I'm wondering how is CommandArgument of a button passed to handler at low level.For example if I need to pass few values in CommandArgument what is better - to make it like 134_3554_345 and then parse or to pass an instanse of class like new MyClass(135,3554,345) ?
View 1 RepliesI have a table with 100 cells in it (10x10)
In each cell there is a checkbox. On page load, each checkbox is checked depending on records 0-99 from a database. This works fine.
However, I want to be able to update those 100 records in the database by checking or unchecking the checkboxes.
The update process works ok as I have debugged it, but the problem seems to be that if I check a checkbox, that value (true or false) doesn't get passed to the event handler.
This is the button click event handler that I'm running right now to see if the value is being recognised:
[Code]....
If I tick checkbox zero and click the button, it still comes up as false. What I want to happen is that the DB is updated and when the page loads, the checkboxes are repopulated with the new values from the database.
I need some high-level advice on how to deal with this issue. I want to have dynamically created buttons, each with a different CommandArgument, that call an OnCommand event when clicked. Given that these are dynamic buttons, I have to re-create them in Page_Load after the postback. However, when I re-create the buttons, the orginal command arguments are lost, and the arguments generated after the postback are only valid.As you'd expect, if I don't recreate the buttons, the event handler is never called because the buttons don't exist.My question is, how can I retrieve those original commandarguments, without the use of sessions.
View 6 RepliesI have a gridview with multiple rows, each has a Update button and I need to pass 2 values when someone clicks on Update button. Aside from packing the arguments inside CommandArgument separated by commas (archaic and not elegant), how would I pass more than one argument?
<asp:LinkButton ID="UpdateButton" runat="server" CommandName="UpdateRow" CommandArgument="arg_value" Text="Update and Insert" OnCommand="CommandButton_Click" ></asp:LinkButton>
As a note, the values can't be retrieved from any controls on the page, so don't offer any design solutions. Please concentrate on the question asked.
Is there a way of checking validation on the fly as the user inputs data and then when all validation is passed - change the submit button to green colour?

I have to handle error related to web application. I am not sure how its works. I am thinking that I will add an error page (error.aspx) and in global.asax ,application_onError, I will redirecting the user to error page and that should be enough ! i mean it will handle error automatically.

I made a dynamic TextBox and a Dynamic Button.. I would like to add an event on Dynamic Button to change the textbox text when clicked.

But when I click on the link button, it does a post back, but the Click Handler is not called? Also in the same page i have an asp:button, from javascript I am doing document.getElementByID('someid').click(), this also causes a postback but the button click handler on server is not invoked?
I'm trying to manually create a button and add a Click event handler for it in code. However when the button is clicked the event handler doesn't seem to react on event (or event isn't called).
we tested the code in Visual Studio 2008 and everything worked just as it should. And I'm using Visual Web Developer 2005 XE. So I assume that I'm missing something to be done manually being in VWD 2005 XE, or the problem is in VWD 2005 XE it self.
here is what I'm doing:

I put it down for a few weeks to work on other things, but started working on it again because I need to get it to work.
Anyway, I figured if I wanted to put a button in a datalist all I had to do was:
[Code]....
And then in code behind:
protected void datalist1_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName == "submit")
{
// code here
}
}
This is what everyone else says to do when I search google. I put a break on the event but the event never fires. Does it matter if I am using VS 2010 and .net 4.0?

For a given MS SQL Database table of staff members, I'm using ASP to display each record line by line as follows:
So I've added 2 ImageButtons in an extra column and the problem I have is passing the record id as a CommandArgument to redirect to a secure page where the record can be edited or deleted.
Here's some code:
[Code]....
[Code]....
ctdRdr(0) evaluates to the ID value for the the record. )
When I click on the 'Delete' ImageButton the URL in the Response.Redirect becomes:
ctdirectory_secure/deletemember.aspx?id=<%@%20ctdRdr(0)%>
instead of, say:
ctdirectory_secure/deletemember.aspx?id=435
I'm assuming that a <%= expression %> cannot be used to set a control parameter, but how else can I do it?
I have a ListView and I'm using the option <InsertItemTemplate>. Inside this template I have two control: TextBox and Button.
I'm having tourble in C# to read the CommandArgument of my button OnCommand event:

I have a button inside a table in gridview templatefield and i want to access its row index value in row_command event
i used this line.
Dim index As Integer = Convert.ToInt32(e.CommandArgument)

However i am able to fetch the row index value in button _click event using this line.
Dim index As Integer = (CType(CType(sender, Control).Parent.Parent, GridViewRow)).RowIndex
On a webform, I've got a Button inside a Placeholder control. Initiallty, I set its Click event declaratively in markup:
<asp:Button runat="server" ID="btnSubmitAgain" OnClick="btnSubmitAgain_Click" CssClass="button iconButton SubmitAgainbtn" />
However, everytime I click this button it bypasses the defined handler (the breakpoint I set is never hit) and behaves like a generic submit button and causes a postback. My handler clears a session variable and then Redirects back to itself so does not cause a postback).I've got an almost identical version of this form which behaves correctly and is, to all intents and purposes, identical code.
