Strange Behavior in Hierarchical DataGrid

I am having a issue displaying data from a dataset to a Hierarchical RadGrid. I have created a small solution that will display the issue, but I have no way of posting it. the solution is a n-teir solution and a website that is built to use user controls to build and display the data. I am defining the hierarchical datagrid in a .cs class in my controls folder of the website.

Data: I have 3 rows of data in the Parent and each row has child records.

Row 1 displays properly
Row 2 displays properly
Row 3 does not display any data until you move to page 2 on the pager control. Incidentally the record ID's for the child records in row 3 begin at 12 and the page size is set for 10 records to be displayed per page.

I am wondering if there is a problem with my Grid definition class. The Sample DataSet in the DAL appears to be correctly set up but I feel I have overlooked something.

Let me know how I can upload the solution.

Edit:
I did some additional checking and it seems that the grid is loading the data based on the ID of the record rather than the row number.
On Row 2 the child table ID's are 5 - 11. I have 10 records being displayed per page. Records 5-10 display on the first page. If I change the Page size to 5 then 1 record displays, the record with the ID 5. I am assuming I have missed some setting on the grid definition else this is a really bad defect.

RadToolTip OnClick Event

Can you please tell me if it's possible to fire the ToolTip when the appointment is clicked in a RadScheduler rather than have it fire every time someone mouses over an appointment?

Thanks in advance,
David

Set Bar Labels C#

See attached image. I would like to set the labels under each of the bars in my bar chart. They are currently just 1, 2, and 3. How would I could about manually setting them?

Here is my code for building that chart:

protected void makeStockChart()

{

RadChart stockChart = new RadChart();

stockChart.ChartTitle.Visible = false;

stockChart.Appearance.Border.Visible = false;

stockChart.Legend.Appearance.Visible = false;

stockChart.PlotArea.YAxis.Appearance.Visible = Telerik.Charting.Styles.ChartAxisVisibility.False;

stockChart.PlotArea.Appearance.FillStyle.MainColor = System.Drawing.Color.White;

stockChart.PlotArea.Appearance.FillStyle.SecondColor = System.Drawing.Color.White;

stockChart.PlotArea.Appearance.Border.Color = System.Drawing.Color.White;

// Create a ChartSeries and assign its name and chart type

ChartSeries chartSeries = new ChartSeries();

chartSeries.Name = "Count";

chartSeries.Type = ChartSeriesType.Bar;

// Open SQL Connection

SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);

connection.Open();

SqlCommand command = new SqlCommand("GetStockData", connection);

command.CommandType = CommandType.StoredProcedure;

SqlDataReader reader = command.ExecuteReader();

while (reader.Read())

{

// Pretty up the value

string value = string.Format("{0:d}", (reader.GetValue(1)));

// Set value and value text

ChartSeriesItem chartSeriesItem = new ChartSeriesItem(Convert.ToDouble(reader.GetValue(1)), value);

chartSeriesItem.Name = reader.GetValue(0).ToString();

chartSeries.AddItem(chartSeriesItem);

}

// Close SQL Connection

connection.Close();

// add the series to the RadChart Series collection

stockChart.Series.Add(chartSeries);

// add the RadChart to the page.

this.stockChart.Controls.Add(stockChart);

}

TimePicker ignoring custom skin

Trying to use the timepicker control, setting Skin="mySkin" and EnableEmbeddedSkins="false" , just like i do with any other telerik controls. I've got the .css file included on the page. my DatePicker styles fine, but the TimePicker does not. Looking at the source html, the timepicker html tags do not even get the custom skin. Not sure what the problem is?

any idea what's going on ? below is my .css styles. are these not the correct style classes for the control anymore?

    
            <telerik:RadTimePicker ID="RadTimePicker1" Skin="mySkin" EnableEmbeddedSkins="false" runat="server" >

how do i make controls in RadWindow trigger UpdateProgress

I'm trying to convert some AJAX modal popup extenders to RadWindows, but the LinkButtons in my RadWindows no longer trigger my UpdateProgress to appear on postback. The end result is that the user has no indication that the action is occurring and can click the buttons as many times as they choose. When I try and add the LinkButton as triggers to the UpdatePanel, I get an error that the control doesn't exist. Is there a way to associate controls in a RadWindow as UpdatePanel triggers? Here's a simplified version of the ASPX.

<asp:UpdateProgress ID="updProgress" AssociatedUpdatePanelID="updPanel" runat="server">

<ProgressTemplate>

<asp:Panel ID="progressPanel" runat="server" CssClass="IPUpdateProgress">

<table align="center">

<tr>

<td align="center" valign="middle">

<asp:Label ID="lblUpdateInProgress" runat="server" CssClass="IPLabelText" Text="Update in progress..."></asp:Label>

<asp:Image ID="imgGlobalProcessing" runat="server" ImageUrl="/Images/ajax-loader.gif" />

</td>

</tr>

</table>

</asp:Panel>

</ProgressTemplate>

</asp:UpdateProgress>

<asp:UpdatePanel runat="server" ID="updPanel" UpdateMode="Conditional" ChildrenAsTriggers="true">

<Triggers>

<asp:AsyncPostBackTrigger ControlID="lnxbtnNew" EventName="Click" />

<asp:AsyncPostBackTrigger ControlID="drxlstSearch" EventName="SelectedIndexChanged" />

<asp:AsyncPostBackTrigger ControlID="tbxSelectedValue" EventName="TextChanged" />

</Triggers>

<ContentTemplate>

<telerik:RadWindow runat="server" ID="rwNewExport" Modal="true" Title="Create New Export" Skin="IP" EnableEmbeddedSkins="false" AutoSize="true" VisibleStatusbar="false">

<ContentTemplate>

<table cellspacing="0" cellpadding="2" width="580px">

<tr>

<td colspan="3"><asp:Label ID="lbxNewValidationError" CssClass="IPValidationError" runat="server"></asp:Label></td>

</tr>

<tr>

<td>

<asp:Label ID="Label111" runat="server" CssClass="IPLabelText">Export Country</asp:Label>

</td>

<td>

<asp:DropDownList ID="drxlstNewExportCountry" runat="server" CssClass="IPDropDownList" Width="400px">

</asp:DropDownList>

</td>

<td rowspan="2">

<asp:LinkButton ID="lnxbtnSaveNew" runat="server" Style="padding-right: 4px; padding-left: 4px; padding-bottom: 4px; padding-top: 4px" CssClass="IPLinkButton">Go</asp:LinkButton>

</td>

</tr>

<tr>

<td>

<asp:Label ID="Label112" runat="server" CssClass="IPLabelText">Import Country</asp:Label>

</td>

<td>

<asp:DropDownList ID="drxlstNewImportCountry" runat="server" CssClass="IPDropDownList" Width="400px">

</asp:DropDownList>

</td>

</tr>

<tr>

<td colspan="3"> </td>

</tr>

<tr runat="server" id="rowTemplateHeader" class="IPGridHeader">

<td colspan="3">

<asp:Label ID="Label113" runat="server">Create New Export From Template</asp:Label>

<td>

<asp:LinkButton ID="lnxbtnSaveFromTemplate" runat="server" Style="padding-right: 4px; padding-left: 4px; padding-bottom: 4px; padding-top: 4px" CssClass="IPLinkButton">Go</asp:LinkButton>

</td>

</tr>

</table>

Change Image in Radgrid Column

Hello All,

I have a RadGrid with EditCommand Column as the first column in the grid. I have a edit image set for all the rows in that column. I did this by putting the editImageURL property.
Now. My question is, Is there a way to change the Image of that column dynamically based on the value of other column in the grid?

I want to change the first column's image of a grid based on other column value. Can i do it in the aspx page or Is it best way to do it from code behind?

If I have to do it from Code behind, How can I access the image folder( which has all the images I am using in the project) in my project from code behind. If it is aspx page we can set the property like editImageUrl .

Sys.WebForms.PageRequestManagerServerErrorException

On one of my pages I'm getting this error when I click on the calender control on my page...

Error: [Exception... "'Sys.WebForms.PageRequestManagerServerErrorException: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500' when calling method: [nsIDOMEventListener::handleEvent]" nsresult: "0x8057001c (NS_ERROR_XPC_JS_THREW_JS_OBJECT)" location: "<unknown>" data: no]

It doesn't give the error when I run from VS 2008 but when I promote to any other server I get the error. It only happens when I click on the calender control.

I searched these forums (and others) and have tried all of the suggestions (there are no response.writes, response.transfers, or anything like that).
