It sounds like the value you're using does not already exist in the list of
values in the ListBox.

Hi subhar:

Your ListBox control is trying to set the selected value to val, but
val does not exist as an option in the ListBox. You need to find out
why you are setting val to an illegal value, which is something we
cannot answer looking at this bit of code.

HTH,

Scott,
Below is the full code which ,where my list box is accessing the
"val" value.
//code/////

public void setValue(DataRow row)
{
String val = null;
if(row[columnName].GetType() != typeof(DBNull))
val = (string) row[columnName];
else
val = "";

if(control.GetType() == typeof(TextBox))
((TextBox)control).Text = val;
else if(control.GetType() == typeof(ListBox))
{
//if(val.Length > 0)
((ListBox)control).SelectedValue = val;


}
else if(control.GetType() == typeof(Label))
((Label)control).Text = val;
}
// code end here-------------------------
Below is the asp.net tracing

You might want to step through the code with the debugger and see what
is in the following line of code:

val = (string) row[columnName];

It would appear this does not return a value that is in the list.
You'll need to reconcile these differences, either by adding all
possible value for that column into the list, or restricting the
values appearing in the column with your SQL query (assuming this is
coming from a database).

Hi,
I am facing similar problem, but coulnt fix the bug.
I thing its not bug in our code but in .NET Framework itself.

I am using a global function to bind the dropdownlist

code
Public Sub BindComboBox(ByRef cmb As DropDownList, ByRef sql As
String)
Dim dv As DataView
dv = GetDataView(sql)
cmb.DataValueField = dv.Table.Columns(0).ColumnName
cmb.DataTextField = dv.Table.Columns(1).ColumnName
cmb.DataSource = dv
If dv.Count > 0 Then
cmb.DataBind()
End If
End Sub

I have used this sub in some other page which is working fine. Not just
that but it worked well till last monday, But its giving me errors now,
which i am not able to fix.

In debug mode, i traced down the values, and found the query (sql) what
i am passing is returning 2 rows.

I am worried about the mistifying behaviour of .NET which with same
piece of code works some times and soemtimes doest.

Gurus..., have any clue?

You say the data has 2 rows, but are you sure the result also has at
least 2 columns?

 

[Billy Bob]

yes, if you absorve my code I am using dv.table.colums(0).columnname

If it didnt getch the 2 columns, in my code, the very next code would
give index out of range error, isnt it?.

But after long hours I solved it.

NOW I AM ROLLING BACK MY WORDS I SAID ABOUT .NET FRAMEWORK.

It was a small mistake(no its big), which was accidently modified by me.

after finding the grid, i was suppose to select the username with the
userid which i fetched from db.
For that instread of giving combobox.selectedvalue=datafieldvalue i gave
datatextvalue

it was something like this, i have userid and username columsn fecthed
and binded combobox

in my code to select the desired user in combobox, i gave
cmbReportsTo.SelectedValue=somevalue
somevalue should be userid (but i gave username value)

thats it.

bye

Hi subdhar,

Is your problem resolved?
I thing the val at
Line 122: ((ListBox)control).SelectedValue = val
in your code is returning the DataTextField, it should match with the
DataValueField.

The default value is set as "U" as the default value in the database is
'U',Somehow .Net didn't like this string value "U".As I was debugging
someone code,I couldn't make out where this value is coming.Even if the
default value is set "U",It's giving under paramemter error.I trick the
code and make the code works.

Thanks
