Different data source for each column

Hello guys.

Is there a way to use a different source for each column is a list view?

For example, I have a listview with 5 columns, I'll receive 5 tables from the database (dataset). I would like to set each column to get data from each database table.

Does anyone know how I do this?

Column 1 Column 2 Column 3 Column 4 Column 5
userA, idA userB, idB userC, idC userD, idD userE, idE
userF, idF userG, idG   userH, idH userI, idI
userJ, idJ userK, idK userL, idL
userM, idM userN, idN
userO, idO userP, idP
userQ, idQ
userR, idR
userS, idS
userT, idT

How to change just radwindow border's opacity ?

Good morning,

I wonder If somebody could help me with my issue.

What I need to achieve is change RadWindow border's opacity (not background) as it's in this example:
http://demos.telerik.com/aspnet-ajax/controls/examples/integration/listviewsliderwindowrotator/defaultcs.aspx?product=listview

The problem is when I choose some standard skin, e.g. skin="Hay", then the RadWindow border is without opacity.

For futher info please check images in the attachment.

Please help me to solve this issue.

Best regards

Grid Expanding Beyond ContentPlaceHolder Div

OK here is the scenario. I have a website with a master page set up, and within one of the pages I am usin the grid control, which is set up to run off from partial postbacks. Everything works fine other then the control breaks out of the div that is set up to be a wrapper for the contentplaceholder, that is filled by the page with the grid. So to give you an idea here is a general idea of what i have below:

CSS:
#mainContentWrapper
{
     width:100%;
    //No height is set intentionally to allow for dynamic div growth
}

Master Page:

<div id="mainContentWrapper">
    <contentplaceholder></contentplaceholder1>
</div>

Data Page:
<contentplaceholder>
    <telerik:radgrid></telerik:ragrid>
</contentplaceholder>

The problem is as soon as you do anything like change record display size from the client, it breaks out of the mainContentWrapper div instead of the forcing the div to expand like it should. This would work with any other functionality that isnt using the telerik controls so my assumption is that are some point in rendering the grid control is changed to be absolute and thus is placed above the div and will not adjust its size?

Nested combobox and treeview with checkbox CheckedChanged event not firing

Hi,

We have a RadTreeView and inside its NodeTemplate we have a RadComboBox. In the Itemtemplate of RadComboBox we have a checkbox. AutoPostback property of checkbox is set to true but when I check the checkbox the page refreshes (a postback occurs but not an Ajax postback although RadTreeView is ajaxified using RadAjaxManager) but CheckedChanged event doesn't fire.

I set the data for RadTreeView on Page Load and Node Expand functions. And I set the data for RadComboBox on ItemsRequested method of RadComboBox since LoadOnDemand is set to true.

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanelDefault" runat="server">

</telerik:RadAjaxLoadingPanel>

<fieldset>

<div>

<telerik:RadTreeView ID="TreeViewUnits" runat="server"

<telerik:RadComboBox runat="server" ID="ComboTags" Height="190px" Width="420px" EnableLoadOnDemand="true"

HighlightTemplatedItems="true" OnDataBound="ComboTags_DataBound" OnItemDataBound="ComboTags_ItemDataBound"

OnItemsRequested="ComboTags_ItemsRequested">

<HeaderTemplate>

<ul>

RadWindow basics

Hello I am new to telerik radwindows so I may not be asking the question the right way...pls forgive.
But I have requirements to update our application to allow toggling of clients/people. The current application (I'm told uses "scope" to designate when a user selects a client then maps clientid, name, etc to session memory for updates to db. I need to update application to allow for a main page where listing all clients and allow for user to select a client in a radwindow with the scope/memory data, do db updates, then be able to minimize that radwindow and select another clientid and updates......more same

I think I would just call radwindow and give it the clientid as the name. ? Right? Also how do I load the "scope" and memory to toggle and make sure my radwindow has the right client info when I do db updates?

Any help is appreciated

Main Window/User home page
Left side Right side content display
Navigator Panel Client ID, Name of Client, etc

Client 1
Client 2
Client 3

RadGrid Grouping very slow

Hi,

Just started using your RadGrid for ASP.net here at work and have a table with about 500,000 rows that I am testing with. Sorting/Paging/Filtering all works fine and I am able to build a custom linq query to only return the rows i need to be displayed...but, I'm not having any luck doing that with grouping as I need to return the entire resultset for radgrid to group correctly.

As the rows increase in the database table, so does the time it takes for the page to load when grouped or when performing any type of grouping, i'm using the following code for testing, and currenly have PageSize set to 10, as per the default.

Protected Sub RadGrid1_NeedDataSource(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles RadGrid1.NeedDataSource

Dim db As New TrackerDataContext

db.Log = New System.Diagnostics.DebuggerWriter

Dim query = From p In db.posts

Where p.parentid = 0

Select p

If String.IsNullOrWhiteSpace(RadGrid1.MasterTableView.FilterExpression) = False Then

query = query.Where(RadGrid1.MasterTableView.FilterExpression)

End If

For Each exp As GridSortExpression In RadGrid1.MasterTableView.SortExpressions

query = query.OrderBy(String.Format("{0} {1}", exp.FieldName, exp.SortOrder.ToString))

Next

Dim start As Integer = RadGrid1.CurrentPageIndex * RadGrid1.PageSize

Dim max As Integer = RadGrid1.PageSize

RadGrid1.AllowCustomPaging = True

'we always need count

RadGrid1.VirtualItemCount = query.Count

If isGrouping Or RadGrid1.MasterTableView.GroupByExpressions.Count > 0 Then

start = 0

max = RadGrid1.VirtualItemCount

RadGrid1.AllowCustomPaging = False

End If

RadGrid1.DataSource = query.Skip(start).Take(max)

End

Sub

Private isGrouping As Boolean = False

Protected Sub RadGrid1_GroupsChanging(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridGroupsChangingEventArgs) Handles RadGrid1.GroupsChanging

isGrouping = True

If e.Action = GridGroupsChangingAction.Ungroup AndAlso RadGrid1.MasterTableView.GroupByExpressions.Count = 1 Then

isGrouping = False

End If

End Sub

Is there any way to improve the performance?

Take Care
