Before saving the record,I will be checking if that record exist in the database or not(in the code behind).If it exist,then I need to show an alert to the user as "Record already exist.Do you want to proceed?"When the user press 'Yes',I need to continue my save for the record in the code ,else I just need to exit the save process.

//......code for checking the existence of the record    
if (check == true)
{            
    ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "script", " confirm('Record already exist.Do you want to proceed?');", true);

推荐答案

您可以使用确认框在JS这样

You can use confirm box in JS like this

var ans = confirm ('Record already exist.Do you want to proceed?');
if(ans==true)
{
}
else
{
}

其次，要获取code反应的背后，你可以存储是/否值转换成一个隐藏字段例如

Secondly, to get the response in code behind, you can store the Yes/No value into a hidden field e.g.

document.getElementById('<%= hiddenField.ClientID %>').value = ans;
