I have a asp.net page where my button is enabled or disabled depending on whether two textboxes are properly filled out. I enable/disable the button through the onchange events of the textboxes. Once button is enabled and I click it, the postback seems to have disappeared because it does nothing.
I enable/disable the button like this:
function checkBuild() {
document.getElementById('sMsg').innerHTML = '';
checkBAL();
checkINI();
if ((checkBAL()) && (checkINI())) {
document.form1.btn1.disabled = false;
checkWarning();
} else {
document.form1.btn1.disabled = true;
}
}
I've read that in order for the button "btn1" to postback, I must have it enabled onLoad which I have done for testing. Therefore, if I click the button before my javascript fires, it works; only stops working once my checkBuild() function is called by the textboxes javascript onchange event. Can anyone help with this issue? Many thanks.

Call the javascript function on the bottom of the page.

I have asked this question in the SQL message board but am unsure if that would be the right place.
The problem is that im using an accordion which houses a bunch of textboxes. Now I have a SQLDATASOURCE that I bind to those textboxes (which are in about 4 different panes). I can choose the textboxes from the list, I can type the textboxes in the codebehind and everything. You know when you use stuff like LoginView you have to use the FindControl.
Now when I perform the insert command it says it can't find the first one (txtDescription) and stops. So I said ok, lets put the SQLDATASOURCE i nthe same pane with txtDescription. Works! Then it can't find the first textbox in the next pane!
How would I get around this? I love the way (and everyone else that has seen it) I made it with the accordion.

I'm trying to create a dynamic URL in a report viewer, but I am having a tough time at it. What I need to do is have a link "View" that has a URL of http://server/path to page/View.aspx?ReportNumber=.
I need to pass the Number column's value for the navigation of the link. I can get it to the point where I can use a static URL, but not dynamic. Any pointers?

There are about 10 pages in my project which are used to populate reference tables and each page needs to have text boxes to input data and format (i.e. number of text boxes, format of data etc) So I want to make a user control for data entry and place in all pages so that I dont have repeat the same code. But I not very comfortable with events and delegates and also passing data to and from a user control and webpage. Can someone suggest me code or some links which help me in doing this.
Thanks

Any book on ASP.Net 2.0 should have examples of this.
I would also suggest that you are making things more difficult than need be. What is wrong with having 10 pages to update 10 tables? That seems like good design to me. Putting code to update 10 tables in one user control seems like a terrible idea. Why take something simple and make it complex like that?
Think about this. If you don't touch this application for a couple years and you have to modify one of these reference tables. If you have one page per table, think how easy it will be to maintain! If you have some fancy trickery to put all the code in one user control think about how much more difficult it will be to dive back into the code. Just my two cents...

No no I am not trying to put whole code to update 10 tables in same user control's code. Since the html part is same in all the pages I thought of having it in a user control and have a save button on it. When user clicks save then I thought of handling that event on the web page to save the data. Not sure if this is the right way.I am new to .Net It is really simple when I have the html part on all pages but I want have it in one place and reuse it.

Sorry I misunderstood. Here are some tips for you. Create a public property for any control in your user control that you want to use in the page. And vice versa. Most books will give you an example of using userControl.FindControl("id"). But I find it cleaner and easier if just create a public property.
As for events... In the page_init of the page containing the control is where you set the event. Here is a quick example...
Good luck.
<br />
public partial class WebUserControl : System.Web.UI.UserControl<br />
{<br />
public Button submitButton<br />
{<br />
get { return this.Button1; }<br />
set { this.Button1 = value; }<br />
}<br />
protected void Page_Load(object sender, EventArgs e)<br />
{<br />
<br />
}<br />
<br />
protected void Button1_Click(object sender, EventArgs e)<br />
{<br />
<br />
}<br />
}<br />
<br />
<br />
public partial class _Default : System.Web.UI.Page <br />
{<br />
protected void Page_Init(object sender, EventArgs e)<br />
{<br />
this.WebUserControl1.submitButton.Click += new EventHandler(submitButton_Click);<br />
}<br />
protected void Page_Load(object sender, EventArgs e)<br />
{<br />
<br />
}<br />
<br />
protected void submitButton_Click(object sender, EventArgs e)<br />
{<br />
Response.Write("event handled");<br />
}<br />
}<br />
<br />

Todd thanks for your response I could access my the controls on a user control this way. Can we also access if the user control is on a master page?

When I run a website project within the ID, I get the "Connection Interrupted" message. What am I doing wrong?
[EDIT] It's a two-part problem. I'm using Firefox 3 as the "browse with" setting in the IDE. Firefox is changing the host name from "localhost" to "www.localhost.com", and the VS2008 IDE is decrementing the actual port number by two before running the browser.
So, I get this:
http://www.localhost.com:49230/Default.aspx
instead of this:
http://localhost:49232/Default.aspx
I also tried it with the both the internal browser and IE7, and while the host name issue is gone, the port is STILL wrong.

I had the same issue. Do you have Nod32 anti-virus installed? Are you using Vista? If yes, problem is with protocol filtering. If you can, stop the anitivirus program. Or you can configure Nod32, so that it won't do this.

Hi all. I've got a web applicaiton here that I'm developing against IE6 (it's for a company intranet, and they're still all on IE6...)  The bug I'm noticing is this - If I select any single-line text box, and enter enough text so that the length of the text exceeds the length of the text box, the textbox pushes over to the left when I tab away from the textbox, or click away from it. The funny thing is that it's not resizing or anything to display the text therein, instead it's pushing over to the left by the distance that the text exceeds its length, staying the same sixe, and the text in the textbox remains shoved over to the left in the textbox, so that the last character is visible but the first one is not. Has anybody else come across this?

Hello all,
I am getting the following error:
The connection name 'MyConnection' was not found in the applications configuration or the connection string is empty. Although I have specified the connection string properly in my web.config file.
It was working earlier. What might be the problem?
Thanks.

hi
i've got a gridview on a parent webform. after closing a child form that was opened in modal mode i want the gridview to be refreshed. now i have tried several things that dont work and i dont know why:
1. tried to use: __doPostBack(buttonName,'') in javascript methode but nothing happened.
this is the code i have used:
code behind:
protected void Page_Load(object sender, EventArgs e)
{
if (IsPostBack)
return;
btnNewChore.OnClientClick = "javascript:OpenChild( theURLOfTheChildForm, btnRefresh.ID)";
}
protected void btnRefresh_Click(object sender, EventArgs e)
{
gridViewChores.DataBind();
}
Javascript:
function OpenChild(theURLOfTheChildForm,targetButton)
{
var winSettings = "center:yes;resizable:no;dialogHeight:300px"
var returnValue = window.showModalDialog(URL, "", winSettings );
if (returnValue == null)
{
window.alert("NO chore was created!");
}
else
{
__doPostBack(btnName,'');
}
2.i've also tried to use
document.all("btnRefresh").click();
instead of __doPostBack but i've got an error :document.all("... not an object etc...
Thank you in advance for your help

I had this same problem. I never found a solution, I ended up using window.redirect('samePage.aspx');
I had used the code in the modal window to save the parameters in session state. Then when the parent page reloaded it used the new parameters to bind the grid.

Is the other page that's being opened an aspx page? If it is, you can try declaring an object type of formview in the popups code behind. For ex. FormView fv = new FormView();
fv = (FormView)this.Parent.FindControl("NameOfFormView");
fv.DataBind();
However, I used AJAX's modalpopupextender on an ascx User Control that was on my page, so I hope it will work for you too.
There is a possibility Parent may need to be in there more than once depending upon the levels.

Hi All,
I need to read image from the bitmap. I don't want to save it on to the server, but read directly from object in order to display it in image object . My code is:
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
Stream stream = response.GetResponseStream();
MemoryStream ms = new MemoryStream();
BinaryWriter bw = new BinaryWriter(ms);
BinaryReader br = new BinaryReader(stream);
bw.Write(br.ReadBytes((int)response.ContentLength));
ms.Position = 0;
Bitmap fred = Bitmap.FromStream(ms) as Bitmap;
Now Please give me a solution to read the image from this bitmap.
