How to get dropwdown value from the grid view i am adding dropdown dynamically

Any My Code Behind file
private void FirstName_DataBinding(Object sender, EventArgs e)
{
// Get the Label control to bind the value. The Label control
// is contained in the object that raised the DataBinding event (the sender parameter).
Label l = (Label)sender;

// Get the GridViewRow object that contains the Label control.
GridViewRow row = (GridViewRow)l.NamingContainer;

// Get the field value from the GridViewRow object and assign it to the Text property of the Label control.
l.Text = DataBinder.Eval(row.DataItem, "Links").ToString();

}

private void LastName_DataBinding(Object sender, EventArgs e)
{
// Get the Label control to bind the value. The Label control
// is contained in the object that raised the DataBinding event (the sender parameter).
Label l = (Label)sender;

// Get the GridViewRow object that contains the Label control.
GridViewRow row = (GridViewRow)l.NamingContainer;

// Get the field value from the GridViewRow object and assign it to the Text property of the Label control.
l.Text = DataBinder.Eval(row.DataItem, "Links1").ToString();
}
}

and her's my.cs file

protected void Page_Load(object sender, EventArgs e)
{

////Populate Data
DataTable dt = new DataTable();
dt.Columns.Add("Links");
dt.Columns.Add("Links1");
DataRow dr;
for (int i = 1; i < 10; i++)
{
dr = dt.NewRow();
dr["Links"] = "A" + i;
dr["Links1"] = "B" + i;
dt.Rows.Add(dr);
dt.AcceptChanges();
}
////Grid view
// The field columns need to be created only when the page is first loaded.
if (!IsPostBack)
{
gvTest.AutoGenerateColumns = false;
// Dynamically create field columns to display the desired
// fields from the data source. Create a TemplateField object
// to display an author's first and last name.
TemplateField customField = new TemplateField();
// Create the dynamic templates and assign them to
// the appropriate template property.
for (int i = 0; i < 10; i++)
{
customField = new TemplateField();
customField.HeaderTemplate = new MyGridViewTemplate(DataControlRowType.Header,i.ToString());
customField.ItemTemplate = new MyGridViewTemplate(DataControlRowType.DataRow,i.ToString());
// Add the field column to the Columns collection of the GridView control.
this.gvTest.Columns.Add(customField);
}

// Add the field column to the Columns collection of the GridView control.
this.gvTest.Columns.Add(customField);
BoundField boundField = new BoundField();
boundField.HeaderText = "Bug ID";
boundField.DataField = "Links";
this.gvTest.Columns.Add(boundField);

gvTest.DataSource = dt;
gvTest.DataBind();

}
}
protected void ButtonShow(object sender, EventArgs e)
{


foreach (GridView grow in gvTest.Rows)

In above code your are assigning gridviewrow to GridView and thats the reason for this error. You need change the below line from

foreach (GridView grow in gvTest.Rows)

to

foreach (GridViewRow grow in gvTest.Rows)

Complete Code:

protected void ButtonShow(object sender, EventArgs e)
        {
            //Looping through the rows in GridView
            foreach (GridViewRow grow in gvTest.Rows)
            {
                DropDownList ddl = (DropDownList)grow.FindControl("ddl");
            }
        }
