如何确定是正确的点击进行的ContextMenuStrip的dataGridView细胞？ [英] How to identify dataGridView cell that was right clicked on for ContextMenuStrip?

问题描述

用户权限点击一个DGV内的单元格，然后做了一个的ContextMenuStrip选择。根据他们的CMS的选择，我想要做的事（复制，隐藏，过滤器）。我的问题是标识是正确的点击单元格中。

我试图处理这种情况有以下方法，但[参数：columnIndex]不能被引用。

 私人无效cmsDataGridView_ItemClicked（对象发件人，ToolStripItemClickedEventArgs E）
 {
开关（e.ClickedItem.Text ）
 {
案复制：
中断; 
案过滤器的：
中断; 
案隐藏列：
 DataGridViewBand带= dataGridView1.Columns [e.ColumnIndex] 
 band.Visible = FALSE; 
中断; 
} 
} 
  

我应该在两种不同的方法这样做呢？一个处理鼠标点击（中，我可以再捕捉DGV列索引），然后从内部那里，我叫CMS项目点击事件？

感谢你的帮助，
布赖恩。

这为我的作品的代码。哦，我也必须从设计中的DataGridView的ContextMenuStrip属性中删除cmsDataGridView方法。 。离开，在那里引起的问题。

  //确定小区点击了cmsDataGridView 
的DataGridViewCell clickedCell; 
私人无效dataGridView1_CellMouseClick（对象发件人，DataGridViewCellMouseEventArgs E）
 {
试
 {
如果（e.Button == MouseButtons.Right）
 $ { b $ b dataGridView1.ClearSelection（）; 
 clickedCell = dataGridView1.Rows [e.RowIndex] .Cells [e.ColumnIndex] 
 clickedCell.Selected = TRUE; 
 cmsDataGridView.Show（dataGridView1，e.Location）; 
} 
 
} 
赶上（异常前）
 {
 Console.WriteLine（ex.Message + Environment.NewLine + ex.StackTrace）; 
} 
} 
 
私人无效cmsDataGridView_ItemClicked（对象发件人，ToolStripItemClickedEventArgs E）
 {
开关（e.ClickedItem.Text）
 { 
案复制：
中断; 
案过滤器的：
中断; 
案隐藏列：
 DataGridViewBand带= dataGridView1.Columns [clickedCell.ColumnIndex] 
 band.Visible = FALSE; 
中断; 
} 
} 
  

解决方案

您可以跟踪任何细胞最后点击通过添加在DataGridView的鼠标点击的事件处理程序。

是这样的：

 的DataGridViewCell clickedCell; 
 
私人无效dataGridView1_CellMouseClick_1（对象发件人，DataGridViewCellMouseEventArgs E）
 {
试
 {
 DataGridView的观点=（DataGridView中）发送; 
 
如果（e.Button == System.Windows.Forms.MouseButtons.Right&放大器;&安培; e.RowIndex> = 0）
 {
 Console.WriteLine（点击栏目
 + e.ColumnIndex +，行
 + e.RowIndex +的DataGridView的
 + view.Name +为
 + System.Windows。 Forms.Cursor.Position）; 
 
 clickedCell = view.Rows [e.RowIndex] .Cells [e.ColumnIndex] 
} 
} 
赶上（异常前）
 {
 Console.WriteLine（ex.Message + Environment.NewLine + ex.StackTrace）; 
} 
} 
  

然后在你的contextMenuStripItem点击事件，在clickedCell开关。像值：

 开关（clickedCell.Value）
 {
案复制：
断点; 
 ... //等
} 
  

User right clicks on a cell within a DGV, then makes a selection in the ContextMenuStrip. Based on their CMS selection, I want to do something (copy, hide, filter). My problem is identifying the cell that was right clicked on.

I was trying to handle this scenario with the following method, but [ColumnIndex] cannot be referenced.

private void cmsDataGridView_ItemClicked(object sender, ToolStripItemClickedEventArgs e)
    {
        switch (e.ClickedItem.Text)
        {
            case "Copy":
                break;
            case "Filter On":
                break;
            case "Hide Column":
                DataGridViewBand band = dataGridView1.Columns[e.ColumnIndex];
                band.Visible = false;
                break;
        }
    }

Should I be doing this in two different methods? One to handle the mouse click (in which I could then capture the DGV column index), then from within there, I call the CMS item clicked event?

Thank you for your help, Brian.

The code that works for me. Oh and I did have to remove the cmsDataGridView method from the ContextMenuStrip property of the dataGridView within the designer. Leaving that in there caused problems.

            // Identify the cell clicked for cmsDataGridView
    DataGridViewCell clickedCell;
    private void dataGridView1_CellMouseClick(object sender, DataGridViewCellMouseEventArgs e)
    {
        try
        {
            if (e.Button == MouseButtons.Right)
            {
                dataGridView1.ClearSelection();
                clickedCell = dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex];
                clickedCell.Selected = true;
                cmsDataGridView.Show(dataGridView1, e.Location);
            }

        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message + Environment.NewLine + ex.StackTrace);
        }
    }

    private void cmsDataGridView_ItemClicked(object sender, ToolStripItemClickedEventArgs e)
    {
        switch (e.ClickedItem.Text)
        {
            case "Copy":
                break;
            case "Filter On":
                break;
            case "Hide Column":
                DataGridViewBand band = dataGridView1.Columns[clickedCell.ColumnIndex];
                band.Visible = false;
                break;
        }
    }

解决方案

You could keep track of whichever cell was last clicked by adding an event handler for the DataGridView's mouse click.

Something like:

    DataGridViewCell clickedCell;

    private void dataGridView1_CellMouseClick_1(object sender, DataGridViewCellMouseEventArgs e)
{
        try
    {
        DataGridView view = (DataGridView)sender;

        if (e.Button == System.Windows.Forms.MouseButtons.Right && e.RowIndex >= 0)
        {
            Console.WriteLine("Clicked column " 
                       + e.ColumnIndex + ", row " 
                       + e.RowIndex + " of DataGridView " 
                       + view.Name + " at " 
                       + System.Windows.Forms.Cursor.Position);

           clickedCell = view.Rows[e.RowIndex].Cells[e.ColumnIndex];
        }
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message + Environment.NewLine + ex.StackTrace);
    }
}

Then in your contextMenuStripItem click event, switch on clickedCell.Value like:

switch (clickedCell.Value)
        {
            case "Copy":
            break;
... // etc.
}
