[英]How to get the text from current cell in datagridview textchanged event?
i am making a windows form application in which i used a datagridview.我正在制作一个 Windows 窗体应用程序,其中使用了 datagridview。 i want that when i write something in textbox in datagridview,than a messagebox appears containing the string i wrote.. ican't get my text in textchanged event..我希望当我在 datagridview 的文本框中写一些东西时,会出现一个包含我写的字符串的消息框..我无法在 textchanged 事件中获取我的文本..
all thing must be fired in textchanged event.. here is my code:-所有的事情都必须在 textchanged 事件中触发..这是我的代码:-
void dataGridView1_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e)
{
if (dataGridView1.CurrentCell.ColumnIndex == 1)
{
TextBox tb = (TextBox)e.Control;
tb.TextChanged += new EventHandler(tb_TextChanged);
}
}
void tb_TextChanged(object sender, EventArgs e)
{
//listBox1.Visible = true;
//string firstChar = "";
//this.listBox1.Items.Clear();
//if (dataGridView1.CurrentCell.ColumnIndex == 1)
{
string str = dataGridView1.CurrentRow.Cells["Column2"].Value.ToString();
if (str != "")
{
MessageBox.Show(str);
}
}
void tb_TextChanged(object sender, EventArgs e)
{
var enteredText = (sender as TextBox).Text
...
}
Showing MessageBox
in TextChanged
will be very annoying.在TextChanged
显示MessageBox
会很烦人。
Instead you could try it in DataGridView.CellValidated event which is fired after validation of the cell is completed.相反,您可以在完成单元格验证后触发的DataGridView.CellValidated事件中尝试它。
Sample code:示例代码:
dataGridView1.CellValidated += new DataGridViewCellEventHandler(dataGridView1_CellValidated);
void dataGridView1_CellValidated(object sender, DataGridViewCellEventArgs e)
{
if (dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value != null)
{
MessageBox.Show(dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString());
}
}
