Posted Date: 26 May 2005      Posted By:: Ashok     Member Level: Gold  Member Rank: 0     Points: 2   Responses: 5

i have a senario where i need to load the dropdownlist with the data from the datasource . When the dropdownlist is loaded i need to select the selected value to a user previously selected value. For example
i have a dropdownlist has all states such as NJ,NY,PA . But, in our database the user already have selected NY from this selection before. Now when i load this dropdownlist again i want to have this 'NY' selected as the first value in the dropdownlist. Can anyone please help me ?????/

Hi,

Before calling the databind function. get the value selected and store it in some temp variable. After the databind function. Run a loop which will traverse through the entire items check for value and make ur selection.

With regards,

i tried it with
DropDownList1.SelectedIndex = Convert.ToString(DropDownList1.Items.FindByText("NY").Value)


i am getting an error

Input string was not in a correct format.


i think it is becasue i am assigning "NY" to the integer value index.


Can you advise me on it
