Grid MasterTableView disappears with move to 2012 Q3 version from 2010 Q3

I'm using Grid Template Column with checkboxes. Grid loads normally but MasterTableView disappears when you are clicking any checkbox in .Grid Template Column. Worked fine in 2010 Q3. Problem happened with move to 2012 Q3. Project was updated through VS2010 Telerik menu: Update to the latest version.

Grid Template Column:

<telerik:GridTemplateColumn UniqueName="CheckBoxTemplateColumn" AllowFiltering="False">

<HeaderTemplate>

<asp:CheckBox id="headerChkbox" OnCheckedChanged="ToggleSelectedState" AutoPostBack="true" runat="server"></asp:CheckBox>

</HeaderTemplate>

<ItemTemplate>

<asp:CheckBox id="CheckBox1" OnCheckedChanged="ToggleRowSelection" AutoPostBack="true" runat="server"></asp:CheckBox>

</ItemTemplate>

<HeaderStyle Width="95px" />

</telerik:GridTemplateColumn>

Code behind:

Protected Sub ToggleSelectedState(ByVal sender As Object, ByVal e As EventArgs)

Dim headerCheckBox As CheckBox = CType(sender, CheckBox)

For Each dataItem As GridDataItem In OMSGrid.MasterTableView.Items

CType(dataItem.FindControl("CheckBox1"), CheckBox).Checked = headerCheckBox.Checked

dataItem.Selected = headerCheckBox.Checked

Next

End Sub

Protected Sub ToggleRowSelection(ByVal sender As Object, ByVal e As EventArgs)

CType(CType(sender, CheckBox).NamingContainer, GridItem).Selected = CType(sender, CheckBox).Checked

End Sub

Protected Sub OMSGrid_ItemCreated(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles OMSGrid.ItemCreated

If TypeOf e.Item Is GridDataItem Then

AddHandler e.Item.PreRender, AddressOf OMSGrid_ItemPreRender21

End If

End Sub

Protected Sub OMSGrid_ItemPreRender21(ByVal sender As Object, ByVal e As EventArgs)

If Not CType(sender, GridDataItem)("CheckBoxTemplateColumn").FindControl("CheckBox1") Is Nothing Then

CType(CType(sender, GridDataItem)("CheckBoxTemplateColumn").FindControl("CheckBox1"), CheckBox).Checked = CType(sender, GridDataItem).Selected

End If

End Sub

This code is from Telerik code samples. Again, it's working fine with 2010 Q3.

Thank you for your help.

Regards,

Vitaly

IE8 HTTPS with Iframe and RadAjaxPanel

Hello,

I'm using OLAP Pivot Grid with HTTPS protocol and it gives a warning saying "This page contains both secure and nonsecure items" on IE8 for some specific scenarios. I have loaded the pivot grid in an iframe and wrapped with a RadAjaxPanel. I have attached a sample project and screenshot of the mentioned security warning (rename the extension of test_project.jpg as test_project.rar).

Steps to reproduce :

1) Deploy attached project and load main.aspx using https protocol.
2) Add a dimension attribute field to "ROW FIELDS" / "COLUMN FIELDS"
3) Click on filter button of added attribute field
4) Apply any value or label filter (EX: Equal filter)
5) Again click on filter button of added attribute field
6) Then you will be able to see the security warning.

This warning only appear when both iframe and update panel is used with pivot grid and its a must to have both in my project. how can i fix this issue without removing any of those.

Thanks and Regards,
Yohan

Setting Text in Cell removes Expand-Icon

Hi,
i need a custom filtering in my PivotGrid that is not alphabetically. Therefore i added a leading number to the data by which the grid is sorted and remove these numbers in the OnCellDataBound method like this
e.Cell.Text = ((string) e.Cell.DataItem).Remove(0, 2);
That causes the expand icon to disappear.

BR, Matthias.

Missing skins in Q1 2014.1.225.40 release

I upgraded to RadControls for ASP.NET AJAX yesterday and noticed that some of the previous skins are missing. I wrote some code to iterate through the RadSkimManager.GetSkinChooser().Items collection and here is what I am seeing:

Black
BlackMetroTouch
Default
Glow
Metro
MetroTouch
Office2007
Office2010Black
Office2010Blue
Office2010Silver
Outlook
Silk
Simple
Sitefinity (Obsolete)
Sunset
Telerik
Vista
Web20
WebBlue
Windows7

I see that Hay and Forest are not in this list anymore. Have these skins been removed?

Thanks,

IE11 When EmptyMessage is set OnSelectedIndexChanged event fires during every post back and properties SelectedIndex, SelectedItem have wrong values

Set up info:
Telerik version: 2013.2.611.40
Browser: IE 11.0.9600.16476
.NET Framework: 4.0

Symptoms: During Asynch Post Backs when EmptyMessage property is set AND text of the first item is not English (eg. German, Greek) then OnSelectedIndexChange event fires every time although index has not been changed. Further more properties SelectedIndex, SelectedItem and SelectedValue have the wrong values of -1, null and "" respectively

I have prepared a small project to demonstrate the bug but your forum allows only picture format attachments. So here is the test code:

If you remove the EmptyMessage property or you set it to "" everything goes back to normal.
Also if you comment out line line 36 and you uncomment out line 38 so that first Items text is English then every goes back to normal as well. So I think it should be an issue of the EmptyMessage property and the Encoding of the Items text in the JavaScript you are using.

Thank you for your time and I remain to your disposal for any additional info you may need

Changing Font Size

Is there a recommended way to change the font size across all the telerik controls? I want to use one of the skins but the font is too big.

Thanks in advance.
