Asp.Net Gridivew PageIndexchanging problem

Question

Hi friends I am entering children details like sr no child name and age in a gridview. There is a button called ADD NEW in a footer. When I click on the button the new empty row gets added. I have set the allowpaging property to true and called the function on pageindexchanging. But when I go on second page and again come back on first all the data gets vanishes and empty row remains. Here I have set the page size to 5. Any help would be appreciated Thanks Vijay

How you binding the records on Page Load? If yes then use if(!IsPostBack) condition.

Suthish Nair · Answer

Before paging you need to store the old values after paging done rebind the new data. Or use UpdatePanel might works. Or do not allow user to do paging during edit mode. http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.pageindexchanging.aspx

I dont think your pageindexchanging function is wrong. Try during debug mode find between add new button click event and databing check if your grid data is null or not.

Hi Is your problem solved? send me the code if not.

Hi Vijay I think you are not binding the gridview in PageIndexchanging event. try this protected void GridView1_PageIndexChanging( object sender GridViewPageEventArgs e) { GridView1.PageIndex = e.NewPageIndex; BindGrid(); }
