View 6 RepliesI have a project that queries a set of times from a database and uses these entries to populate a dropdownlist. Once the page is loaded, the user can select one of the items in the DropDownList. When the "Save" button is clicked, the Selected item value is returned to the [HttpPost] version of the controller action. This item is then stored into session. If the system returns to the page containing the dropdown, I want the saved Value to be selected in the DropDownList. What actually happens is that the DropDownList is always set to be the first item in the list.

I have items in a sql table that i populate a dropdown list with. so on page load the items are sent to dropdown list. I have a button on the page with the dropdown list that onclick it launches another page that allows more items to be added to the database table.
What I want to do is to refresh/update the list of items in the dropdown list when the second page is closed. In addition the last item added to the table will be the selected item in the drop down list.
I am inserting a new states in the table from dropdown list , the dropdown list has new in the list, clicking on new gets me a pop up which takes the new state and inserts in a table. My requirement is I want to get the last inserted state in the dropdownlist and its id to be selected as soon as insertion is done.
The second function is to insert the contact details where i have countryid,stateid,cityid

I have an optional DropDownList. If the user dosen't select any value the top most value is "0" unfortunatly the only way to send DBnull.Value to the database is check if the value is 0 and if it is then send dbnull. Is there a way you can do this within the dropdownlist without having to check for each and every dropdown?

I'm not getting any error but the 'if' is being skipped - the value of row.Cells[5] is not being read.
I would like to be able to pass a new value into a dropdownlist control from another webpage and cause an autopostback to occur. How can this be done?

{
for (int i = 0; i < dt.Rows.Count; i++)

why i cannot use the above method to add item to different dropdownlist by passing different parameter?
I have a formview that when in insert/edit mode, has a dropdowlist and a linkbutton. The linkbutton opens a popup with another formview that allows the user to enter new items that are required to be added to the dropdownlist. When the popup closes, it adds any new items to the dropdownlist options (there may be more than one item added). The purpose is to prevent having to have my users partially add/update a record, go create a new item for the dropdownlist then have to come back and edit again since any new items won't be known until they are needed.
At first, I recieved the 'invalid postback or callback' warning and began reading up on the issue. Though there were several forum posts and web articles, most seemed a few years old so I thought I would find out if there were any subsequent changes that might help me out. I'm using vwd2005/ASP.Net 2.0 and do not have ajax (not available on my corporate web servers). In the page directives, I disabled EnableEventValidation but then I found that while other controls were updating, the value set in the dropdownlist was not and I had to make 2 edits anyway. Since new items in the ddl won't be around when it is rendered, i've read that I can't make use of registerforeventvalidation. ps. i have thought that i could save my viewstate, browse away from the page instead of use a popup, then restore the viewstate, but I'm concerned about being able to update the ddl while retaining the viewstate.
I have been having some trouble with dropdown lists reverting back to selecting the initial item in the list after a postback once a selection has been made from the dropdown list. I have read up on this and found out that a "if not ispostback then" is required.This works fine when I add in all the items in the dropdown list manually like:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
ddl1.Items.Add("Select...") [code]....
However, I have over 250 items and so it is far more efficient for me to load then in by using part of a multidimensional array which is created from a text file - Definitive database.txt. I have been using the following code to do so:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
'loads the definitive database array[code]...
This loads all the items into the dropdown list perfectly, but now every time a selection is made, it reverts back to the inital item on postback even though i have included the "if not ispostback then" part.
I want to compare each item in a dropdownlist to a value and if the item matches the value, I want that ddl list item to be 'selected' and showing...
why doesn't this work:
[Code]....
based on the below image, May i know how if tick the checkbox, then will hide the selected data value only.
Example, hide "a", then will hide "a" data value only.
