推荐答案

//you can do as below

protected void gridview_RowDataBound(object sender, GridViewRowEventArgs e)
             {
                 if (e.Row.RowType == DataControlRowType.DataRow)
                {
                    CheckBox chk = (CheckBox)e.Row.FindControl("chktest");
                    chk.Checked = false;
                }
             }

如果找到的内容标记为解决方案

mark as solution if its what you are finding

在 row_databound 事件中，您需要使用 findcontrol()方法搜索gridviewrow中的复选框然后取消选中它们.
或者，您可以使用以下代码.

In row_databound event you need to use findcontrol() method to search checkboxes in gridviewrow and then uncheck them.
OR you can use following code.

(row.Cells[CheckBoxColumn.Index] as DataGridViewCheckBoxCell).value = false;

您将复选框列绑定到什么值?

如果是布尔值，请确保在数据源中将所有值都设置为false.

如果未绑定任何值，请确保已在复选框标记中设置了Checked="False".

HTH！

如果这可以解决您的问题，请标记为解决方案！

What value are you binding the checkbox column to??

If it is a bool then ensure that all values are set to false in the data source.

If you are not binding any value then ensure that you have set the Checked="False" in the checkboxes markup.

HTH!
