使用c＃清除datagridview时，从datagridview中删除复选框列 [英] Remove check box column from datagridview when clear datagridview using c#

问题描述

我已经使用复选框列动态创建了datagridview，一旦刷新了我的datagrid，它将删除除复选框列之外的所有数据，下面的代码用于在datagrid中添加复选框列

i have created datagridview dynamically with check box column,once i refresh my datagrid its removes all data except checkbox column,below code for adding checkbox column in datagrid

DataGridViewCheckBoxColumn chk = new DataGridViewCheckBoxColumn();
dataGridView1.Columns.Add(chk);
chk.HeaderText = "Check Data";
chk.Name = "chk";
 int count = dataGridView1.Rows.Count;
 for (int i = 0; i < count; i++)
 {
     dataGridView1.Rows[i].Cells[12].Value = false;
 }

和以下用于清除我的数据网格的代码，如果我尝试在刷新后仍然在datagridview中添加新数据仍然存在旧复选框并且它继续添加一个复选框列。

and below code for clearing my datagrid,if i try to add new data in datagridview after refresh still old check box exists and it keeps adding one more checkbox column.

dataGridView1.Rows.Clear();
dataGridView1.Refresh();

任何建议???

any suggestion???

推荐答案

首先清除数据源，并清除绑定当您要清除时，数据源到网格视图。

Clear the data source first and , bind cleared data source to the grid view when you want to clear.

我尝试如下

i tried as follows

dataGridView1.Columns.RemoveAt(12);

i提到索引复选框和它的工作。



全部谢谢

i mentioned the index of checkbox and its worked.

Thanks All
