VS 2010 - Dropdownlist Getting Index
Feb 13, 2013I've made a small site which purpose is to allow people to add members to their clan. The page has a dropdown list with the names of all available clans.
The name of the clans and the clan password come from a text file which is read when loading the page (but not when there's a page postback) and adds the clans to the dropdownlist.
The clan name and clan password are also read into an array for later use.
When the user selects an item in the dropdownlist I want to get the index so I know which clan name to use and which password.
I tried getting the index by using the indexchanged event and also just the click event of a button but somehow this doesn't seem to be working properly.
When the user filled in all fields and hits the submit button I want to check if the password is correct and want to know the clanname. I'm trying to do this by using the array's with that data and setting the item of the array equal to the index of the selected item in the dropdownlist.
But when I press the button I keep getting a wrong password error even though it's correct. If I remove the password check and submit it then the form should create or append to a text file with the name of the clan. But when submitted the text files is .txt instead of clanname.txt.
Tried setting the dropdown to autopost back or without and get the same result.
My code is the following:
reading the data into the array + adding the clannames to the dropdownlist
vb Code:
Dim data() As String Dim clanname(50) As String
Dim clanpass(50) As String Protected Sub Page_Load(sender As Object, e As System.EventArgs)
Handles Me.Load
Dim fileName As String = "C:/ClientSites/data/clans.txt"
[Code] ....
The submit button code
vb Code:
Protected Sub btnSubmit_Click(sender As Object, e As System.EventArgs) Handles btnSubmit.Click
naam = txtMemberName.Text.ToString gamertag = txtGamerTag.Text.ToString
platform = txtPlatform.Text.ToString index = DropDownList1.SelectedIndex
paswoord = clanpass(index)
[Code] ....
In short I load in data from a file into two arrays, clanpass and clanname. Populate the dropdown with the clannames. Then upon submitting I want to check the password against the password for the selected item by using it's index. I also want the name to write it to the correct text file.

VS 2008 DropDownList - Selected Index Changed
Jul 12, 2012I am using SelectedIndexChanged in the DropDowList and it works fine and populates a GridView based upon a site selection.

VS 2008 / Unable To Get Selected-index Of DropDownList?
Jan 26, 2012I am populating a DropDownList from a text file (class requirement).
The file is read in the Page_Load method and the DropDownList is populated then.
When I press the Submit button, throughout the process of the code it is supposed to get the SelectedIndex and use it to grab a value out of a List(Of ).
The thing is, nothing is ever passed through. I even setup an alert box and it passes right over the alert box and never even triggers it, but gives me an Index out of range error when it moves to the line right after the Alert.

Forms Data Controls :: Setting The Selected Index / Value In A DropDownList?
Feb 8, 2011I have a problem in setting the selected index /value in a drop down list. The list is bound by a Linq query and I want to add an item at the top of the list and set it as the selected item.
THis is the code i am using
ListItem li = new ListItem("Select", "", true);
list.DataSource = (from ap in edc.Approvers
where ! ap.approverEmail.Equals("")
orderby ap.approverEmail
select new {ap.approverEmail}).Distinct();
list.DataTextField = "approverEmail";
list.DataValueField = "approverEmail";
list.DataBind();
list.Items.Add(li);
list.Items.FindByText("Select").Selected = true;
The listItem li is the item i want to be first in the list and also selected. Adding this before the databind just loses the item.
Web Forms :: Preserve DropDownList Selected Index In User Control?
Dec 4, 2010I have a user control that has some drop down lists. These DDLs are used by the user to filter their product search on my search page. A button is used to post the form and get the results of the product search. Those results are displayed on the results page, which also has the search filter user control on it. I'd like the results page to have the values of the DDLs be preserved from the search page. Example: user selected color of red and size of large on the search page. When the results page is displayed, I'd like the selected color to be red for the color DDL and the size to be large for the size DDL. How can I do this?

Web Forms :: Prevent The Firing Of Index Changed Event In A Dropdownlist When 'NO' Is Selected?
Mar 20, 2011I have a simple query based on the index changed event of a dropdownlist in ASP.NET. The scenario is i have a dropdown list bearing a collection of items (say ONE, TWO, THREE, FOUR, FIVE) with the default value selected as 'ONE'. Now, when the client changes the index (say the client selects 'TWO'), a confirmation box is prompted asking 'Are you sure want to change the index?' with the buttons YES & NO. Now, the problem is, if YES button is clicked then its working fine as the index is changed. But when NO button is clicked in the confirmation box, I do not want the index to be changed to 'TWO' and it should be holding the previously selected value which was 'ONE'. How can I do this? For which event should I write the code, as I cant think of writing the code for the IndexChanged event because here the index change has already occured and since there is no 'IndexChanging' event in ASP.NET, where shall i write the code
