Pop UP alert message from c# page

Question

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);
    }

Here btApplySearch is the buttonID used in aspx markup.

Try this:

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');"); 
    }

Hope Its Helpful.

if not using Update panel then use below code

Page.ClientScript.RegisterStartupScript(this.GetType(),"Msg",alert("Javascript message"), true);

else

ScriptManager.RegisterStartupScript(this.GetType(),"Msg",alert("Javascript message"), true);

try the following code inside the if :

if (txtSearchName.Text != "" || cmbSearchOaO.SelectedItem.Text != "" || cmbVessel.SelectedItem.Text != "" || cmbSearchApplicationType.SelectedItem.Text != "" || cmbSearchHull.SelectedItem.Text != "" || cmbSearchCategory.SelectedItem.Text != "" || cmbSearchHazardCategory.SelectedItem.Text != "")
{
    ScriptManager.RegisterStartupScript(this, this.GetType(), "err", "alert('Message you want write');", true);
}

RegisterStartupScript has 5 parameters we used. this :: referers to the control, this.GetType() is used to get the type of control, err is a string key. alert('mesage') whatever you want to write, true :: do you want to add script block in code or not if yes the true otherwise false

Hope this will work for you
