RadAlert problem

Hi,

I have a user control that includes a button. When button is clicked, I want to show a radalert if some condition is satisfied. How can I do this? I've tried the scenarios at the Calling radalert from codebehind (all versions of RadWindow knowledgebase http://www.telerik.com/support/kb/article/b454K-gtd-b454T-cec-b454c-cec.aspx ...But the radalert isnt displayed.

Thanks.

Multiple javascript errors: Sys undefined, object expected, RadControlsNamespace undefined, ...

Here is our environment info:

.NET framework - 2.0

IDE: VS 2005

Server: Windows Server 2003

Browser: IE 7

Language: C#

Teleric Product: Rad Window 1.9.0

We have around 12 ASP.NET applications running in the web server and we have a requirement to insert a particular text in all the web pages, say for eg. 'Test Server' in red color in our test environment. Since it's not possible to add this manually in all the applications, we decided to write an http module that can insert the text right after the <form> tag. It did worked and we see the text, but we get multiple javascript errors. If we unregister the http module, we don't see any javascript errors. All that the http module does is insert the following html tag after the <form> tag.

<span id='testserver' style="position:absolute; top: 30px; left: 300px; color: red; font-weight: bold; font-size:12pt; z-index:2;">Test Server </span>

We also changed it to div and label tags, but it didn't work.

These are the following javascript errors that we see:

1. 'Sys' is undefined.

2. 'RadControlsNamespace' is undefined.

3. Object exected.

The Http Compression is not enabled in IIS and the 'Check that file exists' checkbox in IIS->VirtualDirectory->.axd edit is checked.

Any help is appreciated.

Thanks.

Error with Grid and Sample From Knowledge Base

Hello all,

I have been working on this for a day or so now and can't seem to resolve the problem. So I am coming to the experts. :) I have just recently purchased the Rad controls and I am loving them. But as I was trying to use the RadGrid from the ASP.NET, I have run into a snag. I wanted to use the Client-Side select to update another grid from the server side. So I did what I thought was right and used some javascript and did a __doPostBack(), but kept getting an error. So I searched and searched and finally found a knowledge base article that explains how to do it (see PostBackFromClientEventsCS.zip at bottom of http://www.telerik.com/support/kb/article/b454K-kGj-b454T-cfD.aspx). I had to massage this a little to work with the 3.5 frame work and the new namespaces, but the everything else should be the same. Anyway, when I run this, I get the same error as I do on my website:

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

Configuration:
VS2008
telerik.web.ui.dll version 2008.2.826.35
.NET 3.5

I will gladly fwd an updated version of the sample website if someone could please look into this.

Thanks in advance,
Lee

ToolTip related? - Invalid postback...

Hi!

I'll get right to the point. I'm having problems with the ToolTip Manager. I have a RadGrid and to every label in one of the rows of the grid I add a tooltip (which loads on demand). What happens is I move the cursor over a label and the tooltip shows as expected. I click on whatever button on my page which generates a postback. Once again I move the cursor over a tooltip which again opens with no problem...and then.. my problem starts. In the next step if I click on whatever button or move the cursor over another label in order to show the tooltip, I get the following asp.net error:

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. (...)

here is the code of the relevant methods:

    
             protected void Page_Load(object sender, EventArgs e)

Trouble binding Label field to Column

I need to display what should be a pretty basic Pie Chart, but am having trouble with the Labels.

The data is all coming from a SQL database, and it's only two columns. The "Chart Label" is a pre-calculated Label that I'd like to use on each slice of the pie chart. Occurences are, the values that the chart will be.... charting....

--------------------------------------
Occurrences     |    Chart Label
--------------------------------------
2                      |   Item Label 1 (2)
5                      |   Item Label 2 (5)
6                      |   Item Label 3 (6)
2                      |   Item Label 4 (2)
3                      |   Item Label 5 (3)

So in my ASPX code, I have the following:

    
            <telerik:RadChart ID="RadChart1" runat="server" DataSourceID="SqlDataSource1" DefaultType="Pie" Skin="WebBlue" IntelligentLabelsEnabled="True" AutoTextWrap="True" AutoLayout="True" SeriesOrientation="Horizontal"> 
        
                    <Series> 
        
                        <telerik:ChartSeries DataLabelsColumn="ChartLabel" DataYColumn="Occurrences" Name="Occurrences" Type="Pie"> 
        
                            <Appearance> 
        
                                <LabelAppearance Distance="15"> 
        
                                </LabelAppearance> 
        
                                <Border Color="73, 86, 101" /> 
        
                                <TextAppearance TextProperties-Color="140, 140, 140"> 
        
                                </TextAppearance> 
        
                                <FillStyle FillType="ComplexGradient" MainColor="94, 117, 142"> 
        
                                    <FillSettings> 
        
                                        <ComplexGradient> 
        
                                            <telerik:GradientElement Color="94, 117, 142" /> 
        
                                            <telerik:GradientElement Color="116, 138, 162" Position="0.5" /> 
        
                                            <telerik:GradientElement Color="139, 160, 183" Position="1" /> 
        
                                        </ComplexGradient> 
        
                                    </FillSettings> 
        
                                </FillStyle> 
        
                            </Appearance> 
        
                        </telerik:ChartSeries> 
        
                    </Series> 
        
            ... 
        
            </telerik:RadChart> 
        
            ... 
        
            <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>" 
        
                    SelectCommand="SELECT COUNT(*) AS [Occurrences], incidentCode + ' (' + CAST(COUNT(*) AS nvarchar) + ')' AS [ChartLabel] FROM Incidents GROUP BY incidentCode"> 
        
            </asp:SqlDataSource> 
        
            ...

Note that I'm trying to bind the label text to the "Chart Label" field. Am I going about this in the wrong way, because it is not working... instead, the label is displaying the value in the "Occurrences" field.

Even if I go into the Chart Wizard to set the Label field to "Chart Label" - nothing happens and the value is not saved.

Thanks!

Client side seems broken

I'm pretty new to Telerik, so I'm sure I've done something wrong here, but...

I can get the grid to work in my app. Examples of client side failure include no response when I mouse over a row and No postback on a row click. Strange thing is that paging seems to be working.

I've tried and failed at reproducing this behavior in a sample app. Could it be that I've added the script manager to the master page & not the child page? Does it need to be added to both? Is this a scripting failure or am I unable to figure out how to set the "react to a mouse over" setting?

My goal is pretty simple: Display a list of names & do an Ajax update in response to clicking on a row. I've reproduced this goal in the sample app, but can't get the real app to react to client side actions. Without the mouise over feedback the client will not know they can click on the row.

[Solved] Column visibility selection

Hello,

I've been looking a simple way of obtain something similar to this http://www.extjs.com/deploy/dev/examples/grid/array-grid.html and get a column menu to select which columns to display and the column ordering.

Will Telerik WebGrid support this in the next future? is any way to implement it in a simple way with the actual webgrid control?

Thanks a lot for your answer!
