Hi,

I have the following grid, all the GridBoundColumn's populate when the grid is loaded but the radcombobox does not. How can I get it to display the current value? Does anyone have an example of a radgrid where one of the columns is a drop down or combo box?

Thanks for any help in advance,

[Solved] ListView binding issue

Hi guys!
We've been using Telerik.Web.UI v.2010.1.309.35 in our project, and recently have switched to v.2010.1.519.35 . Since that I've discovered that ListView doesn't seem to process <%%> tags correctly during binding. For instance, here's the EditItemTemplate that I have:

<EditItemTemplate>

<tr>

<td style="vertical-align:top">

<rlt:TextBox ID="txtDurationMonth" runat="server"

ValueType="Integer"

Width="50px"

Text='<%#Eval("DurationMonth") %>'

></rlt:TextBox>

<asp:RangeValidator runat="server"

ControlToValidate="txtDurationMonth"

ErrorMessage="Integer value required"

MinimumValue="0"

MaximumValue="<%#int.MaxValue %>"

Type="Integer"

SetFocusOnError="true">

</asp:RangeValidator>

</td>

<td style="vertical-align:top">

<rlt:LinkButton ID="lbSave" runat="server"

CommandName="<%#RadListView.UpdateCommandName%>" CommandArgument='<%#Eval("Id") %>'>Save</rlt:LinkButton>

</td>

</tr>

</EditItemTemplate>

When I switch into Edit mode, I started getting an exception that it cannot parse '' (empty string) for MaximumValue of rangevalidator. I removed that validator at all and it switched fine, but CommandName of lbSave was always empty. Also, ListView has DataKeyNames="Id" However, if I try to get an ID in ListView ItemCommand handler like this:

((

RadListViewDataItem)e.ListViewItem).GetDataKeyValue("Id")

I get "index was out of range" exception. So I had to switch back to v.2010.1.309.35. And now it works as it should, but that version has an issue with RadEditor, which is being stretched in some occasions.
So, is it some bug or do I miss something? Thanx in advance!

Masterpage & Ajaxloadingpanel

I've got a Masterpage with an Ajaxmanager & loading panel on & 2 content panels. Content1 is a menu and Content2 is the actual aspx pages for the application where 100% of the application is loaded. On the screens there are save & cancel buttons with code behind procedures. I want to be able to show the loading panel when clicking save or cancel or even when an aspx page is loading.

Is this achievable and how?

Group Headers not appearing while exporting to excel

Hi Telerik Team,

The issue is my group headers are not coming while exporting since I am writing the following code:
if (e.Item is GridGroupHeaderItem)
{
(e.Item as GridGroupHeaderItem).DataCell.Visible = false;
e.Item.PreRender += new EventHandler(Item_PreRender);
}
which is hiding the GroupHeaders DataCell since I need to customize the header as demonstrated in the following link
http://www.telerik.com/help/aspnet-ajax/aligning_items_in_groupheader2.html

Now,Please let me know with (e.Item as GridGroupHeaderItem).DataCell.Visible = false;
and creating my own Table cells for the group header how can I bring the group header while exporting to excel?

I think export to excel takes group headers from Datacell only it does not identify anything else.Since I am adding table cells manually in the header it is not getting those.Please let me know how to resolve this issue?
Regards,
Shubh

Input controls in Grid not setting Dirty flag

Using jQuery to track changes on a form automatically sets the dirty flag for all controls at the form level, but controls (TextBox, DropDownList) inside a Grid edit row are not captured. We are using the $(":input").change() method to capture changes in input controls. Is there any automated way to capture the controls inside the Grid edit row?

OnClientSelectedIndexChanged fires twice

Hi guys,

I am trying to do some logic when a new value is selected from the combobox.

I hooked up a callback function to the OnClientSelectedIndexChanged event. When I select a new element the event fires and when I click anywhere else ( the Combobox will lose focus) the event will fire again.

How can I overcome this?

[Solved] Too many Telerik controls causes style loss in IE

I'm having this problem:

http://www.technullogy.net/index.php/2010/03/05/internet-explorer-limits-css-and-script-resources-to-30/

To duplicate it, try adding one of each Telerik control to a page, then open the page in IE and see if all them appear correctly. I have a page that has several different Telerik controls (RadAjax, RadTooltip, RadTabStrip, RadDate and Time Pickers, RadEditor, etc). If I count all of the WebResource.axd references that IE 8 is making, it's over 30. If I remove a couple Telerik controls, then the remaining controls get their style back.

They all appear perfect in Firefox 3.6.8, Chrome and Safari, so I know it's an IE 8 issue. Is Telerik aware of this? Is there any way around this?

Self-referencing Hierarchy and DetailTable count

Hi,

I have a self-referencing hierachical radGrid. I am loading data thru the NeedDataSource event handler. When I have 3 levels of hierarchy, the gridInstance.MasterTableView.DetailTables.count shows 1 , MasterTableViewDetailTables[0].DetaitTables.count is 1, so far so good. Now when I look at the last (the lowest level) GridTableView, its DetaitTables.Count is also 1 whereas this GridTableView does not have any children. What am I missing? Is the DetailTables count always 1 when using Sel-Referencing Hierarcy? even for the GridTableView which has no chidren? Using RadControls for Ajax 2010_1_519 and Framework 3.5.

Thanks in advance for your help.
