Setting the theme name during form initialization does not change the form's theme.

I need to know if RadToolbarForm is derived from RadForm.

Thanks.

I have many Collapsible Panels in my Scrollable Panel, what I need it to do, is if the user expands a panel, I need that panel to scroll to the top of the scrollable panel.   Is there a way to pragmatically do this?

TIA.

Hi Team,

Except first 2 parameters the remaining params are throwing an error. Please refer the attached screenshot and code block below . Could you please help to solve this issue?

Note: Its working fine in Telerik.WinControls.GridView.dll 2013.3.1127.40

private void BtnInsertNPAPrice_Click(object sender, EventArgs e)
{
   try
   {
	   if (GridView.Rows.Count > 0)
	   {
		   if (GridView.DataSource != null && ((DataTable)GridView.DataSource).Rows.Count > 0)
		   {				 
			   this.GridView.Rows.Add("Test", "875", 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0);										 
		   }
	   }                  
   }
   catch (Exception ex)
   {
	  RadMessageBox.Show(ex.Message, Common.ErrorMsgHeader, MessageBoxButtons.OK, RadMessageIcon.Error);

I'm using a split container to display or hide a "comment history" list view element in a details view. One column contains created DateTime values and the other contains string values of comments a user of the application left.

I use the following cell formatting event code to enable text wrapping on my cells.

private void radListView1_CellFormatting(object sender, ListViewCellFormattingEventArgs e)
        {
                e.CellElement.TextWrap = true;
        }

When the form loads everything, the cells look correct. Fully expanded and no clipped text. When I collapse the panel with the splitter buttons and "hide" the list view element and reopen the panel using the splitter buttons then the text is clipped. See attached files for reference of how I want them to look.

I've tried using RadListView.Refresh() in a dozen different event calls, RadListView.ListViewElement.Update(UpdateLayout) in a dozen different event calls, a synchronizationContext.Post() of the Refresh method in a dozen different event calls, and even direct formatting of the UI hierarchy elements Text Wrap property to true to no avail.

I have the following properties set as indicated in various tutorials for the ListView control:

• AllowArbitraryItemHeight & ...Width = True
• AutoSizeColumnsMode = Fill
• Dock = Fill
• ViewType = DetailsView

I have the following properties set for the parent SplitPanel control:

• Dock = Fill

For other relevant properties, I can confirm on a case by case basis since I'm not sure what I'm missing in my problem. Any guidance or advice is very appreciated.

Hi Team,

ToggleState.On : ToggleState.Off; } catch (Exception ex) { RadMessageBox.SetThemeName("Office2007Silver"); RadMessageBox.Show(ex.Message, res_man.GetString("ProposalEntityMaster", PNxt_BL.Common.CultureInfo), MessageBoxButtons.OK, RadMessageIcon.Error); } using (InsertTableForm insertForm = new InsertTableForm()) { insertForm.Owner = this; insertForm.ThemeName = "Office2007Silver"; if (insertForm.ShowDialog() == System.Windows.Forms.DialogResult.OK) { this.radRichTextBox1.InsertTable(insertForm.RowsCount, insertForm.ColumnsCount); } } this.radRichTextBox1.DocumentView.Caret.Hide(); }

Hello,

is it possible to somehow activate a funktion to drag and hold an appointment to the latest possible date and the scheduler will after a few seconds of holding the appointment in this position automatically change the displayed calender to for example the next week so that you can drop the appointment here?

Paul
