Question
ASP.NET Gridview user input textbox problems
Hi All,
I am developing an shopping list Application with the items displayed in a grid view. There are two columns at the end which are template fields, one contains a textbox calles txtQuanity and the other contains a button called btnAdd.
Onclick i need to be able to add the details of the row and the quantity from the text box to a table in the database. However the gridview columns have filters which need the postback event to rebind the GV but when this happens the value entered in the textbox is lost so the quantity is "". how can i save the value before the page is reloaded???

I have to rebind the gridview because i have filter dropdowns which are linked columns in the gridview. The columns are populated with a distinct query based on the populate gridview query so to select a value from the dropdown fllter it needs to rebuild the gridview and the dropdown lists which is why it needs a postback to trigger the rowbounds event in the gridview. unless there is a way to do this without a postback?

Check you Page_Load event handler.
You need to have a IsPostBack block to make sure that the GridView will not be rebound upon postbacks.
