Has anyone else noticed in the most recent release that after expanding and collapsing a particular group of nodes twice the vertical scroll bar disappears? If you're towards the bottom of the list this bug makes it where you cannot access the nodes out of the initial collapsed view.

Luckily in my application I have an "Expand/Collapse" button which by calling either the CollapseAll() or ExpandAll() on the RadTreeView returns the vertical scroll bar.

Currentrow Details

I have two gridviews on a form, each is grouped by the same column name. I want to capture the text in the group header of gridview1 as the groupexpanded event fires but when I attempt to get this information using 'sender.currentrow.headertext' visual studio crashes.

When I have the information I want to loop through the rows in gridview2 and expand the equivalent group if one exists.

Is this a bug or is my approach wrong?

Self relation multi-select not working

I've set the MultiSelect to true but I cannot select more than one row. Is this feature not available with a self-relation hierarchy gridview?

Being able to select more than one row is very important to the application I'm working on.

Thanks for your help.

Autosizerows not working properly

Hello,

I want to create a grid where one record is shown on 2 lines. I have done this by using the htmlviewdefenition.
When I enlarge the font size and then set the autosizerows property to true, the header isn't displayed properly. (Attached you will find a screenshot of the grid)

My code:

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

using Telerik.WinControls.UI;

namespace TestTelerikGrid3

{

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

HtmlViewDefinition view = new HtmlViewDefinition();

view.RowTemplate.ReadXml("GridLayout.htm");

radGridView1.ViewDefinition = view;

radGridView1.Font = new Font("Segoe UI", 15.75F,FontStyle.Regular);

radGridView1.AutoSizeRows = true;

}

Html:

<table>

<tr>

<td colspan="2">Column1</td>

</tr>

<tr>

<td>Column2</td>

<td>Column3</td>

</tr>

</table>

I am using gridview version 2011.1.11.419.

Can anyone help me with this problem?

Bug in RibbonBar resizing

I am using the Ribbon bar. I am attaching a screen shot of the ribbon as shown in my application.

When the user minimizes the application, and then restores it, the ribbon buttons are messed up as you can see from the second screen shot I am attaching. Notice that any buttons that are in button groups no longer have any text.

If the user clicks the up arrow in the upper right corner to hide and then show the toolbar, it resizes back to the original display.

Is this a known bug? Any idea on how soon it will be fixed?

Thanks!

Create an Excel Dropdown list with ExportToExcelML

Dear Telerik Team,

Is it possible to create a custom Drop Down list (validation list) in the Excel worksheet when exporting the RadGridView with ExportToExcelML (VB.net code)?

I;m giving herebelow an example of code to create a drop down list using the Excel Interop assemblies but which I'd like to use/convert with the faster ExportToExcelML method:

Private Sub AddCategoryValidationList(ByVal rng As Excel.Range)

With

rng.Validation

.Add(Excel.XlDVType.xlValidateList, _

Excel.XlDVAlertStyle.xlValidAlertStop, _

1,

"=Beneficiaries!$A$1:$A$1000")

.InCellDropdown =

True

.ErrorTitle =

"Stock release form"

.InputMessage =

"Please select a beneficiairy"

.ErrorMessage =

"The value you have entered is not a " & _

"valid beneficiary. Please select a beneficiary from " & _

"the list."

.ShowInput =

True

.ShowError =

True

End With

End Sub

Best regards,
Alain Cavenaile
