when iam using a textbox control when user enter the any part of column or any filed in the text box it should come like popup in the textbox from database
Can you clearer? It's really difficult to understand what you are trying to ask right now.
like: Where from column came into question when talking of textbox? What do you mean by, field in textbox should come like popup in textbox from database?
Elaborate a little and tell where DB comes into picture and what exactly needs to be displayed in the popup?
iam having textbox in asp.net when user enter any value either branchname oraddress or emailid or phone no or mobileno the solution should comes like autocomplete extender . popup should come in textbox text
using asp.net with c#. give me a example which helps me.
It's not question of the .net code, it's a question of how the data is structured and queried. Are you trying to use any complex joins? Do you have covering indexes? Do you really need to retrieve all 100000 at once? This seems extremely excessive for a mobile application.
If you have a Next, Previous button you should be having PageIndexChange event for that GridView. In that event handler you need to "rebind" the data with filter condion that has already been selected. So you need to Save the select query too (using any session management technique ie. ViewState, Hidden field, session variable per your requirement.
