Multiple ImageManager Dialogs w/custom ContentProviders

I have 2 image libraries that I would like to be able to insert images into the Editor from.

I have written 2 custom FileBrowserContentProviders.

I can get the existing ImageManager toolbar button to work with the custom ContentProviders.

I would like to add a 2nd toolbar button to access the other image library. I would like it to use the same FileBrowser dialog and return the same img information (alt text, longdesc, etc).

I have looked at the examples for adding custom dialogs, but would like to use the existing FileBrowser dialogs.

I have also looked at the RadDialogOpener, and was able to open the FileBrowser dialog from a button.

Any help is appreciated. Thanks.

Binding Custom Source to Grid

Hello All,

I want to bind the data dynamically to the RadGrid control [Columns would be known at the run time only] .

The Data Source for the RadGridView is a Generic List Collection of “OperatingCondition”.

public class OperatingCondition

{

public OperatingCondition(int stage)

{

this.Actual = new string[stage];

this.Theoritical = new string[stage];

}

public string OpCondtition { get; set;}

public string[] Actual { get ; set; }

public string[] Theoritical{ get; set;}

}

Actual and Theoritical coulmns has to created based on the number of stages. Eg: If the stage is 3, then grid should show the 3 Actual and Theoritical values as columns in the grid and each Actual and Theoritical column headers should be grouped to show the stage number.
Please suggest how to bind this datasource to the grid.

Pop Up editor Shows on enter press

I need a good workaround for an Issue I found with the radgrid.

When I press enter while focus is anywhere on my page (in another control or wherever) focus is automatically transferred to the insertCommand button in the grid header which causes the popup editor to show up.

Here is how I declare the grid in markup:

    
            <asp:UpdatePanel ID="upnlGrid4" runat="server" > 
        
                <ContentTemplate> 
        
                    <telerik:RadGrid ID="gvFirmInfo" runat="server" Width="550px"> 
        
                        <MasterTableView EditMode="PopUp" CommandItemDisplay="Top" CommandItemSettings-AddNewRecordText="Add Location"  
        
                                     ShowHeadersWhenNoRecords="true" ShowHeader="false"  
        
                                     NoMasterRecordsText="information is not available. <br/> Please click 'Add Location' to add the contact information for each location" 
        
                                     AlternatingItemStyle-BackColor="White" AlternatingItemStyle-BorderStyle="Solid"  
        
                                     AlternatingItemStyle-BorderWidth="1px" AlternatingItemStyle-BorderColor="#C9C4D1" 
        
                                     ItemStyle-BackColor="#E0E0E0" ItemStyle-BorderColor="#FFFFFF" ItemStyle-BorderStyle="Solid" 
        
                                     ItemStyle-BorderWidth="0px" BorderColor="#C9C4D1" BorderWidth="1px" BorderStyle="Solid" GridLines="None"> 
        
                            <EditFormSettings InsertCaption="Add Location" CaptionDataField="" PopUpSettings-Modal="true"/> 
        
                            <Columns> 
        
                                <telerik:GridBoundColumn DataField="rowId" HeaderText="Row ID" UniqueName="rowId" 
        
                                    Visible="False" EditFormColumnIndex="-1"> 
        
                                </telerik:GridBoundColumn> 
        
                                <telerik:GridTemplateColumn UniqueName="CheckBoxTemplateColumn"> 
        
                                    <ItemTemplate> 
        
                                        <asp:CheckBox id="ChkDelete" AutoPostBack="false" runat="server"></asp:CheckBox> 
        
                                        <asp:Label runat="server" Text="Delete Location"></asp:Label> 
        
                                    </ItemTemplate> 
        
                                </telerik:GridTemplateColumn> 
        
                                <telerik:GridButtonColumn CommandName="Edit" Text="Edit" UniqueName="columnEdit" ItemStyle-Width="35px"> 
        
                                </telerik:GridButtonColumn>                    
        
                            </Columns>                      
        
                        </MasterTableView> 
        
                    </telerik:RadGrid> 
        
                </ContentTemplate>  
        
            </asp:UpdatePanel>

My grids are dynamic and are built using advanced binding like so:

    
            Protected Sub gvFirmInfo_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles gvFirmInfo.NeedDataSource 
        
                    Dim sqlString As String = "" 
        
                    Dim sqlparam(2) As SqlParameter 
        
                    Dim ds As New DataSet 
        
                    Dim dr As SqlDataReader = Nothing 
        
                    Try 
        
                        Conn = New SqlConnection(ConfigurationManager.ConnectionStrings("****").ConnectionString) 
        
                        Conn.Open() 
        
                        SetParam(sqlparam(0), "@recId", Data.SqlDbType.Int, 4, m_rec_id) 
        
                        SetParam(sqlparam(1), "@recType", Data.SqlDbType.Char, 2, m_rec_type) 
        
                        sqlString = "select...***" 
        
                        ds = SqlHelper.ExecuteDataset(Conn, Data.CommandType.Text, sqlString, sqlparam) 
        
                        gvFirmInfo.DataSource = ds 
        
                    Catch ex As Exception 
        
                        '***** 
        
                    End Try

The problem occurs in IE 8 as well as Firefox 3.015

What do you all recommend for working around this issue?

Cheers!

Having multiple custom grid stylesheets causes styling conflicts with other controls

I use custom stylesheets for most of the Telerik AJAX controls I use in a Web application I'm working on for a client, including a stylesheet for the Telerik grid control. I recently decided I needed a second stylesheet with some changes to reduce padding in the grid and some border adjustments and I discovered that creating the second custom stylesheet actually changed the appearance of other unrelated Telerik controls - specifically, I noticed that on a different page that contains ListBox controls with transfer behavior, the ListBoxes lost their borders, transfer buttons, and drag-n-drop stylings. To prove that it was indeed the new stylesheet that was causing the issue, I simply deleted the style sheet and the ListBoxes rendered normally. I also tried putting the stylesheet back into my project but commenting out all of it's style definitions and it still seemed to cause a conflict with the ListBox styles.

Is this a known issue? Shouldn't I be able to have multiple stylesheets for individual Telerik controls?

firefox event model

I am maintaining inherited code on an existing web site. On the client side event of some controls, we have code like this:

    
            function CustComboBoxDropDownOpeningHandler(sender, args) 
        
            { 
        
                  .... [code]... 
        
                  if (event.type == "propertychange") 
        
                         args.set_cancel(true); 
        
                  ..... [code].... 
        
            }

Firefox does not give global access to the event object - it must be passed as a parameter. For this reason, Firefox will not work for these controls as it is implemented above. Is there a way to access the event object through the control? Or is there a different signature we can give to the method to allow access the event object? How can we know the type of event that caused this method to fire?

Thanks for your help!

menu does not highlight the selected item

q2 2009

VS 2008

Hiya,

I've got a menu that successfully displays the imageUrl

However, when I select a particular menuItem, I want the menu item to display a different image, to denote the fact that the menu has been selected...

    
            SelectedImageUrl="~/IMG/imgHome.gif"

I know for a fact that this image can be found for the menuItem, because, if I assign it to “imageUrl”, then it works.

Any ideas, I’d have thought that this would have been fairly simple.

Thanks,

yogi

If, in Opera, you create a new event on the Scheduler demo page and the invoke a calendar popup and click on the "title & navigation popup zone" the resulting window is hidden behind the calendar itself (see attached screen shot).
