[英]c# how to get data out of datagrid by buttonclick from button in datagrid?
[英]How to get a cell value buttonclick in DataGrid C#
当我单击button
时,我想在ShowRichMessageBox
的一行中显示特定的单元格值,但是如果单击该行的任何位置,此事件将显示该单元格值。
这里有什么问题.....我该如何解决以上问题???
我有一些大的对数值,但已经在单元格中加载了,所以, Is it possible to expand the row when i select a particular row in the datagridview???

public LogView()
{
InitializeComponent();
this.dataGridView2.CellClick += new System.Windows.Forms.DataGridViewCellEventHandler(this.dataGridView2_buttonCol);
bindingList = new SortedBindingList<ILogItemView>();
dataGridView2.DataSource = bindingList;
this.dataGridView2.SelectionMode = DataGridViewSelectionMode.FullRowSelect;
this.dataGridView2.MultiSelect = false;
var buttonCol = new DataGridViewButtonColumn(); // The button to display a particular cell value when clicks//
buttonCol.Name = "ButtonColumnName";
buttonCol.HeaderText = "Show";
buttonCol.Text = "View";
buttonCol.UseColumnTextForButtonValue = true;
dataGridView2.Columns.Add(buttonCol);
}
private void dataGridView2_buttonCol(object sender, DataGridViewCellEventArgs e)
{
string name = Convert.ToString(dataGridView2.SelectedRows[0].Cells[2].Value);
ShowRichMessageBox("Code", name);
}
编辑:
if (e.ColumnIndex != 0) // Change to the index of your button column
{
return;
}
if (e.RowIndex > -1)
{
string name = Convert.ToString(dataGridView2.Rows[e.RowIndex].Cells[2].Value);
ShowRichMessageBox("Code", name);
}
传递给CellClick事件处理程序的DataGridViewCellEventArgs实例具有ColumnIndex属性,您可以检查该属性以查看单击是否来自按钮列。
像这样:
private void dgv_buttonCol(object sender, DataGridViewCellEventArgs e)
{
if (e.ColumnIndex != 4) // Change to the index of your button column
{
return;
}
if (e.RowIndex > -1)
{
string name = Convert.ToString(dgv.Rows[e.RowIndex].Cells[2].Value);
ShowRichMessageBox("Code", name);
}
}
对于您问题的第二部分,我不确定您的意思,但是您可以更改行高,也许可以在SelectionChanged事件中使用它,或者如果您想做更深入的操作,请参阅“如何:自定义外观Windows Forms DataGridView控件中的行数”
