Button inside tooltip not fireing postback

Hello,
I have tooltipified a column in a infragistics UltraWebGrid using the tooltipmanager. When the user hoovers a small icon a tooltip shows up with the following content:

    
            <table cellspacing="0" cellpadding="0" width="370px">  
        
                <tr> 
        
                    <td>&nbsp;<asp:Image id="Image3" runat="server" ImageUrl="~/images/no_pic.jpg"></asp:Image></td>  
        
                </tr> 
        
                <tr> 
        
                    <td colspan="2"><asp:FileUpload id="FileUpload1" Width="370px" runat="server"></asp:FileUpload></td>  
        
                </tr> 
        
                <tr> 
        
                    <td colspan="2"><asp:linkbutton id="cmdUploadImage" runat="server" Visible="true" resourcekey="cmdUploadImage" text="Upload" borderstyle="none" cssclass="CommandButton" OnClick="cmdUploadImage_Click"></asp:linkbutton>&nbsp;   
        
                        <asp:LinkButton id="btn_deleteImage" runat="server" CssClass="CommandButton" Visible="true" resourcekey="deleteImage" Text="Delete" BorderStyle="none"></asp:LinkButton>&nbsp;   
        
                    </td> 
        
                </tr> 
        
            </table>

This is a custom webusercontrol that I have created and the RadToolTipManager loads it the following way:

    
            protected void uwg_rackTypeGrid_InitializeRow(object sender, Infragistics.WebUI.UltraWebGrid.RowEventArgs e)  
        
                    {  
        
                        Infragistics.WebUI.UltraWebGrid.TemplatedColumn imageColumn =  
        
                            (Infragistics.WebUI.UltraWebGrid.TemplatedColumn)uwg_rackTypeGrid.Columns.FromKey("imageColumn");  
        
                        Control target = ((Infragistics.WebUI.UltraWebGrid.CellItem)  
        
                                imageColumn.CellItems[e.Row.Index]).FindControl("img_rackImage");  
        
                        if (!Object.Equals(target, null))  
        
                        {  
        
                            if (!Object.Equals(this.RadToolTipManager1, null))  
        
                            {  
        
                                Infragistics.WebUI.UltraWebGrid.UltraGridRow myRow = (Infragistics.WebUI.UltraWebGrid.UltraGridRow)e.Row;  
        
                                //Add the button (target) id to the tooltip manager  
        
                                this.RadToolTipManager1.TargetControls.Add(target.ClientID, myRow.Cells.FromKey("RackType_ID").ToString(), true);  
        
                            }  
        
                        }  
        
                    }

and here is my AjaxUpdate even that fires when the user hoovers the small icon:

    
            protected void RadToolTipManager1_AjaxUpdate(object sender, Telerik.Web.UI.ToolTipUpdateEventArgs e)  
        
                    {  
        
                        this.UpdateToolTip(e.Value, e.UpdatePanel);  
        
                    }  
        
                    private void UpdateToolTip(string rowID, UpdatePanel panel)  
        
                    {  
        
                        Control ctrl = Page.LoadControl("~/DesktopModules/STS.POP.WebControls/TT_ImageRackType.ascx");  
        
                        panel.ContentTemplateContainer.Controls.Add(ctrl);  
        
                        STS.POP.WebControls.TT_ImageRackType ttImageRackType = (STS.POP.WebControls.TT_ImageRackType)ctrl;  
        
                        ttImageRackType.RackType_ID = rowID;  
        
                    }

So far everything works fine, the tooltip is loaded with my custom webusercontrol inside.

The user can then select an image using the standard fileUpload control and then click the cmdUploadImage linkbutton. The problem is that the click is not firing any postback and because of that I can not read any filename from the fileUpload control.

The UltraWebGrid is set to AJAX=false and is firing postbacks when used. So its not the grid. I am not using any ajaxpanel of some sort. So why am I not getting a postback when clicking on the cmdUploadImage button that is inside the toolTip?

Any help would be GREATLY appreciated!

Thank you,
Amer

Disappearing context menu after downloading a file in radgrid

We have a problem witch context menu in RadGrid. After downloading a file context menu is disappearing. Only refreshing the page can fix the menu.

Code example:

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="RadGridMenu._Default" %>

SubItems Not Showing Up...

I am using the RadMenu Prometheus control and the child items for the radmenu are not showing up.

I used the "Build RadMenu" on the Smart Tag in design view, removed it from my master page into it's own page, am using the RadScriptManager, and have everything as it should be.

EDIT: Firebug is showing 3 errors...
Sys is not defined
Sys is not defined
Type is not defined

But yet, the child items still do not show on mouseover. Code below:

    
            <telerik:RadScriptManager ID="RadScriptManager1" runat="server">

Back button problems with listbox driving grid rebind

Hello, I have a page with a listbox showing some time selections ('This Month', 'This Year', etc.) and a grid showing the appropriate events. By default, the page shows this month's events.

The listbox drives the grid on postback. Let's say I click 'This Year'. The grid rebinds to show all events for this year. But when I click the back button, the grid goes back to show 'This month' but the listbox doesn't - it still shows 'This Year'.

The grid is using AJAX, the listbox isn't.

How can this be fixed? Thanks.

RadioButton with TextAlign "Left" wraps

When a radio button styled with RadFormDecorator has the TextAlign property set to "Left", the button portion of the control wraps to the next line. The expected behavior was that the button and label portion of the RadioButton would be on the same line.

    
            <body> 
        
                <form id="form1" runat="server">  
        
                    <asp:ScriptManager ID="ScriptManager1" runat="server" /> 
        
                <div> 
        
                  <telerik:RadFormDecorator ID="RadFormDecorator1" runat="server" Skin="Telerik" /> 
        
                  <asp:RadioButton ID="RadioButton1" runat="server" Text="Test" TextAlign="Left" />      
        
                </div> 
        
                </form> 
        
            </body>

RadCombobox passing data to RadGrid

I have a RadComboBox with 2 columns in the EditItemTemplate of a RadGrid's TemplateColumn. It uses streaming through ExternalCallBackPage to get its list data.

1.How do I implement a javascript on client side which updates a seperate column of RadGrid with the entry the user has selected.

2. The streaming tends to take time to load the data over. Is there any way to ensure that the data passing to this seperate column could be done once the loading is complete even after the user has left the control?

3. Right now the ExternalCallBackPage I'm using is having 5 different RadComboBoxes for streaming to the appropriate screens. Is this safe? Will there be any performance improvment if I shift each of the controls to its own individual page?

Thank you.
