Expanding DetailTable clears bound items on Master

Hi

I have a problem I can't seem to work out.

Basically I have a MasterTableView / DetailTable relationship. In the master table I am changing the checkbox to an image at the ItemDataBound event - this works fine.

However, when I expand the DetailView the images are removed and the checkboxes re-appear (coincidentially they are always unchecked).

Does anyone know how I should handle this situation so that when the details view is expanded the tick box images remain in the parent MasterTableView?

Many thanks
Carl

protected void RadGrid_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem)

{

GridDataItem item = (GridDataItem)e.Item;

var row = item.DataItem as Reporting.EntityModel.Stock;

if (row != null)

{

item["Active"].Controls.Clear();

if (row.Active == true)

{

item["Active"].Controls.Add(new Image() { ImageUrl = "/Assets/Images/tick_small_col.png" });

}

else

{

item["Active"].Controls.Add(new Image() { ImageUrl = "/Assets/Images/cross_small_col.png" });

}

How to hide data fields

I've got a RadTreeList but it's showing every thing including the ID and ParentID fields. How do I hide them?

Also, it is showing my URL field. How do I set the DataNavigateUrlField property so they work properly?

Thanks!

<telerik:RadTreeList ID="RadTreeList1" runat="server" ParentDataKeyNames="ParentID" DataKeyNames="ID" DataNavigateUrlField="WebAddress">

<Columns>

<telerik:TreeListBoundColumn DataField="Title" UniqueName="Title" HeaderText="Title" Visible="False" Display="False"/>

<telerik:TreeListBoundColumn DataField="WebAddress" UniqueName="WebAddress" HeaderText="" Visible="False" Display="False" />

<telerik:TreeListBoundColumn DataField="ID" UniqueName="ID" HeaderText="" Visible="False" Display="False" />

<telerik:TreeListBoundColumn DataField="ParentID" UniqueName="ParentID" HeaderText="" Visible="False" Display="False" />

Strange visual distortion

I've noticed sometimes when using the Telerik components we get some "visual distortion", which I think is best described by this image:

http://screencast.com/t/pzDqpbhWMw

In short, it seem to be a small black square that shows up sometimes. In this case, it is with a RadRotator, but doesn't show up for all the items. We've seen this with other telerik components as well from time to time. We have tried with several different browsers, and made sure they were set to 100% zoom.

Any ideas?

Telerik RadGrid SortExpressions Empty

Hello,

I am having an issue with the Telerik RadGrid controls. The issue I'm having is that when clicking on the header, it's only sorting ascending, even when the grid says its in descending order. I'm binding the entire results to the RadGrid (not doing custom paging or sorting). But for some reason, the sorting is not working...

The bigger problem is that when I click on the header, the RadGrid.MasterTableView.SortExpressions collection is empty. Why is this collection empty?

Thanks.

RadTextBox + RadInputManager

Hello,

I am able to use RadInputManager to validate required textbox controls, but it does not work with radtextbox controls. If a RadTextBox is left empty I would like a message to appear in the box with the exclamation mark.

Is there any way to get this to work? I assumed the RadTextBox was a child of TextBox, but this may be false as this only works on a TextBox.

This works on a textbox, but not a radtextbox :

<telerik:RadInputManager ID="RadInputManager1" runat="server">
<telerik:TextBoxSetting ErrorMessage="Required">
<Validation IsRequired="true" />
<TargetControls>
<telerik:TargetInput ControlID="TextBox1" />
</TargetControls>
</telerik:TextBoxSetting>
</telerik:RadInputManager>

Please advise
