[Solved] help with showing and hiding grid

Hey all.
As you may have inferred from the title, I'm having some problems showing and hiding the grid.

I have three grids each tied to its own tab page. They are not contained in any tab page but are visible based on which tab is active.

The tabs are at the top of the page.
Below the tab control I have a table. The table has three rows; two have a grid and the third row has some other UI controls.

When my page loads, tab 1 is active and so I hide table rows 2 and 3 (to avoid some UI quirks in the markup I set the display style of rows 2 and 3 to none).

As I tab through, I show and hide these table rows accordingly.
So after the page loads, I tab to the second tab, I hide rows 1 and 3 and toggle the visibility on row 2 at which point grid 2 is visible but the sizing is all messed up. Everything is squished up at the top of the grid div; the size of the master table view is very small. If I tab to another tab and tab back it corrects itself in IE but not Firefox.
If I open the dev toolbar in IE or Firebug in FF, it corrects itself.

I'm wondering if I can force it to correct itself.

Is there anything I can do?

Block Slider Auto Postback

I have slider with AutoPostBack property set to "true". How can I block auto postback when changing value of a slider with the client side API? E. g. I don't need postback to fire when running this code:
$find('slider_name').set_value(0);
At the same time I need postback to fire when I change value of a slider by Drag Handle.

GridButtonColumn Not Shown After Client-Side Binding

I'm using AJAX call to dynamically add rows to my RadGrid on the Client-Side. The data is initially loaded on the Server Side.

If there were X rows when the grid was initialized, adding the (X+1)th row, the GridButtonColumns are not rendered.

What the grid looks like before the Add

What the grid looks like Afterward

After the AJAX call adds the record to the appropriate SQL Table, I use a WebMethod in the page's Code Behind to retrieve all the data that should be in the grid.

I then bind that result to the grid (AGPermissions is the ID of the RadGrid):

    
                    function updateGrid(result) 
        
                    { 
        
                        var masterTableView = GetMasterTableView("<%=AGPermissions.ClientID %>"); 
        
                        if (result) 
        
                        { 
        
                            masterTableView.set_dataSource(result); 
        
                            masterTableView.dataBind();   
        
                            ToggleDivVisibility('ShowGridClient',true); 
        
                           var grid = $find("<%= AGPermissions.ClientID %>"); 
        
                           grid.repaint();

While tracing through the code, the correct data is stored within "result".

Here's the RadGrid definition:

    
                <telerik:RadGrid ID="AGPermissions" EnableViewState="false" runat="server" 
        
                    AllowPaging="false" AllowSorting="false" AllowFilteringByColumn="false" GridLines="None" 
        
                    EnableEmbeddedSkins="false" Skin="IMCGridStyle" ImagesPath="Grid"  
        
                    OnNeedDataSource="AGPermissions_NeedDataSource"> 
        
                    <ItemStyle Wrap="false" /> 
        
                    <MasterTableView  
        
                        AllowMultiColumnSorting="true"  
        
                        TableLayout="Auto"  
        
                        EnableNoRecordsTemplate="false"  
        
                        ClientDataKeyNames="AssetGroupID,AssetGroupPermissionType" 
        
                        AutoGenerateColumns="false" 
        
                        ShowHeadersWhenNoRecords="false"> 
        
                        <Columns> 
        
                                <telerik:GridBoundColumn DataField="AssetGroupID" Display="false" HeaderText="Asset Group ID" /> 
        
                                <telerik:GridBoundColumn DataField="AssetGroupName" HeaderText="Asset Group" /> 
        
                                <telerik:GridBoundColumn DataField="AssetGroupPermissionType" Display="false" HeaderText="Asset Group Permission Type" /> 
        
                                <telerik:GridBoundColumn DataField="AssetGroupPermissionTypeText" HeaderText="Permission Type" /> 
        
                                <telerik:GridButtonColumn  UniqueName="1MakeGroupMaster"  Visible="true" ButtonType="ImageButton" ImageUrl="Grid/btnMakeGM.jpg" CommandName="1MakeGroupMaster" Text="Make Group Master"></telerik:GridButtonColumn>   
        
                                <telerik:GridButtonColumn  UniqueName="2MakeGroupReader" ButtonType="ImageButton" ImageUrl="Grid/btnMakeGR.jpg" CommandName="2MakeGroupReader" Text="Make Group Reader"></telerik:GridButtonColumn>   
        
                                <telerik:GridButtonColumn  ConfirmText="Remove access to this Asset Group?" ButtonType="ImageButton" ImageUrl="Grid/btnRemove.jpg" CommandName="RemoveAccess" Text="Remove Access"></telerik:GridButtonColumn>   
        
                        </Columns> 
        
                        <NoRecordsTemplate> 
        
                            <div>There are no records to display.</div> 
        
                        </NoRecordsTemplate> 
        
                    </MasterTableView> 
        
                    <ClientSettings> 
        
                        <ClientEvents  
        
                            OnCommand="RadGridCommand"  
        
                            OnDataBound="TestThis"/> 
        
                    </ClientSettings>         
        
                    <PagerStyle AlwaysVisible="true" /> 
        
                </telerik:RadGrid>

If I do a refresh of the page, the Server Side methods load and display the grid properly. Any help on why this is happening would be appreciated.

I'm using the Q3 2008 version.

Thanks.

How to set up any control property by parameters stored in xml

Hello.

We are developing business rule engine. Users can create database structure, objects, web forms and so on. Now, we would like to provide the users with the ability to set up Telerik ASP.NET Ajax controls using xml set up files.

These files have the same structure like html code snippets used in VS.NET Designer for every type of your control.

The main reasons for that is:

1) we can easily create xml schema for "supported subset of features"
2) there are too many features to create special form for every property of the control
...

The question is How to interpret there xml files to set up controls.

1) With help of reflection. => We need to cast strings in xml attributes to proper types.
2) Use already existing functionality in VS.NET designer to read aspx files and set up controls on the fly.

What do you think about that? I know nothing about the second option. Can you help me, please?

Thank you very much.

Tom

AdvancedEditForm question

Hi,

I have a simple question. If I add a child element <AdvancedEditTemplate> to my radScheduler I have to specify all of the components; I can't just add one asp:label for example. All the other elements vanish.

I need just to validate the advanced edit form, by the way, is there any other method to do this? MsgBox which is called inside the RadScheduler1_AppointmentUpdate event also doesn't work.

Maybe I overlooked the solution on other threads, because it seems a very common problem.

Anyway,
thanks in advance for your reply.

LP, Luka

Load HTMLEditor.js conditionally

In order to optimize sharepoint public facing web sites, could htmleditor.js be loaded conditionally? It was noticed the file size of HtmlEditor.js is about 283 KB which seems like a lot to load especially those with slower connections. Would loading this conditionally be possible? If so, how do we know about setting this up?

Thanks,
Chris
