Hi All,
I have an ASP.Net applicaiton in which I am using Entity Framework, I have a table (table1) which is referencing two of its columns from two different tables (table2 and table3). When I am trying to load table1 from entity frame work its not loading the values of table2 and table3. I know I have to put include in Linq statement but I am not sure how to handle for the two foreign keys. How can I put the Linq to handle two foreign keys.
Is there any separate way to get handle two Foreign Keys the Entity Framework.
Please help me in accomplishing this task, its an urgent requirement.
Thanks in advance.

Not an include, but a JOIN statement[^].

Mostly, you cannot group them as each edit will have their own logic and queries. If you can try to make it close to generic if you have a similar structure.

No need to provide two separate links. Single link 'View', on click of which you need to launch the file with Process.Start, it will automatically prompt a dialog asking to Open or Save it. User can do whatever they want.
Process.Start("filePath with name");
P.S.: Next time avoid making the whole question bold.

No. No one will provide full code to you.
You need to try by yourself. Try out and post specific issues if you face any.

I would like to share sample program regarding files clean up on Browser close button.
1.Include below script
<script type="text/javascript">
$(document).ready(function () {
$(window).unload(function () {
if (event.clientY < 0) {
$.ajax({
type: "POST",
url: "Default.aspx/Cleandir",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: true
});
}
});
});
</script>
2. In code behind, create method using [WebMethod]attribute.
[WebMethod]
public static void Cleandir()
{
try
{
DirectoryInfo dirinfor = new DirectoryInfo(@"C:\Users\Desktop\image");
if (dirinfor.Exists)
{
FileInfo[] filename = dirinfor.GetFiles();
if(filename!= null)
{
if (!(filename.Length.Equals(0)))
{
foreach(FileInfo f in filename )
{
File.Delete(f.FullName);
}
}
}
}
}
catch (Exception ex)
{ }
}
}
Basically web method is being called using Ajax in jquery when user clicks on Browser close button.
Thanks,

I'm looking for some kind of best practice fot imersonate users to one ASP.NET site that I build.
The user handling of the site is entirely own built with a "User" table in the database and so on. The "Password"-column is crypted.
Now I want to build a simple and SAFE solution for our support personal so they from our Support site can click on a button and a session is started in the customer portal. That so he support person more easily can log in as he was the customer user and se the same thing as the customer do.
Any tip on how to solve this is welcomed. Now I think about creating a GUID and send that in querystring that is pased to the customer portal. The GUID can be used for a short period.

Wrong forum! You should have posted in C# forum[^]
For now, to stop click of image, you can make it readonly/disabled?

Hi
In my page i have 4 text boxes which are associated with ajax calender.user can enter the date or can select from the calender.Currently I have put 4 custom validator to validate the user input and I have associated a jave script function onclientfunction of the validators to check the date format. My idea is that if i put only one custom validator and can check for all the different inputs to validate the date. is it possible?
my java sript function takes two parameters (source, args).If it is possible please send me the sample code.
In custom validator there is one attribute which says the control to validate?Now for each control i have to put a validator. I want one validator to check for all the text input.Is it possible. I am new to ASP programing.So please give the sample code. I want like if i exit the text box or click on the save button this should work.And this should be done in client side not in the server.
Thanks
Prashant

i want to set a value of label using javascript and that value will from asp.net codebehind...
codebehind code:
vimage.Attributes.Add("OnMouseOver", "divimgcomments('" + divcmdstext + "');");
javascript code:
function divimgcomments(imgcmds) {
//alert(imgcmds);
var _vlblmoimgcmnds = window.document.getElementById("<%=lblmoimgcmnds.ClientID%>");
_vlblmoimgcmnds.value = imgcmds;
divimgcomments1();
}
|
|
|
|
|
Not too clear on what is the issue and what you seek!
Try:
vimage.Attributes.Add("OnMouseOver", "divimgcomments('" + divcmdstext + "');");
function divimgcomments(imgcmds) {
var _vlblmoimgcmnds = window.document.getElementById("<%=lblmoimgcmnds.ClientID%>");
_vlblmoimgcmnds.InnerHTML = imgcmds;
}
