[英]Find Button inside a Gridview and click it from codebehind(c#)
我需要從背后的代碼中單擊位於gridview內的按鈕。 我認為最好的方法是在后台代碼中創建javascript函數，類似於我在下面嘗試的第二種解決方案。 我將不勝感激
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
}
}
我也嘗試這樣做，但是找不到按鈕：我不知道如何在gridview中找到按鈕
System.Text.StringBuilder sbScript = new System.Text.StringBuilder("");
sbScript.Append("document.getElementById('btnEsc').click();");
ScriptManager.RegisterStartupScript(this, GetType(), "ClientScript", sbScript.ToString(), true);
當您打開燈箱時，請將ID傳遞給隱藏的字段。 然后，您可以稍后閱讀。 這里是ListView的示例。
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(); $('#editProjectService').modal();", true);
}
}
后面的代碼：
public partial class WebForm1 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
btn.Text = "Refreshed";
if (Request.Params["btnPressed"] != null && Request.Params["btnPressed"] == "true")
{
ScriptManager.RegisterStartupScript(Page, typeof(Page), "OpenWindow", string.Format("$('#{0}').click()", btn.ClientID), true);
}
}
protected void btn_Click(object sender, EventArgs e)
{
btn.Text = "Not Refreshed";
lbl.Text = "Not Refreshed";
System.Threading.Thread.Sleep(1000);
////to refresh the page
Page.Response.Redirect(HttpContext.Current.Request.Url.ToString()+"?btnPressed=true", true);
}
}
在aspx頁面中加載jquery：
<body>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<form id="form1" runat="server">
<div>
<asp:Button runat="server" ID="btn" OnClick="btn_Click" PostBackUrl="/WebForm1.aspx" />
<asp:Label runat="server" ID="lbl"> </asp:Label>
</div>
</form>
</body>
您應該真正學習jquery，它是一個很棒的工具。 克/升。
