如何以编程方式设置DataGridView单元的值？ [英] How to set value of a DataGridView Cell programatically?

问题描述

如果满足某些条件，我将尝试清除单元格。但是它不起作用。

I am trying to clear the cell if certain conditions are met. But its not working.

更新

 Private Sub DataGridView1_CellLeave(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellLeave
        Dim laspac As Int16 = DataGridView1.Columns("LASPAC").Index

        If e.ColumnIndex = laspac And DataGridView1.Rows(e.RowIndex).Cells("CType").Value.ToString.Trim() = "B" Then
            Dim B_LASPAC As DataGridViewCell = DataGridView1.Rows(e.RowIndex).Cells("LASPAC")
            Dim A_LASPAC As DataGridViewCell = DataGridView1.Rows(e.RowIndex - 1).Cells("LASPAC")
            If B_LASPAC.Value.ToString.Trim.Length <> 0 Then

                If Convert.ToDecimal(B_LASPAC.Value) + Convert.ToDecimal(A_LASPAC.Value) > 0 Then

                    B_LASPAC.Value = ""


                End If
            End If


        End If
    End Sub

推荐答案

非常简单，通过 RowIndex 和 ColumnIndex

例如。

Dim rowId = 0
Dim colId = 1

DataGridView1(colId, rowId).Value = "HELLO"

所以，在您的情况下...类似

so, in your case... something like

If ... Then
    DataGridView1(e.ColumnIndex, e.RowIndex).Value = ""
End If
