how to bind data in an ItemTemplate column in my Gridview.
I have created an ObjectDatasource on my page bound to my Gridview using a Dataset from my linked SQL tables (PKs, FKs,etc...).
I am showing all my USERS table data in my Gridview but there are some columns which are ID's being displayed such as MembershipID, UserTypeID. These ID's are my foreign keys to other SQL tables.
I have easily been able to go into my EditTemplate for these columns, attach a new ObjectDataSource as a Lookup table, add a new DropDownList in place of the TextBox and then set Two-way binding so that the MembershipName & UserTypeName's are displayed for editing.
However, I cannot seem to work out how to do this Binding to the other ObjectDataSources in the ItemTemplate Label. Again i can make it work witha DDL, but i don't want any selections when just displaying the data in the Grid. I simply want the name to be shown in a label, but cannot work out the binding lookup?
I have various difficulties handling dropdownlist in listview itemtemplate.Hopefully, resolving this example will help me understand how to make things work.I need to do several things upon DropDownList1_SelectedIndexChanged.(1) Fetch row index of listview then set the row as listview selected, or vice versa, in which dropdownlist was changed.(2) Fetch text of namelabel in that selected listview row.(3) Fetch selected text of dropdownlist in that selected listview row.
[Code]....
At the moment...(1) Label1.Text = ListView1.SelectedIndex always shows '-1' regardless in which row dropdownlist is selected/changed.(2) Label2.Text = NL.Text pops 'Object reference not set to an instance of an object'.(3) Label3.Text = DDL1.SelectedItem.Text pops 'Object reference not set to an instance of an object'.

View 1 RepliesI have a dropdownlist - ddlGroupName. Next to it, I have a Label - lblGroupName. The dropdownlist is bound to an SQL table, and displays the appropriate group depending on the primary key (contracters, suppliers, etc etc). When the page loads, I want the Label to display whatever is in the dropdownlist, then I can hide the dropdownlist and am just left with the label. I was using "lblGroupName.Text = ddlGroupName.SelectedItem.Text;", but intellisense doesn't seem to acknowledge the controls when they're in an ItemTemplate.

View 1 Replieson SelectedIndexChanged event handling of DropDownList in ItemTemplate of ListView. I put OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" in mark up, with code behind, but only to get Compiler Error Message: BC30456: 'DropDownList1_SelectedIndexChanged' is not a member of 'ASP.webform1_aspx'. How do I make it a member? When I do not put OnSelectedIndexChanged="DropDownList1_SelectedIndexChanged" in mark up, BC30456 does not pop up, but nothing happens when dropdownlist selected item is changed.

What I have is a GridView with a DropDownList in an ItemTemplate (not an EditItemTemplate). My datasource is not a control, rather in the code-behind.
[Code]....
My main problem is that VS is not seeing that I have the dropdownlist, meaning I can not access any of the events in the code-behind. What I want to do is, when the value of the DropDownList is changed (SelectedIndexChanged), I want to grab the value of the RowIndex of the GridView.

I read your article on ASPSnippets and everything worked great. I am having one problem and this is preventing me from moving forward. When I select the edit for a row (I only have two columns), the drop down comes back blank (no records). I have looked at the code multiple times and can't see where I made a mistake. is it possible to control the width of the drop down list? I can't tell if the column automatically adjusts because I am not returning any records.

Am trying to bind data to a dropdown list on pageload based on a condition. Code explains further below.
public partial class AddExhibit : System.Web.UI.Page {
string adminID, caseIDRetrieved;
DataSet caseDataSet = new DataSet();
SqlDataAdapter caseSqlDataAdapter = new SqlDataAdapter();
string strConn = WebConfigurationManager.ConnectionStrings["CMSSQL3ConnectionString1"].ConnectionString;
protected void Page_Load(object sender, EventArgs e) {
adminID = Request.QueryString["adminID"];
caseIDRetrieved = Request.QueryString["caseID"];
if (caseIDRetrieved != null) {
CaseIDDropDownList.Text = caseIDRetrieved;
//CaseIDDropDownList.Enabled = false;
} else { try { CreateDataSet();
DataView caseDataView = new DataView(caseDataSet.Tables[0]);
CaseIDDropDownList.DataSource = caseDataView;
CaseIDDropDownList.DataBind(); }
catch (Exception ex) {
string script = "<script>alert('" + ex.Message + "');</script>";
} } }
The CreateDataset method that is called in the if..else statement is contains the following code.
private void CreateDataSet() {
SqlConnection caseConnection = new SqlConnection(strConn);
caseSqlDataAdapter.SelectCommand = new SqlCommand("Select CaseID FROM Cases", caseConnection);
caseSqlDataAdapter.Fill(caseDataSet); }
However when I load the page and as usual the condition that is supposed to bid the data is met, the gridview decides to displays as follows. Is it me or its the Datagrid?
I am working with a webdatagrid control. It is fairly simple in that it has Three template columns. Each column contains a separate control; a dropdownlist, webdatepicker and a command button. The webdatagrid is populated using ado.net code and the dropdownlist is populated using a sqldatasource object. I have a command button external to the webdatagrid that I am using to try and add a new row to the webdatagrid. The intention is that a new row will be created at the bottom of the grid that will contain each of the three controls, including having the dropdown populated. I cant seem to find the correct code to do this. I have tried several methods and it has been going on for some time. Can someone tell me if t is possible to do this and if so can they point me in the right direction?
