选定的datagridview行错误 [英] Selected datagridview row eror

问题描述

你好，

我有这个小问题.

我有datagridview，在CellClick事件上我有此代码.

Hello,

I have this little problem.

I have datagridview and on CellClick event I have this code.

dg.Rows[e.RowIndex].Selected = true;

我使用此事件在任何单元格上单击时都选择行，但是现在我单击列标题对列进行排序时出现了问题.

我收到此错误.

I use this event to select row on click on any cell, but now here comes the problem when I click on the Header of column to sort the column, I cant.

I get this error.

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

任何人?在此先感谢您.

Anyone? Thanks in advance.

推荐答案

u可以检查CellClick事件中的标题行，而无需处理标题行.标题行的索引为-1.所以试试这个:

u can check for Header row in CellClick event and dont process for header row. Header row has index -1. so try this:

private void gv_CellClick(object sender, DataGridViewCellEventArgs e)
{
    if (e.RowIndex != -1)
    {
        //Your code
    }
}

我将代码更改为此

dg.CurrentRow.Selected = true;

现在可以使用了，但仍然在CellClick事件上，如果不应该在CellClick事件上，也许需要做一些不同的事情

I changed code to this

dg.CurrentRow.Selected = true;

now it works, but still its on CellClick event, maybe something different has to be done if it should not be on CellClick event

单元格单击事件不好，您尝试使用Gridview RowCommand事件会更好

Hi,

Cell click event is not good, you try to use Gridview RowCommand event is to be better
