  TextBox txtLeatherdate = dgvMain.Rows[e.RowIndex].FindControl("txtLeather_date") as TextBox;
  TextBox txtInsidedate = dgvMain.Rows[e.RowIndex].FindControl("txtInside_date") as TextBox;
  TextBox txtOutsoledate = dgvMain.Rows[e.RowIndex].FindControl("txtOutsole_date") as TextBox;
  TextBox txtNotes = dgvMain.Rows[e.RowIndex].FindControl("txtNotes") as TextBox;
}

  <EditItemTemplate>
<asp:TextBox id="txtSchedule_date" runat="server" Width="89%" CssClass="inputText" Text='<%# Eval("Scheduledate") %>' >
</asp:TextBox>
</EditItemTemplate>
 protected void gv_RowUpdating(object sender, GridViewUpdateEventArgs e)
       {
     
           string strId = gvRole.DataKeys[e.RowIndex].Value.ToString();

           string str = ((TextBox)gv.Rows[e.RowIndex].FindControl("txtSchedule_date")).Text.Trim();
     }

[解决办法]
      protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{       
sqlcon = new SqlConnection(strCon);      
  string sqlstr = "update 表 set 字段1='"            + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[1].Controls[0])).Text.ToString().Trim() + "',字段2='"            + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[2].Controls[0])).Text.ToString().Trim() + "',字段3='"            + ((TextBox)(GridView1.Rows[e.RowIndex].Cells[3].Controls[0])).Text.ToString().Trim() + "' where id='"             + GridView1.DataKeys[e.RowIndex].Value.ToString() + "'";      
  sqlcom=new SqlCommand(sqlstr,sqlcon);       
  sqlcon.Open();       
  sqlcom.ExecuteNonQuery();    
    sqlcon.Close();      
  GridView1.EditIndex = -1;

[解决办法]
string aaa=Convert.ToDecimal(((TextBox)(ProGridView.Rows[e.RowIndex].Cells  [4].Controls[0])).Text.ToString().Trim());
[解决办法]
C# code
TextBox txtScheduledate=(TextBox)dgvMain.Rows[e.RowIndex].Cells[0].FindControl("txtSchedule_date");//或者：TextBox txtScheduledate=(TextBox)dgvMain.Rows[e.RowIndex].Cells[0].Controls[1]
[解决办法]
LZ 你为什么一定要用控件啊。。。循环一个表格不行吗？ 
 
对简单啊。效率还好
[解决办法]
foreach(GridViewRow row in GridView1.Rows)
{
TextBox tb=row.FindControl("TextBox1") as TextBox;
tb.Text="";
}
[解决办法]
TextBox txtScheduledate = dgvMain.Rows[e.RowIndex].FindControl("txtSchedule_date") as TextBox;  


你这样是定义一个变量txtScheduledate（他是个TextBox类型的）要取值，你还得
strin aaa= txtSchedudedate.text.toString();
