I have the following structure 3 Dropdown Boxes, the 2nd and 3rd dependant on the 1st and when I change the first combo the pages refreshes with error I am assuming it's happening when posting back. I have nothing in my code behind file for this page so far.
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
This is a very Basic application that I am creating using Visual Basic and ASP.Net 3.5. Am using a SQL Datasource have searched for this error some of the answers seem extremely complex and I can't figure them out, surely a simple tasks like this has to be easy to bind back to the database from several drop down lists.
I have a formview in which I have a dropdown list that displays a list of owners. In case the list does not have the correct owner for the user I have added functionality for them to add a new owner to the database table that populates the list. I did this by including a textbox and an Insert button in a panel. When the user clicks the new owner insert button I would like to re-databind the dropdown list so that they will see the owner they added and be able to select it.
When I add ddl_owners.databind to my button click code it gives me an error. "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
I don't want to re-databind the entire formview because then it deletes all the information on the form that the user has already keyed in.

I'm trying to bind a selected user's role to a dropdown-list. The purpose of this is to be able to change said user's role.
I'm attempting this inside a formview hooked up to a linqdatasource which contains a row from the aspnet_User table.
The dropdown list is hooked up to a linqdatasource of all the roles in the aspnet_Roles table (with DataValueField="RoleID", DataTextField="RoleName").
I figured it would be possible with something like:
SelectedValue='<%# Bind("aspnet_UsersInRole[0].aspnet_Role.RoleID") %>'
But this throws a parser exception, about the bind call not being correctly formatted.
The roles are there, they show up when I remove the "SelectedValue"
I have a BLL where in I am getting all the data from a table. Now I want to populate a dropdown with one of the field in this BLL.
ddlstatus1.SelectedValue = dt.Rows(0).Item("StatusCode") and this is not working.
I tried ddlstatus1.SelectedIndex = dt.Rows(0).Item("StatusCode") too but this is throwing an error that string cannot be converted to Integer.

I have a Gridview and on the OnRowCommand of that GridView I want to Bind the data for another Gridview, but everytime I do that nothing gets bound to the Second Gridview.
View 3 RepliesI have a small issue binding the values into a dropdown using LINQ in ASP.NET code-behind.
var clientquer = from i in Entity.New_Bank select i;
//var q = (from s in names
// select s).Distinct();
// var getlendername = (from db in mortgageentity.New_Lender group db by db.Bank_Name into t select t.Key).ToList();
if (clientquer.Count() > 0)
{
ddlbankname.DataSource = clientquer.ToList();
ddlbankname.DataValueField = "Bank_ID2";
ddlbankname.DataTextField = "Bank_Name";
ddlbankname.DataBind();
}
It is binding with duplicate values, but I don't want bind duplicate values. I'm trying to solve this by using a group by clause, but it is not working.
