Here is what am trying to accomplish...I want to have a DropDownList that is populated by a field from a table. Then once a user selects one of the enteries, he/she then enters a value for that selection in a textbox, then clicks enter or add....now upon doing this, I want to have a GridView that tabulates all the entries the user adds, and keep a total of all entries as the bottomline in the GridView. I can't seem to wrap my head around how to get it done.Does anyone know how I can get this done, or are there examples out there that my searches have missed cause I haven't really seen any examples I could look at. I would think this should be a common solution that is used all over

I have a modalpopup extender that is brought up if the user presses a button. This is fine and the user can enter the data. There are a number of textboxes and dropdownlists. However, I have a gridview which I want to bring up modalpopupextender so the user can edit an entery. How can I set the data to the controls? A dynamicpopulate extender will repopulate the modalpopupextender with all the data. It doesn't make sense for me. Is there anyway I can populate the data with c#? Also can I assign two buttons to call the modalpopupextender?

what i am doing is that, I First Filled A Dataset With Required Value Then I loped This Dataset Row For Value On Which I Have To Get Data From Another Database Again I Stored new data in another dataset and After Looping, I Merged It With Previous One.
I have several stored procedures in my database, some of them have params, some have no params. I tried to fill a business object by calling the stored procedures, but failed so far. How could I do that dynamically? Later, I want to use this object as a datasource for a report...but thats the next step. The important facts are:
different stored procs return different amount of columns stored procs can have params, but its not required
I have a database where a user inputs data to multiple databound drop down listboxes. That's saved to my aspnet database. Then when the page loads again, I want to select the ddls items that the user selected as stored in the database to these databound ddls. But it doesn't work, because on pageload, they haven't been databound yet.
What's the best way to do this? Do I need to run a SELECT statement for each and every ddl on it's databound event?
