Add all your required validators to your mark up and enable/disable them in RowDataBound
this example use compare validator that validate a test value:

C#

void Grd_RowDataBound(Object sender, GridViewRowEventArgs e)
{
  if(e.Row.RowType == DataControlRowType.DataRow)
  {
      DataRowView rowView = (DataRowView)e.Row.DataItem;
      String testValue = rowView["Test"];
      CompareValidator cv1 = (CompareValidator)e.Row.FindControl("cv1); // checks between 2-7
      CompareValidator cv2 = (CompareValidator)e.Row.FindControl("cv2); // checks true/false
      cv1.Enabled = testValue.ToUpper().Equals("ABC");
      cv2.Enabled = !cv1.Enabled;
  }
}

you can do it by applying js on that gridview control on row data bound event
here is simple example

C#

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
TextBox tbx0 = (TextBox)e.Row.Cells[0].Controls[1];

tbx0.Attributes.Add("onblur", "return JSFunction(" + tbx0.ClientID + ");"

}
}

hi if it is dynamic gridview try this in edititem template.

case ListItemType.EditItem:

TextBox field_txtbox = new TextBox();
field_txtbox.ID = FieldName;
field_txtbox.Text = String.Empty;
field_txtbox.Width =60;
RequiredFieldValidator rfv = new RequiredFieldValidator();
rfv.ID = field_txtbox.ID + "valid";
rfv.ControlToValidate = field_txtbox.ID;
rfv.ErrorMessage = "Please Enter Value";
rfv.Display = ValidatorDisplay.Dynamic;
Container.Controls.Add(rfv);

Solution 4

You can add validators in item template and attach it to the control u want , validation will automatically take place on each row , if u want to do dserver side validation then custom validator,,, hope this works as a shortcut and better solution
