Hi
I have a radiobutton list, how do i specify in the c# to enable disbable one of the items in the list
thanks

<br />
private void DisableRadioButton()<br />
{<br />
RadioButtonToDisable.Enabled = false;<br />
}<br />
now that wasn't too hard was it? Of course, you can go wild and actually pass a reference to the particular radio button you want to disable and disable that one.

No your post disables the whole of the radiobuttonlist
I just want to disable one of the items in the list and I cannot find the correct syntax to do so
maybe you should read my original post again 
|
|
|
|

sorted it myself:
RadioButtonList_audit.Items[0].Enabled = true;
thanks for all your wisdom

Actually, it only disables one, the one named "RadioButtonToDisable".
As is, the addendum to the post says that you can expand on it where you can pass a parameter so you can choose which one you want to disable.
so something like this could exist:
enum eRadioButtonList
{
RadioButton1 = 1,
RadioButton2 = 2,
RadioButton3 = 3
}
private void DisableRadioButton(eRadioButtonList rbl)
{
switch(rbl)
{
case 1:
RadioButton1.Enabled = false;
Break;
case 2:
RadioButton2.Enabled = false;
Break;
case 3:
RadioButton3.Enabled = false;
Break;
}
}
There, did your homework

ok i think im misunderstanding you or vice-versa
i had:
<asp:radiobuttonlist id="RadioButtonList_audit" runat="server" visible="false">
<listitem text="Default Audit Settings" value="defaultAudit" enabled="true/">
<listitem text="Create Audit History With Reasons For Changes" value="detailedAudit" />
</listitem></asp:radiobuttonlist>
i wanted to disable listitem text"Create Audit History With Reasons For Changes" etc...
i did
RadioButtonList_audit.Items[1].Enabled = false;
it worked.. problem solved
hmm......

Just an aside, but you should probably access the items through Id rather than by index (ie, give each listitem an id attribute, and use RadioButtonList_audit.Items["someId"].Enabled). That way, if you add or reorder the options later on, your code won't break. Note that I did not test the above, but only present it as a logical solution. The actual syntax of using the id may vary.
Sounds like somebody's got a case of the Mondays

Hi! I need some help!!!
I have to store some datas(picture files)in the path and when harddisk is full i need to overwrite datas by replacing the old datas first!
How can i implement this program ??
thx

This automatically implies that you need some sort of mechanism that would maintain file creation order. My suggestion is that you ought to have a data table stored on a local database (SqlExpress is MORE than adequate) where you can retrieve the file names/paths in order and delete as necessary.

i am using ASP.net, C# anD SQL Server2005,in the following query:
string q = "SELECT collapsed_building.b_name,collapsed_building.b_desc FROM collapsed_building WHERE collapsed_building.b_name LIKE '" + crimewithdate.text2 + "' ";
I WANT TO USE % AFTER THE KEYWORD like SO THAT ALL THE BUILDING NAMES WHICH MATCH THE VALUE ENTERED BY THE USER ARE DISPLAYED
WHEN I WRITE (LIKE '" + %crimewithdate.text2 %+ "'), IT GIVES ERROR, WHAT WILL BE THE CORRECT SENTAX
|
|
|
|
|
(LIKE '%" + crimewithdate.text2 + "%')

I didnt encourage it, I simply corrected his mistake. Frankly if the OP has this wrong then he's going to be bafffled by terms that he doesnt understand.
Im 100% with you on the Sql Injection thing, but there is learning to walk before one can run.

I teach a basic C# training course. I actually threw out the materials I'd been given on the subject of databases and rewrote it. I ensure that at no time is anyone encouraged to inject values and I go directly to parameterised queries. So far with good results.
However, you might be right. If they already have the bad habit it might make it more difficult to break.

Im glad it worked. Now please heed the warnings below about Sql Injection attacks. IT IS IMPORTANT!

<br />
string qQuery = "SELECT b_name,b_desc" + <br />
" FROM collapsed_building" +<br />
" WHERE b_name = '" + crimewithdate.text2 + "' ";<br />
maybe u should ty = it always work
(just like an if)
p.s : yuo do not need to write "collapsed_building." as a prefix....

Please don't do this. You leave your code wide open to Sql Injection Attacks. Instead, consider using the techniques described here[^]. You'll end up a better developer for doing it.

A few things:
1) Please spell-check the post before you submit. A continuous broken language embarrasses the readers.
2) A continuos all-caps also indicates yelling at the users.
3) Technically, your query is vulnerable for SQL Injection attacks. You may need to review your SQL Querying patterns.
I would also advise you to have a read of Forum Posting Guidelines at http://www.codeproject.com/kb/scrapbook/forumguidelines.aspx [^]

You should be using parameters to pass filterable stuff to the query. Also, there is absolutely no validation on the Text value in crimewithdate
Where cmd is your SqlCommand object:
string value = string.Concat('%', crimewithdate.Text, '%');
cmd.CommandText = "SELECT b_name, b_desc "+
"FROM collapsed_building "+
"WHERE b_name LIKE @name";
cmd.Parameters.AddWithValue("@name", value);
Now, how big is your b_name column? Before you do anything with your query you should ensure that crimewithdate.Text does not exceed that size. Are there any other constraints? (e.g. only permitted to have alpha-numeric characters? Check for those also)

My 2 cents: you should never prepend with % or + in LIKE statement, it turns off indexes. It could hurt performance if you have lots of entries.
