Does anyone check the domain of an email address as part of their verification steps? eg. Confirm that gmail.com exists if the user specified blah@gmail.com as their address.
I should note that in my webapp an existing user can forward invites to their friends. I have no need to verify those invites at all. Rather, I just want to warn my user if a typo etc. may be sending an invite to the wrong person. Is this even worthwhile to do?
How do I check if a value in the dropdownlist is in the table bound to the girdview?
Some fields bound to the gridview contain values that are not in the dropdownlist. I would like to check in the code behind whether the value is there and if not set the ddl selected value to "Select" with a value of "". If the value is there then set the selectedvalue to the value in the gridvidew.
Also, the ddl is nested inside an edit template.
Here's an example:
<form id="form1" runat="server">
<div>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="Logs_ID"[code]....
In my application Im saving multiple files(image,pdf,txt) to a folder. Suppose I have an image with name "image1", if this image already exists in the folder and if another user tries to add another image with the same name "image1" then, it should give message to change the File name.
I had used below code:
string filePath = DamRep_FileUpload.PostedFile.FileName;
string filename = Path.GetFileName(filePath);
string contenttype = String.Empty;
if (contenttype != String.Empty)
{
if (File.Exists("~/FTP/File/"))
[Code] ....
but its not working.
This is my aspx code :
<asp:Chart ID="ChartAlertes" runat="server" Width="500px">
<Titles>
<asp:Title Text="Nombre d'alertes et leurs status en fonction des filtres renseignés"
BorderColor="Black" Alignment="TopCenter">
</asp:Title>
</Titles>
[code]...
I display 2 Points (2 columns) in the Chart Control and I change the color of the each Points with :
ChartAlertes.Series[0].Points[0].Color = System. Drawing. Color.Red;ChartAlertes.Series[0].Points[1].Color = System.Drawing.Color.DarkOrange;
But sometimes, I have only 1 Point to display or nothing at all on the Chart. So I'd like to check If there are some Points before to put the color of each Point.
For example :
if (ChartAlertes.Series[0].Empty == false)
{
//...
}
