Questions on UI for ASP.NET AJAX Forum

Hi guys,

No idea what's happening here. Been trying to fix for a week.

It was working great last week but now when a new task is clicked, the ajax loading image just keeps spinning. While it's spinning, if I refresh the page straight away, I can see that the record has gone into the database and it shows up in the chart.

I read on a couple of other posts about this scenario, but could not find a fix.

Cheers,

Jon

How can we show page number as 'Page 'n' of Total number of pages' in PDF reports

Currently while exporting report to PDF, only current page number is displayed at the bottom of each pages. Instead of this, we would like to show page number in 'n' of Total number of pages' format.

Any suggestion for this?

Thanks.

Exposgin Column Collection in a User Control for RadGrid

I was trying to create a User Control for standardizing the Grid Control across all the forms. Surely all the forms will have different columns but the layout is the same across except for few properties here and there. How do I expose the Column Collection?

My Code would be:

<telerik:RadGrid ID="grid" runat="server" AllowCustomPaging="false" AllowPaging="False" AllowSorting="False" AutoGenerateColumns="False" CellPadding="0" CellSpacing="0" CssClass="gridCandidate" Height="100%" Width="100%">

<ClientSettings EnableAlternatingItems="false" EnableRowHoverStyle="true">

<Scrolling AllowScroll="true" UseStaticHeaders="true" />

<Selecting AllowRowSelect="True" />

<ClientEvents OnRowDataBound="function() {}" OnCommand="function(){}" />

</ClientSettings>

<MasterTableView AllowFilteringByColumn="False" AllowNaturalSort="false" ClientDataKeyNames="ID" DataKeyNames="ID" EnableColumnsViewState="False" EnableViewState="False" HierarchyLoadMode="Client"

NoMasterRecordsText="<div class='noRec'>No records to display.</div>" TableLayout="Auto">

<Columns></Columns>

<HeaderStyle Height="0px" />

<PagerStyle Visible="False" />

</MasterTableView>

</telerik:RadGrid>

[MergableProperty(false), DefaultValue((string)null),

PersistenceMode(PersistenceMode.InnerProperty)]

public GridColumnCollection Columns

{

get

{

return grid.Columns;

}

set

{

foreach (GridColumn column in value)

{

grid.MasterTableView.Columns.Add(column);

}

//grid.MasterTableView.Columns.Add()

}

Any idea how to expose the Columns property?

Can MS-Word document open via C# code in RADEditor?

I just wanted to open document in RADEditor through C# code, instead of navigating File->Open link in RADEditor. If this is possible, I'll display the document link in my web application to open the respective document in RADEditor.So that, can edit the word document in RADEditor and save it on the server which is hosted. Let me know the case is possible.

RadTextBox and RadDropDownList overlap when placed next to each other in table cell

I have a requirement to dynamically build a table on server side and fill it with either textbox(for entering strings) or textbox with a small drop down next to it to enter numbers and unit of measure. My problem is that if I add both text and drop down to the same cell drop down overlaps text box for few pixels and is not aligned with other controls in rows above.normal text box size is 200(from CSS) and short is 150(from CSS). List box width is set to 50, so I expect controls to be aligned, but they are not. Screen shot attached. How this can be fixed?

Here is my code :

CSS:

.myLabelCss {
            color: Red !important;
            width: 20px !important;
        }

        .myLabelCssDD {
            color: Red !important;
            width: 10px !important;
        }

        .CustomClass {
            width: 200px !important;
        }

        .CustomClass .riSingle .riTextBox {
                width: 200px !important;
            }

            .CustomClassShort{
            width: 150px !important;
        }

Table declaration

<asp:Table ID="tblParms" runat="server" Font-Names="Arial" ForeColor="Black" CellSpacing="10" BorderColor="Black" Width="100%"
EnableViewState="False" BorderStyle="None" meta:resourcekey="tblParmsResource1"> </asp:Table>

VB code:
