Hello

I have a textbox with an event handler for TextBox_OnTextChanged. I also have a RadComboBox.

When a value in TextBox changes, it does fire the TextBox_OnTextChanged event. In this handler the RadComboBox.SelectedValue is set to either '0' or a non-zero value - which looks to be correct under the debugger. I have ajaxified it. However, the RadComboBox selected value does not seem to be changing. How do I get the RadComboBox to reflect the changed value?

Thanks, Raka.

        protected void txtName_TextChanged(object sender, EventArgs e)
        {
            if (string.IsNullOrEmpty(txtName.Text))
            {
                rcbProgram.Enabled = true;
                rcbProgram.SelectedValue = "0";
            }
            else
            {
                rcbProgram.SelectedValue = subProgram == null ? "0" : subProgram.ProgramId.ToString();
                rcbProgram.Enabled = false;
            }
        }

One RadWindow blanks out when another is being resized or moved

I have two RadWindows side-by-side within a RadWindowManager. Both windows can be resized and moved, and are populated (say with some static html page). When I resize or move one of the windows by dragging the borders or titlebar, the other window that doesn't have focus blanks out for the duration of the drag. The contents reappear only when the resize/move operation is completed on the first window.

Can this behavior be modified, so that contents of the second window are visible even while the first window is being resized/moved?

I'm using version 2010.1.309.20, and my IDE is VS 2008, with .NET 3.5 SP1. The browser being used is IE 6.0.

Here is the body of my page:

    
            <body> 
        
                <form id="form1" runat="server">

                    </asp:ScriptManager> 
        
                <telerik:RadWindowManager ID="DBRadWindowManager" runat="server">  
        
                    <Windows> 
        
                        <telerik:RadWindow ID="CustomerWindow" runat="server" VisibleOnPageLoad="true" TabIndex="1" ReloadOnShow="true" 
        
                            BorderStyle="None" Behavior="Default" Height="250px" InitialBehavior="None" Left="5px"   
        
                            Skin="Telerik" Title="CUSTOMER" Top="20px" Width="300px" NavigateUrl="Source1.htm"

                </div>

Radgrid with nested view from generic class

I am using rad grid to load the data in a nested view and save it into the database using a generic class (get/set the data's based on the controls in the form).
After saving the data I need to reload the data back into the radgrid in the nested view (using OnDetailTableDataBind with HierarchyLoadMode=ServerBind).

I have all the required data in the form of an xml

<Rows>

<Row> Parent View

<SubRow>

Child View

</SubRow>

</Row>

</Rows>

Can any one please help how to set OnDetailTableDataBind event from a generic class?

Spell check integarion with CCD, Unable to pick suggested options from second time the popup loaded.

We are trying to integration spell check tool with MS CRM 2011 in Email activity. This is working fine with Web Client. But when we test the same in CCD, we are unable to select the suggested options from list of given options. But if suggested options framed have scroll bar, then we are able to pick a value. And this issue appears from second time when we load spell check for a control. Appreciate any suggestions.

Thanks,

Gantt export to PDF - Only export the viewable area or subset of columns

Some of our projects are very long, and our users would like to export just what is viewable on page web page to PDF. So, it would essentially be a narrow sliver of the entire Gantt chart, but every task (row) would be show. For example, show only a Gantt chart for the next 2 months of tasks, instead of the entire project. We thought about just pulling in a subset of tasks, but then we need to handle things like tasks that included in the next 2 months, then changing their start and end dates accordingly. However, we were hoping there was an easier way to set the start and end date of the entire Gantt chart so we can export just the time frame we are focusing on.
