如何在winform中子窗体提交数据后刷新父窗体中的DataGRIDVIEW数据?

[photojjc]

我在子窗体写了

private void Btc_Click(object sender, EventArgs e)
        {
            this.DialogResult = DialogResult.OK;
            this.Close();
        }

在父窗体写

 private void OrgDgv_RowHeaderMouseDoubleClick(object sender, DataGridViewCellMouseEventArgs e)
        {

                PerInfoForm PerInfoForm = new PerInfoForm();
                
                if (OrgDgv.SelectedRows.Count != 0)
                {
                    string ryid = OrgDgv.SelectedRows[0].Cells[0].Value.ToString();
                    string jgid = OrgDgv.SelectedRows[0].Cells[1].Value.ToString();
                    PerInfoForm.setryid(ryid,jgid,"2");
                    PerInfoForm.ShowDialog();
                    if (PerInfoForm.ShowDialog() == DialogResult.OK)
                    {
                        string sqlstr = "select *  from PER_INFO where ORG_ID like '" + tvorg.SelectedNode.Tag.ToString() + "%'";
                        tmpdt = Getdt(sqlstr);
                        navigator1.DataBanding();
                        jgid = tvorg.SelectedNode.Tag.ToString();
                        PerInfoForm.setjgid(jgid, "1");

                    }
                    PerInfoForm.Dispose();
                }
                else
                {
                    return;
                }


        }

那为什么我要点两次退出才能关闭子窗口呢？
这段话不该写在这吗？

if (PerInfoForm.ShowDialog() == DialogResult.OK)
                    {
                        string sqlstr = "select *  from PER_INFO where ORG_ID like '" + tvorg.SelectedNode.Tag.ToString() + "%'";
                        tmpdt = Getdt(sqlstr);
                        navigator1.DataBanding();
                        jgid = tvorg.SelectedNode.Tag.ToString();
                        PerInfoForm.setjgid(jgid, "1");

                    }

[回忆是抓不到的月光]

刷新的问题，在父窗口写一个public函数刷新DGV的数据，然后传递父窗口对象引用到子窗口实例中，至于怎么传，你可以通过构造函数或者父窗口调用子窗口对象某个函数传递都可以，然后再子窗口对应事件函数中处理调用父窗口对象的刷新GDV函数，完毕

重新查询

[houyizhinv]

private void OrgDgv_RowHeaderMouseDoubleClick(object sender, DataGridViewCellMouseEventArgs e)
        {

                PerInfoForm PerInfoForm = new PerInfoForm();
                
                if (OrgDgv.SelectedRows.Count != 0)
                {
                    string ryid = OrgDgv.SelectedRows[0].Cells[0].Value.ToString();
                    string jgid = OrgDgv.SelectedRows[0].Cells[1].Value.ToString();
                    PerInfoForm.setryid(ryid,jgid,"2");
                    //PerInfoForm.ShowDialog();                    if (PerInfoForm.ShowDialog() == DialogResult.OK)
                    {
                        string sqlstr = "select *  from PER_INFO where ORG_ID like '" + tvorg.SelectedNode.Tag.ToString() + "%'";
                        tmpdt = Getdt(sqlstr);
                        navigator1.DataBanding();
                        jgid = tvorg.SelectedNode.Tag.ToString();
                        PerInfoForm.setjgid(jgid, "1");

                    }
                    PerInfoForm.Dispose();
                }
                else
                {
                    return;
                }


        }

试试

[houyizhinv]

private void OrgDgv_RowHeaderMouseDoubleClick(object sender, DataGridViewCellMouseEventArgs e)
        {

                PerInfoForm PerInfoForm = new PerInfoForm();
                
                if (OrgDgv.SelectedRows.Count != 0)
                {
                    string ryid = OrgDgv.SelectedRows[0].Cells[0].Value.ToString();
                    string jgid = OrgDgv.SelectedRows[0].Cells[1].Value.ToString();
                    PerInfoForm.setryid(ryid,jgid,"2");
                    //PerInfoForm.ShowDialog();
                    if (PerInfoForm.ShowDialog() == DialogResult.OK)
                    {
                        string sqlstr = "select *  from PER_INFO where ORG_ID like '" + tvorg.SelectedNode.Tag.ToString() + "%'";
                        tmpdt = Getdt(sqlstr);
                        navigator1.DataBanding();
                        jgid = tvorg.SelectedNode.Tag.ToString();
                        PerInfoForm.setjgid(jgid, "1");

                    }
                    PerInfoForm.Dispose();
                }
                else
                {
                    return;
                }


        }

好多问这个问题的啊，解决办法也好多，就这2天都有3个问这个问题的帖子了。
委托，传窗体，还有设置子窗体属性判断刷新。。。

                {

                    PerInfoForm.setryid(ryid,jgid,"2");
                    DialogResult dResult = PerInfoForm.ShowDialog();

                }


        }

PerInfoForm.ShowDialog();
if (PerInfoForm.ShowDialog() == DialogResult.OK)
-------------------------------------------
调用了两次

[zzyhuian06142]

第一次
PerInfoForm.ShowDialog();
第二次
PerInfoForm.ShowDialog() == DialogResult.OK

到最后都没看到刷新父窗体中的DataGRIDVIEW数据的代码。。。
