, but this is my first need.

NullReferenceException clicking on RadGridView empty area

Grid just populated with few rows, so there is an empty area below those rows.

Multiselection is enabled.

Grid has just been populated, so there are no selected rows.

If I click on the empty area below the rows, I get this exception:

System.Exception: Exception caught by

CurrentDomain.UnhandledException - type: System.NullReferenceException value:

System.NullReferenceException: Object reference not set to an instance of an

object. at

Telerik.WinControls.UI.GridRowBehavior.DoMultiFullRowSelect(GridCellElement

if I select a row, before clicking on the empty area, nothing happens.

I could preselect a row, just after populating. but I'd like to understand why this happens

Copy appearance of one cell to another

Hi dear Telerik team.

I have a VirtualGrid.

I have made workaround to substitute indent cell of a row with a text, lets call it "row header".

And I would like to know how can I deal to make "row header" looks absolutely the same as "column header" by the easiest way?

Please find attachment bellow.

Much thanks!

It should navigate the cell

When I click the tab on the last cell while it is in edit on the grid view, it should not navigate anywhere instead it should stay on the same cell (last cell) for editing.
Currently, when I click on the Tab button it moves to the next control or moves to the next row in the gridlines.
