I have created an asp.net customizable gridview where user will be able to add and delete data. Now I face some proplem with this gridview. now I want to add a dropdown list (which is dynamically bind with database) inside the grid. I created code and it bind well. when the page is post back previous selected dropdown list value lose and set to selectedIndex=0; For this reason I used if(!page.Ispostback) and put the dropdown binding code inside this.

I 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.
I am trying to bind a record to a textbox using a Dropdown selected index change. I get the error.
Conversion failed when converting the nvarchar value 'DrFirstName DrLastName,Ph.D.' to data type int. is it because I concatenate the name and prefix of the DR into the Dropdown list like this,
Code:
SELECT ID,EmailAddress, DrName + ',' + PreFix AS DrName FROM DrNames
Here is the dropdownlist code that I want to populate the textbox with the emailaddress in the table associated with Dr name and ID.
Code:
Private Sub DropDownList1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles DropDownList1.SelectedIndexChanged
Dim dt As New DataTable()
If DropDownList1.SelectedItem.Text = "OTHER,..." Then
txtRx1.Visible = True
DropDownList1.Visible = False
End If

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 have "Testdtabse" it's consists of the Table like aaa,bbb,ccc,ddd,eee etc.. I want to bind that table names in to My droipdown list box..
