For example we have RadGridView with 5 columns : column1, column2, column3, column4, column5

column2 and column5 are set to readonly

normally tabbing skips readonly columns, so when user hits Tab focus goes column1->column3->column4->New Row

        private void radGridView1_CellValidating(object sender, CellValidatingEventArgs e)
        {
            if(e.Row is null) return;
            if(e.Column.Name == "column3")
            {
                if (true) // some condition that fires based on entered value
                {
                    e.Row.Cells["column4"].ReadOnly = true;
                }
            }
        }

Hi,

I have a pivotgrid table like this:

true  |  vegetables    |   data   |  data  |  data
         |  fruit                |   data   |  data  |  data
         |  subtotal         |   data   |  data  |  data
----------------------------------------------------
false  | vegetables    |   data   |  data  |  data
          | fruit                |   data   |  data  |  data
          | subtotal         |   data   |  data  |  data 
How can i change the row header (true, false that are boolean values) using specifically cellformating?

Hi ,

I have one issue for pageviewpage inside radgridview. Almost ppl can see pageviewpage inside radgridview all of column in attached file (pic1) but one pc only can't see the last column in attached file pic2. Actually, she can see before I download telerik dll in dec 2022. After I used the latest version of telerik , she can't see the last column. We already formatted pc but still issue. May I know why these issue happen?

Hello!

There is a little trouble while exporting Telerik RadGridView Rows to PDF or Spreadsheet. The problem with this code is down below.

GridViewSpreadExport gridViewSpreadStreamExport = new GridViewSpreadExport(this.gvList);
gridViewSpreadStreamExport.RunExport(filename,  ?)

Is there a Desktop equivalent example of this example?

https://demos.telerik.com/aspnet-ajax/listbox/examples/applicationscenarios/treeviewdraganddrop/defaultcs.aspx

I'm struggling to figure out the way to handle this. I have a treeview showing a list of accounts, and a treeview that allows for grouping these accounts in a hierarchy. Both have underlying classes that are populated from a database.

I'd like to allow my front-end users to drag and drop accounts from the listView to the treeView. The one attribute they have in common is an AccountNumber. All other attributes in the Hierarchy can be derived from other controls on the form. 

I read about adding a DataConverter, but cannot figure out how to implement this. For example, on this page: https://docs.telerik.com/devtools/wpf/controls/dragdropmanager/behaviors/listboxdragdropbehavior
it has a reference to DataConverter (but the definition for that seems to lack). 

The other references I've seen is to a DragDropManager, but I don't seem to be able to find concrete examples for Desktop for that, either.

Googling so far hasn't really helped.

Any assistance would be greatly appreciated!

Hi.

I have a problem for GridView SearchRow. 

All text in my grid is capitalized. However, when I type in lowercase in the search box, there is a problem with non-English characters. I want lowercase "i" to change to uppercase "İ", but the search doesn't work properly because it turns into uppercase "I".

Thank you in advance for your help
