1、你首先建立一个DataRow对象，把数据添加到该对象中。DataGrid.Rows.Add方法可以增加新行。
2、
String aa="12345a";
try
{
Console.WriteLine(Convert.ToInt32(aa));
}
catch(Exception ex)
{
Console.Write("格式不正确");
}

5.12 How can I restrict the keystrokes that will be accepted in a column of my datagrid?

You can create a custom column style and handle the KeyPress event of its TextBox member. Below is the code showing how this might be done. You can also download a sample project (C#, VB) that shows an implementation of this idea.

public class DataGridDigitsTextBoxColumn : DataGridTextBoxColumn

{

public DataGridDigitsTextBoxColumn(System.ComponentModel.PropertyDescriptor pd, string format, bool b)

: base(pd, format, b)

{

this.TextBox.KeyPress += new System.Windows.Forms.KeyPressEventHandler(HandleKeyPress);

}



private void HandleKeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)

{

//ignore if not digit or control key

if(!char.IsDigit(e.KeyChar) && !char.IsControl(e.KeyChar))

e.Handled = true;



//ignore if more than 3 digits

if(this.TextBox.Text.Length >= 3 && !char.IsControl(e.KeyChar))

e.Handled = true;

}



protected override void Dispose(bool disposing)

{

if(disposing)

this.TextBox.KeyPress -= new System.Windows.Forms.KeyPressEventHandler(HandleKeyPress);



base.Dispose(disposing);

}

}

5.16 How can I do cell by cell validation in a datagrid?

There are problems trying to implement cell by cell validation using the grid's Validating event architecture. The problem is that the grid is not the object handling the data. Instead, a TextBox or some other control is the control managing the changing of the cell contents. One way to implement the validation at the grid level is to handle the CurrentCellChanged event, and if the previous cell's value is not proper, then return to that cell. You can download a sample that implements this process. The sample only handles the validation from cell to cell movement. If you want to handle the validation when the user clicks on the forms Close button, then you would have to add a special event handler for this and do one last validation at this point.

DataGrid.Rows.Add就可以了

[冷月孤峰]

很简单的，看一下代码就会了
DataRow a=dataSet31.Tables["表名"].NewRow();
a[0]=textBox1.Text;
a[1]=textBox2.Text;
a[2]=comboBox1.Text;
a[3]=textBox3.Text;
a[4]=dateTimePicker1.Text;
a[5]=dateTimePicker2.Text;
a[7]=comboBox2.Text;
a[6]=dateTimePicker3.Text;
a[8]=textBox4.Text;
a[9]=textBox5.Text;
a[10]=textBox6.Text;

dataSet31.Tables["表名"].Rows.Add(a);

sqlDataAdapter1.Update(dataSet31,"表名");

直接修改dataset。

[kuangren]

用Table.Rows.Add()就可以了～
