从呼叫GridView的RowDeleting事件JavaScript函数 [英] Call Javascript function from Gridview RowDeleting event

问题描述

我需要从if条件调用JavaScript警报在gvLocations_RowDeleting部分的GridView中。

I need to call a javascript alert from an if condition inside a gridview in the gvLocations_RowDeleting section.

code是如下：

protected void gvLocations_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
    if (CheckIfLocationExists(ID) == true)
    {
        //need to call javascript function sendmessage() here?? 
    }
}

我在.aspx文件中的JavaScript函数如下：

I have a javascript function in the .aspx file as follows

<script type="text/javascript">
function sendmessage()
{
    alert("Area is associated with this location already");
}
</script>

我知道这是一个简单的举动，但出于某种原因，有麻烦林。有人能帮忙吗？提前致谢。堆栈溢出石头！

I know this is an easy move but for some reason Im having trouble. Can someone help? thanks in advance. Stack Overflow rocks!

Actually I figured it out. Hopefully this will help someone else..Use the code below, works like a charm..

Page.ClientScript.RegisterStartupScript(this.GetType(), "helloworldpopup", "alert('hello world');", true);
