Hey
I have the following code
for (int x = 0; x < GridView4.Rows.Count; x++)
{
GridViewRow row = GridView4.Rows[x];
bool isCheckedIgnore = ((CheckBox)row.FindControl("chkIgnoreItem")).Checked;
if (isCheckedIgnore == true)
<b>now what it should do is perform an action when isCheckedComponentIgnore is false</b>
but it doesnt do that, the interesting thing is, is that the chkIgnoreitem is a column in a gridview which was ticked or unticked depending on a field in a database, I recently changed the field from format 1 or 0 to Y or N
does anyone know why this wouldn't work?
thanks!

Make the field in the database a bit-field
or
((CheckBox)row.Cells[x].Controls[0]).Checked
where x is the 0-based columnnumber

Yeah but I need to find all checkboxes which are ticked in order to perform the users request, a user can tick and untick a box
thanks anyway

if you lookad at you own code then you see your run a for-loop
place my code in your for loop!
|
|
|
|
|
bool isCheckedIgnore = ((CheckBox)row.FindControl("chkIgnoreItem")).Checked;
this will always return true coz u r by default giving value as checked
i think this is the reason for that if not please let me know

I can't change the field to bit, it needs to stay as nvarchar.
rajkumar.3 wrote: this will always return true coz u r by default giving value as checked
Im not sure on that because its finding the control and setting isCheckedIgnore to the result of that, therefore if the textbox is not ticked it should skip the first statement below and do the second
if (isCheckedComponentIgnore == true)
{
}
else
{
}

ok slightly seperate problem but related
ive got the following code which is binding data which is not a bit field but a varchar and contains Y or N in the column. The code below produces the error:
"Specified cast is not valid."
stringvalue = (bool)DataBinder.Eval(e.Row.DataItem, "fieldname");
however if I change the column to bit i.e. 1 and 0 it works.
Is there a way I can change the code so that it works without changing the column to 1 and 0 i.e. bit!
cheers

for (i=1;i=5;i++)
{
int a=i;
sqlinsert="update tbl_name set loop_no=a where rollnumber=a";
cmd = new SqlCommand(sqlinsert, conn);
try
{
cmd.ExecuteNonQuery();
}
catch(Exception ex)
{
FileStream fs;
StreamWriter sw;
fs=new Filestream("logfile.txt",FileMode.open);
sw=new StreamWriter(fs);
string newline="Roll No:"+a+"was not updated";
sw.close();
fs.close();
}
}
once if its go for "CATCH" block, how it can proceed others?
i.e, if record 2 fails, will it proceed other records and complete the whole FOR loop????
i tried.. but getting error...
how to achieve it?
thanks in advance and understanding....

Since this is not VB6 and you cannot Resume Next On Error, I guess you better validate what you're updating before trying to update it, and if it doesn't validate, not try to update. Simply. Thus, you get no exceptions and the for loops for as long as you want it to loop

The try/catch block is within the body of the loop. If an error occurs during one iteration of the loop, it will be caught and the code will proceed to subsequent iterations.

You need to post details of the error if you want help. We're not mindreaders.

Post details of your error, and maybe you'll get some help.

Please be more clear. I observe that variants of this question is scattered across the forum aplenty. Posting the same query multiple times actually dissuades focussed experts in helping out rendering your request futile.

Can you write your question in somewhat better manner. It is not at all clear what you want to ask.

 Buy a basic programming book, there are so much chaff in the above that it is impossible to guide you.
eg.
Convert.ToString(yearr.ToString()); <-- anything strike you as redundant in this snippet?

Your database administrator should really be kicked with a wet towel till he understands the folly he has created:
1) Allowing others to tamper the master database
2) Having a weak password for sa account.

Completely agree. Please, the English language has tools for letting people understand each other.
Anyhow, maybe you should consider changing the query and use the DB server date, something like SELECT * FROM tablename WHERE date = GETDATE() [if on SQL Server].

How do you expect the code to be executed if the website isn't running?
You do understand how websites, the internet and the HTTP protocol works, don't you?

No idea about what you really mean with 'not opening the website'  , but anyhow, in the code you posted before...
string month, yearr, datee, systemdate;
month = DateTime.Now.Month.ToString();
yearr = DateTime.Now.Year.ToString();
datee = DateTime.Now.Day.ToString();
systemdate = Convert.ToString(month.ToString()) + "/" + Convert.ToString(datee.ToString()) + "/" + Convert.ToString(yearr.ToString());
SqlConnection con = new SqlConnection("server=.;initial catalog=master;user id=sa;password=sa;");
con.Open();
SqlCommand cmd = new SqlCommand("delete from no where date='" + systemdate + "'", con);
cmd.ExecuteNonQuery();
con.Close()
What about...
SqlCommand cmd = new SqlCommand("delete from no where date= GETDATE()", con)
That's what I originally meant.

I would suggest you two things:
1) Prefer stored procedures instead of such queries.
2) Use Google first. These are little queries that Google can help you in a jiffy without having to wait for some one to respond and assist you through.
