Hi All,
I have created a table called tblState in access with 2 columns: id and state and am populating a dropdownlist with state.
I am in need of code to delete a selected value of dropdownlist from database in asp.net2.0 using c#.
Can anybody help me please.
Thanks
Wajid

On postback, you can tell what your selected item is, what you need to be able to do, is turn that into an id you can use to delete the right record in the database. You do that when you populate the list, by using the unique ids as the data value for the list item ( the value that is not displayed )

Hi Guy
do this way, put ur dropdwon list with Updatepanel,When you desired delete a item from the dropdownlist,first get the ID when u selectedValue, after send that ID to ur Database acces code and delete,after select all from the database and bind again to DropdownList,if you put in the updatepanel, doesn't take much more time for this operation.

The OP never mentioned anything about needing asynchronous processing. Why are you suggesting using an UpdatePanel?

It takes just as much time as without an update panel. UpdatePanel just gives the user the perception of a faster operation because of the out-of-band processing and no page refresh.

But, AJAX is the new magic bullet, didn't you get the memo ?

Hi Guy
I think we want do fast work for that, becuase if when he select a item from the dropdownlist and process delete command, he wihs's delete from the database, so we must bind data again to dropdownlist, so i thought we reduce the time for the operation since, suggest AJAX update panel.
Just use ad tell me, how about applciation perfomance this operation

The time it takes to perform the operation will not be reduced by using an UpdatePanel!!

Hi Guy
i told not loading and getting and binding operation time man, i told page refresh and data show time. means, if u use update panel, postback time is very very less.

With only 2.5 years you obviously don't have "excellent experience in programming" or "excellent knowledge...with all other MS related languages and databases"

Are you certain that DropDownList1.SelectedValue is correct?
Since ID appears to be a unique key in the table structure use that for the value. This eliminates the need to pass strings around and do string comparisons. It also guards against deleting multiple rows with duplicate state values.
DropDownList1.DataValueField = "ID";
int id = Convert.ToInt32(DropDownList1.SelectedValue);
string strDelete = "delete state from tblState where ID=" + id + ";

If you want this on javascript try the below on the onclick event of the button, (OnClientClick, if it is a Server Side button)
func(document.getElementById('MY_TEXTBOX').value)
If you want the above in ASP.NET, double click button, it will take you to the code behind, where you can try the below code in the Button Click event,
func(MY_TEXTBOX.Text);
Here MY_TEXTBOX is the ID of the textbox you mentioned

document.getElementById returns an object. How will this work in your example?

It should be
func(document.getElementById('MY_TEXTBOX').value);
Thanks Marks for pointing out.
