Greetings,

The TagCloud control automatically adds a title attribute to each tag which automatically generates a ToolTip, is there anyway to disable this for the TagCloud control?

Thank you.

Value="RadComboBoxItem3" />

Any idea ?

RadAsyncUpload: Sys.WebForms.PageRequestManagerServerErrorException

Hi,

I am adding the RadAsyncUpload user control both in asp:GridView and page in a single file. After selecting a file and click on Upload I am getting the following error.

---------------------------
Message from webpage
---------------------------
Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500
---------------------------
OK
---------------------------

The uploaded file is saved into App_Data folder (like nkdeutts.hpj), but OnFileUploaded event is not firing. Before this event is fired I am getting the above error.

If I include the user control only in grid view or only in the page, it is working fine. If I use it in both the places, I am getting the error. Please help me in resolving this error as it is important for me to have the control in both the places.

Thanks.

[Solved] Designing the Master and Detail

Hello Telerik,

I build the grid columns and set up the relationships in aspx and the data source is set in code-behind. The gird changes depending on a node selection which sends in a ID to filter out the master grid, which in turn filters out the detail grid based off the relationship.

Here is the grid in aspx:

<telerik:RadGrid runat="server" ID="RadGridMemberBoardPosition" Width="350px" Height="460px" AutoGenerateColumns="false" >

<MasterTableView DataKeyNames="MemberId" >

<Columns>

<telerik:GridClientSelectColumn ItemStyle-Width="10%"/>

<telerik:GridBoundColumn DataField="Name" DataType="System.String" HeaderText="Name" UniqueName="Name" />

</Columns>

<DetailTables >

<telerik:GridTableView DataKeyNames="MemberId">

<Columns>

<telerik:GridBoundColumn DataField="FullName" DataType="System.String" HeaderText="FullName" UniqueName="FullName" />

<telerik:GridBoundColumn DataField="EmailAddress" DataType="System.String" HeaderText="EmailAddress" UniqueName="EmailAddress" />

</Columns>

</telerik:GridTableView>

</DetailTables>

<ParentTableRelation>

<telerik:GridRelationFields DetailKeyField="MemberId" MasterKeyField="MemberId" />

</ParentTableRelation>

</MasterTableView>

<ClientSettings Selecting-AllowRowSelect="true" Scrolling-AllowScroll="true" />

</telerik:RadGrid>

Now in code behind i change the data with the node being selected in a TreeView on the page.

Protected Sub RadTreeViewGroups_NodeClick(sender As Object, e As Telerik.Web.UI.RadTreeNodeEventArgs) Handles RadTreeViewGroups.NodeClick

If Me.m_cMyManager Is Nothing Then

Me.m_cMyManager = New cMyManager

End If

' get the board positions and the members for those postions - hierarchical grid

Me.RadGridMemberBoardPosition.DataSource = Me.GetGroupBoardPositionDT(Me.m_cMyManager, e.Node.Attributes("GroupId"))

Me.RadGridMemberBoardPosition.Rebind()

End Sub

This code works fine for filling in the master table with the appropriate records. Now when a record is expanded by clicking its arrow - showing the detail grid it is always nothing.

This is the data source for the detail - setup in the page load.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Me.m_cMyManager Is Nothing Then

Me.m_cMyManager = New cMyManager

End If

' get the sql datasource for the detail of the datagrid

Dim mySqlDataSource As New SqlDataSource("System.Data.SqlClient", Me.m_cMyManager.MyDb.ConnectionString(), Me.GetBoardPositionMembersQuery(Me.m_cMyManager))

' add the parameters

Dim myParameter As New UI.WebControls.Parameter("MemberId", DbType.Int64)

mySqlDataSource.SelectParameters.Add(myParameter)

Me.RadGridMemberBoardPosition.MasterTableView.DetailTables(0).DataSource = mySqlDataSource

End Sub

I also tried to put it in the Handles RadGridMemberBoardPosition.DetailTableDataBind event, but it still failed to show the records related to the master table. This is a little different than your example http://demos.telerik.com/aspnet-ajax/grid/examples/programming/hierarchy/defaultvb.aspx so I was wondering if it should all be in the code-behind. Also, if this will work in my scenario with a node changing the data source of a master and detail tables at run-time.

Can you shed some light on this?

Thanks!
SDI

radGrid does not show values

Hello! I'm starting to use this component and I have some doubts. I have on my page the following controls:

RadScriptManager1
RadAjaxManager1
RadAjaxLoadingPanel1

RadTabStrip1 // Filters for the query
RadMultiPage11
- RadComboBox111, RadComboBox112 and RadComboBox113.
RadMultiPage12
- RadTextBox121, RadDatePicker122 and RadButton.

RadTabStrip2 // Query values from dataTable
RadMultiPage21
- RadHtmlChart211
RadMultiPage22
- RadGrid221

------------------------------------------------------
Events:

1. Select filters;
2. I press the radButton;
3. Make the query;
4. I carry the dataTable;
5. Link the dataTable to the radGrid and radHtmlChart.

Problem:

The radGrid not showing values. Only when I group a column or orderer a column alphabetically, the values appear. Are missing some event handler? This is the right way?

Thanks!

Combo Box very slow

I replaced native DDL with Combobox:

<telerik:RadComboBox ID="ddlPatientSuchwort2" Runat="server" Culture="de-DE"

DataSourceID="sqlWinacsPatientSuchwort" DataTextField="Suchwort"

DataValueField="PublicNummer" AutoPostBack="True"

EnableAutomaticLoadOnDemand="True"

onselectedindexchanged="ddlPatientSuchwort2_SelectedIndexChanged"

filter="StartsWith" EmptyMessage="Wähle Patient Name" Skin="WebBlue" >

</telerik:RadComboBox>

Data source is stored procedure which returns about 8000 rows in format ID, Name

Now performance is terrible, before result was displayed immediately, now even on DEV machine I need to wait few seconds, but in prod environment event more than 5 secs. At the current stage system is almost not usable. Any ideas how Ican improve performance?
