I am using asp.net 3.5 with c#. In my project i do some javascript
validation and some code in the button event to redirect the page to
another. But as i click the button it shows the javascript alert
message but at the same time it redirect to another page. I want to
verifying all the alert message and if there is no alert then it
redirect to the another page.
My javascript coding is
function Validate()
{
if(document.getElementById("<%=txtEmailid.ClientID
%>").value=="")
{
alert("EMAIL ID CAN NOT BE BLANK");
document.getElementById("<%=txtEmailid.ClientID%>").focus();
return false;
}
}
<asp:ImageButton ID="ImageButton2" runat="server" Height="28px"
ImageUrl="~/PHOTO/Continue.gif"
Width="121px"
onclick="ImageButton2_Click"
OnClientClick="return Validate()/>
At first i have tried the above to call the function in
OnclientClick . but as it not works so i did the follow
protected void Page_Load(object sender, EventArgs e)
{
ImageButton2.Attributes.Add("onclick", "return Validate()");
}
protected void ImageButton2_Click(object sender, ImageClickEventArgs
e)
{
some Sql queries and connection are here.............
try
{
conn.Open();
added = cmd.ExecuteNonQuery();
Session["userid"]=uniqueid.ToString();
Response.Redirect("HomePageComplete.aspx",true);
}
catch (Exception err)
{
lblCharMessage.Text = err.Message;
}
finally
{
cmd.Dispose();
conn.Close();
conn.Dispose();
}
}
but still i get the problem............pls guide me.....
