Can't update after clicking checkbox - ASP.NET Discussion Boards

Hi
Please specify your combobox's "Auto postback" property is true or not? if true u can write code in code behind otherwise u can do it from Javascript.

I Have another question is it ur control is combo or ListBox ? beacause listbox only have multi selection

Add this code on "Page Load"

DropDownList1.Attributes.Add("onchange","fnToolTip()");

----------------
Add this javascript code on HTML Code view

<script language="javascript" type="text/javascript">
function fnToolTip()
{
selIndex=document.getElementById("DropDownList1").selectedIndex
selValue=document.getElementById("DropDownList1").value
// alert(selValue)
document.getElementById("DropDownList1").title=selValue
}
</script>

-------------------

Add this code on Body

<asp:DropDownList ID="DropDownList1" runat="server" Width="185px">
<asp:ListItem Value="IM1">ITEM1</asp:ListItem>
<asp:ListItem Value="IM2">ITEM2</asp:ListItem>
<asp:ListItem Value="IM3">ITEM3</asp:ListItem>
<asp:ListItem Value="IM4">ITEM4</asp:ListItem>
</asp:DropDownList>
--------------------

Try this should work fine

I'm working with "CheckBox command in Repeater" found here:

I cannot find a way to update my database after checking the CheckBox. Which line is the culprit? What's missing?

MessageLabel.Text = "ItemID: " + chk.Text + " Checked: " + chk.Checked.ToString();

// HERE I CHANGE THE DEFAULT VALUE IN UPDATE PARAMETER OF THE CHECKBOX
AccessDataSource1.UpdateParameters[0].DefaultValue = chk.Checked.ToString();
// TESTER PLUTOT HARD CODED
AccessDataSource1.UpdateParameters[0].DefaultValue = "True";

// HERE I RESPONSE.WRITE JUST TO MAKE SURE MY UPDATE VALUE WAS PASSED
Response.Write("Passed Update parameter: " + AccessDataSource1.UpdateParameters[0].DefaultValue);

Hello all.

I have this ASP.NET webform which has many data input in order to create an appointment. This data is stored in our database. Yet the customer has asked if it is possible to send the appointment into Outlook/Exchange so that the customer can receive an email with the appointment. Is there any component (.NET, COM) or any way to do this?

Thanks in advance.

Hi Fernando,

I would use the information from the database to create a vCalendar file (you can Google vCalendar format to get the specifics on how to build the file) and then send that as an attachment to the user to import into their Calendar.

Hope this helps.

Thanks! I'll look for this vCalendar file thing.

hi everybody i have a problem with customising the javascript function for a validation control
i explain my pronlem with an exmple
i have two input on a table one is an email the other is the forename
a simple validation control for the email input is done
but when the email input is not empty i must
fill the forename input

so the html is like that

<asp:textbox id="forname" runat="server">
<asp:requiredfieldvalidator id="RequiredFieldValidator1" runat="server" errormessage="RequiredFieldValidator" ....="">

<asp:textbox id="email" runat="server">
<asp:regularexpressionvalidator id="RegularExpressionValidator1" runat="server" controltovalidate="email"
="" errormessage="please write a valid email!!" validationexpression="^\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,3}$">

how can i overwrite the validartor for the forname text to have a function in javascript that on submit event
do amessage error if the email is valid and the forname input is not filled
i explain when someone fill the email the forname must be filled and when the email is empty no control for the two input
thank you for help!!

You need to write some code that stores the client side Ids of the two controls as javascript strings, then you can use those names to write a custom validator that finds both controls and does the validation for you.

You may also be able to use two normal validators, and write a custom one that calls both and only sets the valid state to false if both of them fail.

thank you christian for you answer but i am a beginner in validation controls may be an example or a portion of code could help me thank you in advance for your answer Smile | :)

OK, I think there is actually a control on this site which validates multiple controls, I'd suggest looking for that

helo alll...,

this is my data:

my table is item(productid,stock) ,order(customerid,no_order), and orderdetail (no_order,productid,quantity)

example:

order and orderdetail displayed in gridview....

order is displayed like this:

--------customerid-------no_order

detail-------A---------------1

detail-------B---------------2

when i click detail in row 2, it's display orderdetail:

no_order_________productid_________quantity

____2________________c1________________2

____2________________p1________________3

i have make all this is ok. but i want to decrease stok in item with quantity in orderdetail.

my code in procedure like:

CREATE PROCEDURE [dbo].[order_item]
(

@productid AS varchar,
@quantity AS INT
)
AS
BEGIN
BEGIN TRANSACTION
DECLARE @no_order AS INT
DECLARE @stock AS INT

INSERT INTO [Orderdetail]
(

[ProductId],
[Quantity]
)
VALUES
(

@productId,
@quantity
)

SET @no_order = SCOPE_IDENTITY()
SET @Stock = (SELECT [Stock] FROM [item] WHERE [ProductId] = @productId)

UPDATE [item]
SET
[Stock] = @Stock - @quantity
WHERE
[ProductId] = @productId
COMMIT TRANSACTION
END
return

it can't work..

how about his true code in store procedure?

ok..., thx..

1 - use the right forum ( this is a SQL question )
2 - define 'it can't work', does it compile ? What does it return ?

Hello.

I have made a user information to store in session.

But when admin blocks the users, it shoud kill the users session if exsist.

I want to avoid using database.

You can't block the users session - the only way that you could do this would be to have some mechanism where the user queries to see if they still have access to things. You may be able to do this with the Cache if you want to avoid the database.

Deja View - the feeling that you've seen this post before.

Then only one think is could be done.... By checking every time post back, if user is valid.

Does server being overloaded if every post back is checked by using database?

Hello.

How can i make certan code piece to be executed only one at the time (Preventing to be executed if 2 diffrent users attempt to accsess same section)?

hi guys

i am having a asp.net application which is done in .net 2003 version, the problem here , i am having a text box with a range validator control for that.. when i changed controltovaliate property of the validator , the size of all the tables in the asp.net page is getting changed ,,such that the alignment is totally collapsed .. i have no idea how the sizes of tables (height and width of tables are dynamically changed)

regards

winnie

That's normal behaviour for tables. The size of the cells in a table are calculated from the size of the content in the cells. If you put something in a cell that is larger than the previously calculated size, the cell will grow and the other cells will be resized to give it space.
