Using the expression editor in a gridview, I'm trying to determine how much time in minutes has passed between a column that only has time and NOW()

Column:  arrived_time (time)

something along the line of: DATEDIFFMINUTE(arrived_time, NOW()) >= 15

since arrived_time is time only, it seems to fail when compared to NOW().

Is there a way to add today()+arrived_time to get a proper datetime value?  

End goal is if more than 15 minutes has passed since arrived_time then change RowBackColor

Hi, 
       I want to drag and drop row in same grid like reorder the row. Is it possible to without create custom control ?
Actually we have file names in each row, user want to merge the file based on drag and drop, So user from which place to which place drop the row, we will merge that two file and refresh in grid. So for this we want drag and drop function.

I tried RadGridView.AllowRowReorder property to true , but still cant drag and drop the row. This is page load code for bind data in grid.

Hi folks.  There seems to be a lot of questions about this and every answer I could find pointed me at some web solution.  This is Winforms and nothing I've seen so far has been in line with my current issue - so here goes!

WinForms .Net 4.7.2 VB

A simple grid (See gridPIC.png)

3 Columns:

• Decimal DecimalPlaces = 0  FormatString = {0:N0}
• Decimal DecimalPlaces = 2  FormatString = {0:N2}
• Decimal DecimalPlaces = 4  FormatString = {0:N4}

Export property settings:

• HiddenColumnOption = HiddenOption.DoNotExport
• SummariesExportOption = SummariesOption.DoNotExport
• ExportVisualSettings = False
  

When using ExportFormat = SpreadStreamExportFormat.Csv you can see the integer shows 111, the 2 decimal data shows 222.22 and the four decimal data shows 333.3333 as expected. (See csvPIC.png)

But when using ExportFormat = SpreadStreamExportFormat.Xlsx the results are incorrect (*See ExcelPic.png)

I was expecting that the export file would include the format information.  I thought perhaps because I'd set spreadStreamExport.ExportVisualSettings = False that this was the cause but I can flip that to True and the output is identical.

The DATA that gets into Excel IS CORRECT.  It's just not formatting the cells as expected.

Is there any way for spreadStreamExport to output the proper Decimal formatting? 

If yes, can you point me at a sample?  C# is just fine if you folks aren't vb.net users.

Thank you all!

I have  abound gridview that i have added a checkbox column to as the first column.
i cannot check any checkboxes in any row, only able to check the headercheckbox which selects all checkboxes of every row.

Dim checkboxcolumn As New GridViewCheckBoxColumn
checkboxcolumn.DataType = GetType(Integer)
checkboxcolumn.Name = "SelectedColumn"
checkboxcolumn.FieldName = "Select"
checkboxcolumn.HeaderText = "Select?"
GV_Assets.MasterTemplate.Columns.Add(checkboxcolumn)
checkboxcolumn.EnableHeaderCheckBox = True

How to convert PDF pages to images in .NET Framework app? I've scoured the site, and it seems you recommend something like this:

RadPdfViewer pdfViewer = new RadPdfViewer();

pdfViewer.DocumentLoaded += (sender, e) =>
{
	if (sender is RadPdfViewerElement pdfViewerElement)
	{
		for (int i = 1; i <= pdfViewerElement.Document.Pages.Count; i++)
		{
			Image pageImage = pdfViewerElement.ExportPage(i, 1, true, ImageFormat.Jpeg);

			// Use pageImage
		}
	}
};

pdfViewer.LoadDocument(pdfPath);
pdfViewer.LoadElementTree();
Application.DoEvents();

Is this really the best way for .NET Framework apps? There is an example that uses PdfProcessing instead of PdfViewer, but requires the assembly Telerik.Documents.Fixed.FormatProviders.Image.Skia, which I don't have available in my Visual Studio with latest update of Telerik UI for WinForms 2024.3.806.462. Nor is it available on nuget, or I don't know how to find it.

Hi everyone,

I’m currently using RadRichTextEditor to print logs. I have the following scenario:

• The first line prints "Hello" in black font.
• The second line prints "world" in red font.

How can I change the font color for different lines in RadRichTextEditor?

Thank you!

Created a column like this:

if (operation == "viplata")
            {
                GridViewCheckBoxColumn checkBoxColumn = new GridViewCheckBoxColumn
                {
                    DataType = typeof(bool),
                    Name = "Выбрать",
                    FieldName = "Выбрать",
                    HeaderText = "Выбрать",
                    EditMode = EditMode.OnValueChange,
                    ReadOnly = false
                };
                checkBoxColumn.EnableHeaderCheckBox = true;
                radGridView1.MasterTemplate.Columns.Add(checkBoxColumn);
            }

The column is shown, but nothing can be selected. I have an event connected to DataGridView1_DoubleClick, so the checkboxes must be set by one click. How can I implement it?

I have grouping enabled in my grid.How can I make it so that when I press a key, only open checkBoxColumn groups are selected?Thanks for your help.

Hi, I am customizing the theme VisualStudio2022Light. I have changed the purple color to the teal. However, I am not able to change the background and selected row in the theme.

When I run my application, it is still in purple.

I found a similar issue where I couldn't find where I can change the close button during click in the RadForm.
