how to save results of batch editing, all rows, all cells

Hi,
In reading the documentation here:

http://www.telerik.com/help/aspnet-ajax/grid-batch-editing.html

I see this:
CautionWhen setting the EditMode to Batch multi-row editing is not supported as only one editor is initialized for a given column(for performance purposes).

This caution would seem to defeat the purpose of batch (Excel-like) editing.

I'm trying to find a way to save the new values for all rows and all cells that have the red triangle on them as the result of batch editing. As it is now, I can only retrieve the values from the cell that is currently having an edit made.

Here is the start of my code. Perhaps it's not firing on the proper event.

Protected Sub RadGrid1_ItemCommand(sender As Object, e As Telerik.Web.UI.GridCommandEventArgs) Handles RadGrid1.UpdateCommand

Dim argument As Telerik.Web.UI.GridBatchEditingEventArgument = TryCast(e.CommandArgument, Telerik.Web.UI.GridBatchEditingEventArgument)

Dim oldValues As Hashtable = argument.OldValues

Dim newValues As Hashtable = argument.NewValues

Thanks in advance.

Inserting image and text from the code behind

Hi,

I would like to insert an image and text from the code behind once user has uploaded a photo with ability to re-position both (inserted image and text).

Currently I have followed this Demo to achieve uploaded image and showing into rad image editor correctly but same time i would like to insert an overlay image (e.g. water mark/company logo) and some text before showing it into rad image editor from the code behind (or may be from the client side - if possible).

Also both (inserted image and text) should be allowed to re-position once it is shown in rad image editor.

Any help would be really appreciated.

Regards,

Chintan

Cancel Running Ajax Request

Hello,

I'm working on a project with controls that are updated by Ajax.

The project requirement is that the user may cancel a running request by clicking a button, and also fire the cancel event to the server.

How can I do this?

Thanks,
Daniel.

Empty Field Alias in Group By Expression

Is there any reason you can't do an empty field alias in a group by expression? This seems like a very common thing to do as the field name clutters up the group by caption. Is there any clean way to do this? Also how do i put an alias on the actual field name that shows up in the group by header. I tried adding it after the field name as you do for the first field in the expression, but this did not seem to have any effect.

Thanks!
Levi

Deduplicate on a column fails

I encouter a strange behavior when I try to de-duplicate a grid with this code:

Protected Sub dtgProducts_ItemCreated(sender As Object, e As GridItemEventArgs)

If (TypeOf (e.Item) Is GridDataItem) Then

Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)

Response.Write(ProductMem & "-" & item.GetDataKeyValue("ProductCode") & "<br>")

If item.GetDataKeyValue("ProductCode") = ProductMem Then 'ontdubbelen voor de zoekfunctie

item.Display = False

End If

ProductMem = item.GetDataKeyValue("ProductCode")

End If

End Sub

With four data items with ProductCode 106901AS404, the output is:

106901AS404-106901AS404
106901AS404-106901AS404
106901AS404-106901AS404
106901AS404-106901AS404

So how could ProductMem already be set on '106901AS404' in the first loop when no preceding item exists?

Please reply soonest, this is an urgent one...

Thanks,

Marc

RadMap refreshing shape layer in ajaxpanel

Hi

The problem I am having is that when I put a RadAjaxPanel around my RadMap a postback to update the RadClientDataSource needs to be clicked twice in order for the select url to be called. It works fine if I remove the ajax panel.

<telerik:RadAjaxPanel runat="server">

<telerik:RadTabStrip ID="connectionsTabStrip" runat="server" MultiPageID="connectionsMultiPage">

<Tabs>

<telerik:RadTab Text="Map" PageViewID="mapPageView" />

</Tabs>

</telerik:RadTabStrip>

<telerik:RadMultiPage ID="connectionsMultiPage" runat="server">

<telerik:RadPageView ID="mapPageView" runat="server">

<telerik:RadClientDataSource runat="server" ID="tripDataSource" AutoSync="true">

<DataSource>

<WebServiceDataSourceSettings ServiceType="GeoJSON" />

</DataSource>

</telerik:RadClientDataSource>

<telerik:RadButton ID="button" runat="server" Text="View" OnClick="button_Click" />

<telerik:RadMap runat="server" ID="tripMap">

<LayersCollection>

<telerik:MapLayer></telerik:MapLayer>

<telerik:MapLayer Type="Shape" ClientDataSourceID="tripDataSource">

<StyleSettings>

<StrokeSettings Color="#ffffff" Width="10" />

</StyleSettings>

</telerik:MapLayer>

</LayersCollection>

<DataBindings>

<MarkerBinding

DataShapeField="shape"

DataTitleField="title"

DataLocationLatitudeField="locationLatitude"

DataLocationLongitudeField="locationLongitude"

DataTooltipTemplateField="tooltipTemplate" />

</DataBindings>

<CenterSettings Latitude="-32.962926" Longitude="151.699727"/>

</telerik:RadMap>

</telerik:RadPageView>

</telerik:RadMultiPage>

</div>

<uc1:ExceptionArea runat="server" ID="ExceptionArea" />

</telerik:RadAjaxPanel>

I have some code behind on the button click "button_Click"

tripDataSource.DataSource.WebServiceDataSourceSettings.Select.Url = "/Data/GetJsonTrip.aspx";

tripDataSource.DataBind();

tripMap.DataSource = GetMarkers();

tripMap.DataBind();

If I put a break point in GetJsonTrip.aspx I can see it only gets called, on the first click, but does get called on every click after that.

If I set WebServiceDataSourceSettings.Select.Url in a partial post back, why does the indicated URL not get called after the first postback?

Thanks for any help

Custom select/edit function

Select button example

I am looking to do something similar to this example but instead, I want a button or link in a column to fire an event which opens up the record for editing.

Clicking the row fires a selected index changed which does something else.

The closest thing I have found is something like this:

Event DataGridView1ButtonClick(sender As DataGridView, e As DataGridViewCellEventArgs)

Private Sub DataGridView1_CellContentClick(sender As System.Object, e As DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick

Dim senderGrid = DirectCast(sender, DataGridView)

If TypeOf senderGrid.Columns(e.ColumnIndex) Is DataGridViewButtonColumn AndAlso e.RowIndex >= 0 Then

RaiseEvent DataGridView1ButtonClick(senderGrid, e)

End If

End Sub

Is this possible with the RadGrid?
