Is there any way to have radgrid Hierarchy data table expand arrow ONLY shows when there are child data records there? DO NOT show if no child data.

So the user don't have to click the arrow to open the child data if no child data exists.

Thanks,

Paghing of RadGriid which is in usercontrol

I've got radgrid control which is inside a user ascx file. I'm doing this because I should use radgrid in mvc(so there is no other way - is should wrap it in user control)

<%@ Control Language="C#" AutoEventWireup="true" Inherits="MvcBeaWeb.ProductsShowTile" CodeFile="ProductsShowTile.ascx.cs" %><

br><%@ Import Namespace="MvcBeaWeb" %> <%@ Register Assembly="Telerik.Web.UI" TagPrefix="telerik" Namespace="Telerik.Web.UI" %> <%@ Register TagPrefix="qsf" Namespace="Telerik.QuickStart" %> <form id="form_TilesShow" runat="server"> <telerik:RadScriptManager ID="RadScriptManager1" runat="server" > </telerik:RadScriptManager> <telerik:RadAjaxPanel runat="server" ID="RadAjaxPanelTilesShow" LoadingPanelID="RadAjaxLoadingPanelTilesShow" HorizontalAlign="Center" Width="472px" > <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"> <AjaxSettings> <telerik:AjaxSetting AjaxControlID="radGrid1"> <UpdatedControls> <telerik:AjaxUpdatedControl ControlID="radGrid1" /> </UpdatedControls> </telerik:AjaxSetting> </AjaxSettings> </telerik:RadAjaxManager> <div class="mainHolder"> <div class="qsf-ib tileListHolder"> <telerik:RadGrid runat="server" OnNeedDataSource="RadGrid1_NeedDataSource" ID="RadGrid1" AutoGenerateColumns="false" AllowPaging="True" PageSize="3" OnPageIndexChanged="RadGrid2PageIndexChanged" > <PagerStyle Mode="NextPrevAndNumeric" Position="TopAndBottom" PageSizeControlType="RadComboBox"></PagerStyle> <MasterTableView> <Columns> <telerik:GridBoundColumn DataField="ArticlegroupID" HeaderText="idddd" UniqueName="groupID"> </telerik:GridBoundColumn> <telerik:GridBoundColumn DataField="SpecialWord" HeaderText="ProductDescription" UniqueName="ProductDescr" > </telerik:GridBoundColumn> <telerik:GridImageColumn DataType="System.String" DataImageUrlFields="ImageFile" AlternateText="Customer image" <br

>                                            ImageAlign="Middle" ImageHeight="100px" ImageWidth="82px" HeaderText="Image Column"><

br> </telerik:GridImageColumn> </Columns> </MasterTableView> </telerik:RadGrid> </div> </div> </telerik:RadAjaxPanel> </form>

As I want to use paging I have set allow pagin to true; In my ascx.cs file I only have Onneeddata source function in which I bind the datasource of the grid. The strangest thing is that it showas me - 3 items of 4/ page1 but nothing happens when I click the second page. There is not even a javascript error

nam

espace MvcBeaWeb {  public partial class ProductsShowTile: System.Web.Mvc.ViewUserControl {  protected void RadGrid1_NeedDataSource(object

sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)<br>    {<br>           <br><br>            RadGrid p_RadIconProducts =

this.FindControl("RadGrid1") as RadGrid; List<WebServiceBeaMenu> radTileIcon = new

List<WebServiceBeaMenu>();<br>            radTileIcon = MvcBeaDAL.WebServiceBea.GetArticle(p_menuID, p_articlegroupID, p_id).ToList();<br>            p_RadIconProducts.DataSource = radTileIcon;<br>      <br>    }<br>

I'm starting to wonder if I would be able to use paging in mvc as here in mvc there is no postback and I would be happy if you advise me how to overcome this probklem

Can't read server-side setted values in js pageLoad

Hi guys,

I've an aspx web form with a radAjaxManager, which handles some autopostback input and refreshes a custom ascx

In the ascx there is some hiddenField which is setted server side, depending on aspx' input values, and some javascript

I want to execute some javascript function depending on the hiddenField value, so I'm checking it in a js pageLoad event

The problem is, despite the fact html values are updated (I can see it with firebug), the pageLoad sees always the same value

If I do something simple as alert($(hiddenField).val()) I see always the original, entire-page-loaded value, and not the ajax updated value

What's wrong? Some clue?

Thank you,

Martino

Issue in adding fields using dimension attribute checkbox

Hello,

I'm using OLAP connection to pivot grid with version [2014 Q1 Sp1]. Fallowing steps illustrate the issue I experience.

1) Add dimension attribute to a row or column field using the dimension attribute's check-box.
2) Hit update button
3) notice that attributes data doesn't show up.

Further, Same data field is repeated when dimension attribute check-box is used.

Adding attributes using context menu works fine.

Thanks and Regards,
Yohan

Save/Load PivotGrid State in MSSQL database

Hello,

I'm currently trying to save and load the current selected state of pivot grid in MSSQL database. I've managed to get mentioned functionality working although noticed that Persistence Framework fail to load the persisted view on get request (fields not getting added to grid when loading the persisted view on get request), It only work on post request. Is this a limitation of Persistence Framework? is this achievable? I have attached my sample project (rename the extension as rar).

Steps to reproduce :

1) set some fields on pivot grid using configuration panel.
2) persist the selected view using save button.
3) press "F5" and refresh the browser.
4) Press "load" button to reload the persisted view.

Thanks and Regards,
Yohan

Web Farm RadAsyncUpload

Hi,

If you look here, you will see that Lynne had to make changes to her application to get radasyncupload working in a web farm environment:
http://www.telerik.com/forums/radasyncupload-in-web-farm

She says she had to "create a separate application pool for the web application. Change the Identity on the application pool from ApplicationPoolIdentity to LocalSystem. Change web application to use the new application pool. "

This really worries me. I do not want to touch my app pool identity, and I still need the radasyncupload to work in a web farm environment.

Is it possible that the UseApplicationPoolImpersonation property has been introduced to fix this issue? Can anyone confirm that the radasyncupload control will work properly, out of the box, in a web farm environment, when the Temporary Folder is pointed through the web.config to a shared location that everyone has full access to?

Thanks

Daniel

Cannot find a column with UniqueName 'FileID' on my TemplateColumn

Hi, I have a template column titled 'FileID' and am trying to access it. Unfortunately whenever it comes across a template column, it will error out saying that FileID is not a column.

ASPX:

<telerik:GridTemplateColumn DataField="FileID" HeaderText="File / Link" HeaderStyle-Width="55px" SortExpression="FileID" HeaderStyle-ForeColor="White" AllowFiltering="false" ItemStyle-Width="20%" ItemStyle-Wrap="true" ShowSortIcon="false">

<ItemTemplate>

<asp:HyperLink ID="hlLink" runat="server" Target="_blank" Visible="false"></asp:HyperLink>

</ItemTemplate>

</telerik:GridTemplateColumn>

From this you can see that my GridTemplateColumn's DataField is named "FileID"

VB.NET:

For Each col In dg.Columns

If (col.GetType() Is GetType(Telerik.Web.UI.GridBoundColumn)) Then

If col.HeaderText = ColumnName Then

If HideOrShow Then

dg.MasterTableView.GetColumn(col.DataField).Display = True

Else

dg.MasterTableView.GetColumn(col.DataField).Display = False

End If

Else

If (col.GetType() Is GetType(Telerik.Web.UI.GridTemplateColumn)) Then

If HideOrShow Then

dg.MasterTableView.GetColumn(col.DataField).Display = True

Else

dg.MasterTableView.GetColumn(col.DataField).Display = False

End If

Next

And this is what throws the error: dg.MasterTableView.GetColumn(col.DataField).Display = True underneath the TemplateColumn part.

Did I not name the column correctly? I thought DataField was what I used, and it works on the rest of the BoundColumns. Can I get some pointers here?

Thanks!
