Solution 1

Hi,

Try this:

C#

string selectedOptionValue = city_id.Items[city_id.SelectedIndex].Value;
string selectedOptionText = city_id.Items[city_id.SelectedIndex].Text;

Hope this helps.

protected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
{string selectedOptionValue = city_id.Items[city_id.SelectedIndex].Value;
}
when i do this, i get this error
"The name city-_id does not exist in the current context,

You need to change city_id into the ID of your select tag. Also, you should add runat="server" to the select tag if it's not yet added.

i do it
<select size="1" name="city" ID="city_id" runat="server">
<option selected="selected" value="">please select your city</option>
</select>
but not work :(

Can you show all the code in your body tag?

SadeqHatami 17-Aug-13 5:31am

i try this but my body tage is big and can't show this place...

i use CreateUserWizard1 and in <asp:CreateUserWizardStep> i use <select size="1" name="city" id="city_id" runat="server">
<option selected="selected" value="">select your city</option>
</select>
and in c# code:
protected void CreateUserWizard1_CreatedUser(object sender, EventArgs e)
{ string selectedOptionValue = ostan_id.Items[ostan_id.SelectedIndex].Value;
}
and get this error:
The name city_id does not exist in the current context,

In your code, you use ostan_id but if you use ostan_id, then you should change the id of the select tag into ostan_id

i change it but i get same error

Thomas Daniels 17-Aug-13 6:10am

I get no error. I'm sorry, but I've no idea what's wrong.
