问题描述

我有一个

DataGridview有

四个Coloumns

SlNo InvoiceNo应付税款



am在按钮上以编程方式添加行单击

然后设置EditonEnter模式。

在列表上逐个填充列

和textChanged税栏中的事件

获取应付款栏上的值

等于金额税。



但问题是在textThanged事件中Tax

应付款单元格未获得所需的值。

在输入之后支付单元格然后在选项卡上

获得价值。



如何解决此问题我希望在文本更改或当我更改

税单位值应付款单元格必须获取金额单元格的值 - 税单位。

请协助。我已经将税单元素转换为文本框。

and then have set EditonEnter mode.
Filling the Columns one by one on tab
and on textChanged Event of "Tax" column
getting the Values on Payable Column

ok i got It working
Declared at top

Dim WithEvents txt1 As TextBox

将列投射到文本框

Cast the column to Textbox

Private Sub dgvInvoice_EditingControlShowing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles dgvInvoice.EditingControlShowing
        Try

            If dgvInvoice.CurrentCell.ColumnIndex = 3 Then
                If TypeOf e.Control Is TextBox Then
                    txt1 = DirectCast(e.Control, TextBox)
                End If
            End If
            

        Catch ex As Exception
            MsgBox(ex.Message)
        End Try
    End Sub

并最终提高了textchanged事件

and Finally Raised the textchanged Event

Public Sub txt1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txt1.TextChanged

       
            If dgvInvoice.CurrentCell.ColumnIndex = 3 Then
                --- DONE WHAT I WANTED
            End If

    End Sub

在顶部声明

Declare at top

TextBox txt1;

将列投射到文本框

Cast the column to Textbox

private void dgvInvoice_EditingControlShowing(System.Object sender, System.Windows.Forms.DataGridViewEditingControlShowingEventArgs e)
{
	try {

		if (dgvInvoice.CurrentCell.ColumnIndex == 3) {
			if (e.Control is TextBox) {
				txt1 = (TextBox)e.Control;
			}
		}


	} catch (Exception ex) {
		MsgBox(ex.Message);
	}
}

和最后提出了textchanged事件

and Finally Raised the textchanged Event

public void txt1_TextChanged(System.Object sender, System.EventArgs e)
{

	if (dgvInvoice.CurrentCell.ColumnIndex == 3)
	 {
		----DO what you want
	}

}
