DataGrid and a DropDownList

I've got a template column in a datagrid which consists of a dropdownlist. I am handling the selectedindexchanged event of the dropdownlist, no problem. But what I want to do, is this:

If the selected index of the dropdownlist in row #7 changes, I'd like for a textbox in that same row to be enabled.

This was easy with the DataGrid's ItemDataBound event. All I had to do was:

Code:

---

DropDownList ddl=(DropDownList)e.Item.FindControl("cmbLeaveType");
string strLeaveType = ddl.SelectedValue.ToString();
TextBox txtTDT = (TextBox)e.Item.FindControl("txtToDateTime");

switch(strLeaveType)
                                        {
                                                case "LeaveWithoutApplication":
                                                        txtFDT.Enabled = false;
                                                        break;
// and so on

---

Thing is, I don't know how to access the "correct" textbox or control.

Any guidance?

I hate solving my own problems. :(

In the HTML, I gave a name to the OnSelectedIndexChanged handler.

In the codebehind,

Code:

---

DropDownList ddl = (DropDownList)sender;
                        string strLeaveType = ddl.SelectedValue.ToString();

                        int counter;
                        DataGridItemCollection DataGridItems = dgEditLeave.Items;
                        for (counter=0; counter<DataGridItems.Count; counter++)
                        {
                                DropDownList ddl1 = (DropDownList)DataGridItems[counter].FindControl("cmbLeaveType");
                                if(ddl1 != null)
                                {
                                        if (ddl.ClientID ==  ddl1.ClientID)
                                                break;
                                }
                        }
                       
                        TextBox txtTD = (TextBox)dgEditLeave.Items[counter].FindControl("txtTotalDays");
                        //dgEditLeave.Items[counter].FindControl("");
                       
                        if (strLeaveType=="CompensatoryOff")
                        {
                                txtTD.Enabled = false;
                                txtTD.Text = "HELLO";
                        }

And uhm... that's it.
