On the page load there will be gridview with a default row....there is a button with a + sign at the bottom...on the button click i want to create a new rows in the grid..before that i need to make sure that all fields have values.But I am getting null values..

My code is:

            TextBox age_value = ((TextBox)Gridview1.Rows[0].FindControl("TextBox2"));
            DropDownList sex_value = ((DropDownList)Gridview1.Rows[0].FindControl("DropDownList1"));
            DropDownList berth_value = ((DropDownList)Gridview1.Rows[0].FindControl("DropDownList2"));

Any help will be appreciated.

请将此代码写在代码Gridview1.EditIndex-1末尾，不确定EditIndex或Edititemindex，请尝试使用它可能会对您有所帮助。

Try using a condition

if(name_value.Text!="" && age_value.Text && sex_value.Text && berth_value.Text)
{

//action
