Hello,

I need to change the text inside the ContextHeaderMenu in  a radgrid.

I have the following code on my Page_Load:

AddHandler RadGridTransmission.HeaderContextMenu.ItemCreated, AddressOf Me.ContextHeaderMenu_ItemCreated

And the following code to change text in the context menu:

Protected Sub ContextHeaderMenu_ItemCreated(ByVal sender As Object, _
ByVal e As RadMenuEventArgs)

If (e.Item.Value = "ColumnsContainer") Then
e.Item.Text = "Show/Hide columns"

ElseIf (e.Item.Level = 2) AndAlso (TryCast(e.Item.Parent, RadMenuItem).Value = "ColumnsContainer") Then
If (e.Item.Value.EndsWith("ReceiverID")) Then
  e.Item.Text = "Source Receiver ID"
End If

End Sub

The part that changes the text to "Show/Hide columns" works but the one to change the text for items in "ColumnsContainer" doesn't.

It finds the item, sets the text but does not change when I run the code.

Any idea?

Thanks!

Hi,
I am using version 2015.1.401.40 of the ASP.NET controls for AJAX.

I am hiding the expand / collapse icon for mastertable rows where the detailed table has no rows.  I am also setting the detail table to visible false. I'm doing both of these in the DetailTableDataBind like so:

e.DetailTableView.Visible = False

parentItem("ExpandColumn").Controls(0).Visible = False

I want the users to be able to expand and collapse all rows that have child data, so I added this property to the RadGrid:  EnableHierarchyExpandAll="true"

However, that expands EVERY SINGLE ROW, even the rows where I've removed the expand / collapse button and set the detail table to invisible.

Question:  Is there any way I can expand ONLY the rows that have an expand / collapse icon (only the rows that actually have detail data)?

I've looked a bit at the javascript you all use _expandAll, but don't think I can implement what I want to do...

Thanks,

Hi,

i m giving the Telerik Spreadsheet a try, because i used the WPF and Silverlight one. But as far as i can see, there s still some features missing.

I see that the only way to "customize" and "interact" with the spreadsheet is via provider. So, if i want to get data from DB i overwrite the GetSheets() method, and if i want to Save i override the SaveToWorkbook method.

1) But, what if i want to interact with the spreadsheet without postback?

2) Is there any way from listening to the Cell OnChange event ? (even on the client side would be fine)

3) In the CellContextMenu there is a OnClientItemClicked event. Are there any more events runnable from the client side?

Thanks for your support

<telerik:GridCheckBoxColumn DataField="bitPhysical" HeaderText="Physical" UniqueName="bitPhysical" StringFalseValue="0" StringTrueValue="1" AllowFiltering="false"></telerik:GridCheckBoxColumn>

want this column to change and disable when check box is checked 

<telerik:GridDropDownColumn DropDownControlType="RadComboBox" EmptyListItemText="Select..." ListTextField="strHostName" ListValueField="intHostServerId" HeaderText="Host" UniqueName="HostName" FilterDelay="200" ShowFilterIcon="false"></telerik:GridDropDownColumn>               

also, would be able to do same with

<telerik:GridTemplateColumn HeaderText="Manufacturer" ItemStyle-Width="240px" UniqueName="ManufacturerName" FilterDelay="200" ShowFilterIcon="false">
                    <EditItemTemplate>
                        <telerik:RadDropDownList ID="radManufacturerDDL" runat="server" DefaultMessage="Select....." OnItemSelected="radManufacturerDDL_ItemSelected" AutoPostBack="true"></telerik:RadDropDownList>
                    </EditItemTemplate>
                </telerik:GridTemplateColumn>
                <telerik:GridTemplateColumn HeaderText="Model" ItemStyle-Width="240px" UniqueName="ModelName" FilterDelay="200" ShowFilterIcon="false">
                        <EditItemTemplate>

                            </telerik:RadDropDownList>
                        </EditItemTemplate>
                    </telerik:GridTemplateColumn> 

Please tell how i access this on client side.

I've tried using the various demo projects here - https://github.com/telerik/aspnet-sdk/tree/master/Scheduler/ExchangeCalendarSync

I'm getting this error:

Compiler Error Message: CS0508: 'ExchangeSchedulerProvider.GetAppointments(Telerik.Web.UI.RadScheduler)': return type must be 'System.Collections.Generic.IEnumerable<Telerik.Web.UI.Appointment>' to match overridden member 'Telerik.Web.UI.SchedulerProviderBase.GetAppointments(Telerik.Web.UI.RadScheduler)'

Source Error:

<telerik:RadButton runat="server" ID="testButton" OnClientClick="onclicktestbutton" />
<script type="text/javascript">
function onclicktestbutton(sender, args) {
// I don't use window.event (it is non-standard)
}
</script>

Where can I set the event object??
I wanted to do it like this:

<telerik:RadButton runat="server" ID="testButton" OnClientClick="onclicktestbutton(event)" />

but we all know you can't insert paragraph on a telerik client event attribute because it automatically includes in the function the parameters (sender, args).

Hi,

I am using version 2015.1.401.40 of the ASP.NET controls for AJAX.

I would think my question would be very common and easy to do.

I have a RadGrid with a MasterTableView and 1 DetailTable (GridTableView). I am using NeedDataSource for binding and it is all working fine.

Not all records in the master, have child records. For the rows that do not, I have hidden the expand/collapse button in the DetailTableDataBind event.

When I export to Excel, I want to expand all rows that contain a child record, so that those rows get exported.  I was doing that in DetailTableDataBind by setting every GridDataItem .Expanded = True.

ISSUE:

The problem with this is that it expands and exports the child rows that say "No Child Records".

Question: How can I NOT have it export the gridtableview, if there are no child records?

In the DetailTableDataBind, if there are no child records I set the DetailTableView.Visible = False, but my export still contains a blank row (which is better than the "No Child Records", but not perfect).

Thanks,
Brent
