To reproduce:

1. Bind a RadGridView to the Northwind.Products table

2. Enable the header checkbox for the Discontinued column

3. Set the ReadOnly property either for the grid or for the specific column.

The header checkbox is not allowed to be toggled. However, you can toggle/untoggle it which affects all the data rows.

Please refer to the attached sample project. 

If the main Cars list is not empty, the child templates have correct captions:

However, if initially there are no Cars and you add a new one via the new row, the captions of the child template remains with the default value ("table"):

Hi

Please find attached sample project having 2 different reference folder(Telerik2018,Telerik2020) for Telerik.

Code flow & Issue description: I have Event "radGridView1_EditorRequired" in which i have attached another event on value changed "Editor_ValueChanged" in which we get data gron DropdownListElement using ((RadDropDownListElement)(sender)).SelectedValue.
Issue is when we use version (2018.3.1016.40) we get selected value text, in case of current version (2020.1.218.40) we get null value.

Current version DLL  2020.1.218.40 (Issue in current version)

I have a radGridView with MutliSelect set to true and SelectionMode set to FullRowSelect. A theme is applied, and this behavior is seen with other themes too. Several columns are pinned to the left.

When I multi-select rows using the shift or control buttons by clicking one of the cells under the frozen columns, the row is selected and colored accordingly, except for the cell that was actually clicked which remains with the unselected color.

If I multi-select by clicking on one of the cells under an unpinned column, the full row is selected as expected.

In the image below, I held down shift and selected the first and third row in sequence under the Officer column.

How can I fix this to show the complete row selected?

Hi

Note : Issue in Current version of Telerik (2020.1.218.40)

On cheked of GridViewCheckBoxColumn (Multiple rows) in GridView grdFrReview_HeaderCellToggleStateChanged fires and header checkbox get checked. Header checkbox should check only if all check-boxes of current page checked, otherwise header checkbox should not checked. This was working fine in my previous version of Telerik (2018.3.1016.40).

In the screenshot shown i have checked 1st and then 2nd row of grid, you can see its headercheckbox status has been checked.

Please refer to the attached sample project. When the expander is in the columns that contains long text that has be resize the rows, the AutoSizeRows functionality doesn't work properly:

Workaround: set the MasterTemplate.SelfReferenceExpanderColumn property to a column that contains very short content:  

Me.RadGridView1.MasterTemplate.SelfReferenceExpanderColumn = Me.RadGridView1.Columns(1)

Now, I have 2 problems:

1. Checking / Unchecking header check box, checks/unchecks checkboxes of current page only.  I need to perform the operation for the whole grid.

2. I have got filters on.  User can select filters on columns.  Once filters are applied, records are displayed according to those filters (other records are hidden).  Now, when checking the header check box, it only selects records that are part of current page.  For example, if I am on first page and apply filter on one column, grid will hide all rows from the first page that do not match the filter and pull records from 2nd and 3rd pages that match the criteria and show on the first page.  But if I select check box in the header, then only records from first page are selected, records that came from 2nd and 3rd page are not selected.

Hello,

I am using a radGridView on a Windows touch screen. When I am trying to scroll the rows by hand (EnableKineticScrolling was set to true), the scrolling process is very slow. If I will use the vertical scrollbar, then it is ok. How can I achieve this without using the vertical scrollbar?

I used EnableFastScrolling=true, but I did not see any improvement.

 

Regards,

Yannis

Hi,

when I select the column chooser multiple times via context menu, the column chooser dialog scales multiple times.

Reproduced here with the Telerik sample application. 150 % dpi scaling.

I'm just starting with RadGridView and trying to figure out how to create a combobox column inside my RadGridView.  I've added a column that is of type GridViewComboBoxColumn.  I've created a BindingSource that Contains the values for the combobox.  I can't figure out how to set the datasource property of the Column to use that BindingSource.  Google search says to set the datasource property but when I'm going through the "Open Properties Builder"  and I select my combobox column I don't see that property listed under advanced for the column.

Thanks

Lee

If you want to use Conditional Formatting via code (expression based formatting) you will see that it throws an exception if you set TRIM() condition.

ExpressionFormattingObject expressionCondition = new ExpressionFormattingObject(
expressionCondition.Expression = "TRIM(ContactName) = 'Maria Anders'";
expressionCondition.CellBackColor = Color.Aqua;
this.radGridView1.Columns["CustomerID"].ConditionalFormattingObjectList.Add(expressionCondition);

There is no exception if you use the same condition via "Conditional Formatting Rules Manager" form.

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;
            }
        }

It seems that the GridViewColumnGroup.MinHeight has a big influence on the height of the filter cell.

Workaround:

this.radGridView1.AutoSizeRows = true;

I am currently working in Telerik v2019.3.917 and .Net 4.5.2. I have multiple theme's setup for a local application for my users but I am seeing something odd with the Telerik.WinControls.Themes.HighContrastBlack theme. It appears that I am unable to select more than one cell in this theme. My grid has multiselect as true and SelectionMode as CellSelect. I have tried holding ctrl and clicking cells, clicking the row header, holding the mouse down and dragging, and using Ctrl+A but none of these select more than one cell.

I am setting the application theme on launch:

var _t = new Telerik.WinControls.Themes.HighContrastBlackTheme();
ThemeResolutionService.ApplicationThemeName = "HighContrastBlack";

 

Themes that work: All Fluents, All Material, All VS.

Is this a bug or am I missing something?

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

To reproduce: please run the attached sample project and follow the steps illustrated in the attached gif file:

Scrolling to a newly added row does not work when inner templates are visible.

Add data to the inner templates of several rows near the bottom using the button.
Expand these inner templates so they are all visible.
Scroll back up to the top.
Add a new item to the outer grid normally.
The table will jump to where it things the new item is but will fall short, instead scrolling to a location in one of the inner templates.
Workaround:

        private void RadGridView1_UserAddedRow(object sender, GridViewRowEventArgs e)
        {
            foreach (GridViewRowInfo    row in this.radGridView1.Rows)
            {
                if (row.IsExpanded)
                {
                    row.IsExpanded = false;
                    row.IsExpanded = true;
                }
            }
        }
