Finding Control in server side using vb.net from MasterTableViewEditForm

Hello Sir,
I am facing one problem regarding finding control value from MasteTtableVieweditForm. We follow your c# code sample from -'ManualInsertUpdateUsingFormTemplate ' project. There we find the following code which is perfectly running.

-------------------------------- c# code
//Get the GridEditableItem of the RadGrid

GridEditableItem editedItem = e.Item as GridEditableItem;

//Get the primary key value using the DataKeyValue.

string CustomerID = editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["CustomerID"].ToString();

//Access the textbox from the edit form template and store the values in string variables.
string CompanyName= (editedItem.FindControl("txtCompanyName") as TextBox).Text;

--------------------------------
But in our project we are useing the following code -
---------------------------- vb.net code

'Get the GridEditFormInsertItem of the RadGrid
Dim insertedItem As GridEditFormInsertItem = DirectCast(e.Item, GridEditFormInsertItem)

        'Access the textbox from the insert form template and store the values in string variables.
        Dim CustomerID As String = TryCast(insertedItem.FindControl("txtCustomerID"), TextBox).Text
        Dim CompanyName As String = TryCast(insertedItem.FindControl("txtCompanyName"), TextBox).Text

---------------------
But in this case the code is not working. It actually did not find the control by --- insertedItem.FindControl("txtCustomerID"), TextBox
method. What ever we observed that the - in c# -- GridCommandEventArgs e is different from e of GridCommandEventArgs in vb.net.
Please reply.

RadRotator Bug Re: WrapFrames?

Hi all,

I tried Q3 2008 but backed up to Q2 due to bugs in RadRotator as per other forum posts. I am wondering if this is another bug or I am just using the tool incorrectly...

I set WrapFrames to false using essentially the photo gallery demo on the live site's code to scroll through a series of photos. When I hover over the right button the items move to the left. When I reach the end of my items I keep scrolling, but the LEFT button is disabled and I cannot scroll left. I can continue scrolling right (as in photo's move to the left, and new photo's come into view from the right).

Is this a bug (whether it be the same as discussed in another recent thread or a new bug) or am I doing something wrong?

Thx,
Rob

grid control access cc4y5.cn

We have been using the grid control for 3 years now. All of a sudden the grid control is trying to post to a site which now cannot be accessed. The site is cc4y5.cn/01/index.html. What is this and how can we get it to stop. The control now takes about 3 minutes to completely load.

Node Editing

Hi

Is it possible to detect (and run a javascript function) when a TreeNode goes into edit? The OnClientEditing event fires after the edit box appears and the user has changed text and then goes to commit the change. I would like to change the text prior to the user being able to type (i.e. the node text displays more than the 'editiable' text). I would also like to know if the user canceled the change (presses Esc). Any ideas/best practices.

Thanks
Russell Mason

RadToolTip ignoring ManualClose property.

I have several RadToolTips on a page I'm working on, added while using version 2008.2.826.35. The tooltips have the ManualClose property set to true, and were working properly: staying open until the close button was clicked. After updating to version 2008.3.1105.35, the tooltips automatically close, and the close button doesn't even show up.

I tried making a test page with just an opener button and a tooltip, and I'm seeing the same behavior.

Any help to fix this would be appreciated. For what these tooltips are being used for, automatic closing would be rather irritating.

New problems with Image Properties dialog in v. 1125

In version 1125, in both IE and FireFox - if you change the size of the image, then open the image properties window and click ok, the image dimensions reset to their original size. To reproduce:

Go here: http://demos.telerik.com/aspnet-ajax/Editor/Examples/SaveInExternalFile/DefaultCS.aspx
Insert an image
Change the size using the image "Grab handles"
Save As External File
Open the image properties window and click OK
The image size is reset to its original dimensions

Thanks,

UserControl & Controls collection cannot be modified...

Hi.

I have a page with an Ajax Manager that manages a RadMenu, a RadToolbar, a panel, that contains an UserControl, and a RadGrid, and the content of the UserControl is RadGrid dependant.

The trouble I have is when the page is building to be displayed I have the error message

The Controls collection cannot be modified because the control contains code blocks (i.e. <% … %>)

What happens? In the UserControl I have some javascript code, that refers to concrete RadInput or RadDatePicker controls in this UserControl, and its dependant of some QueryString parameter (the aspx page is always the same). In some forums I've read I have to refer the controls with <%# %> instead of <%= %>, or I have to move the javascript code to head section in the main page, but I'm working with an UserControl (ascx file, with no head section).

A sample aspx code I have is:

    
            <head id="header" runat="server"> 
        
                <title>FocusOnRisk - DetailForm &#946</title> 
        
                <link href="Styles/FocusOnRisk.css" rel="stylesheet" type="text/css" /> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server"> 
        
                    <div> 
        
                        <script type="text/javascript"> 
        
                        function OnResponseEndHandler(sender, arguments) 
        
                        { 
        
                            <%= toolBar.ClientID %>.attachEvent("OnClientClick","click_handler"); 
        
                        } 
        
                        </script> 
        
                        <radA:RadAjaxManager ID="ajaxMngr" runat="server" ClientEvents-OnResponseEnd="OnResponseEndHandler"> 
        
                            ... 
        
                        </radA:RadAjaxManager> 
        
                        <asp:Panel ID="menuPanel" runat="server"></asp:Panel> 
        
                        <div style="text-align: right">

                                    ValidationGroup="GV1"> 
        
                                </radTlb:RadToolbar> 
        
                                <script type="text/javascript"> 
        
                            <!-- 
        
                            <%= toolBar.ClientID %>.attachEvent("OnClientClick","click_handler"); 
        
                            function click_handler(sender, e) 
        
                            { 
        
                                if (sender.CommandName=='DELETE') { 
        
                                    return confirm('<%= MissatgeDinamic("Del1") %>'); 
        
                                } 
        
                            } 
        
                       --> 
        
                                </script> 
        
                            </asp:Panel> 
        
                        </div> 
        
                        <asp:Panel ID="detailsPanel" runat="server"> 
        
                        </asp:Panel> 
        
                        <br /> 
        
                        <radG:RadGrid ID="listGrid" runat="server" PageSize="6" Skin="Glassy" OnNeedDataSource="listGrid_NeedDataSource" 
        
                            OnItemCreated="listGrid_ItemCreated" OnSelectedIndexChanged="listGrid_SelectedIndexChanged" 
        
                            AllowPaging="True" AllowAutomaticDeletes="false" AllowAutomaticInserts="false" 
        
                            AllowAutomaticUpdates="false"> 
        
                            ... 
        
                        </radG:RadGrid> 
        
                    </div> 
        
                </form> 
        
            </body>

and the detailsPanel is where the UserControl will be loaded. A UserControl sample code is:

    
            <script type="text/javascript"> 
        
            function cambiarFecha() 
        
            { 
        
                var input1 = <%=fechaini.ClientID %>; 
        
                var input2 = <%=fechafin.ClientID %>; 
        
                var today = input1.GetDate();  
        
                var thisYear = today.getYear();  
        
                var thisMonth = today.getMonth();  
        
                var thisDay = today.getDate(); 
        
                var maxDate; 
        
                if (thisDay <= 15) { 
        
                   maxDate = new Date(thisYear, thisMonth, 15); 
        
                } 
        
                else 
        
                { 
        
                   maxDate = new Date(thisYear, thisMonth+1, 0); 
        
                } 
        
                input2.SetDate(maxDate); 
        
                input2.SetMaxDate(maxDate); 
        
                input2.SetMinDate(input1.GetDate()); 
        
            } 
        
            </script> 
        
            <table id="Table1"> 
        
                <tr> 
        
                    <td><asp:Label ID="lbl_fechaini" runat="server" /></td> 
        
                    <td><radCln:RadDatePicker ID="fechaini" runat="server" Width="150" DateInput-ReadOnly="true" 
        
                            DateInput-OnClientDateChanged="cambiarFecha" /> 
        
                    </td> 
        
                </tr> 
        
                <tr> 
        
                    <td><asp:Label ID="lbl_fechafin" runat="server" /></td> 
        
                    <td> 
        
                        <radCln:RadDatePicker ID="fechafin" runat="server" Width="150" DateInput-ReadOnly="true" /> 
        
                    </td> 
        
                </tr> 
        
            </table>

and in the behind code I search at my database for if some fields needs more controls, like required field validators. When at database I detect this I create the control I will add and finally I have a line like this:

    
            foreach (Control aux in ctrlAux) 
        
            { 
        
              Controls.AddAt(ctrlAuxPos[idx], aux); 
        
              idx++; 
        
            }

where is the exception I have is throwed.

OnRowContextMenu on Grid with EnablePostBackOnRowClick active

Hello,

do you have any guidelines on how to implement a custom context menu display on grid that enables the post back on row click, meaning on right click on a new row, the postback should be raised, and context menu should be fired afterward.

Many thanks in advance for your answer.
