I save multiple variations of images and then I am filtering the Image Manager filelist to only show 1 of each kind of them.
When I click "Image Editor" to load the ImageEditorDialog, is it possible to load a different file than the one selected from the list?

For example the list shows:
1_thumb.jpg
2_thumb.jpg
...

but when I select 1_thumb.jpg, and click "Image Editor" I want to load "1_source.jpg" for example (which exists but is not shown in the list).

Is there a function that I can override to do this?

RadGrid OnRowClick pass cell value to label without postback

I have a RadGrid being populated from a SQL stored proc and have set the OnRowClick event to properly show the value in an alert box...I need to know how to pass this value back to my vb.net code behind to show in a label or to use for a second query (such as customer details).

Again, I do not want a post back as I just want the label to reload or an Ajax panel.
Here is the code to handle the OnRowClick event:

    
            function custClicked(sender, args) { 
        
                var grid = sender; 
        
                var MasterTable = grid.get_masterTableView(); 
        
                var row = MasterTable.get_dataItems()[args.get_itemIndexHierarchical()]; 
        
                var cell = MasterTable.getCellByColumnUniqueName(row, "COMPANY"); 
        
                alert(cell.innerHTML); 
        
            }

Thanks in advance for your help!

Common Functionality For All My RadGrids

I want shared functionality for all RadGrids in my project, but I can't figure out how. I started with a WebUserControl (ascx) but learned it requires the same markup for all instances, which I can't as I need different columns in different pages, along with other property settings.

Is there a way to create a control that wraps/inherits a RadGrid that allows me to create shared methods, events, and properties, but have different markup on different pages? Or is that not possible and I need to copy-paste my server-side code to all instances and pages? Thanks.

TextChanged

When RadSpell makes changes to a textbox it does not cause the TextChanged event to fire. I tried calling a __doPostBack OnClientCheckFinished and it posts back but does not handle the TextChanged event on postback. Here's the code I am using at this point (I've tried without the __doPostBack call and with AutoPostback=True and it doesn't postback at all):

ASPX

                    <asp:TextBox runat="server" ID="ModuleTitleBox" Width="700" TextMode="MultiLine" Rows="1" AutoPostBack="true" />         
            <telerik:RadSpell ID="Radspell1" Runat="server" ControlToCheck="ModuleTitleBox" ButtonType="ImageButton" IsClientID="false" Skin="Black" OnClientCheckFinished="checkFinished"  />         
                     

JS

                    function checkFinished(sender, args) {         
                args.suppressCompleteMessage = true;         
                __doPostBack(sender.get_controlToCheck(), '');         
            }         
                     

VB

                    Protected Sub SaveTitleEdit(ByVal sender As Object, ByVal e As System.EventArgs) Handles ModuleTitleBox.TextChanged         
                'saves changes to database here         
            End Sub

Window Resize Lag (~.5 sec)

I'm using nested splitters (splitters occupy entire page) with almost nothing but text inside, and when the browser window is re-sized there is a noticeable lag for the panes to refit in the window. Use of "VisibleDuringInit" only works when the page is loaded.
This is not an issue with your examples, since the splitters don't get resized with the browser window.
I saw a post here from 2007 that recommended enclosing the Radpane contents in <div RadResizeStopLookup="true" RadShowStopLookup="true" >...</div> with some additional JavaScript.
(See http://www.telerik.com/community/forums/aspnet-ajax/splitter/slow-window-resize.aspx).
I attempted this, and there was no difference.
Is there any way to get rid of this lag or disguise it.
This doesn't happen when I use frames (which I would really prefer not using). It doesn't happen with Obout's splitters, but their support is not good, and I really like everything else about your products.
If I can't resolve this problem, I'll probably have to use your system with frames (if that doesn't create even more obstacles).

Best regards,
Mike

[Solved] Newbie - no Add New Record

Hi, it's my first go at Telerik controls. Can't seem to get the Add New Record to show anywhere. I'm working in Visual Studio 2010, .NET 4.0, Windows 7 and am using what is available for download as a trial.

snippets from my aspx file:

    <telerik:RadGrid ID="rgDealerMaintenance" AutoGenerateColumns="False"
        AllowAutomaticInserts="True" GridLines="None" ShowFooter="true" runat="server" >
    <MasterTableView EditMode="InPlace" DataKeyNames="RegistrationID" HeaderStyle-CssClass="body_text_black_BOLD">
    <CommandItemSettings AddNewRecordImageUrl="Images/AddRecord.gif" AddNewRecordText="Add New" />
    <Columns>
        <telerik:GridBoundColumn DataField="RegistrationID" Visible="false" />
        <telerik:GridBoundColumn UniqueName="txtFirstName" DataField="FirstName" HeaderText="First Name">
        </telerik:GridBoundColumn>
...
        <telerik:GridEditCommandColumn EditText="Edit" UniqueName="EditCommandColumn" UpdateText="Update" CancelText="Cancel" HeaderText="Edit">
        </telerik:GridEditCommandColumn>
        <telerik:GridButtonColumn CommandName="Delete" Text="Delete" HeaderText="Delete">
        </telerik:GridButtonColumn>
    </Columns>
    </MasterTableView>
    </telerik:RadGrid>
the ShowFooter shows the footer, but doesn't put anything in it
what am I missing?

I don't want to put the add into the edit button - I am working with an application which contains an already written program which keeps the add and update separate and want to be consistant

RadGrid lose Headers

Hi there.

This is my first trip with RadControls. I've created an usercontrol, which shows a Grid. My datasource is a DataTable, wich is populated on NeedDataSource event. I have to dynamically generate all columns of DataTable at runtime, so my ASCX file is pretty poor:

    
            <TELERIK:RADGRID ID="RadGrid1" RUNAT="server" ALLOWSORTING="true">  
        
            </TELERIK:RADGRID>

Also i need to group data. Therefore, i add columnbound on codebehind. Here is the important part of NeedDataSource

    
                        RadGrid1.DataSource = table;  
        
                        RadGrid1.GroupingEnabled = true;  
        
                        RadGrid1.AutoGenerateColumns = false;  
        
                        GridBoundColumn boundcolumn;  
        
                        foreach (DataColumn column in table.Columns)  
        
                        {  
        
                            if (column.ColumnName == "Name")  
        
                            {  
        
                                continue;  
        
                            }  
        
                            boundcolumn = new GridBoundColumn();  
        
                            boundcolumn.DataField = column.ColumnName;  
        
                            boundcolumn.HeaderText = column.ColumnName;  
        
                            RadGrid1.MasterTableView.Columns.Add(boundcolumn);  
        
                        }  
        
                        GridGroupByExpression expression = new GridGroupByExpression();  
        
                        GridGroupByField groupbyfield = new GridGroupByField();  
        
                        groupbyfield.FieldName = "Name";  
        
                        groupbyfield.HeaderText = " ";  
        
                        groupbyfield.HeaderValueSeparator = string.Empty;  
        
                        groupbyfield.FormatString = "{0}";  
        
                        expression.SelectFields.Add(groupbyfield);  
        
                        groupbyfield = new GridGroupByField();  
        
                        groupbyfield.FieldName = "Name";  
        
                        expression.GroupByFields.Add(groupbyfield);  
        
                        RadGrid1.MasterTableView.GroupByExpressions.Add(expression);  
        
                        RadGrid1.EnableViewState = true;

All works fine and the output is really pretty. But if i collapse one group, all column headers will be lost. I've also implemented export to Excel and PDF. It generates a file, but there are much more columns and some values are System.Data.DataRowView. Maybe it's the same reason?

Please advise me. Thanks
