I have done in the following manner.

C#

function validate() {
    var flag = true;
    var gridview = document.getElementById('<%=grdprescript.ClientID %>'); //GridView1 is the id of ur gridview.
        
    var texts = new Array();
    
    for (var i = 0; i < texts.length; i++) {
        if (texts.items(i).value == '') //If dropdown has no selected value
        {
            flag = false;
            break; //break the loop as there is no need to check further.
        }
    }
    
    if (!flag) {
        alert('Please Enter Date in each text');
    }

    return flag;
}

Try this in Save button click

C#

foreach (DataGridViewRow row in dataGridView2.Rows)
           {
               if (row.Cells[0].Value == null)
               {
                   MessageBox.Show("Your Message here");
               }
           }

Cells[0] is grids first column you can use any column...

Solution 1

Logic
On Save Button Click Event...

Loop through the GridViewRows
Find the particular Control (TextBox) inside the GridViewRow
Check is its value is null
Show one lable on each row saying TextBox value is null (showing alert for each row is not a good idea)

Solution 3

if (row.Cells[2].ClientID.text.tostring() == 0 || row.Cells[3].text.tostring()== 0 || row.Cells[1].ClientID=="0")
{
alert(); or lblerrormsg.text=" please enter date";
}
// 3 will for dropdownlist
