Having complains from users when typing in a date for a GridViewDateTimeColumn

On the RadDateTimePicker there is an option called AutoSelectNextPart  (see code below)

Can this be used with the gridview, GridViewDateTimeColumn?

Many Thanks

Dim provider As MaskDateTimeProvider = TryCast(Me.dtpContractSigned.DateTimePickerElement.TextBoxElement.Provider, MaskDateTimeProvider)
provider.AutoSelectNextPart = True

Hi,

The Release Notes of 2015Q3 state that the drawing performance has improved for large trees. In my application I find that the redraw performance is substantially worse in this release than it was in earlier releases. Especially closing/opening nodes that are already loaded into memory (via NodesNeeded / Lazy loading) seem to perform worse than before. What's your experience with Tree Loading performance in 2015Q3?

I'm sure i'm missing something simple but the solution eludes me - i'm trying to use a RadContextMenu instead of the standard Windows.Forms.ContextMenu but receive the following error:

'Telerik.WinControls.UI.RadContextMenu' cannot be converted to 'System.Windows.Forms.ContextMenu'.

Any help or suggestions would be very much appreciated!

I've created a GridViewComboBoxColumn and now I need to get the combobox's dropdownclosed event. Or possibly it's selectedvalue changed event. How do I create the handlers for those. In VB code please.

Hey,

the data i'm aggregating contains a string value (eg. country) for each item.

I want to display the string value in the PivotGrid as followed:

There should be a column "Country" and the grouped items should display an empty string (since i see no good way to aggregate strings except maybe concatenating). When i open up the groups and drill down to a specific item, the "Country" column should display the country value for the item.

Is there any way to achive this?

Cheers,

Jens

Hi,

I am using a RadToggleButton and a RadDropDownButton in a RadRibbonBar.

The RadDropDownbutton does not have the "IsChecked" property. How do I get the same behavior ​than a RadToggleButton, meaning: If i click on the radDropDownButton i want it to have the same "visual behavior" as a normal RadTogglebutton;

I need it to change the backgroundcolor after a click like the togglebutton and to change it back if you click again.

thanks for any help

Hello,

Very new to Telerik Components.

 I am using Telerik Gridview with different column types like multicombobox, decimal, combo box etc., Now I need to do validation each cells and written code for validation in CellValidating event of Gridview. it is  validating  properly. but I need to clear the cell content which is not happening.

I red other articles regarding the same and i initialize a cell validating event in the editor (Multicombobox editor). in this case the event itself is not firing.

kindly help me sort this issue.

 I am attaching code snip shot for your ref.

Grid level Cell validation event

private void grddisplaygrid_CellValidating(object sender, CellValidatingEventArgs e)
        {
            e.Cancel = true;
            grddisplaygrid.CurrentRow.Cells[0].Value = string.Empty;
            }​

in editor level (keydown event is firing but the validaiting event is not firing

-----------------------

private void grddisplaygrid_CellEditorInitialized(object sender, GridViewCellEventArgs e)
        {
                if (this.grddisplaygrid.CurrentColumn is GridViewMultiComboBoxColumn)
                {
                    RadMultiColumnComboBoxElement editor = e.ActiveEditor as RadMultiColumnComboBoxElement;
                    if (editor != null)
                    {
                        iscellintialized = true;
                        editor.EditorControl.EnableFiltering = true;
                        editor.AutoCompleteMode = AutoCompleteMode.SuggestAppend;
                        editor.ClearTextOnValidation = false;
                        editor.Text = "";
                        RadMultiColumnComboBoxElement editorElement = editor.EditorElement as RadMultiColumnComboBoxElement; //_gridEditor.EditorElement as RadItem;
                        editorElement.KeyDown += new KeyEventHandler(MultiComboboxeditor_KeyDown); //.KeyDown += new KeyEventHandler(radGridView1_KeyDown);
                        editorElement.Validating += new CancelEventHandler(editor_validaitng);
                        editorElement.Validated += new EventHandler(editor_validated);
                    }
                }
            }

        private void editor_validated(object sender, EventArgs e)
        {
            throw new NotImplementedException();
        }

        private void editor_validaitng(object sender, CancelEventArgs e)
        {
            //throw new NotImplementedException();
            
        }​
