javascript - 在 Gridview 中查找按钮并从代码隐藏中单击它(c#)

Question

我需要从代码隐藏中单击 GridView 内的按钮。我认为最好的方法是在代码隐藏中创建一个 javascript 函数，类似于我下面尝试的第二个解决方案。我将不胜感激任何帮助

    protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {

        if (e.CommandName == "Accepted")
        {

            int index = Convert.ToInt32(e.CommandArgument);

            GridViewRow row = GridView1.Rows[index];

       //find button

            Button btnEsc = (Button)row.FindControl("btnEsc");

       //here I would like to simulate a click on this button, so far no luck

        btnEsc.Click(); // this is wrong

         }
      }

我也尝试了这个，但它找不到按钮:我不知道如何在 gridview 中找到按钮

           System.Text.StringBuilder sbScript = new System.Text.StringBuilder("");
           sbScript.Append("document.getElementById('btnEsc').click();");
           ScriptManager.RegisterStartupScript(this, GetType(), "ClientScript", sbScript.ToString(), true);

当您打开灯箱时，将 Id 传递到隐藏字段。您可以稍后将其读出。此处的 ListView 示例。

protected void lvProjectServices_ItemCreated(object sender, ListViewItemEventArgs e)
    {

            if (e.Item.DataItem != null)
            {
                Whatever data = (Whatever)e.Item.DataItem;

                PlaceHolder objPlc3 = (PlaceHolder)e.Item.FindControl("phEdit");

                LinkButton link3 = new LinkButton();
                link3.Text = "<i class=\"table-edit\"></i>";
                link3.ID = "lbEditServer" + data.Id.ToString();
                link3.CommandName = "Edit";
                link3.CommandArgument = data.Id.ToString();
                link3.Click += link_Click;
                objPlc3.Controls.Add(link3);

            }
        }


    void link_Click(object sender, EventArgs e)
    {

        LinkButton btn = (LinkButton)sender;

        int Id = int.Parse(btn.CommandArgument.ToString());

        txtProjectServiceId.Value = Id.ToString();

            ScriptManager scriptManager = ScriptManager.GetCurrent(Page);

            if (!scriptManager.IsClientScriptBlockRegistered("openSvcModal"))
            {
                ScriptManager.RegisterStartupScript(Page, Page.GetType(), "openSvcModal", "$('select').select2(); $('#editProjectService').modal();", true);
            }
    }
