Hello,

I have a master page that loads a RadTabStrip into it's ContentPlaceHolder.  When the user clicks on a tab a WebUserControl is dynamically loaded into the place holder.  Here's the code:

private void LoadMyUserControl(string controlName, Control parent)
{
    parent.Controls.Clear();
    UserControl ctrl = (UserControl)LoadControl(controlName);
    string userControlID = controlName.Split('.')[0];
    userControlID = userControlID.Replace("/", "").Replace("~", "");
    ctrl.ID = userControlID;
    parent.Controls.Add(ctrl);
}

One of the user controls contains a RadComboBox that's loaded with values.  When the user selects a value from this combo box I load a RadGrid into the user control based on the selected value from the combo box.  

The RadGrid contains one column and a NestedViewTemplate that contains a Nested RadGrid.  Within this nested grid I have some GridTemplateColumns that contain RadButtons within their ItemTemplates.  When the user clicks on one of these buttons I display a panel (make it visible/invisible) that contains another RadComboBox that gets its values based on which button was clicked and the value of the current cell.

The problem is that every time I click the button the entire page reloads (posts back), and if there are a lot of records in the nested grid it takes a long time for the panel to become visible.  I have ajaxified the main radgrid by using a RadAjaxManagerProxy within the user control.  I also tried ajaxifying the nested grid and the buttons within the ItemDataBound event of the nested grid.  

None of my efforts have paid off.  I'm not sure how to make it so that when I click the button only the RadComboBox within the panel gets updated and the whole user control page doesn't get posed back.  If I put "if (!IsPostBack)" on the page_load event of the user control then the radgrid won't get loaded.  

Can anyone help me figure out what to do with this?

I've got a RadGrid, and when double-clicking on a row, client-side javascript kicks in by openning up a pop-up Window:

 

 

function ShowEditForm2(id, rowIndex)

 

{

 

    ....
                var oWnd = window.radopen("AddConsultant2.aspx?consultantid=" + id, "EditDialog"); 
                oWnd.SetSize(650,400);
    ....
}

I can close this pop-up window, then go ahead and open it up again by double-clicking on another row back on the RadGrid.

This is all working fine, however I notice that the second time (and subsequent times after the second time) the pop-up window is openned, it will display the data from the previously openned instance (just for a second). Then immediately the correct data on the pop-up window gets rendered. This is somewhat annoying; is there a way to 'refresh' this? It seems to cache the display.

Hello,

How do you get appointment times in the current time zone?  I am exporting appointments using the RadScheduler.ExportToICalendar method.  But the times exported in the .ics file are in the wrong time zone.  Is that UTC?  I'm not displaying or converting to UTC times in the scheduler for my appointments.

 

Thanks.

Hello Telerik Support Team.

 I'm using dll 2014.1.403.40 version.

I would like to prevent pasting image into editor from web browser copy on context menu.

I had seen your editor demo here (http://demos.telerik.com/aspnet-ajax/editor/examples/cleaningwordformatting/defaultcs.aspx)

Demo is working good for blocking any pasting image by Control+V or paste on context menu.

I implemented sample project using your demo source unfortunately it does not work!!!!!!!!!!.

My test procedure is here.

1. Right click on the image in IE browser (That will shows browser context menu)

2. Click "Copy"

3. Pasting image into editor by pressing Control + V

4. Editor shows pasted image. (<--- Your demo is not shows image)

 What is the problem? I need to same feature like your demo.

 I'm attaching my sample project thank you.

Hello,

 

i have a project class with a list of employees assigned to each project

 

what i want to achieve here is that i want the stacked column chart to display names of projects on X axis for each series then add each resource of this project to the series as a series item with Y-Value of the total hours consumed by this employee on this project which is also a property coming from ProjectResource Class, i do it this way

 

Private Sub LoadAllProjects()

 dim Projects as new list(of Project)

 

Projects = GetAllProjects()

For Each nProject as Project in Projects

 Dim nSeries as new ColumnSeries

 Dim nAxisItem as new AxisItem

nAxisItem.labelstring = nProject.Name

nSeries.name = nProject.Name

For Each nEmp as Employee in Project.Resources

 dim nItem as new SeriesItem

nItem.Name = nEmp.Name

nitem.yvalue = nEmp.TotalUtilized

nSeries.Items.Add(nItem)

 

Next

RadHtmlChart1.PlotArea.Series.Add(nSeries)

Next

End Sub

 

Using this the either all items get loaded into first series or they duplicate in each series, i have tried everything possible and its not working

 also the legend is display the project.names thats because im assigning Series.Name to Project.Name and i have to remove it but i need the legend to display the names of employees in each project

 

Help is really appreciated, thanks

I noticed when I have an error, the ajax loading panel just goes away and doesn't show the error details on my label. 

On my content page I have a sub

Sub UpdateRecord(ByVal strRetry As String, ByVal strSender As String)
        Dim sb As New StringBuilder()
        Try
           
            
            Throw New Exception("Oh no! deadlock")
            
        Catch ex As Exception
            'Handle true exceptions here
            litError.Text = sb.ToString()
            If litError.Text > "" Then
                pnlError.Visible = True
                RadAjaxManager.GetCurrent(Page).ResponseScripts.Add("window.scrollTo(0,0);")
            End If
        End Try
    End Sub

 

Master page

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

 

 

CustomErrors is off

 

How do I get this to show the error info on the screen. This worked fine in 1.1 and 2.0 apps.

I dynamically created raddocks on the server side.

dock.DockPositionChanged += new DockPositionChangedEventHandler(dock_DockPositionChanged);

So I used this line of code to add event handler, however it only gets fired when the control is dropped to another position. It doesn't get fired if I dropped it to the same position.

How do I make it gets fired even if I drop it to the same position. Thanks.

how could I program that the draghandle in a horizontal slider can only be moved one tick to the right?

 

So the moves to the left and multiple ticks to the right are blocked client side?
