Accessing public methods in User Controls?

Hi How can public methods in User Controls be accessed from a form's code behind. I have created a User Controls with a public accessor method:

// Public accessor to set/get the score so far 
public double Score
{
	get { return score;}
	set {  score = value; }
}

When I drag this User Control onto a Web Form I cannot seem to access the Score from my Web Form code behind.

Thanks.

there is no special work for it.
you can access to your user control id (such as usercontrol1) and use methods:
usercontrol1.score();

of course i test it on .net 2005 .
which .netframework you use?

How to use Contains() in an .ASPX page???

If you try to use Contains in an .ASPX page it will error the reason is the single quote you have to use.

So if you code "Select f1, f2, f3 from T1 where CONTAINS (F2, 'text*')" you will get an error at compile/run because of the single quote around your contains term. You cannot use the \ to escape the single quote either.

Does anyone know a way around this?

What do you mean? An apostrophe can be put in a string without problems.

Exactly what does your code look like, and what is the error message that you get?

OnRowCreated - Setting the properties of a column control

Hi. I have a GridView bound to a DataTable. The columns of the GridView are TemplateColumns with a TextBox in it.
The textbox columns appear with the values of the DataTable.

What I am trying to do is setting the TextBox to ReadOnly if certain conditions are met. I tried to do this within a handle to OnRowCreated (I get the created row in the eventargs e.Row). The problem is that I don't know how to get the TextBox object of a specific column in that row and set it's properties to ReadOnly.

Any help?
Thanks!

To get reference to the TextBox, you simply use the FindControl method in the event handler of the RowCreated event:

TextBox textBox = e.Row.FindControl('TextBoxId') as TextBox;

You now can set the ReadOnly property of the TextBox. However, you'd better use the RowDataBound event to set the ReadOnly property as the RowCreated event always happens, and you might not need that on postback. In addition, you can also use the databinding expression to set the ReadOnly property of the TextBox in the control declaration:

... ReadOnly='<%# ... %>' ...

Pressing F9 on a particular line of a method/event will set a break point. Once the breakpoint is reached you can then use F10 - Step Over and F11 - Step Into which ever you need.

You could use the below code.

<br />
System.IO.FileInfo oFile = new System.IO.FileInfo("c:\\Log.txt");<br />
long lSize = oFile.Length/1024;	<br />

It returns the file size as bytes. You can just divide 1024 to get the value in KB.

Display Date in a DropDownList

Hello

,

I m new to ASP.net and I am doing a project. In which when user selects Country(DropDownList) then only State(DropDownList)field should be enabled & only those states should be filled which belongs to selected Country.
I have created a table named State_City which contains two columns State and City. Record should come from table only.

plz help Confused | :confused:

as soon as possible.

Thanks & Regards,
Chandan Kumar

Here are the steps that you might need to do:
+ Set the AutoPostBack of the Country dropdownlist to true.
+ Create an event handler for the SelectedIndexChanged of the Country dropdownlist.
+ In the handler, get the selected value of the Country list.
+ Execute an SQL command to query states based on the specified country.
+ Bind the result to the State dropdownlist.

If you don't know to implement the steps, you can see ASP.NET quick start[^].

However, this way posts the entire page back the server, while you may want to update the dropdownlist only, so you can use AJAX here. The sample code is available out there, just have a good search.

Btw, the subject is asking about the Date, but don't see you mentioned it in your post.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
