When you click on Hyperlink then save the value in session,
On page load event get that value from the session, If session is not null then execute the database command for retrive the data and show it on page.

Hi All,

How to create a report builder for end user in web application. The end user can be able to construct query at run time like they can choose table and fields, can give aggregate functions and filter conditions etc. After this, the end user can able to create report using some tool like our RS2000/2005 report builder. When I was checked with report server-report builder, the client system needs to have MS Visual studio IDE. Can any one came around any tool for this?

Thanks in advace.

A Hard question.

I Have page in aspx, but in different page i would not to redirect, but to read entire content in html format into string?

It is like Response.Redirect, it executes, and convert to html then redirect. But i want to do exactly same, expect redirect, but to string.

I want to do this, because that html would be sent as an email.

Thanks you in advance.

If you need to grab the HTML source that is returned from a web page, then you use the WebRequest[^] Class to request the page and that will return a WebResponse[^]

WebRequest request = WebRequest.Create("http://www.tempuri.org");
WebResponse response = request.GetResponse();
Stream responseStream = response.GetResponseStream();
//Do whatever you need to with the stream, create your email, whatever.
response.Close();

Get the Data into a DataSet and then use multiple GridView's that use Data Filters to filter the data needed.

Hi,

I'm using window.showModalDialog to open a modal dialog.
The modal dialog needs get the current user's name. To do this i use
Membership.GetUser().UserName;
But when the dialog is posted back Membership.GetUser() return null
and i can't get the user's name.

Does anybody have a clue how to get the user's name?

Thanks.

Unable to re-enable a radio button if disabled server-side

WSonck17-Sep-07 6:55

Hello,

I'm having some problems to enable radiobutton in ie7 by javascript. I was googling all day, but I only found one post with the same problem I have. I paste it here to explain what my problem is:

Hi All,

I've come across the problem of not being able to re-enable a radio
button with javascript if its initial state has been disabled in the
Page_Load() method of the code behind.

Might i add that it behaves fine in Firefox, but IE is unable to
re-enable the radio button. IE is fine if the radio button starts in an
enabled state.

Version of IE i'm using is 6, and i have also tried with IE7 and got
the same result.

Is this a bug specific to IE ?

This post has only one answer, which is:

Hi There

function enable()
{
var controls = document.getElementsByTagName("input");
NumElements = controls.length;

for (i=0;i<NumElements;i++)
{
if(controls[i].name=="rdEnable")
{
controls[i].setAttribute("disabled" , false);
ParentSpanControl = controls[i].parentElement;
ParentSpanControl.setAttribute("disabled" , false); break;
}
}

return false;
}

Explanation:
============
A DotNet Radio Button Control will result in creation of the following
three controls

1.Span Control
2.Input Type=Radio
3.Label

So using javascript , do identify all the controls that radio button is
rendered to and set their disabled propery to false;

Please find the above code which does the same

I tried to enable by javascript the input (this works in Firefox, Opera and Netscape, but not in IE), the span, and the label, but I have not get the solution. Here I put the code I try with:

function habilitarPr2IDI(){<br />
<br />
var controls = document.getElementsByTagName("input");<br />
NumElements = controls.length;<br />
<br />
for (i=0;i<NumElements;i++)<br />
{<br />
if(controls[i].name=="InputName")<br />
{<br />
controls[i].disabled = false;<br />
ParentSpanControl = controls[i].parentNode;<br />
label = ParentSpanControl.lastChild;<br />
ParentSpanControl.disabled = false;<br />
label.disabled = false;<br />
}<br />
}<br />
}

Can anyone help me? Thanks a lot.

Check the HTML source of the page rendered when the radio buttons are disabled. My guess is that the radio buttons aren't rendered with just a disabled atteribute but in another way all together for IE. I've never actually looked at it myself, but it's the first guess in my head.

Re: Unable to re-enable a radio button if disabled server-side

WSonck17-Sep-07 21:01

This is the HTML source of a disabled radio button:

<td><span disabled="disabled"><input id="radioId" type="radio" name="radioName" value="Text" disabled="disabled" /><label for="radioId">Text</label></span></td>

and this is the HTML of a non-disabled radio button:

<td><input id="radioId" type="radio" name="radioName" value="Text" /><label for="radioId">Text</label></td>

I think the problem is in the tag span. I try to disabled the span too, but didn´t work in IE.

Menu control flyouts don't appear where the should

eggsovereasy17-Sep-07 6:12

17-Sep-07 6:12

I recently rolled out a change where I changed the old javascript menu (that only worked in IE) to a new menu using the ASP.NET menu control (so it works in other browsers). I have one user with Windows XP and IE6 where the flyouts on the menu appear at the top of the page rather than next to the menu control like it does on every other computer/browser combination I tested on (and that other users are using). I installed all the patches for IE6 from windows update, but I can't move to IE7 since the company has other internal apps that don't work on IE7. This same computer can do another application I built with the ASP.net menu control perfectly.

Any idea why this happens? I might just go with a pure CSS menu, but its hard to beat the simplicity of the menu control.

e.Keys.Count , e.NewValues,e.OldValues, even e.RowIndex everything returns 0.
What I want to do is, store the grid in the dataset and then when the row is edited,

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e) is called.

now after all rows are updated, the updated grid will be stored in the dataset and finally everything will be pushed into db on Save button click.

Can you please help me how to do this?
