从C＃页面弹出警告消息

问题描述

我要显示一个弹出警报，当一些个行业已经得到NOT NULL值。我用code一块像下面，但没有工作correctly..Could你请让我知道corrcet语法做呢？

I need to show a pop up alert when some fileds have got not null values. I Used code piece like below , but not working correctly..Could you pls let me know the corrcet syntax for doing that?

    if (txtSearchName.Text != "" || cmbSearchOaO.SelectedItem.Text != "" || cmbVessel.SelectedItem.Text != "" || cmbSearchApplicationType.SelectedItem.Text != "" || cmbSearchHull.SelectedItem.Text != "" || cmbSearchCategory.SelectedItem.Text != "" || cmbSearchHazardCategory.SelectedItem.Text != "")
    {
        ScriptManager.RegisterClientScriptBlock(btApplySearch, btApplySearch, "<script> alert('Inserted successfully');</script>", true);
    }

下面btApplySearch是buttonID在ASPX标记使用。

Here btApplySearch is the buttonID used in aspx markup.

推荐答案

试试这个：

if (txtSearchName.Text != "" || cmbSearchOaO.SelectedItem.Text != "" || cmbVessel.SelectedItem.Text != "" || cmbSearchApplicationType.SelectedItem.Text != "" || cmbSearchHull.SelectedItem.Text != "" || cmbSearchCategory.SelectedItem.Text != "" || cmbSearchHazardCategory.SelectedItem.Text != "")
    {
         RegisterDOMReadyScript("alert message", "alert('Message Here');");
    }
