Disappearing Gridview

[billybob206]

Hello:

I'm developing a search page that will display the results in a gridview. The codebehind (in VB.NET) uses a SQL command to fill the gridview.

The gridview does have paging and sorting enabled. Once the search button is clicked the initial results are displayed, if the user clicks on a sorted column or wants to advance a page the gridview disappears. Enable Sorting And Paging Callbacks is set to True. Enable ViewState is also set to True.

Thanks in advance for the help.

You have to bind the GridView to the data source after paging or sorting.

Is that done in the GridViewSortEventHandler?

I typically re-bind my GridView controls in the Page PreRender event but you don't have to...you should sort your data source based on the sort criteria that the user selected/clicked on and then re-bind your GridView to the DataSource.

So, yes, do it in the Sort event handling code.

Sorry. The solution was obvious (in my view). Just go into the Events property section of the gridview and then select the function (or procedure) that fills the gridview in the PageIndexChanged and Sorted fields.
