Grand Total on top of the stacked bar chart

Hi

I want to display the grand total on top of the last series. When i do the DefaultLabelValue for the last chart series, it is overriding the last series label value. Please guide me to achieve the grand total in the stacked bar. Please see the attached image.

if (cs.Index == chart.Series.Count-1)

{

cs.DefaultLabelValue = "#STSUM";

cs.Appearance.LabelAppearance.Position.AlignedPosition = Telerik.Charting.Styles.AlignedPositions.Top;

cs.Appearance.LabelAppearance.LabelLocation = Telerik.Charting.Styles.StyleSeriesItemLabel.ItemLabelLocation.Auto;

}

Anyone guide me how the calculation is happening for the

cs.DefaultLabelValue = "#STSUM"; So that i could add one more series with all the values as 1 and substracting 1 from the total.



Regards

Arima

Refresh data on lower levels of a RadGrid

Hello, Telerik Team,
I have a question about your RadGrid control.

I have a Hierarchical RadGrid with two levels, the markup of the grid looks like this:

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="true" AllowCustomPaging="true"

AllowMultiRowSelection="true">

<MasterTableView DataKeyNames="ID" ClientDataKeyNames="ID" InsertItemPageIndexAction="ShowItemOnCurrentPage">

<Columns>

<telerik:GridButtonColumn ButtonType="ImageButton" ImageUrl="~/Images/Icons/Edit.png"

CommandName="Edit" Text="Edit"

UniqueName="EditColumn">

</telerik:GridButtonColumn>

<telerik:GridButtonColumn ButtonType="ImageButton" ImageUrl="~/Images/Icons/Delete.png"

CommandName="DeleteShift" ConfirmText="Do you want to delete this Shift?" ConfirmDialogHeight="150"

ConfirmTitle="Confirmation" ConfirmDialogType="RadWindow"

Text="Delete" UniqueName="DeleteColumn">

</telerik:GridButtonColumn>

<telerik:GridButtonColumn ButtonType="ImageButton" ImageUrl="~/Images/Icons/AddRecord.png"

CommandName="AddJob" Text="Add Job"

UniqueName="AddJob">

</telerik:GridButtonColumn>

<telerik:GridButtonColumn ButtonType="ImageButton" ImageUrl="~/Images/Icons/ExportCSV.png"

CommandName="ExportJobsCSV" Text="Export Jobs"

UniqueName="ExportJobsCSV">

</MasterTableView>

<ClientSettings>

<ClientEvents OnCommand="gridCommand" />

<Selecting AllowRowSelect="True" UseClientSelectColumnOnly="true" />

</ClientSettings>

</telerik:RadGrid>

The refreshGrid Javascript function looks like this:

function refreshGrid(sender) {

$find("<%= RadGrid1.ClientID %>").get_masterTableView().rebind();

showScrollBars();

}

I have a RadWindow where another page is loaded where I can add/delete/modify columns and I have a "sunny day" scenario when the columns in the outer level are changed: the grid is rebinded and the new columns appear nicely. However, when I modify/delete/add columns in the inner levels the grid is rebinded, but the column set in the inner levels is not refreshed. I've debugged the server-side code and everything is fine there, but on the client side I have the old column setup. Is there a solution to my problem, or should I wait for a new version of Telerik?

Note: I've done a temporary hack to hide this anomality from the users where the refreshGrid function only rebinds if the column modification/deletion/insertion happened in the outer layer. Elseway the page is reloaded. I know this is an ugly hack, but I don't see any alternatives.

I appreciate any help.
Sincerely Yours,
Lajos Arpad.

Control bind order changed with RadAjaxManager?

I have a fairly simple page that contains a DropDownList control and a DetailsView control in a master/details type setup.

The DetailsView displays the details of the record selected in the DropDownList.

This form works perfectly without RadAjaxManager.

However, as soon as I hook up the RadAjaxManager I get errors in the code.

Troubleshooting the issue I was able to determine that the DetailsView.DataBound event is being triggered BEFORE the DropDownList.DataBound event. Code in the DetailsView.DataBound event populates a control within the DetailsView with data associated with the currently selected item in the DropDownList. But an error occurs because there is no DropDownList.SelectedValue because the DropDownList control hasn't been databound yet.

As I said, this does not occur when RadAjaxManager is not on the page.

What do I need to set in RadAjaxManager to make sure that the controls get bound in the correct order? (top-down)

Note I've hooked up event handlers for DetailsView.ModeChanged and DetailsView.DataBound. Also note I've hooked up the DropDownList.PreRender event as well with the following code:

    
            CType(sender, DropDownList).Attributes.Add("onChange", "window.focus();")

I need to have this code because the user may use his mouse wheel to scroll the page, but if the DropDownList is selected it will scroll that instead and reload the DetailsView.

Client-side paging events?

Hi,

Are there any events on the client side which fire when a new page is requested from the grid for which I can write javascript code to handle?

The reason that I ask is that I have a grid with client-side binding and caching enabled. This works pretty much as I would expect except that when you go to a page which is cached the RadAjaxLoadingPanel isn't shown and I would really like to show it and hide it again for the cached pages as it is great indicator as to whether something is going on.

ExportToExcel Causing Object not set to an Instance of an Object

I have successfully tested this feature on my dev and live server on multiple browsers on my machine. However the user is receiving the attached screen. The user is using Internet Explorer, although not sure which version at this time.

I used an ImageButton for the export button.

protected void exportToExcel_Click(object sender, ImageClickEventArgs e) {

radGridVesselUtil.ExportSettings.IgnorePaging = true;

radGridVesselUtil.ExportSettings.OpenInNewWindow = true;

radGridVesselUtil.ExportSettings.ExportOnlyData = true;

radGridVesselUtil.ExportSettings.FileName = "vessel_util_" + DateTime.Now.ToShortDateString();

radGridVesselUtil.MasterTableView.ExportToExcel();

}

Put two columns under a header.

I have a radgrid where I want to put two columns under a header. I am attaching a screenshot to this thread to show you what I want. You will see the column "Open Items by Age" is further divided as "Prior" and "Current" columns. Is this possible to do in a radgrid and still maintain the sort for the "Prior" and "Current" columns. I am attaching code to help you see my grid.
