Programitically set a "ClientSelectColumn" to "checked"

I have the following in my ASPX page
   <Columns>
    <telerik:GridClientSelectColumn Reorderable="False" UniqueName="ClientSelectColumn">
    </telerik:GridClientSelectColumn>
    <telerik:GridTemplateColumn HeaderText="Units On Order" UniqueName="unqUnitsOnOrder" ItemStyle-HorizontalAlign="Right">
     <ItemTemplate>
      <asp:TextBox ID="txtUnitsOnOrder" MaxLength="5" runat="server" Width="60px" Text='<%# String.Format("{0:#,##0}", DataBinder.Eval(Container.DataItem,"UnitsOnOrder")) %>' />
     </ItemTemplate>
     <EditItemTemplate>
      <asp:TextBox ID="txtUnitsOnOrderUpd" runat="server" Width="60px" Text='<%# DataBinder.Eval(Container.DataItem,"UnitsOnOrder") %>' />
     </EditItemTemplate>
    </telerik:GridTemplateColumn>
    </Columns>

I use the following to modify a grid page at runtime

   Public Sub radGrid_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs)
        If e.Item.ItemType = GridItemType.Item OrElse e.Item.ItemType = GridItemType.AlternatingItem Then
            Dim txtUnitsOnOrder As TextBox = DirectCast(e.Item.FindControl("txtUnitsOnOrder"), TextBox)
            txtUnitsOnOrder.Style("text-align") = "right" '
         End If

End Sub

What code do I add to have a specific "ClientSelectColumn" "checked" when a grid page is displayed?

[Solved] Check a ClientSelectColumn in codebehind

My aspx page has

    <telerik:GridClientSelectColumn Reorderable="False" UniqueName="ClientSelectColumn">
              <HeaderStyle Width="20px"></HeaderStyle>
    </telerik:GridClientSelectColumn>

In my code behind, I want to initialy check some rows. How do I code this?

The following code does not produce an error, but nothing is checed when the page is displayed
(I've tried this the following events: ItemDataBound, ItemCommand, and PreRender

Dim chkClientSelectColumn As CheckBox = DirectCast(item.FindControl("ClientSelectColumnSelectCheckBox"), CheckBox)
chkClientSelectColumn.Checked = True

Sort disabled after heading text localized

I am using using the ItemCreated event handler to change to column heading based on a specified language code. The default is english and the english headings are coded in the grid definition. I use the following code to set the text.

    Protected Sub RadGrid1_ItemCreated(ByVal sender As Object, ByVal e As GridItemEventArgs) Handles RadGrid1.ItemCreated
        If TypeOf e.Item Is GridHeaderItem Then
            Dim headerItem As GridHeaderItem = CType(e.Item, GridHeaderItem)
            If lstLanguage.Text <> "en" Then
                Dim m As New Misc()
                Dim strText As String = m.GetText(Session("strDataConnectString"), 16, lstLanguage.Text)
                headerItem("UserName").Text = strText
                strText = m.GetText(Session("strDataConnectString"), 17, lstLanguage.Text)
                headerItem("Subject").Text = strText
                strText = m.GetText(Session("strDataConnectString"), 18, lstLanguage.Text)
                headerItem("UpdateDateTime").Text = strText
            End If
        End If
    End Sub

My problem is that once the heading text is changed, sorting is no longer active for those columns. Only if the headers are in english (the default) can I sort. I have searched for 2 hours trying to find posts regarding this and could not find any. Thanks in advance for your help.

[Solved] radWindow tooltip style popup under grid cell

I am trying to get a small radWindow to popup under a grid cell when the mouse is over the cell. I can get this to work, but I am having trouble positioning the popup where I want it. Here is the client side code I am using.

    
            function rgCase_onRowCreated(sender, eventArgs) {  
        
              var dataItem = eventArgs.get_gridDataItem();  
        
              dataItem._element.cells[5].onmouseover = function() {  
        
                var CaseID = eventArgs.getDataKeyValue("CaseID");  
        
                var oManager = GetRadWindowManager();  
        
                var oWindow = oManager.getWindowByName("rwCaseDetails");  
        
                oWindow.set_offsetElementID(dataItem._element.cells[5].uniqueID);  
        
                oManager.open("CaseDetails.aspx?CaseID=" + CaseID, "rwCaseDetails");  
        
              };  
        
              dataItem._element.cells[5].onmouseout = function() {  
        
                var oManager = GetRadWindowManager();  
        
                oManager.closeActiveWindow();  
        
              };  
        
            }

This works somewhat, the first cell I hover over gets the popup in the correct place, but it pops up in this same place for each subsequent cell that I hover over. Here is the definition of the radWindow.

    
            <telerik:RadWindow ID="rwCaseDetails" runat="server" Behavior="None" Behaviors="None" InitialBehavior="None" NavigateUrl="CaseDetails.aspx" ReloadOnShow="True" ShowContentDuringLoad="False" Style="display: none;" Left="-110px" Top="20px" Width="220px" Height="150px" VisibleStatusbar="False" DestroyOnClose="False" EnableViewState="False" KeepInScreenBounds="True" VisibleTitlebar="False">  
        
            </telerik:RadWindow>

Any ideas on how to get this to work, or on an aternative way to accomplish it?

Thank you,

John

Detecting DragEnd in treeview

Hi,

I've looked around, but I can't find the answer to this, so here gos. Does anybody know how to detect that a drag operation has been ended, in the case where the ending isn't caused by dropping the node? The two cases where I can get this to happen are (1) dragging the node outside the bounds of the browser window and (2) pressing escape while dragging.

I am using the client side events OnClientNodeDragging and OnClientNodeDropping, but OnClientNodeDropping doesn't fire in the above two cases, which seems correct since you haven't dropped the node.

I need to know when the drag has ended, whether dropped or otherwise, so that I can revert the selected node back to whatever it was before the drag began.

Thanks in advance

I have a dataset that essentially flattens a couple of relational tables (Biz Segments, Biz Units, and Facilities).

The dataset look like:

BizSegmentID,BizSegmentName,BizUnitID,BizUnitName,FacilityID,FaciliyName
1,SegA,1,UnitA,1,FacilityA
1,SegA,1,UnitA,2,FacilityB
1,SegA,2,UnitB,3,FacilityC
1,SegA,2,UnitB,4,FacilityD
2,SegB,3,UnitC,5,FacilityE
2,SegB,3,UnitC,6,FacilityF

I want the tree to look like:

-SegA
    --UnitA
        ---FacilityA
        ---FacilityB
    --UnitB
        ---FacilityC
        ---FacilityD
-SegB
    --UnitC
        ---FacilityE
        ---FacilityF

What is the best way to go about binding the tree to this type of dataset?

Thanks in advance,
Gene.

[Solved] Plain Text

I am using the Editor as an email template editor. The users have the ability to create html or plain text emails. The problem is when I use the .Text property I am not getting the carriage returns or line feeds. Is there a different property I need to be using or setting just to get plain text?

How to hide columns in a bar chart with value = 0

How can I accomplish this using RadChart? With the Microsoft Chart control, you can set the minimum scale to 1 for the axis.
I've tried setting the YAxis minvalue, but this does not have the desired effect

<

YAxis MinValue="1">

Thanks for your help,
Dean
