<telerik:RibbonBarButton ID="rbbHelp" Size="Large" Text="Help" ImageUrlLarge="Ikcsy/Png/Help.png" />

then in code file a have a fuction

protected void RadRibbonBar1_ButtonClick(object sender, RibbonBarButtonClickEventArgs e)

{

switch

(e.Button.Text.ToString())

{

case "Help":
try
{

Response.Clear();

Response.ContentType =

"text/pdf";

Response.AppendHeader("Content-Disposition", "attachment; filename=" + "HelpFile" + ".pdf" );

string file_path ="\\Help\\HelpFile.pdf";

Response.TransmitFile(file_path);
Response.End();

}

catch(Exception ex)

{

}

break;

}
}
after I clicked the button i get an error after Response.End :
ex = {Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack.} and after this I get on page jscript error Sys.WebForms.PageRequestManagerParserErrorException. What can I do to download/transmit the file correctly ?

RadGrid Change row background color

Hi,
In each row of my RadGrid I have a CheckBox as shown below.

<telerik:GridTemplateColumn HeaderText="Is Critical?" HeaderButtonType="TextButton" UniqueName="critical">

<ItemTemplate

<asp:CheckBox ID="chkCritical" runat="server" />

</ItemTemplate>

</telerik:GridTemplateColumn>

When the user checks the CheckBox system makes an ajax call from clientside and updates the database. This part is working fine.
I want change the row background color on check/uncheck of the CheckBox on clientside. Could not find a method to set background color on DataItem. Please help.

Standalone imageManager globalization

Hi,

I have a standalone ImageManger on the page which is not taking the correct globalization settings from the thread.

I have

Thread.CurrentThread.CurrentUICulture = new CultureInfo("de-DE")
Thread.CurrentThread.CurrentCulture = new CultureInfo("de-DE")

In Code behind but it is falling back to the default culture from web.config.

How can I set the dialog language correctly?

Tooltipify Image in Template Column

Hi, I have a RadGrid that gets bound with template columns that contain a single image (it's an indicator light). Here's the code for the template column:

                    Public Class GridImageItemColumn         
               Inherits GridTemplateColumn         
                     
               Public Class GridImageItemTemplate         
                  Implements ITemplate         
                           
                  Public column As GridImageItemColumn = Nothing         
                      
                  Public Sub InstantiateIn(ByVal container As Control) Implements ITemplate.InstantiateIn         
                     Dim image as New Image()         
                     image.ID = Me.column.UniqueName         
                     container.Controls.Add(image)         
                     AddHandler image.DataBinding, AdressOf image_DataBinding         
                  End Sub         
                     
                  Private Sub image_DataBinding(ByVal sender As Object, ByVal e As EventArgs)         
                     Dim dataItem As GridDataItem = CType(CType(sender, Control).NamingContainer, GridDataItem)         
                     If dataItem IsNot Nothing Then         
                     Dim image As Image = CType(sender, Image)         
                     image.CssClass = "t_img"         
                     Dim value As String = DataBinder.Eval(dataItem.DataItem, Me.column.DataField).ToString()         
                     If Not String.IsNullOrEmpty(value) Then         
                        image.ImageUrl = "~/images/" & value & ".png"         
                     End If         
                  End Sub         
               End Class         
                     
               Public Sub New()         
                  Dim template As New GridImageItemTemplate()         
                  template.column = Me         
                  Me.ItemTemplate = template         
               End Sub         

What I'm wondering is, how can I dynamically tooltipify these indicator lights? I've tried to do it via how the example states:

                    Me.RadToolTipManager1.TargetControls.Add(target.ClientID, (TryCast(e.Item, GridDataItem)).GetDataKeyValue("ID").ToString(), True)         

but .. that doesn't work since I have no way to find the target Image control, since the name isn't static (it isn't static, because there are n number of these columns).

Any clues?

Open master page RadWindow from content page

Hello,

I have a window (used to display error messages) which resides on the master page. This window is then called by a publically accessable function on the master code behind which can be accessed by the child pages. Now, if I attempt to use the RadGrid RowDrop function and an error occurs, the master window does not display. The window does appear if I force an error (give an invalid stored procedure name) on the population method, but in this situation a full page laod accurs.

I would greatly appreciate your assistance.

See sample code example below:

Master Page
--------------------
public void Show_Error_Msg(String strLocation, String strError)
{
            RadWindow objWindow = RadWindowManager1.Windows[0];
            (objWindow.ContentContainer.FindControl("lbl_error_local") as Label).Text = strLocation;
            (objWindow.ContentContainer.FindControl("lbl_error_msg") as Label).Text = strError;
            objWindow.VisibleOnPageLoad = true;
}

Content Page
---------------------

protected void RadGrid1_RowDrop(object sender, GridDragDropEventArgs e)
{
      try{
            throw new Exception("This is the error from the RowDrop function");
      }
      catch(exception err){ Master.Show_Error_Msg("Row Drop", err.Message.ToString()); }
}
