RadGrid Client Side Add/Update/Delete
Hi,

I have a Radgrid with add/update/delete custom buttons on top of the grid. I can invoke the clientside edit of a row using this script on rowclick or rowdblclick.

 editedRow = eventArgs.get_itemIndexHierarchical();
 $find("<%= RadGrid1.MasterTableView.ClientID %>").editItem(editedRow);

However, I am unable to persist the changes to the server when I use

 $find("<%= RadGrid1.MasterTableView.ClientID %>").updateItem(editedRow);

Can anyone explain what exactly happens when updateItem is called. Does the UpdateCommand get fired on the server?

Here is my code

The Script BLOCK :

 <telerik:RadScriptManager ID="ScriptManager" runat="server" /> 
         <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

                <script type="text/javascript">
                    
                    var hasChanges = false;
                    var editedRow;
                    var editedRowId;
                    var editButton;

                  
                    
                    function RowClick(sender, eventArgs)
                    {

                        editedRow = eventArgs.get_itemIndexHierarchical();
                        var grid = $find("<%= RadGrid1.ClientID %>");
                        var masterTable = grid.get_masterTableView();
                        if (editedRow && hasChanges) {
                            if (confirm("Update changes?")) {
                                hasChanges = false;
                                 $find("<%= RadGrid1.MasterTableView.ClientID %>").updateItem(editedRow);
                                editButton.set_enabled(true);
                               
                            }
                            else {
                                hasChanges = true;
                            }
                        }
                       
                  }


                  function onToolButtonClick(sender, args) {
                      editButton = args.get_item();
                      var commandName = editButton.get_commandName();
                      var grid = $find("<%= RadGrid1.ClientID %>");
                      alert("Selected Item Count: " + grid.get_selectedItems().length);
                      switch (commandName)
                      {
                      case "AddSelectedItem":
                            
                              grid.get_masterTableView().insertItem();
                              break;
                          case "EditSelectedItem":
                              editButton.set_enabled(false);                            
                              grid.get_masterTableView().editItem(editedRow);
                              editedRowId = editedRow;
                              hasChanges = true;
                              break;
                      case "DeleteSelectedItem":                       
                          editButton.set_enabled(!confirm('Delete selected item?'));
                          break;   
                      }
                  }

                
                </script>

Image path problem
Hello!

I've stumbled across a problem with images being moved around, by selecting and dragging them in the editor in Firefox. Whenever I do this, the image url gets changed – two dots are being added in front of the file path. So, instead of having the url read like this: src="/image-file.jpg" (which is what we're intending) it becomes src="../image-file.jpg" which in turn makes the image disappear once the page is saved & published through our cms tool.

Any solution to this?

[Solved] telerik is undefined
I have something very strange.
I get the javascript error telerik is undefined, and only for IE6.

It happens only to the tree object, and on one page it works wel, but on another page I get this error, and the tree is unaccessable.

Is there something where and how I can register the webresource.axd?

When I'm looking with fiddler, I don't see the resource loading on my second page, but it is loading on the first page.

I've already searched in your forum, but there is not any solution described. So please help!

Thanks in advance

Unknown server tag telerik:RadCaptcha
I`m currently using RadControls for ASPNET AJAX Q1 2009, and wanted to try the RadCaptcha control in one of my forms. I added the handlers in web.config and tried to add the control to my page(usercontrol). Intellisense inVisual Studio could not find it (Element RadCaptcha is not a known element). I added the code from one of the examples

<

 

telerik:RadCaptcha ID="RadCaptcha1" runat="server" ErrorMessage="Page not valid. The code you entered is not valid." ValidationGroup="Group">

 

 

 

 

 

 

</telerik:RadCaptcha>

 

 

 

 

 


And all it does is throw an Parser Error: "Unknown server tag 'telerik:RadCaptcha'."

Is this control not part of ASPNET AJAX Q1 2009? or am I doing something wrong here?

Set width of RadPanelBar in a RadPane when a scrollbar appears
Hi. Is there a way to get a RadPanelBar to resize its width when the RadPane that its in shows a vertical scroll bar? Its always sized to the width of the RadPanel that its in, but if a scrollbar is showing, it covers up the right hand side exspand / collape arrow. Yes, I know you can click anyhere on the main RadPanelItem, but it would look better if its sized properly.
   
How would I accomplish this in java script? Can I detect when a RadPane has a scrollbar showing and what the width of that scrollbar is? Is it possible to even set the width of a RadPanelBar on the client side? I get a error when I call set_width() on its client side object,
Thanks,
Brian

'Button' must be placed inside a form tag with runat=server
Full Error: Control 'RadGrid1_ctl00_ctl02_ctl00_ctl04' of type 'Button' must be placed inside a form tag with runat=server

Details:
I'm placing a radgrid in a usercontrol, the usercontrol will be placed on an mvc page 6 times.  The radcontrol works if it is alone on a page (not int a user control) using the following code:
<body>
    <form runat="server">
    <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
    </telerik:RadScriptManager>
    <telerik:RadGrid ID="RadGrid1" AutoGenerateColumns="false" runat="server">
        <MasterTableView>
            <Columns>
                <telerik:GridBoundColumn DataField="region" DataType="System.String" HeaderText="regionheader" />
                <telerik:GridBoundColumn DataField="playCount" DataType="System.Int32" HeaderText="playcountheader" />
            </Columns>
        </MasterTableView>
        <ClientSettings>
            <DataBinding Location="/ASP/GridWS.asmx" SelectMethod="GetData" SelectCountMethod="GetCount" />
        </ClientSettings>
    </telerik:RadGrid>
    </form>
</body>

However I get the error when I attempt to place the grid in the control on the page.  If I move the <form> tag from the page to the control it will render without the error, but I need to have the form on the page as there are other controls that need to post, and basically because it seems like bad practice.

RequiredFieldValidator with RadComboBox Under DataGrid

I am working with migration project.  I have converted the asp ComboBox to  Rad ComboBox. RadComboBox is under DataGrid. asp:RequiredFieldValidator is used for validation. It was working with asp ComboBox but not working with RadComboBox. One of the reason I identify that RadComboBox validate the text not value.

I try with custom validator but it is not working because the RadComboBox is under DataGrid.

 

Please give me proper solution. Thanks.

 

 

 

<asp:DataGrid ID="dgLesson" runat="server" CssClass="dataGridTable" Width="100%" .........

<Columns> 

< asp:TemplateColumn HeaderText="Sequence Number">   

<ItemTemplate>

 <asp:Label ID="lbSequenceNumber" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "SequenceNumber") %>'>  

</asp:Label>

 </ItemTemplate>

 <FooterTemplate>  

<telerik:RadComboBox ID="ddAddSequenceNumber" runat="server">

</telerik:RadComboBox>  

<asp:RequiredFieldValidator ID="rfvAddSequenceNumber" runat="server" ControlToValidate="ddAddSequenceNumber"

ErrorMessage="Required" Display="Dynamic"></asp:RequiredFieldValidator>  

</FooterTemplate>
