本文介绍了如何选择一个单元格的值?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有一个 DataGridView
,我想选择第一列的单元格。
Heres是我的 datagridview.Click
方法:
private void dataGridView1_CellClick(object sender,DataGridViewCellEventArgs e)
{
name = dataGridView1.CurrentRow.Cells [0] .Value.ToString();
}
目前我的名称变量是 null
。
我做错了什么?
解决方案
CurrentRow可能未设置但是,为事件参数使用RowIndex属性。尝试这样:
void dataGridView1_CellClick(object sender,DataGridViewCellEventArgs e){
if(e.RowIndex> -1&&&DataGridView1.Rows [e.RowIndex] .Cells [0] .Value!= null){
name = dataGridView1.Rows [e.RowIndex] .Cells [0] .Value.ToString( );
}
}
以防万一,确保事件有线up:
public Form1(){
InitializeComponent();
dataGridView1.CellClick + = dataGridView1_CellClick;
}
I have a DataGridView
, I want to select the cell of the first column.
Heres is my datagridview.Click
method:
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
name = dataGridView1.CurrentRow.Cells[0].Value.ToString();
}
Currently my name variable is null
.
What am I doing wrong?
解决方案
CurrentRow may not be set yet, so use the RowIndex property for the event argument. Try it this way:
void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e) {
if (e.RowIndex > -1 && dataGridView1.Rows[e.RowIndex].Cells[0].Value != null) {
name = dataGridView1.Rows[e.RowIndex].Cells[0].Value.ToString();
}
}
And just in case, make sure the event is wired up:
public Form1() {
InitializeComponent();
dataGridView1.CellClick += dataGridView1_CellClick;
}
