I might be missing something, but I have Hyperlinks in a column in my RadDatGridView.

 

I tried searching for a Support document explaining this, but didn't find any.

 

When the grid is exported to excel all data is coming across, but the column with hyperlink is not

a hyperlink in Excel.

 

Below is sample of the code used to make the "HyperLink" column in my grid.

                radGridView1.DataSource = dtResults;
                radGridView1.Columns.Remove("Path");
                GridViewHyperlinkColumn col = new GridViewHyperlinkColumn();
                radGridView1.Columns.Insert(5, col);
                col.Width = 200;
                col.FieldName = "Path";
                col.HeaderText = "Path";
                col.Name = "Path";

 

Coded used to do the Export....

               GridViewSpreadExport spreadExporter = new GridViewSpreadExport(this.radGridView1);
                spreadExporter.ExportVisualSettings = true;
                SpreadExportRenderer exportRenderer = new SpreadExportRenderer();

                spreadExporter.RunExport(filename, exportRenderer);

 

Thanks.

Hello,

In our Environment it's not possible to assign a GroupComparer to another GridView template then MasterTemplate. The GroupComparer property is always null after assignment.

It's possible to assign our custom comparer to the MasterTemplate and it will be triggered, but not in another template then MasterTemplate.

Best regards.

Using a custom control using the Telerik Presentation Framework, I am receiving a NullException inside the GridCheckBoxHeaderCellElement during the GridViewElement's data load.

The custom control construction follows an example I found somewhere (reference is lost to me at this point):

ControlContainingGridView inherits from RadControl

CreateChildItems creates and adds ControlContainingGridViewElement

 

ControlContainingGridViewElement inherits from RadElement

CreateChildItems creates and adds some layout controls AND a GridViewElement

 

public partial class ControlContainingGridView : RadControl {
        public ControlContainingGridView() {
            InitializeComponent();
            this.TextChanged += ControlContainingGridView_TextChanged;

During Form load, I programmatically add columns and provide a binding source

 

private List<SampleModel> sampleModels = new List<SampleModel>();
        private BindingSource sampleModelsBinding = new BindingSource();

        private void RadForm1_Load(object sender, EventArgs e) {

            sampleModels.Add(new SampleModel() {
                When = DateTime.Parse("1980-04-23"),
                SomeText = "Purple Bananas",
                IsTrue = true
            });
            sampleModels.Add(new SampleModel() {
                When = DateTime.Parse("2002-07-20"),
                SomeText = "Ball & Chain",
                IsTrue = false
            });
            sampleModelsBinding.DataSource = sampleModels;

            controlContainingGridView.SetupColumns((grid) => {
                grid.AddDateTimeColumn(nameof(SampleModel.When), "When");
                grid.AddTextBoxColumn(nameof(SampleModel.SomeText), "Some Text");
                grid.AddCheckBoxColumn(nameof(SampleModel.IsTrue), "Is True");
            });

            controlContainingGridView.DataSource = sampleModelsBinding;

        }

 

Inclusion of the CheckBox column results in the following error:

Add a combo-box column that point to a field with Guid data type, add summary item to this columns as well.

Workaround: 

private void RadGridView1_CreateRowInfo(object sender, GridViewCreateRowInfoEventArgs e)
{
    if (e.RowInfo is GridViewSearchRowInfo)
    {
        e.RowInfo = new MySerachRow(e.ViewInfo);
    }

}
class MySerachRow : GridViewSearchRowInfo
{
    public MySerachRow(GridViewInfo viewInfo) : base(viewInfo)
    {
    }

    public override string GetCellFormattedValue(GridViewRowInfo row, GridViewColumn column)
    {
        if (row is GridViewSummaryRowInfo)
        {
            return "";
        }
        return base.GetCellFormattedValue(row, column);

Add a new DeferredFilter property on RadGridView level which controls whether the filtering logic will be immediately preformed on each key stroke or only by pressing Enter.
Under Review
Last Updated: 27 Jun 2019 09:40 by ADMIN

Please refer to the attached gif file. You will notice that for the GridViewMaskBoxColumn  with numeric mask the filtering doesn't work. For the other columns each key stroke filters the grid rows.

Workaround: either use a GridViewDecimalColumn or change the default editor for the GridViewMaskBoxColumn :


            this.radGridView1.EditorRequired += radGridView1_EditorRequired; 

        private void radGridView1_EditorRequired(object sender, EditorRequiredEventArgs e)
        {
            if (this.radGridView1.CurrentColumn.HeaderText == "MaskBoxColumn")
            {
                GridSpinEditor spinEditor = new GridSpinEditor();
                RadSpinEditorElement element = spinEditor.EditorElement as RadSpinEditorElement;
                element.ShowUpDownButtons = false;
                e.Editor = spinEditor;
            }

RadGridView

NEW
  • New property inside GridViewSearchRowInfo: DeferredSearch. Gets or sets a value indicating whether grid will wait until enter key is pressed before it starts a search.

 

 

I have implemented this and it is exactly what I want and need, Thank you! 
However I thought I might point out that when you tab out it doesn't implement the search, only when you press enter.

And when you press the X to clear the search it clears the text box but not the search. the count of found and the highlighted finds remain

In my gridview need support of different heights of rows. I solved it with the autosize property.

But now I have a side action that the header row and filter row also react to the autosize property.

Attached you can see this behaviour...

Here my code:

Grid.MasterView.TableFilteringRow.MinHeight = 40
Grid.AutoSizeRows = True

Is there a chance to separate data rows from filter and header row?

 

Regards,

Dimitri

  3. The rows return to unsorted.
  4. Scroll down slightly and scroll back up and the sort is restored.

This happens after calling RunExport.

GridView is not correctly drawn if it's not populated and the theme is set to "TelerikMetro" or "TelerikMetroBlue" (the bottom line is missing). 

Steps to reproduce the behavior: create a RadForm, add a RadGridView to it and set the theme to "TelerikMetro" or "TelerikMetroBlue" by using ThemeResolutionService.ApplicationThemeName.

Hello,

I am having issues with DateTime editor in the grid. We have custom date/time format for our dates - "HH:mm:ss dd-MMM-yyyy" and the datetime editor is set to free form date time with this mask. When user typed a value in the editor it is passed to FreeFormDateTimeProvider.Validate method, which calls DateInput.ParseDate. DateTimeLexer splits this kind of values just fine, but obviously time related tokens comes first and then the date related tokens.

Unfortunately DateTimeParser.Parse method is made the way that it parse date at first and then time from the tokens list. In my case this means time value is parsed and the date value is dropped to default. Why didn't you check that if after ParseDate and ParseTime calls the date portion is null but there are still remaining tokens in the list, so you may call ParseDate one more time?

Do you have any suggestion how could I resolve this issue? Everything related to date time parsing is not extendable at all, starting from DateInput, most of the classes and methods are not public and even some public methods are not virtual. Can I have the Telerik free form date time typing capabilities in the editor but still have time part before date part?
