有谁能解决让winform的datagrid响应row的单击事件和双击事件

[wfhlxl]

就是说单击某个单元格，让datagrid感知单元格所在行被单击了，调用 用户能在其中写处理代码的事件函数，而实际上datagrid要做这样的事真是力不从心，microsoft是怎么想的呀。

参考这个网址。

实现这个功能没有什么问题啊

[tonysunny]

你可以到datagrid 的属性框里面添加事件啊

[wfhlxl]

DataGrid 不能响应单击和双击事件呀 ,不信,你们试试

[anycool]

private void dataGrid1_Click(object sender, System.EventArgs e)
{
if(ds!=null)
{
if((MessageBox.Show("确定要删除此记录吗?","删除记录操作",MessageBoxButtons.YesNo))==DialogResult.Yes)
{
using(SqlConnection conn=new SqlConnection("server=.;uid=sa;pwd=ok;database=musicmanagment"))
{
string sql=" delete musicTable where Musicid="+ds.Tables[0].
Rows[this.BindingContext[ds.Tables[0]].Position][0];
ds.Tables[0].Rows[this.BindingContext[ds.Tables[0]].Position].Delete();
SqlCommand com=new SqlCommand(sql,conn);
conn.Open();
int i=com.ExecuteNonQuery();
conn.Close();
this.dataGrid1.DataSource=ds.Tables[0];
if(i>0)
{
MessageBox.Show("删除成功!");
}
}
}
}

}

这样可以写出在datagrid中的单击事件,确定删除的行数

不知是不是这个呢~~

上面只是一个例子.

这个是可以实现的，我给你一个我的代码:
private void SetUp()
{
string select="SELECT SUP_NO, COMPANY_NAME, ADDRESS FROM t_b_SUPPLIER WHERE STATUS!=9 ORDER BY SUP_NO ASC";
SqlDataAdapter da = new SqlDataAdapter(select,conn);
DataSet ds=new DataSet();
da.Fill(ds,"t_b_SUPPLIER");
dataGrid1.SetDataBinding(ds,"t_b_SUPPLIER");
}


private void AddCustomDataTableStyle()
{


DataGridTableStyle ts1 = new DataGridTableStyle();
ts1.MappingName = "t_b_SUPPLIER";
// 设置属性
ts1.AlternatingBackColor = Color.LightGray;


// 添加Textbox列样式，以便我们捕捉鼠标事件
DataGridTextBoxColumn TextCol = new DataGridTextBoxColumn();
TextCol.MappingName = "SUP_NO";
TextCol.HeaderText = "供应商编号";
TextCol.Width = 100;
TextCol.ReadOnly = true;
//添加事件处理器
TextCol.TextBox.Click += new EventHandler(TextBoxDoubleClickHandler);
ts1.GridColumnStyles.Add(TextCol);


TextCol = new DataGridTextBoxColumn();
TextCol.MappingName = "COMPANY_NAME";
TextCol.HeaderText = "供应商名称";
TextCol.Width = 150;
TextCol.ReadOnly = true;
TextCol.TextBox.Click += new EventHandler(TextBoxDoubleClickHandler);
ts1.GridColumnStyles.Add(TextCol);


TextCol = new DataGridTextBoxColumn();
TextCol.MappingName = "ADDRESS";
TextCol.HeaderText = "供应商地址";
TextCol.Width = 200;
TextCol.ReadOnly = true;
TextCol.TextBox.Click += new EventHandler(TextBoxDoubleClickHandler);
ts1.GridColumnStyles.Add(TextCol);

ts1.SelectionBackColor = System.Drawing.Color.Blue;

dataGrid1.TableStyles.Add(ts1);



}
private void dataGrid1_CurrentCellChanged(object sender,System.EventArgs e)
{
dataGrid1.Select(this.dataGrid1.CurrentCell.RowNumber);
}

private void TextBoxDoubleClickHandler(object sender, EventArgs e)
{
SUP_NO = this.dataGrid1[this.dataGrid1.CurrentCell.RowNumber,0].ToString();
contract_sp_new myForm = new contract_sp_new();
myForm.ShowDialog();
}

忘了补充了：
在FormLoad中要加上 AddCustomDataTableStyle()；

试试，单击完全可以。
另外，这个方法只适用于单击。如果双击，我看可以参考楼上的！

[wcmj]

dataGrid1_Click是能响应的,但是在某此情况时会取到错的单元格,不知道算不算dataGrid
的bug

[wcmj]

建议你用muoseclick做,我现在在做的项目就是用这个解决的

[wcmj]

调用 用户能在其中写处理代码的事件函数，而实际上datagrid要做这样的事真是力不从心，microsoft是怎么想的呀。

我晕,你不会用就不要乱说!

你在属性里加事件就行了, 不会加事件吗? 点属性里的闪电符号后,想要哪个加哪个
要是这个也不知道的话那没办法了

[wfhlxl]

楼上的几位,你们究竟试过没有,真的能让DataGrid当单元格被单击时候,DataGrid能捕捉到事件,就是说你的DataGrid的Click事件函数没被调用,不信,你们试试.

[wfhlxl]

怎么没人理解我说的呀,DataGrid 不能响应单击和双击事件呀
