Based on my test using the latest build of WebScheduler 3 and WebUI Framework 3, build 4 and build 752 respectively, I could not replicae the issue in your video using the Client_GetCellElements.aspx WebScheduler provided sample.

Have you already apply the latest build of WebScheduler and WebUI Framework in your project?

I do not see any mistake with the method to add a single row you provided.

You could try our live chat available in this link. However, currently as stated in the page our live chat is only availble from 8AM - 5PM (GMT+7) weekdays.

Support for US timezone is already planned and is scheduled for next week.

A quick search in google with the error message you encounter resulted in this article

The article solution for the issue you encounter is setting up mapping between logins using sp_addlinkedsrvlogin

Attached is a simple sample that I used in order to replicate the scanrio you are facing. In my environment the sample will run without any issue, no javascript error occured.

The custom control which inherit WebTab is in the Class1.cs file and the page which use the custom control is CustomTab.aspx

There is some limitation in inheriting our control, such as the WebUI designer will not be available for the custom control.

The null parameter is caused because the insert parameter in the IS DataSource does not match the field which already bound in the EventBinding WebScheduler property.

Here is the EventBinding property in your WebScheduler attached project:

<EventsBinding AllDayEventField="AllDayEvent" CategoryIDField="CategoryID" DescriptionField="Description"
EndTimeField="EndTime" EventIDField="ID" LocationField="Location" ModeField="Mode"
ReminderTimeSpanField="Reminder" ResourceIDField="ResourceID" StartTimeField="StartTime"
SubjectField="Subject" />

The correct insert parameter in the IS DataSource table Events:

<InsertParameters>
<asp:Parameter Name="ID" Type="Int32" />
<asp:Parameter Name="CategoryID" Type="String" />
<asp:Parameter Name="ResourceID" Type="Int32" />
<asp:Parameter Name="Mode" Type="Int32" />
<asp:Parameter Name="Subject" Type="String" />
<asp:Parameter Name="Description" Type="String" />
<asp:Parameter Name="Location" Type="String" />
<asp:Parameter Name="AllDayEvent" Type="Boolean" />
<asp:Parameter Name="StartTime" Type="DateTime" />
<asp:Parameter Name="EndTime" Type="DateTime" />
<asp:Parameter Name="ReminderTimeSpan" Type="Int32" />
</InsertParameters>

You could analyze the provided WebGrid sample, BindtoHierchicalCustomObject.aspx, for the custom object hierarchical data in ISDataSource and WebGrid. Regarding the custom paging, the article titled "Walkthrough: Implementing Custom Paging using ISDataSource" in the WebGrid documentation already detailed Custom Paging and ISDataSource.

In both case above, you will only need to use IntersoftDataSource.

CustomFiltering and CustomSorting will be handled during server side WebGrid event handler as explained in these article "Walkthrough: Applying custom filtering in WebGrid" and "Walkthrough: Applying custom sorting in WebGrid" in the WebGrid documentation.

Currently it is not possible to get the reference to LINQ object from WebCombo.

If you need to lookup another column which is not defined in the Text or Value property you could try using the Rows property of WebCombo, however this will return a DataRow object.

Attached is a simple demonstration of such technique.

Unfortunately, we do not have a system with the VS 2010 RC. We do however have a system with VS 2010 RTM.

Using the provided WebAqua sample on VS 2010 RTM in order to test the issue, I could not replicate the issue you mentioned. Have you confirm that you already use the latest WebAqua and WebUI Silverlight Framework, WebAqua 2 build 221 and WebUI Silverlight Framework 1 build 104

As fas as I know no such issue has been reported before and without being able to replicate the issue in our environment we could not know for sure the cause of such issue. Please confirm that you are already using the latest build of our control, which is WebGrid 7 build 403 and WebUI Framework 3 bild 752.

Does the simple sample WebGrid already reflect the setting your are using? Did you use filter? How many data is in the grid? What kind of paging did you use?

You could also share how to replicate the issue in the production environment so we could try to replicate the issue in our environment.


Sure, we will send you the build after a fix has been develop. I have add a note in the bug fix regarding your request.

In the mean time, based on further testing. Using the nightly build, please try this workaround to achieve your scenario:

During postback button click event handler after invoking PerformBatchUpdate, execute a RefreshAll function in the client side. Here is the snippet:

protected void Button1_Click(object sender, EventArgs e)
{
_grid.PerformBatchUpdate(true,true);
Page.ClientScript.RegisterStartupScript(this.GetType(), "RefreshGrid", "<script>RefreshGrid()</script>");
}
function RefreshGrid()
{
var grid = ISGetObject("WebGrid1");
grid.RefreshAll();
}
