DROPDOWN SELECTEDINDEX PROBLEM

[in da club]

I have a datagrid and a dropdown in my page. I want to fill dropdown with my
pagenumbers. When a user change the dropdown selected index i wnt to display
the result on label1. Anytime i change the dropdown index it returns zero ..
What is the problem ?

private void Page_Load(objec t sender, System.EventArg s e)

{

int TotalP=0;

SortedList hash =new SortedList ();

SqlConnection baglantim=con.M yConnect ();

for (int j=1;j<5;j++)

{

hash.Add (j,j);

}


dd.DataTextFiel d ="Value";

dd.DataValueFie ld ="Key";

dd.DataSource=h ash;

dd.DataBind();
if (!Page.IsPostBa ck )

{

DataGrid1.DataS ource = con.FillGrid (baglantim,0);

DataGrid1.DataB ind();

}

}

private void dd_SelectedInde xChanged(object sender, System.EventArg s e)

{

// Label1.Text =dd.SelectedInd ex.ToString() ;

string PageN;
PageN=dd.Select edIndex.ToStrin g();

Label1.Text = PageN;

}

Hi I have faced the same problem a long time back. I cameup with other
solution.

Instead of using the selectedIndex property , use SelectedItem
property.

I got it from my page..
<option selected="selec ted" value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>

i tried the following it always returns 1 .. No change..
private void dd_SelectedInde xChanged(object sender, System.EventArg s e)

{

// Label1.Text =dd.SelectedInd ex.ToString() ;

string PageN;
PageN=dd.Select edItem.Value;

Label1.Text = PageN;

}

You should probably cast "sender" to a DropDownList and use that instead of
"dd".

ok i solved the problem . The problem is that SelectIndexChan ged event fired
after Page_Load event. Then I checked my code and solved it..
