Header text is not displaying correctly

We have a column in a Grid whose text is 'a&b' at html but on browser it is displaying as 'a'. When I edit that text to 'a & b' with single space before and after & then it is displaying correctly i.e 'a & b'. This is our client requirement to display the text on header as 'a&b'. Is there any possibility to allow that text to display in a grid header?

Very slow response when transferring items

We are having a hard time figuring out a solution to a long running issue. We are using a RadListBox to display a list of items such as names on a page. There are 2 lists where 1 is the selector list and the second is the "selected" list. When the selector list gets to contain somewhere in the range of 2,500+ names, the transfer runs unacceptably slow. We've tried to disable viewstate, but that breaks our code since we need to handle the transfer on the server side via an AJAX call. When we debug the code, it takes almost 25 seconds for the server-side CodeBehind method to execute.

Please advise on what can be done to improve performance for a RadListBox with transfer enabled that contains large lists of data.

Thank you,

Ed Sudit

Finding a control in the RadGridView.EditFormSettings.FormTemplate

I have a page with a RadGrid on it. In that RadGrid I'm using <EditFormSettings EditFormType="Template"> to handle the editing of the data. In that FormTemplate I have a FileUpload control where I'm allowing users to upload a file. I planned on handling the file upload in a seperate function. Problem is trying to get to the FileUpload control. Can someone help me? Code sample below:

<telerik:RadGrid

ID="rgvwUserList"

runat="server"

AllowAutomaticDeletes="True"

AllowAutomaticInserts="True"

AllowAutomaticUpdates="True"

AllowFilteringByColumn="True"

AllowPaging="True"

AllowSorting="True"

AutoGenerateColumns="False"

CellSpacing="0"

DataSourceID="sdsUserList"

EnableLinqExpressions="False"

GridLines="None"

PageSize="20"

ShowGroupPanel="True"

Width="900px">

<ClientSettings AllowDragToGroup="True"/>

<MasterTableView

AutoGenerateColumns="False"

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridBoundColumn DataField="DisplayName" FilterControlAltText="Filter DisplayName column" HeaderText="DisplayName" ItemStyle-Width="20%" ReadOnly="True" SortExpression="LastName" UniqueName="DisplayName"/>

</Columns>

RadTreeView node text highlight/selection

I'm trying to figure out how to get the treeview to allow clean text selection of the text in the nodes and items inside node templates (labels etc). I have searched all over for a solution to this and it seems to be that different versions of RadTreeView allow this while others do not.

For example here, you can highlight the text of the nodes and smaller parts of the text fine:
http://mono.telerik.com/TreeView/Examples/Functionality/SingleExpandPath/DefaultCS.aspx

Yet in this newer example, you can't:
http://demos.telerik.com/aspnet-ajax/treeview/examples/functionality/expandanimation/defaultcs.aspx

You can sometimes select the text if you start clicking far outside the node and drag, but there is no way to select sub parts of the node text.

If anyone has any idea how to get text selection to work properly with TreeView please help!

findItemByValue not working using concatenated string as parameter

Hi,

I'm sure this is something silly on my part, but I can't spot it.

The following code works:

var x = 'text';

var y = 'Red';

var selectedColorButtonValue = String(x + y);

var selectedColorButton = toolBar.findItemByValue(selectedColorButtonValue);

Now, since the actual value of y is dynamic and only known at run time, I have this code:

var selectedColorButtonValue = getColorButtonValue(fontColor); // Returns 'Red' for this demo

selectedColorButtonValue = String('text' + selectedColorButtonValue);

var selectedColorButton = toolBar.findItemByValue(selectedColorButtonValue);

The above does NOT work. The toolbarbutton that I'm trying to find is not found!

The toolbarbutton in question is one of several items in a RadToolBarSplitButton.

I have written to the console, and the value of selectedColorButtonValue appears fine.

Can anyone spot what I'm doing wrong.

Thanks

Jim

pass parameters to user control used for edit mode

Hello

I'm having problem passing parameters to user control used in edit mode of radgrid

I Have a RadGrid with some users data. I use a custom user control for FormTemplate.

The user control has it's own logic implemented to edit user data and takes one parameter "id_user". (It has public String id_user with get and set method defined in codebehind)

I tried to pass this parameter to UserControl as seen in code below, but it doesnt work. when i pass this parameter to label it shows. User control also works fine if I pass static parameter (example: id_user="2" ).

What is the right way to pass parameters to UC?

    
            <EditFormSettings EditFormType="Template"> 
        
               <FormTemplate> 
        
                   <asp:Label ID="Label4" runat="server" Text='<%# Bind("id") %>'></asp:Label> 
        
                   <uc1:edit_user ID="edit_user1" runat="server" id_user='<%# Bind("id") %>' />    
        
               </FormTemplate> 
        
               <EditColumn CurrentFilterFunction="NoFilter" FilterListOptions="VaryByDataType" 
        
                           uniquename="EditCommandColumn"> 
        
                </EditColumn> 
        
            </EditFormSettings>

I'm would also like to know how to pass parameters when attachig UserControls like this:

    
             <EditFormSettings EditFormType="WebUserControl" UserControlName="edit_user.ascx">

Thank you
