What is the best way to get the value of a dropdownlist control before it has been changed and after it has been changed. Can it be done in one routine? In other words, if a user clicks on a dropdownlist control and changes it's value, I need to get the old value and the new value and send both these values as input parameters to a stored proc.

I wanted to create a dropdownlist that would trigger an asynchronous postback and update the Gridview inside the Updatepanel. However, no matter what I do, when the dropdownlist changes, nothing in the UpdatePanel will change, even the TestLabel....I've been banging my head against the walls for days on this -- why won't this work? When I remove the UpdatePanel code and triggers, all the code works, eg, you change the dropdownlist andthen gridview updates -- but it refreshes the page and this is why I wanted to put the Gridview inside an Updatepanel to make it look cleaner.[Code]....

[URL]Initially if I make a selection it will automatically post back and firecboItemsPerPage_SelectedIndexChanged. If I then post back by clicking one of the other buttons on the page, cboItemsPerPage_SelectedIndexChanged will continue to fire, despite the fact that the value has not been changed.I want it to be postback only when selected index is changed, not in every postback
In my application i have a 'Result.aspx' page. In this page i have a dropdownlist which is acting as a master for a gridview. I want that when the user loads this page then the dropdownlist automatically has the value which user selected on another page and for this i am using querystring in the page load event as follows
ddlSelectCoupon.SelectedValue =Request.QueryString("partID")
I have set the autopostback of dropdownlist to True
My problem is if i am assigning the value to dropdownlist this way then my child gridview is not updating. Also, what is the best page event for assingning this value
I'm having problems binding controls at runtime. I've some user controls which need to be bind to the page when one of the dropdownlist selected index changed.
I can able to bind them properly but when if there is any postback event happens I am losing the controls and control values which were created runtime.
How do I avoid binding them again and again.
I 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
View 7 Replies I am trying to use Yes No Confirmation Message Box but the code below here which i found here uses a button to raise the confirmation message box but what i would like to use is a DropDown. How can i modify the code and i use drop-down box instead of using a button? here is the javascript code:
<script type = "text/javascript">
function Confirm() {
var confirm_value = document.createElement("INPUT");
confirm_value.type = "hidden";
confirm_value.name = "confirm_value";
[code]....
but here is what i would like to use is drop-down instead of the button:

<asp:DropDownList ID="ddl" Width="300px" runat="server" AppendDataBoundItems="true" OnSelectedIndexChanged="ddl_SelectedIndexChanged">
<asp:ListItem Text="test1" Value="test1"></asp:ListItem>

I would like to perform a postback when the droplistlist selected value changes, but only if it was changed via expanding the downdown and clicking an option, not is the user tabs to the control and uses the arrow keys. The reason for this is simple, keyboard accessibility.
View 1 Repliesi have 2 drop down list on my web page
-the first one bound to a sqldatasource and it's work fine
-the second one bound to a sqldatasource (with a parameter depends on the first drop down list selected value )and it's work fine too .
But when a user make a selection on the second drop down list, any post back on the page will return the second drop down list selected index equal to 0.I tried so hard (ON MSDN) to understand why this happen only on this drop down list.
I am using SelectedIndexChanged in the DropDowList and it works fine and populates a GridView based upon a site selection.
Is there there a way I can reset the SelectedIndexChanged so if user wants to refresh the GridView they would open the drop down list and click on the same selection again?
GRADING: EXCELLENT VERY GOOD GOOD FAIR POOR

In the above dropdownlist when i select the Poor from any of the dropdownlist, popup screen will open in that one textbox is there reason for poor will type. Then I have one ok button and click that button. When I select the any dropdownlist from the above, commonly one popup will be open if we select the above dropdownlist in that popup screen one textbox is there reason for pooor will type.
My question is how do you know which dropdownlist is selected and give the reasonf for poor. For that how can i do in asp.net.
i can populate cascading dropdownlist by using webservice now. but may i know how do i trigger function while selectedindex changed? (without using auto postback...)
View 3 RepliesI know we can set autopostback property of dropdwonlist using javascript or jquery and it will go to action controller specified in Form tag.
[Code]....
but how can we set it to some different action other then what we specified in Form Tag.
<asp:DropDownList ID="ddlday" Width="100px" runat="server" CssClass="iselect" Autopostback="True"
AppendDataBoundItems ="true">
<asp:ListItem Text="--Select--" Value="0" />
<asp:ListItem Text="Full" Value="1" Selected="True" />
<asp:ListItem Text="Half" Value="2" />
</asp:DropDownList>
I have a dropdown in gridview. I bind the gridview after not ispostback condition. Now if i select drodown lsit value "Full" from the first row of gridview i need all other rows of dropdown in gridview to be selected "full" programtically and after that if the user wants to change other row dropdown to "half" then he can change it.
I'm trying to do a similar thing -- I have a long form and in part of it, I have an updatepanel.
Inside the updatepanel I have:5 dropdowns (using the CascadingDropdown functionality)One AddProduct ButtonGrid or Repeater (haven't set it up yet)
I want the following to happen:I have the AddProduct Button disabled initially, but I want it to be enabled once the 5th dropdown is selected (so OnSelectedIndexChanged).If they click the AddProduct button, I want it to populate a Grid or Repeater.So far I am just trying to show what the selection was in a label... but nothing happens. I have an OnSelectedIndexChanged function for the last dropdown, so it enables the button, but that doesn't appear to get called. Previously, before disabling the button, I tried updating the label on button click -- and nothing there either.
It just seems like, because they are in the updatepanel, those callbacks never happen. I also do have UpdateMode = Conditional and I have both items in the triggers list.
I want to create a drop down list, where user can view the code name and the name the code when they click on the drop down list.
But after they choose, only the code is appeared. This is my current coding as for now.
<asp:DropDownList ID="ddlcodetype" runat="server">
<asp:ListItem Selected="True">-</asp:ListItem>
<asp:ListItem>DK Deck</asp:ListItem>
<asp:ListItem>EG Engine</asp:ListItem>
<asp:ListItem>CT Catering</asp:ListItem>
<asp:ListItem>OT Others</asp:ListItem>
</asp:DropDownList>
With this, both my name and the code name are appeared.
