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();
            
        }​

I have a problem with the way ColumnGrouping is handling a GridViewTextBoxColumn.  I have recreated the problem in a very simple code snippet.  I am attaching a screen image of how it is rendered and the code that populates the table.

What am I doing wrong?

radGridView1.Visible = false;
radGridView1.Columns.Clear();
radGridView1.Rows.Clear();
radGridView1.SummaryRowsTop.Clear();
radGridView1.Refresh();
//radGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
// Handle Planning Group definitions if provided.
ColumnGroupsViewDefinition ColView = new ColumnGroupsViewDefinition();
ColView.ColumnGroups.Add(new GridViewColumnGroup("SYSTEM"));
ColView.ColumnGroups.Add(new GridViewColumnGroup("DETAILS"));
ColView.ColumnGroups[0].Rows.Add(new GridViewColumnGroupRow());
ColView.ColumnGroups[1].Rows.Add(new GridViewColumnGroupRow());
radGridView1.TableElement.BeginUpdate();
GridViewTextBoxColumn gt = new GridViewTextBoxColumn("System");
//gt.MaxLength = 40;
gt.AutoSizeMode = BestFitColumnMode.None;
radGridView1.MasterTemplate.Columns.Add(gt);
ColView.ColumnGroups[0].Rows[0].Columns.Add(radGridView1.Columns["System"]);
for (int x=1; x<10; x++)
{
radGridView1.MasterTemplate.Columns.Add(new GridViewDecimalColumn(x.ToString()));
ColView.ColumnGroups[1].Rows[0].Columns.Add(radGridView1.Columns[x.ToString()]);
}
radGridView1.ViewDefinition = ColView;
// Add data rows
for (int y=1; y<20; y++)
{
// Populate the columns for this system
object[] columns = new object[10]; // Allocate a new array
columns[0] = "System"+y.ToString();
for (int c=1; c<10; c++)
{
columns[c] = Convert.ToDecimal(y*c);
}
radGridView1.Rows.Add(columns);
}
// Done populating grid
radGridView1.TableElement.EndUpdate();
radGridView1.Columns[0].IsPinned = true;
radGridView1.Columns[0].PinPosition = PinnedColumnPosition.Left;
radGridView1.Refresh();
radGridView1.Visible = true; 

Hello:

 When I set uxTreeView.SelectedNode = someNode, if the newly selected node is out of view, the RadTreeView control is scrolled so that the newly selected node is in view and visible.  How do I prevent the scroll from occurring?  I want to select a node that may be out of view, but don't want the node to be scrolled into view.

 Thanks!
