The below line set the text in the textbox inside the gridview

((TextBox)DtClass.FindMyControl(GridView,"TextBox1 ")).Text="hi";

Below is the code for finding the id of a control and doing an action with it,say finnding the textbox id inside a grid.


public static Control FindMyControl(Control c, string s)
        {
            Control found = null;

            for(int i = 0; i < c.Controls.Count; i++)
            {
                if(c.Controls[i].UniqueID.EndsWith(s)==true)
                {
                    found = c.Controls[i];
                    break;
                }
                else
                {
                    found = FindMyControl(c.Controls[i], s);
                    if(found != null)
                        break;
                }
            }
            return found;
        }

how do you convert the same code in vb.net.i did convert , but i am getting error of object reference not set to an instance of an object.
below is my vb code.

 Public Shared Function FindMyControl(ByVal c As Control, ByVal s As String) As Control
        Dim found As Control = Nothing
        Dim i As Integer = 0
        Do While (i < c.Controls.Count)
            If (c.Controls(i).UniqueID.EndsWith(s) = True) Then
                found = c.Controls(i)
                'TODO: Warning!!! break;If

            Else
                found = FindMyControl(c.Controls(i), s)
                If (Not (found) Is Nothing) Then
                    'TODO: Warning!!! break;If
                    GoTo p


                End If

            End If
            i = (i + 1)
        Loop
p:
        Return found
    End Function

Hope this is the right one.(Please tell me if any error is there above.im new to vb.net)

 CType(DtClass.FindMyControl(GridView1, "TextBox1"), TextBox).Text="hi"

while running the code im getting error object reference not sat to an instance of an object.
