WAI-ARIA: How can I assign access keys to PanelBar control?

Hi,

I'm working on a legacy ASP.NET WebForms project and I am to add accessibility to the project.

My predecessor already tried to add accessibility by manually assigning an access key to the AccessKey property of some of the PanelBar's RadPanelItemCollection elements (see attachment #1).

Lose changed values on clicking asp button

Hello,
I am using a RadGrid with multiple columns which can be edited (BatchEdit like excel).

<telerik:RadGrid RenderMode="Lightweight" ID="RadGrid1" runat="server" AutoGenerateColumns="False"GridLines="Both"OnNeedDataSource="RadGrid1_NeedDataSource" AllowAutomaticInserts="True" AllowAutomaticUpdates="True"AllowAutomaticDeletes="True">

<ItemStyle Wrap="false" />

<MasterTableView TableLayout="Fixed" NoMasterRecordsText="" ShowFooter="true" EditMode="Batch">

...

</MasterTableView>

</telerik:RadGrid>

Datasource of RadGrid is ObjectDataSource

<asp:ObjectDataSource ID="TestSource" runat="server" TypeName="TestClass" SelectMethod="GetAllItems">

<UpdateParameters>

<asp:Parameter Name="Name" Type="String" />

<asp:Parameter Name="LastName" Type="String" />

<asp:Parameter Name="BirthData" Type="DateTime" />

</UpdateParameters>

</asp:ObjectDataSource>

On OnNeedDataSource event I'm setting Id of ObjectDataSource to RadGrid.DataSourceId.

protected void RadGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

RadGrid1.DataSourceID = "TestSource";

}

In current Page I have also button "Send email" send rad gird inserted values.
<asp:Button ID="SendEmail" OnClick="SendEmail_Click" Text="Send" runat="server" />

Problem is that on SendEmail_Click DataSource is null. But I want to get newly changed DataSource.

protected void SendEmail_Click(object sender, EventArgs e)

{

RadGrid1.Rebind();

// RadGrid1.Datasource is null

}

How I can solve this problem?

Thanks,

Daler

Radgrid inside Editform Template of Parent Grid causes Parent Grid to rebind.

I have an RadGrid with an Editform template that contains a RadAjaxPanel control with a sub-gird inside panel. I am using the RadAjaxPanel to help eliminate the page refresh when performing updates to the data inside the editform template. I use a RadAjaxLoadingPanel with all default values so that when the sub-grid is updated the loading image shows and the whole page will not refresh. However, I noticed that if I refresh or rebind the sub-grid it causes the parent grid to refresh as well. So the setup looks something like this.

<telerik:RadGrid ID="MyParentGrid ... >
   {Databound Columns}
   ...
<EditFormSettings EditFormType="Template" EditColumn-HeaderButtonType="LinkButton">
      <EditColumn UniqueName="EditCommandColumn1" FilterControlAltText="Filter EditCommandColumn1 column"></EditColumn>
                <FormTemplate>
   <telerik:RadAjaxPanel ID="EditArea" runat="server" Visible='<%# IIf((TypeOf(Container) is GridEditFormInsertItem), "false", "true") %>' BorderStyle="Solid" BorderWidth="1px" LoadingPanelID="RadAjaxLoadingPanel1">

                                           <telerik:RadGrid ID="MyChildGrid" ... >
                                           </telerik:RadGrid>

                   </telerik:RadAjaxPanel...>
                    <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Default">
                    </telerik:RadAjaxLoadingPanel>
                </FormTemplate>
         </EditFormSettings>
</telerik:RadGrid>

Is there something I need to do to isolate the update of the sub-grid from the parent grid? Do I need an AjaxManager inside the EditForm Template?

Thanks in Advance,

Jeff

Show several pagination pages but only query what the user see

Hello,

I have a problem where I pull data from a huge database (over 140 000 entries) and have taken care to do my own pagination to limit loading time for my users.

Basically, on pagination changes (next, prev, click on number etc.) I query my own 20 rows (which is pagesize) to fill up only what the user see and not pull tens of thousands of rows each time which would slow down the user's experience.

So my problem is, if I do it this way, my table only shows my 20 rows and not whats available to the user.

I have a line in my codebehind that returns the number of results I would like to tell RadGrid is available:

var querySize = bllUsNet.ObtenirTout().Count;

Is there a way to "Trick" Radgrid into thinking there is that many entries but only return 20 ?

If anyone has an idea of a better title for this thread, I had a hard time to find one :)

Thanks

RadAjaxManager with multiple user control ajax request handlers?

So, I have a page with multiple user controls. There is a RadAjaxManager on the page. Each user control needs to make ajaxRequests from javascript, and I would like each control to handle that itself. Is this possible?

So, for instance, I have control1 with the following in its code behind:

protected void Page_Load(object sender, System.EventArgs e)

{

RadAjaxManager manager = RadAjaxManager.GetCurrent(Page);

manager.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(Control1_AjaxRequest);

}

and control2 with

protected void Page_Load(object sender, System.EventArgs e)

{

RadAjaxManager manager = RadAjaxManager.GetCurrent(Page);

manager.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(Control2_AjaxRequest);

}

and in javascript, control1 does

$find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest(dataString);

and I end up in Control2_AjaxRequest rather than Control1_AjaxRequest.

Is what I'm trying to do possible? If so, how? I'm currently trying to do this by adding a RadAjaxPanel to each control and invoking ajaxRequest on it, but I'm running into some code block issues with this that weren't there with RadAjaxManager.

Postback problem in custom advanced form

Hi!
I'm using the radscheduler with a custom advanced form.
Both the advanced form and the page containing it have EnableViewState to true but I'm still having post back issues.
When a control in the advanced form fires a postback, all data binded to the advanced form is cleared and the state of the controls are reset.

How do you prevent this?
thanks!

Add target="_Blank" to NavigateURL

Hello,

I have the RadImageGallery implemented using the following:

<telerik:RadImageGallery ID="ImageGallery" RenderMode="Auto" runat="server" LoopItems="true" ShowLoadingPanel="true" AllowPaging="false" DisplayAreaMode="Image" OnNeedDataSource="ImageGallery_NeedDataSource" DataTitleField="ImageTitle" DataDescriptionField="ImageDescription" DataImageField="ImageURL"></telerik:RadImageGallery>

the Code behind is like this:

Protected Sub ImageGallery_ItemDataBound(sender As Object, e As ImageGalleryItemEventArgs) Handles ImageGallery.ItemDataBound Dim item As ImageGalleryItem = TryCast(e.Item, ImageGalleryItem)

Dim db As New DBCorrDefense.DBDCDataContext()

For Each item In ImageGallery.Items

Dim EmData = db.CDSP_Get_URLByImageTitle(item.Title).FirstOrDefault

If EmData Is Nothing Then

Else

item.NavigateUrl = EmData.URL

End If

Next

db.Dispose()

db = Nothing

End Sub

Protected Sub ImageGallery_NeedDataSource(sender As Object, e As Telerik.Web.UI.ImageGalleryNeedDataSourceEventArgs) Handles ImageGallery.NeedDataSource

Dim db As New DBCorrDefense.DBDCDataContext()

ImageGallery.DataSource = db.CDSP_Get_AllSlides()

End Sub

How is it possible to allow the NavigateURL to open in a new blank page when i click on the ImageItem? currently it is opening in the same page

Thanks

ImageGallery
