I have a RadAjaxPanel that contains a table I am trying to update through the C# code. What happens is the user will first buy all the items, and click "Confirm Purchase". The original panel will go invisible, and then the final radajaxpanel will become visible. At that point, a method in C# will be called to populate the table inside with the final cart. However, in my C# code, when I try to add a newly created row to the table, I get an error that the table doesn't exist. Here's the code: <telerik:RadAjaxPanel ID="PanelCompletePurchase" runat="server" Visible="false">
    <h4>Complete Purchase</h4> 
    <table id="ReceiptTable">
        <tr>
           <th>Quantity</th>
           <th>Product</th>
           <th>Rate</th>
           <th>Price</th>
        </tr>
    </table>
    <asp:Label ID="Message" runat="server" ForeColor="Maroon"></asp:Label>
                <br />
                <asp:Label ID="Response" runat="server" ForeColor="maroon"></asp:Label>
                <br />
                <asp:Label ID="Debug" runat="server" forecolor="maroon"></asp:Label>
</telerik:RadAjaxPanel>

In my C# code, I doReceiptTable.Rows.Add(someCreatedRow);ReceiptTable is red and it shows unknown entity. How do I access the html table inside of the RadAjaxPanel? My Labels update just fine

Why below code is not working. I am try to convert html to pdf. "radEditor.ExportToPdf()" line of code given error "Object reference not set to an instance of an object at Telerik.Web.UI.Editor.Export.RadEditorExportTemplate.Export()" 
       static void Main(string[] args)
        {
            RadEditor radEditor = new RadEditor();
            radEditor.Content = "<div>Hello</div>";
            radEditor.ExportContent += radEditor_ExportContent;
            radEditor.ExportToPdf();
        }

        static void radEditor_ExportContent(object sender, EditorExportingArgs e)
        {
            string path = "C:/tmp/NewFile.pdf";
            if (File.Exists(path))
            {
                File.Delete(path);
            }

            using (FileStream fs = File.Create(path))
            {
                Byte[] info = System.Text.Encoding.Default.GetBytes(e.ExportOutput);
                fs.Write(info, 0, info.Length);
            }

        }

Hi

I have a fairly standard radgrid with masterview and detail tables.

When editing an item at the top level (parent item), how would I go about auto-expanding the child rows and putting the parent and child rows in edit mode?

Thanks
David

I have added a ComboBox control to the AdvancedForm.ascx.  When the advanced form is displayed, the selected item in the combobox is not shown.  Stepping through the code, I can see radDropDestination.SelectedIndex = dest.Index; properly being set.  How do you set the SelectedIndex for the ComboBox or properly bind the Combobox so the selected item is shown when the AdvancedForm.ascx is displayed?  




Code behind for AdvancedForm.ascx


From the default.aspx

We have an issue with the editor in Google Chrome. When the editor gets loaded the cursor does not look like it is in the editor box. If you click in the box then the cursor is there and you can start typing but you get a blank line at the top that you cannot remove. Our clients are complaining about this :)

It does not do this in Firefox. If you do the above and then switch to html view you see "<p>text</p>". If you do the same in FireFox you see nothing in html view. Ironically if you switch to html mode in Google first and then switch back that does not happen. 

How can we fix this so our clients are not unhappy?

Hi Danail,

When a chart has no data present it would be nice if the chart had a built in way to display a custom message indicating no data.  Obviously you can detect this from the code behind and then display the message over the top of the chart but a built in mechanism would be nice.  Even nicer would be some way to have a nice grayed out chart along with the text.

Could that be added to the feature request list please?

Regards

Jon

Hello

We have a User Control (.Net, c#) that uses RadComboBox with MarkFirstCharacter=true and Filter="Contains".
When we started typing in the box, it would filter out using the characters as we type them.
It used to work in IE9 and IE10.  But now with IE11, it has stopped working. 
It only uses the first character.  We can see that it has found all instances of items that use that character but as soon as we type the second character, it stops filtering.  It works in Compatibility mode and also in Firefox.

Any ideas?

Thank you

I am attempting to iterate through a RadGrid and check the values of the checkbox inside a template column.

So far what I have is the following: 


I get the error, "Reference to a non-shared member requires an object reference." On the line For Each myRow As GridDataItem In myGrid.Items. I have googled this, but come up with 0 results that either worked or made sense for me/my project. I am not quite sure how to get rid of this. I am pretty certain I am doing the iteration correctly. I have referenced a few posts on the Telerik forums as well as StackOverflow.

I have a checkbox defined as

<telerik:RadButton ID="checkbox1" runat="server" Text="testing" ButtonType ="ToggleButton" ToggleType="CheckBox" OnClientClicked="checkbox1_ClientClicked"></telerik:RadButton>

What I want to do in the ClientClicked event is only check the box (and uncheck a different checkbox) when the user selects OK. Everything else seems to work fine but even though the last thing I do in the "ok" case is .set_checked(false) the box remains checked. Here is the javascript:

            function checkbox1_ClientClicked(sender, eventArgs) {
                var checkbox1 = $find('<%=checkbox1.ClientID%>');
                function CallbackFn(arg) {
                    if (arg) {
                        var checkbox1 = $find('<%=checkbox1.ClientID%>');  // I know I probably don't need this, just being safe
                        var checkbox2 = $find('<%=checkbox2.ClientID%>');
                        checkbox1.set_checked(true);
                        checkbox2.set_checked(false);
                    }
                    else {
                        checkbox1.set_checked(false);
                    }
                }
                if (checkbox1.get_checked()) {
                    return radconfirm("warning text", CallbackFn, 330, 150, null, "title");
                }
            }

I've also tried the ClientCheckedChanged and ClientCheckedChanging events with similar results. What obvious, basic thing am I missing? 8^)
