Slider layout options, disable close icon?

I removed the dock icon with the EnableDock property set to false.

1. How can I disable the close icon?
2. how can I set the height of the slider that expands to be exactly large enough to fit the content that is there. The content is dynamic so it won't be the same each time so I can't set a fixed height.

Workflow Data Entry Using PanelBar

Masters and Experts,
I would like to implement a workflow form using the PanelBar control. I wanted to check here and see if it's possible before I put the development effort into it. What I would like to accomplish is creating a user control that would display in a RadWindow that will function as follows;
Panel1:
User Selected Search Criteria
Search / Move Next button (if results were found, If not message user)
Panel2
RadGrid containing the results from the Search from Panel1. User would select the record they need for primer data for their new entry on Panel3
Move Next Button
Panel3
ReadOnly data items from Panel2s selection and editable user entry data fields
Save Button

If it's possible for the control to handle that type of data manipulation would you know of any samples I could review as reference.

Thanks,
Tim

Change text of custom linkbutton in CommandItemTemplate

I have the following in the CommandItemTemplate tag:

<
 
CommandItemTemplate>
 
    <table width="100%">
 
        <tr>
 
            <td align="left">Third Party Mismatches</td>
 
            <td align="right">
 
                <asp:LinkButton ID="showFilter" runat="server" CommandName="DisplayFilter"
 
                    Text="Filter">
 
                </asp:LinkButton>
 
            </td>
 
        </tr>
 
    </table>
 
</
 
CommandItemTemplate>

 
What i want to do is when the user clicks on the showFilter link it will display or hide the folter depending on if it is shown already or not. I have that part working. What I can't get is to change the text to "Show Filter" if the filter is hidden and "Hide Filter" if it is shown.

I have the followinfg code but it isn't working.

            Protected Sub GrdThirdParty_ItemCommand(ByVal source As Object, _  
        
                                     ByVal e As GridCommandEventArgs) _  
        
                                     Handles GrdThirdParty.ItemCommand  
        
                    If e.CommandName = "DisplayFilter" Then 
        
                        Dim lnkButton As LinkButton = CType(e.Item.FindControl("showFilter"), LinkButton)  
        
                        If GrdThirdParty.AllowFilteringByColumn = False Then 
        
                            GrdThirdParty.AllowFilteringByColumn = True 
        
                            lnkButton.Text = "Hide Filter"  
        
                        Else 
        
                            GrdThirdParty.AllowFilteringByColumn = False 
        
                            lnkButton.Text = "Show Filter" 
        
                        End If 
        
                        GrdThirdParty.MasterTableView.Rebind()  
        
                    End If 
        
                End Sub 
        
Any ideas?

Thanks for the help.

Set content text color in code behind

Hi,

Here is our scenario. We have a screen where users need to add their comment in a text editor. What we would like to achieve is that the color is fixed based on the user role.
We have tried the following code but without any luck:

RadEditor tbOpmerkingen = editedItem.FindControl("tbOpmerkingen") as RadEditor;
tbOpmerkingen.ForeColor = System.Drawing.Color.Blue;

and

tbOpmerkingen.ContentAreaCssFile = "~/App_Themes/easecc/Test.css";

css looks like
.RadEContent
{
color: Blue !important;
}

and

Literal styleSheet = (Literal)this.Master.FindControl("styleSheet");
styleSheet.Text = ".RadEContent{color: Blue !important;}";

with in the masterpage header section

<style>
<asp:Literal id="styleSheet" runat="server"></asp:Literal>
</style>

Any help on this issue is appreciated.

Exceptions thrown by page show as Javascript error

I am working on several pages that have Rad controls. When I run these pages in the Visual Studio debugger and my server-side code throws an exception, it always shows up as if it is a Javascript exception. (See the attached screenshot). I believe this happens whenever I have a RadAjaxPanel on the page.

This means it takes me a very long time to track down the source of the exception. Since I don't get to see the standard ASP.Net exception message, I don't get to see the file name and line number of where the exception was thrown.

Is there any way to disable this behavior, and show the standard ASP.Net exception message instead?

RadGrid with Upload In grid Generates PageRequestManagerServerErrorException

I have a RadGrid with an upload copied from the example. When the cancel, edit or delete buttons are pushed I get a Microsoft JScript runtime error with the following data:

Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

I have tried several work arounds but none of them work.

Filter Operator dropdown not displaying at the expected location

Hello,

Please take a look at the attached screenshot. When I click on the filter operator selector (this is, the place where I can pick if I want the field to be EqualTo, NotEqualTo, GreaterThan, etc.) the dropdown centers itself in he middle of the screen, instead of showing right down the Filter component expression being entered. This happens also when I click on the Field selector. Is this a CSS issue? please advice, thanks!

500 error when selecting an item

I have a RadComboBox that is populated on demand with a web service with items based off what the user types. It works fine with a basic string as the text value when I add a RadComboBoxItemData object to the array that I pass back with the web service. I would like to have a template format when the RadComboBox is opened though. For example, a name with a formatted address that is a different color than the title and someone dynamically formatted based on what fields exist for each record. I didn't see an example, so I tried to generate a few HTML tags to handle that. It displays fine when expanded, although it has the tags for the textbox area. It would be nice if I could just have the name in the textbox, but the name and formatted address when the RadComboBox is open. When I select one of the items I get a server 500 error. In the event viewer, it states that "A potentially dangerous Request.Form value was detected from the client ". Is there some other way that I should be doing this? Is the functionality I am looking for even possible right now with the RadComboBox?
