Why do you do your insert in the page load ? What if someone refreshes the page ? Why use the Form and not txtmovieName.Text ?

Yeah, I missed a line, sorry.

I'm not sure what you're asking. You have code for an insert, why do you have trouble with inserting some values into a different table ?

hi i did try the same code but it like not able to work. Now the problem is in the dropdownlist of actor when the actor click add then the selected value need to be in the listbox, if the value is "Others" then they user will need to enter the name n when they click add new the name will go to the listbox now i have problem in adding the value into the listbox. please advice on how to add the value into the listbox when the user click add n add new. Thanks

Your listbox should be populated from a database call, just make a DB call to get the right list of values, set that return value to be the datasource of the control, and call databind

hi. thanks. The requirement that i need to do is to get the value from the dropdownlist n textbox to display in the lsitbox n when the user click the submit button it will add teh value from the lsitbox into the actor n director table in access database. thanks

Christian Graus18-Jun-07 15:56

You need to get the values that are in the dropdownlist, or you need to use the value in the dropdownlistto work out how to populate the listbox ? Your dropdownlist should give you the info you need to request the correct data for the listbox, that's kind of where I was headed.

the dropdown list is already [opulated with values. when the user select the item in the dropdownlist n click the add button next to the dropdownlist. the selecteditem need to be disply in the listbox. thankss

Christian Graus18-Jun-07 16:06

Oh - you want to add one item to the listbox ? This will probably be done in javascript, just handle the button click, grab the selected text from the drop down and add it to the collection of items in the list box. THere's tons of examples on the web for that sort of stuff.

Well, SQL gets the data out, then you bind it to your grid, in the manner I described.
