Questions on UI for ASP.NET AJAX Forum

Hi,

I am using Ribbon UI in my master page. The content pages are within ajax update panel. I prompt my users to save the form details, when they navigate away from a page.

Scenario:
If a user does not save a form and tries to navigate away by clicking on a button in the ribbon UI(redirects to some other page), a prompt appears with Ok and Cancel. If the user clicks OK, he navigates to the link. If he clicks on cancel, the page redirection will not happen.

Error:

When the user clicks cancel, An "unspecified error" pops up. This happens only if the user tries to navigate by clicking a button in ribbon UI

function __doPostBack(eventTarget, eventArgument) {

if (!theForm.onsubmit || (theForm.onsubmit() != false)) {

theForm.__EVENTTARGET.value = eventTarget;

theForm.__EVENTARGUMENT.value = eventArgument;

theForm.submit();--------->Error here

}

first file always selected

hi, sorry about the multiple posts on this, the forum kept saying there was an error.

I am having a problem where the client selected item is always the same. I'm just using the javascript from the detecting selected file example, the only difference is that I have a custom FileBrowserContentProvider for sharepoint. When I click a file in the grid, the event args passed to the selected item event handler are always for the first item instead of the one I selected. I also tried using sender.get_selectedItem() instead, but that also always returns the first file item, even though the highlighted item is different.

Has anyone hit this problem before? Any idea what might be causing this?

Declarative aggregate for a GridTemplateColumn

Using the following template column code I can define an aggregate for the column, but nothing is displayed. Does the declarative aggregate work now for a GridTemplateColumn, and if so, what can I do to display the result?

<telerik:GridTemplateColumn UniqueName="IsInvitationAccepted"
    DataField="IsInvitationAccepted"
    HeaderText="Confirmed?"
    HeaderTooltip="Has this speaker confirmed their acceptance?"
    HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center"
    FooterStyle-HorizontalAlign="Center"
    Aggregate="Sum" FooterAggregateFormatString="Confirmed: {0:F0}"
    >
    <ItemTemplate>
        <asp:Label ID="LabelInvitationAccepted" runat="server"
            Text='<%# Convert.ToInt32(Eval("IsInvitationAccepted"))==1?"Yes":"No" %>' />
    </ItemTemplate>
</telerik:GridTemplateColumn>

[Solved] chart text is not printing transparency

The chart looks good in the viewer but none of the labels print out with a transparent background. Every label has a white background which makes the chart look like everything overlaps with white boxes and cuts out a section of a bar next to it. I have set transparency in the series item label appearance and so on. It's a 3 series chart with 25 points so they are narrow bars. So how do I get the print out to match the screen? Also its doing this on all the printers around here.

[Solved] Have to click twice on ExpandCollapse button

This is odd. I just upgraded my web project from the old RadControls for ASP.NET to the latest ASP.NET AJAX controls. I have several hierarchy grids that use the HideExpandColumnRecursive method. These worked fine under the old controls.

With the new controls, the ExpandCollapse button hides as it should when there are no child records in the 2nd level.

But, if there are child records, then the ExpandCollapse button is visible. When I click on it,
The column containing the buttons narrows, the button icon narrows, but nothing else happens.
On a second click the child grid opens as expented, and the button column remains narrowed.
On subsequent button clicks, the child grid opens and closes ok.

If I refresh the page, then once again two clicks are needed to expand the row.

Has anyone else run into this? Thanks.

Dan

Grid doesn't display data, just "System.Data.DataRowView"

I have a grid that I am using to display search results in. This is my first project using a RadGrid. I'm using VB.Net in Visual Studio 2008.

I created the 3 columns ahead of time and then when the search is run I fill a DataSet with the SQL query results, set the DataSet as the "DataSource" and then call "Rebind" on the grid.

The grid properly redraws and shows me that there were 3 rows of results returned, but each cell of the table simply shows "System.Data.DataRowView" instead of the actual values.

Is there some property I'm missing somewhere that is causing the table to not show me the actual data in my DataSet?
