Forms Data Controls :: DropDownList In GridView Using Two Files
Mar 31, 2011
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.

I have a small website with a database. Just two tables for personaldata and for files belongs to the personal data.
This files are stored on HD. My problem is to delete this file by clicking on delete button within gridview. At the moment only the record is deleting but not the file which belongs to this record.
That is my Gridview:
[Code]....
and that is my codebehind file:
[Code]....
and see the screenshot. (how it looks like)
i get allready help here to create the right codebehind file for that.
i have tried that this way:
[Code]....
But i think instead of txtFile.Text the filename of thefile should be readed out of the database on this place or Im wrong?

We have a MS Access 2007 database that has a hyperlink column in one of the tables. I'm using Visual Studio 2008. I need to have the same column display in a gridview in ASP.net and have it function just like in access. In access, the user clicks the link and either the file or the wepage opens just fine. In the gridview in asp.net, if we click on the link it does "nothing". The links are to files on our network and to files on other people's websites and the paths are tested and work properly. The name of the column that holds the hyperlink is named MSDSLinke. Here is the code I am using:
<asp:TemplateField
HeaderText="MSDS"
SortExpression="MSDSLinke">

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 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 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.

after hours of searching and testing (and found no luck), I came here to ask for your help again. I have a gridview and two dropdownlists. The first dropdownlist (DropDownList1) filters the gridview with Type of Customer. Here is the code on the aspx:
<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?
