DropDownList and Ajax

Hello Everyone,

having very weird bug ,

page consists of following controls
- DataList to show records
- object data source
- PagedDataSource for paging of datalist (code behind)
- DropDownList for selecting paging size with values 3, 5(default), 10, 15

All above controls are kept in UpdatePanel.

Working of page

On DropDownList1_SelectedIndexChanged event I am setting PagedDataSource1.PageSize to DropDownList1.SelectedValue, then bind the DataList Control to show the records.

This works fine for the first run of the page, I get 5 records per page. If I change paging size to some other values it works, but when I change it to same default value i.e. 5 the DropDownList1.SelectedValue returns blank. Similar thing happens for any value which is set to default in DropDownList.

Thanks in Advance

Hi Niyin,

To troubleshoot this issue, we really need the source code to reproduce the problem, so that we can investigate the issue in house. It is not necessary that you send out the complete source of your project. We just need a simplest sample to reproduce the problem. You can remove any confidential information or business logic from it.
