Forms Data Controls :: Can't Get Dropdownlist From Gridview With Javascript
Aug 30, 2010
I need to loop through each row in the Gridview and then get the selected value for each rendered Dropdown. I need each value to calculate totals. So I declared a javascript function which loops through the grid rows on the 'onchange' event of the dropdowns. I can retrieve the text from other columns, but I can't get the dropdown. My code:
[Code]....
The gridview is just plain grid with itemtemplate fields for the dropdown... nothing special. I used an alert to see what I get, but I keep getting an error on the 'window.alert' line which says "'options' is null or not an object". If I use the same code on normal dropdown that's not in a gridview, it works just fine. I've been Googling all morning, but nothing seems to work or I don't get what I'm looking for.

I have a GridView, the first column it's a RadioButton template and the second it's a DropDownList Template, the number of rows depends on the user, I mean they are not static. I'm using the following JS function to get the row selected with the radiobuttons:
[Code]....
With this function I know which RadioButton was selected, now, I would like to get the DropDownList value or text of the selected row, I know I have to loop through every DropDownList to get an array of controls, but since they are something like ctl00_ContentPlaceHolder1_GVProducts_ctl02_DValsDropDown, I just don't know how to achive this through JS.

I have a gridview in which I have two drop downs. One is populated with values that are static, so I have a regular sub that does that in the code behind. I tried to add code for databinding the other ddl to a datatable. I cannot get this to work. It just comes up empty. My asp code is fine, and the datatable definately has data in it - just nothing gets populated.
One other thing - the code for the static ddl has worked fine, but when I add this other block (either to the same sub as that, or dow the rowdatabound event) the static one doesn't work either.

I have a gridview that holds 4 columns. in the fourth column there is a DropDownlist that holds three items.
I want my users to select one of the values and when they do the auto post back (which is set to true) should execute a method that updates the database selected row. But do i use the selectedindexchanged of the DDL or the Gridview? My head is totally thrashed so i imagine its really simple and im just over thinking it.

I have an application that contains a GridView and a DetailsView I use to maintain records in a Facility table. The Facility table contains a County "ID" field that show the ID of Country the Facility is located in. Example Facility Table: Facility = New York Country ID = 1. In the Country table: Record 1 = USA and so on.
I want to add a DropDownList in this Facility Maintenance app that displays the actual Country names to select from - not the country ID. I know how to code DropDownList with no problems but this multiple files thing is confusing me.
In the Edit and Insert modes, I want to display the Country "name" but when writing or updating the Facility table I want to write the "ID" of the Country selected of course. I am not sure how to setup my QueryBuilder in my SqlDataSource to accomplish this. I have tried several things but not working. I can display the Country names but get errors when trying to write to the Facility record.

<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True"
AppendDataBoundItems="True">
<asp:ListItem Value="1" Selected="True">A Type</asp:ListItem>

I've seen several examples here but for some reason I still cant get this to work. I have a gridview of user information.
userid name phone role
00001 john 12345 [downdownlist]
00002 jack 12345 [downdownlist]
00003 jeffz 12345 [downdownlist]
00004 jims 12345 [downdownlist]
The code would look something like this:
<asp:GridView
ID="gvUsers"
runat="server"
AutoGenerateColumns="False"
DataSourceID="dsUsers"
DataKeyNames="id"
[Code].....
So as my example code above shows, I'm trying to build a dropdownlist within the gridview. The datasource for the dropdownlist is based on the userid. The two datasources (dsUsers, dsRoles) are two different tables in the database. HOw can I implement the dropdownlist to use the userid from the gridview to query the dsRoles to populate its list?
