Is there an event like this in the Spreadsheet control?

What I need is when the user selects a single column, I enable/disable various menu options, but I can't find an event which is fired when a column in a sheet gets selected.

(BTW - I got the name of this event from ChatGPT, which thinks that a RadSpreadsheet has this event, but it's working from data up to 2021, so maybe this is an old event?)

Thanks

I need to show the user some XML, but formatted nicely (identing, colors etc).

Can I use RichTextEditor for this? If so how (vb.net please!).

I don't need to edit the XML now, but I will need to in future (hence not using a Browser-type control)

Thanks

I have a project where the user wants a multi tab control on a WinForm - no problem.

On the first tab however, they want too many controls to fit on the screen, Therefore they want the first tab's RadPageViewPage to scroll up and down. They do not want a sub tab. The problem is that there are so many controls that if they were separate tab they would fill four of them. I realize that scrolling is not the point of a tab control but this is what they want. Still, there are limits to the size of a Form and the size of the RadPageViewPage control.

Is this something that can realistically be done or is this just asking for too much?

Thanks

Hi,

I'm trying to display the check box in the header of a GridViewCheckBoxColumn and have it centered but it is still not aligned with the rest of the rows. 

I set the column property HeaderCheckBoxAlignment = ContentAlignment.MiddleCenter but still there is a gap. Please see the image attached.

Thank you,

Hi Telerik support team,

I've performance issues with sorting in a radGridView. Below you find a very simple example (grid with 2 text columns) and nothing specials. The dataset (deserialized from a json file) contains 7560 rows, which is not much. 

My own conclusion is 'it depends on the data'. In my dataset the column PhaseName is sorting ok. ProjectName is very slow. When I group the columns I see that ProjectName has not much groups (so a lot of duplicates) and PhaseName has a lot of groups (so, not much duplicates).

I tried to fasten it up with custom sorting but I got the same result. Can you help me with this issue??

(by the way: grouping also takes a lot of time)

Code:

    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();

            radGridView1.Columns.Add(new GridViewTextBoxColumn("ProjectName") { ReadOnly = true });
            radGridView1.Columns.Add(new GridViewTextBoxColumn("PhaseName") { ReadOnly = true });

            LoadData();
        }

        private void LoadData()
        {
            var json = File.ReadAllText(@"c:\Daniel\content.json");

            var list = JsonConvert.DeserializeObject<List<ProdTemp>>(json);
            radGridView1.DataSource = list;
        }

        internal class ProdTemp
        {
            public string ProjectName { get; set; }
            public string PhaseName { get; set; }
        }
    }

Hello,

I am trying to export a radPivotGrid into excel as per the documentation

 private void radButton1_Click(object sender, EventArgs e)
        {
            SaveFileDialog sf = new SaveFileDialog();
            sf.Filter = "EXCEL | .xls";
            if (sf.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
                // Telerik.WinControls.UI.Export.ExportToExcelML htmlexport = new Telerik.WinControls.UI.Export.ExportToExcelML(radPivotGrid_StockPositionPivot);
                //  htmlexport.RunExport(sf.FileName);


                PivotGridSpreadExport spreadExport = new PivotGridSpreadExport(radPivotGrid_StockPositionPivot);
                spreadExport.RunExport(@"..\..\exported-file.xlsx", new SpreadExportRenderer());
            }
        }

the red marked position is throwing an exception, and code suggestion is asking to create a new class to implement SpreadExortRenderer I am not sure how it can be done, any help will be appreciated. TIA

Please see the picture attached - I 'd like to display only the green options,

thank you

Dear sir/madam,

I used your solution for adding a checkbox in grouprows of a grid for UI Winforms:

winforms-sdk/GridView/GridCheckAllGroupRows at master · telerik/winforms-sdk · GitHub

Only specific grouprows need a checkbox, not all grouprows, which I handle in the CreateCell event. So far so good, seems to work perfect.

But.... when I start scrolling in the grid, because not all grouprows are visible in one screen, and the grouprows that have a checkbox leave the screen because of scrolling down, and then scrolling up again, the checkbox in the grouprow is gone, and grouprows that did not have the checkbox have now a checkbox?

Strange, I cannot figure out what is going wrong.

Hopefully  I succeeded in describing the situation clearly.
Help would be appreciated.

Kind regards.

Hi,

I have a radgridview with fullrowselect enabled. When i select a cell, the row is selected correctly, but the selected cell changes padding or width slightly which seems to affect the entire column.

It's just a minor visual annoyance, but is there a way to prevent this?

Thanks,

Philip
