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()); }
}

Embedding a user control incorporating a RadGrid inside a RadCombo, which is in turn embedded in a RadGrid GridTemplateColumn

Hello. I would like to embed a user control that uses a RadGrid control inside a RadComboBox so that the control displays when the user clicks the dropdown. I would then like to use this RadComboBox in a GridTemplateColumn inside another RadGrid. I'll include the markup below.

<tel:GridTemplateColumn HeaderText="Assign To" UniqueName="AssignTo" AllowFiltering="false">

<ItemTemplate>

<tel:RadComboBox id="rcAssignTo" runat="server">

<ItemTemplate>

<uc:CaseworkerList ID="ucCaseworkerList" runat="server" DisplayMode="CaseTransferAssign"

OnAssignToCaseworker="ucCaseworkerList_AssignToCaseworker" />

</ItemTemplate>

</tel:RadComboBox>

</ItemTemplate>

</tel:GridTemplateColumn>

ucCaseworkerList has a public load method, which I call in the grid's ItemDataBound event handler as follows.

/// <summary>Handles rgActiveCases' ItemDataBound event by getting the CaseProgramUser

/// and AgencyProgram keys, finding the CaseworkerList control embedded in

/// the GridTemplateColumn's combobox, and calling its load method.</summary>

///

/// <param name="sender">Source of the event.</param>

/// <param name="e"> Grid item event information.</param>

protected virtual void rgActiveCases_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item.ItemType == GridItemType.Item || e.Item.ItemType == GridItemType.AlternatingItem)

{

var item = e.Item as GridDataItem;

var cpuKey = (int)item.GetDataKeyValue(Constants.EntityKeys.CASE_PROGRAM_USER_KEY);

var apKey = (int)item.GetDataKeyValue(Constants.EntityKeys.AGENCY_PROGRAM_KEY);

var dropDown = item.FindControl("rcAssignTo") as RadComboBox;

if (dropDown != null)

{

var nestedView = dropDown.FindControl("ucCaseworkerList") as CaseworkerList;

if (nestedView != null)

{

nestedView.LoadCaseworkerList(apKey, cpuKey);

}

The problem with the above code is that nestedView always turns out to be null. In addition, I'm concerned that this code may prove to be too slow, and thus cause server timeouts. I'd appreciate any advice you can offer.
