I am using the Tabstrip with pageviews, I am following the example Load on Demand RadPageview...
In my case I am loading child tabs with the associated page view, then dynamically adding controls to the page view.
When the page first loads I can click on all the child tabs and see my content rendered.
So here is the problem, I can click on child page 1 it renders.. then I click on other child tabs (child page 2) it renders. When I go back and click on child page 1, my content is gone.
I know this must be a view state issue...
So any help would be appreciated.
Thanks
Julie

Please check if you are setting ID's to the USerControls that you load, i.e.
| protected void RadMultiPage1_PageViewCreated(object sender, RadMultiPageEventArgs e) |
| { |
| string userControlName = e.PageView.ID + "CS.ascx"; |
| Control userControl = Page.LoadControl(userControlName); |
| userControl.ID = e.PageView.ID + "_userControl"; |
| e.PageView.Controls.Add(userControl); |
| } |
If this is not the case, I think it will be best if you can open a support ticket and send us a simple running project (incl. CSS, images, DB backup and so on) demonstrating the problems. In that way we can reproduce and pinpoint the problems you're facing on our side, understand the logic of your application and provide a solution.

With a twist to this model, I am dynamically creating a table with controls in
RadMultiPage1_ PageViewCreated
{
Table tbl new Table();
tbl.ID = e.PageView.ID + "_table";
TableRow tblrow new tblRow();
TableCell tblcell new tblcell();
tblcell.text = "Some Text";
tblrow.Controls.Add(tblcell);
tbl.AddControls(tblrow);
e.PageView.Controls.Add(tbl);
}
Does the load on demand feature on work with usercontrols?
What is the best approach for this scenario?

I'm not sure that we clearly understand your question. Could you please provide more details? In addition, please take a look at our Load on Demand RadPageView example that shows the approach.

I figured out the problem....
With the application I am building I load content as described below....
I dynamically add tabs and child tabs, the child tab_click pulls the information below from a data table.
Then I construct the Table (relying on the rowcount of the datatable) as described below adding a dynamic number of rows.
It renders fine the first time but as I click on the other parent tabs and child tabs then go back to a tab previously rendered, it does not reload the pageview. If I add a static counter, it works fine no problem viewing the previously defined pageview. (see example below that does work....
/// This one does not work
RadMultiPage1_ PageViewCreated
{
DataTable newdata = DataTable
{
Sql code to pulls the data....
}
if( newdata.Rows.Count > 0 ) \
{
Table tbl new Table();
tbl.ID = e.PageView.ID + "_table";
for(int i=0; newdata.Rows.Count > i ; i++)
{
//This count will never be consistant as the data is dynamic... in some cases it will datatable will return 5 rows
// In others the datatable will return 30 rows....
TableRow tblrow new tblRow();
TableCell tblcell new tblcell();
tblcell.text = "Some Text";
tblrow.Controls.Add(tblcell);
tbl.AddControls(tblrow);
}
e.PageView.Controls.Add(tbl);
}
}
/// This one works
RadMultiPage1_ PageViewCreated
{
DataTable newdata = DataTable
{
Sql code to pulls the data....
}
if( newdata.Rows.Count > 0 ) \
{
Table tbl new Table();
tbl.ID = e.PageView.ID + "_table";
int MaxCnt = 10;
for(int i=0; MaxCnt > i ; i++)
{
TableRow tblrow new tblRow();
TableCell tblcell new tblcell();
tblcell.text = "Some Text";
tblrow.Controls.Add(tblcell);
tbl.AddControls(tblrow);
}
e.PageView.Controls.Add(tbl);
}
}
If you need a working example, I can provide that in the next few days..... but it is easy to duplicate this issue...
