DropDownList Within GridView - Update Row With OnSelectedIndexChanged?
Apr 4, 2011
I have a list of items in a GridView, with one column I'd like editable through a DropDownList.I do not wish to put the GridView into 'edit' mode or have any 'confirm/update/save' buttons.. I just want autopostback on the DDL, and an OnSelectedIndexChangedevent to update the row.Problem is, from my OnSelectedIndexChangedevent within the DDL, although I can see the new value to save, I can't discover the row to update from the GridView.Can anyone see how I can achieve what I wish? Other than perhaps storing the row id within the DDL? Maybe turn it around so the GridView's events are called?

I have a gridview where the dropdownlist is built during the RowDataBound event. I need to be able to poup a window based on the selection from the dropdownlist Items.
I cannot use Repsonse.Write("window.open('link');") coz i will need to redirect to the webpage which clears out the search on the page.
I need to be able to open a new window with the link and continue executing code on the page.
I have tried,
1) Page.ClientScript.RegisterStartupScript(Me.GetType(), "openwindow", "window.open('" & link & "');", True)
2) Dim s As System.Windows.Forms.HtmlWindow s.Document.Window.Open(link, "", "", False)
3) Process.Start(link) - this works locally but dosent on the testbox

I have an application where I have a dropdownlist with AppendDataBoundItems set to true. This allows me to add a select all ListItem with a value of "-1". I store the selected value in a session so that the selected value is retained if a user navigates away from the page then returns. This works fine for all values except for when the value is set to the appenddatabound item (All). When I debug i can see that the onselectindexchanged event does not fire when the 'All' item is selected. If a user navigates away from the page and comes back this 'All' value is lost as it is not stored in the session.
find my code below:
<asp:DropDownList ID="ddlTeams" runat="server"
DataSourceID="odsTeams" DataTextField="Team_Name" cssClass="ddl"
DataValueField="TeamID" AutoPostBack="True" AppendDataBoundItems="True"
onselectedindexchanged="ddlTeams_SelectedIndexChanged">

I have a DropDownList that is supposed to redirect the user to a page when they change the selected index of the DropDownList. I have three parameters that are being passed by this redirecting. The first time the user changes the selectedindex, it does not work. but every time after that it works.

How would I get the previous item on DropDownList before OnSelectedIndexChanged fires the event?
I had a DropDownList that has names as its items ("John", "Mark"). By default the SelectedIndex is "John". Upon changing its index and selecting "Mark" the event OnSelectedIndexChanged will be triggered. When I use ddlName.SelectedIndex it will return only the index for "Mark" which I want to get is the index of "John".

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 am new to asp.net (I may use some incorrect termology while I explain my issue...) and need some help with DropDownList in Gridview. Currently I have a GridView set up with three Columns bound to a database: Column1 - some kinda of index, Column2 - string, Column3 - DropDownList(called Active). So far when I build the page, all the columns show up and the DropDownList appears and the values are bound correctly. I want to change a value in the DropDownList and automatically update that value in my database.
I have set AutoPostBack = true and I made a DataObject (called UpdateActive) to update the database (it takes 2 inputs, the Column1 index and Column3 DropDownList value).However, I don't know how to find the row that I am changing, is there a way to figure out what row it is (like finding the Column 1 index?). Also, I don't want to have to click a button to update the data.

during edit mode i populate the drop down in question with data based on a value selected in another drop down also in the gridview, all works find, but the paramater is not being updated with the selected value, i think this is because i do not call any Bind in the aspx side.

I have a GridView with a DropDownList in it bound to the [Applicants] table in SQL Server 2005.
The DropDownList Items Text and Value come from SqlDataSource3, "SELECT VoucherType, VoucherNumber FROM [Vouchers]"
I need to send the DDLs selected Text to [Applicants].[VoucherTypeIssued] and the Value to [Applicants]. VoucherNumber]
I already have a "dlVoucherTypeIssued_SelectedIndexChanged" event in the code behind to put "Voucher Issued" into [dbo].[Vouchers].[VoucherStatus]. I'm having trouble getting all three values written to the database at the same time.

I searched a lot of threads but still couldn't get my problem fixed. I have to update the "regform" table with two fields: session_ and session2. These two fields are inside the detailview edititem template which bounded to dropdown list drpsession1, drpsession2 separately. I wanted to pass the update parameters to the update sql UPDATE dbo.regform SET session_=@session_, session2=@session2 where id=@id
the @session_ is bounded to a drpsession1 and @session2 is bounded to drpsession2. I used
ControlID="ctl00$ContentPlaceHolder1$DetailsView1$drpsession1" to access the dropdown list within the detailview, but still couldn't do the updates. What's wrong with my code? Do I have to use the code behind to specify the update parameters? and How to do it? TIA.

What I would like to do is:
From a textbox, I add a name for a product and create a object with that name.
The product object is then added to a Dictionary.
Then, I want to bind this Dictionary to a dropdown list.
If I change the selected item, I want to display the number of the chosen product (Default as 0 when I create the product object).
The problem is that when I try to change the item in the dropdown list, nothing happens.
.aspx
<asp:TextBox ID="productText" runat="server"></asp:TextBox>
<asp:Button ID="newProductButton" runat="server" OnClick="newProduct_Click" />
<div>
<asp:DropDownList ID="ddlProducts" runat="server" AutoPostBack="true"
