I have a data set that I want to present as a line chart.

I've specified the x axis labels as one of the columns, a 2nd column is the datagroupcolumn and the 3rd is the value.

The issue arises because the xaxis appears to be the distinct values from the xaxis column however for some of the groups these rows don't exist and aren't plotted this results in some series the plots don't line up with the x axis correctly.

imagine this data set

x axis    Group    Value
1            1            1
2            1            2
3            1            2
4            1            2
3            2            10
4            2            11

You will note that the group 2 doesn't have any values for x values 1 and 2. The chart however seems to plot by index value and not by x axis value. i.e. at the nth position of the axis it plots group[i].value[n], so in the data above for xaxis 1 we get Group 1 =1 and Group2 = 10.

Apart from filling in all the gaps in the dataset what can be done.

Problem with hierarchy and detail tables

Hello,
I have a rad grid in a usercontrol with 3 levels of hierarchy as shown bellow,

    
            <rad:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" OnItemDataBound="OnGridItemDataBound" 
        
                EnableViewState="true">  
        
                <MasterTableView DataSourceID="SqlDataSource1" DataKeyNames="SpecialismeNaam" AllowMultiColumnSorting="True" 
        
                    EnableViewState="true">  
        
                    <DetailTables> 
        
                        <rad:GridTableView DataKeyNames="CareType" DataSourceID="SqlDataSource2" Width="100%" 
        
                            runat="server">  
        
                            <ParentTableRelation> 
        
                                <rad:GridRelationFields DetailKeyField="SpecialismeNaam" MasterKeyField="SpecialismeNaam" /> 
        
                            </ParentTableRelation> 
        
                            <DetailTables> 
        
                                <rad:GridTableView DataKeyNames="Indicator" DataSourceID="SqlDataSource3" Width="100%" 
        
                                    runat="server">  
        
                                    <ParentTableRelation> 
        
                                        <rad:GridRelationFields DetailKeyField="CareType" MasterKeyField="CareType" /> 
        
                                    </ParentTableRelation> 
        
                                </rad:GridTableView> 
        
                            </DetailTables> 
        
                        </rad:GridTableView> 
        
                    </DetailTables> 
        
                </MasterTableView> 
        
            </rad:RadGrid>

in the OnItemDataBound event handler, I replace the value of specific column cells with a suitable image,

    
                    protected void OnGridItemDataBound(object sender, Telerik.WebControls.GridItemEventArgs e)  
        
                    {  
        
                        GridDataItem item = e.Item as GridDataItem;  
        
                        if (item == null)  
        
                        {  
        
                            return;  
        
                        }  
        
                        if (item["Trend"] == null)  
        
                        {  
        
                            return;  
        
                        }  
        
                        int trenValue;  
        
                        if (!int.TryParse(item["Trend"].Text, out trenValue))  
        
                        {  
        
                            return;  
        
                        }  
        
                        // Display image  
        
                        item["Trend"].Controls.Add(GetCellArrowImage(trenValue));  
        
                    }

the images are displayed well, but the problem is when I expand a detail table, the images in the parent table disappear and appears in the child table, I want them to be displayed in all hierarchy levels.

tab control and radwindow

Hi,

I have a main page, which has a tab strip wrapped within the ajax panel. The tab strip has 4 tabs. Each page view of tab is a user control. In my first control (first tab), i have added a RadWindowManager, which has only one RadWindow with client call back function, offelementid, navigate url, reload on show set to true, and bahaviors - close and move. The navigate url of the rad window is a page in our site. When I first load the main page and click on a button to open the radwindow, it works as designed. Everything is great. Now I navigate to the next tab by click a button on the first tab user control ( the button is registered as post back control) and back to my previous tab. Now I click on the button to open the rad window, the window does not behave the same way, it showed initially- which means, the behaviors has refresh, minimize, maximize etc and it does not refresh on show.

Please suggest any ideas.

Thank you very much in advance.

Thanks
Manohar

Textbox in Grid FormEdit Weird behavior

Hello

I have a grid with 3 columns (Date, Qty, Note)
I use a FormTemplate to Edit.
Everything works fine. However, when I enter the character < follow by a letter such as <c in the textbox and click update, it causes an error on the Internet Explorer page.

Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500

It also gives the error on Inserts
Is this a bug, or am I doing something wrong?

Edit: Just tested this out in one of your online Grid Edit demos. It causes to give an error saying the page is not found.
