I am using a rad tool tip who's values are set in a user control. I am using an 'OnAjaxupdate' method to load the usercontrol and display the tooltip.

But when i hover the mouse over my image icon (targetcontrol of the radtooltipmanager); i get a pop up window prompting
"radToolTipManager response error. An unknown server error has occured. The status code returned is 500"

Looks like this is happens either if I link a css class in the loaded user control or if I add a style inside user control. Look at my below code inside a user control

    
            <style type="text/css">  
        
                 .label  
        
                    {  
        
                        color: Blue;  
        
                        font-family: Tahoma;  
        
                        font-size: 1em;  
        
                        font-weight:bold 
        
                    }  
        
                 .value  
        
                    {  
        
                        color: black;  
        
                        font-family: Tahoma;  
        
                        font-size: .9em;  
        
                    }  
        
            </style>

    
            <asp:UpdatePanel ID="pnl" runat="server" UpdateMode="Conditional">  
        
                <ContentTemplate> 
        
                    <table border = "0"  align = "center" width = "100%" > 
        
                        <tr> 
        
                            <td><asp:Label ID="lblContent" runat="server" Text="Content File:" class = "label"></asp:Label></td>  
        
                             <td><asp:Label ID="lblContentUrl" runat="server" class = "value"></asp:Label></td>  
        
                        </tr> 
        
                        <tr> 
        
                            <td><asp:Label ID="lblTotalLinks" runat="server" Text="Total Links:" class = "label"></asp:Label></td>  
        
                            <td><asp:Label ID="lblTotalLinksValue" runat="server" class = "value"></asp:Label></td>  
        
                        </tr> 
        
                         <tr> 
        
                            <td><asp:Label ID="lblVersion" runat="server" Text="Version:"  class = "label"></asp:Label></td>  
        
                             <td><asp:Label ID="lblVersionValue" runat="server" class = "value"></asp:Label></td>  
        
                        </tr> 
        
                        <tr> 
        
                            <td><asp:Label ID="lblCheckedOut" runat="server" Text="Checked Out:" class = "label" ></asp:Label></td>  
        
                            <td><asp:Label ID="lblCheckedOutValue" runat="server" class = "value"></asp:Label></td>  
        
                        </tr> 
        
                        <tr> 
        
                            <td><asp:Label ID="lblCreatedOn" runat="server" Text="Created On:" class = "label" ></asp:Label></td>  
        
                            <td><asp:Label ID="lblCreatedOnValue" runat="server" class = "value"></asp:Label></td>  
        
                        </tr> 
        
                        <tr> 
        
                            <td><asp:Label ID="lblLastModifiedOn" runat="server" Text="Last Modified On:" class = "label"></asp:Label></td>  
        
                            <td><asp:Label ID="lblLastModifiedOnValue" runat="server" class = "value"></asp:Label></td>  
        
                        </tr> 
        
                    </table> 
        
                </ContentTemplate> 
        
            </asp:UpdatePanel>

What does the error mean?

My code files are
1.usercontrol.ascx (defined the user control),
2.usercontrol.ascx.cs(defined labels and textboxes as properties whose values are set in the default.aspx.cs page),
3.default.aspx (web page) and
4.default.aspx.cs(code behind having 'OnAjaxUpdate' method used for loading usercontrol and populationg the tooltip with values)

Also i am using an external css file to manage the look of the tooltip. But it has no effect on the tooltip content. Sohow can i change the font-size , color etc of the content inside the tooltip by using CSS or inline styles?

Any help in this is highly appreciated...

[RadInputManager/RegExpTextboxSetting] After validation my controls are all the time cleared

Dear Telerik Community,

Currently i am developing an dynamic field initializer where validation expressions are used. Those expressions are set dynamicly in de codebehind attached to a textbox for example. My problem lays in the option that i sometimes don't want to set the validation expression in the regexptextboxsetting for example. When i leave the validationexpression empty the textbox will validate but on the wrong way. It automaticly deletes the value of the textbox and gives an warning sign that it is not correct.

My question is, can i set the validationexpression empty so that no validation is set and that it wont validate the control? In the following code snippit you will see what i have done:

/// <summary>

/// Generates the textual control.

/// </summary>

/// <param name="fieldDefinition">Fielddefinition that holds the data that needs to be set on the control.</param>

/// <returns>A textual control based on a textbox.</returns>

private TextBox textualControl(ServiceObjectFieldDefinition fieldDefinition, RadInputManager inputManager)

{

string controlId = string.Format("dynamicFieldControl-{0}", fieldDefinition.Id);

this.dynamicFieldControlSequenceIds.Add(controlId);

RegExpTextBoxSetting textualValidationSetting = new RegExpTextBoxSetting();

textualValidationSetting.BehaviorID = controlId;

TextBox textualTextbox = new TextBox();

textualTextbox.ID = controlId;

if (fieldDefinition.Mandatory)

textualValidationSetting.Validation.IsRequired = true;

if (fieldDefinition.MaxLength != null)

textualTextbox.MaxLength = Convert.ToInt32(fieldDefinition.MaxLength);

if (!string.IsNullOrEmpty(fieldDefinition.DefaultValue))

textualTextbox.Text = fieldDefinition.DefaultValue;

if (fieldDefinition.DefaultValueFixed)

textualTextbox.Enabled = false;

textualValidationSetting.ValidationExpression = fieldDefinition.MinLength != null ? string.Format("{{0},}", Convert.ToInt32(fieldDefinition.MinLength)) : "{0,}";

TargetInput textualValidationInput = new TargetInput(controlId, true);

textualValidationSetting.TargetControls.Add(textualValidationInput);

inputManager.InputSettings.Add(textualValidationSetting);

this.dynamicControls.Add(textualTextbox);

return textualTextbox;

}

Maybe my thougts are wrong :-) so can somebody help me?

Kind regards,
Michiel Peeters

Ajaxify a control using Regular control and User Control

Hi,
I have a Rad Grid, Button1 and a User control in a page. I want to set Button1 (from Page) and Button2 (from User control) as trigger control to RadGrid . On clicking any of these buttons RadGrid should be updated. I want to use Rad Ajax manager to set the Updated Control and Ajaxified Control.

I found couple of samples where control in UserControl updates updates a textbox in parentpage or a control in parent page updates a label in user control but couldnot find any example where two different controls in parent page and user control act as a trigger to update a single control. How can I implement the above objective?

Sincerely,
Prava

No InsertItemTemplate in RadGrid?

Hello,

I have a RadGrid that I'm attempting to use in form editing on. I'm currently using the following GridTemplateColumn. The problem is that what I really need is an InsertItemTemplate like what asp:DetailsView has. This is because I want the Status field to be editable in a RadComboBox on insert, but, non-editable and displayed in a label on edit. Does anyone know if this is possible in RadGrid? I'm assuming that I'll probably have to handle an event and adjust the visibility of fields based on whether it's in insert or edit mode? The problem is that I don't know what event I should use to do this and I also don't know how to lookup the control. I'm assuming I'll probably have to use FindControl() and maybe use the RowIndex to find the proper row in the grid or something. Any help would be greatly appreciated.

<telerik:GridTemplateColumn HeaderText="Status" SortExpression="Status">
