Cannot find a column with UniqueName 'FileID' on my TemplateColumn

Hi, I have a template column titled 'FileID' and am trying to access it. Unfortunately whenever it comes across a template column, it will error out saying that FileID is not a column.

ASPX:

<telerik:GridTemplateColumn DataField="FileID" HeaderText="File / Link" HeaderStyle-Width="55px" SortExpression="FileID" HeaderStyle-ForeColor="White" AllowFiltering="false" ItemStyle-Width="20%" ItemStyle-Wrap="true" ShowSortIcon="false">

<ItemTemplate>

<asp:HyperLink ID="hlLink" runat="server" Target="_blank" Visible="false"></asp:HyperLink>

</ItemTemplate>

</telerik:GridTemplateColumn>

From this you can see that my GridTemplateColumn's DataField is named "FileID"

VB.NET:

For Each col In dg.Columns

If (col.GetType() Is GetType(Telerik.Web.UI.GridBoundColumn)) Then

If col.HeaderText = ColumnName Then

If HideOrShow Then

dg.MasterTableView.GetColumn(col.DataField).Display = True

Else

dg.MasterTableView.GetColumn(col.DataField).Display = False

End If

Else

If (col.GetType() Is GetType(Telerik.Web.UI.GridTemplateColumn)) Then

If HideOrShow Then

dg.MasterTableView.GetColumn(col.DataField).Display = True

Else

dg.MasterTableView.GetColumn(col.DataField).Display = False

End If

Next

And this is what throws the error: dg.MasterTableView.GetColumn(col.DataField).Display = True underneath the TemplateColumn part.

Did I not name the column correctly? I thought DataField was what I used, and it works on the rest of the BoundColumns. Can I get some pointers here?

Thanks!

[Solved] Javascript errors being thrown in IE10 after upgrading controls

Hello,

We've recently upgraded our Telerik asp.NET controls to v2014.1.403.40

We noticed that when browsing our pages in IE10 many different javascript errors are being thrown. Such as "Error: Unable to get property 'PageRequestManager' of undefined or null reference" We've done testing with IE11 and IE10 in compatibility mode and both are working properly. This problem is also affecting our screen layouts.

Let me know if you need more information to investigate this problem.
Thanks.

[Solved] Align images at top of the ImageGallery

Hi,

Is it possible to vertically align images so that they appear at the top of the ImageGallery display area? We have images that vary in height, and would like to have the placement of where the images are displayed to be consistent. Currently the position of the image shifts depending on which image is being viewed. I'm assuming the default behaviour of the image gallery is to display the image centered both horizontally and vertically?

Thanks!

Hi,

I have a HTMLChart containing 19 series(x:DateTime, y:Double) each containing approximately 240 values.
Each point have a tooltip that uses kendo.format to show the DateTime and the double.
Transition is set to false.
MinorGridLine is set to false.
MarkersAppearance size set to 2 and square type.
LineAppearance size set to 2.

It render fine in IE9 and +.
But I have to support IE8, the rendering is very slow and the popup about slow script is showing up.

Any way to improve performance or to render differently or partially the chart?

Thank you.

TreeView in RadPane in RadSplitter Issue

After upgrading to version 2012.3.1205.40, the following code:

<telerik:RadSplitter ID="trsCWCMPrimary" runat="server" BorderWidth="0" BorderSize="0" BorderStyle="None" Height="520px" LiveResize="true" Orientation="Vertical" ResizeMode="Proportional" Width="100%">

<telerik:RadPane ID="trpCWCMPrimaryTree" runat="server" Collapsed="false" Width="20%">

<telerik:RadTreeView ID="trtvCWCMPrimary" runat="server" CssClass="sfecua_chkrdo_dataLeftSmall" Height="99%" Width="100%" OnNodeClick="trtvCWCMPrimary_NodeClick" OnNodeCollapse="trtvCWCMPrimary_NodeCollapse" OnNodeExpand="trtvCWCMPrimary_NodeExpand" onclientnodeclicking="OnClientNodeClicking">

</telerik:RadTreeView>

</telerik:RadPane>

<telerik:RadSplitBar ID="trsbPrimarySecondary" runat="server" CollapseMode="Forward"></telerik:RadSplitBar>

<telerik:RadPane ID="trpCWCMSecondaryTableDetails" runat="server">

</div>

</div>

</div>

</telerik:RadPane>

</telerik:RadSplitter>

</td>

</tr>

No longer reacts as expected.

Previously, the RadTreeView in the left RadPane would be cut off (scroll bars appear) as the RadSplitBar was moved left. The rendered controls (IFrames, etc) in the right RadPane would shrink as the RadSplitBar was moved right. The behaviour I want.

NOW, the RadTreeView nodes, text bleeds over the RadSplitBar when initially rendered and when the RadSplitBar is moved left. It's as though the right RadPane is sliding under the left RadPane. The RadTreeView is visible superimposed over the contents of the right RadPane.

I have to revert to version 2012.3.1016.40.
