Slider in ajax modalpopup

Hi,

I have a page with a modal popup (extender) on it. When opening the modal popup I dynamically load a usercontrol in the popup which has three radsliders on it. The only problem is that they don't work, they do not render correctly as well. I fixed the faulty rendering with the redraw function but i still cannot move the sliders.

Any help is apreciated.

RadAjaxManager Issue in Master/Content Page

I have Master Page and a Content page and I am trying to ajaxify content page. I am using RadAjaxManager to do that.

AS soon as I drop a RadCombobox on the content page with AutoPostback=True and use it with the RadAjaxManager as the control that updates other controls, I get error :

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

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

As you can see my script code is inside the RadCodeBlock and I have very simple master page. Also, I have noticed that if I used and other standard ASP.NET control that causes the postback and I use it RadAjaxManager, I don't get the error mentioned above. I would appreciate if you would let me know a workaround to this problem. This is very urget and a quick response will be appreciated.

I am using RadControls for ASP.NET AJAX 2009 Q1.

Thanks,

Selecting RadComboBox value in GridTemplateColumn

Hi all,

I'm sure you understand my code beneath, but how could this be done better? Not really like this "selection-hack"...

GridTemplateColumn:

    
            <telerik:GridTemplateColumn HeaderText="<%$ Resources:LanguageWeb, OrderLine_Paragraph %>" 
        
                UniqueName="ParagraphId" HeaderStyle-Width="200px"> 

                <ItemTemplate>  
        
                    <telerik:RadComboBox runat="server" ID="CbParagraph" OnInit="CbParagraph_Init" ToolTip='<%# Bind("Paragraph.id") %>' /> 
        
                </ItemTemplate>  
        
            </telerik:GridTemplateColumn>

The combobox items is loaded in the OnInit event, and selection done in the ItemDataBound on the RadGrid like this:

    
            protected void RadGrid_ItemDataBound(object sender, GridItemEventArgs e) 
        
            { 
        
                if (!(e.Item is GridDataItem)) return; 
        
                var gridItem = (GridDataItem)e.Item; 
        
                var cbParagraphControl = gridItem.FindControl("CbParagraph"); 
        
                if (cbParagraphControl is RadComboBox) 
        
                { 
        
                    var cbParagraph = (RadComboBox) cbParagraphControl; 
        
                    cbParagraphcbParagraph.SelectedValue = cbParagraph.ToolTip; 
        
                    cbParagraph.ToolTip = ""; 
        
                } 
        
            }

Any ideas?

Cheers, Ahrensberg

Combobox and Autofiltering

First, I think I have found a bug, a little glitch in fact.

http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/filteringcombo/defaultcs.aspx

Select the combobox, open the options, double esc it. Next time you open it, the list will be blank (you have to delete the text inside, usability fail). Something about the "emptytext" and the filtering action.

The same bug hapens here, but a little bad, the list dont open at all:

<telerik:RadComboBox ID="RadComboBox1" runat="server"
AllowCustomText="False"
Filter="Contains"
EmptyMessage="Select one...">
<Items>
  <telerik:RadComboBoxItem Text="" Value="None" />
  <telerik:RadComboBoxItem Text="test1" Value="0" />
  <telerik:RadComboBoxItem Text="test2" Value="1" />
  <telerik:RadComboBoxItem Text="test3" Value="2" />
</Items>
</telerik:RadComboBox>

Second, im trying to build a very simple combobox, with some options inside, AllowCustomText setted to false, and contains filtering on. If the user enter some customtext, and click outside the combobox, or just press enter, I do expected the combo to come back to "emptytext" property, because customtext its not allowed. Do i miss understood the property, is it valid for filtered combos, or Im missing something?

Third, I do live in a country (Brazil) that uses accents, like french. Is there a property to ignore accents in the filter? If not, I think its a good idea for the future.

All the best,
André.

Grid Export to Excel file name shows junk characters like %.

Hi,

In my current web application I am extensively using export functionality of rad grid for excel file.
But when I click on "Open" button of "File Download" dialog fix the opened file shows up with junk charactes like % in its name even though the "File Download" dialog displays correct name.
e.g. file name - "%43%75%72%72%65%6e%74%20%4d%61%72%6b%65%74%20%4f%74%68%65%72%20%43%6f%6d%6d%6f%64%69%74%79%20%50%72%69%63%65 1 .xls"
I haven't changed the export code, just setting up default properties in ASPX for export.

I will appreciate the help at earliest.
Thanks,
Avi
