Hello everyone,
I am using loadcontrol method to load custom controls.
I have a single .aspx page and a left menu (.ascx control) which is loaded dynamically.
When i click on the left menu's link, control is loaded accordingly.
The problem is:
Loadcontrol always loads control with ispostback=true.
It happens bcoz i have used __doPostBack() onclick of the leftmenu's link.
I want the ispostback = false in the control's load event.
Any help is always welcome.
Thanks,
Malay Khandhediya.

I have two Dropdownlists inside a GridView within the EditItemTemplate. I would like to know how to catch the event of the SelectedIndexChanged. I'm trying to Populate the second DropdownLists when the first one has been selected. Problem is the SelectedIndexChanged Event is not being called inside the EditItemTemplate.
Any Ideas would be greatfull.

Try using the Header Template for the headers where you can customize the view of the headers.
Or if you have the data come from different data source and one is depenedent on the other try using a repeater for the main data then a grid view for each repeated item. But I am not sure this is your case.

need regular expression for alphanumeric string having space, if any one can help
|
|
|
|
|
|
Why the apostrophes? An alphanumeric string should not contains apostrophes, should it?
[\da-zA-Z ]
Despite everything, the person most likely to be fooling you next is yourself.

You could try something like this:
string query = "SELECT Image FROM TAB_Employee WHERE EmpID='" + EmpID + "'";
SqlCommand cmdImg = new SqlCommand(query, gCnn);
byte[] image = (byte[])cmdImg.ExecuteScalar();
MemoryStream mstream = new MemoryStream(image);
Bitmap bitmap = new Bitmap(System.Drawing.Image.FromStream(mstream));
Response.ContentType = "image/gif";
bitmap.Save(Response.OutputStream, System.Drawing.Imaging.ImageFormat.Gif);
bitmap.Dispose();
Best of luck

Ok what i think you need to do is:
Place the connection code in a new WebForm and then on the page that your showing your image set the image ImageUrl property to the new webform.
E.g.
Image.aspx is the new webform
Image.aspx contains the new code listed in the post above.
WebForm1.aspx is the page with your image
Set the ImageUrl property to the new webform.
Image.ImageUrl = "Image.aspx";
When the ImageUrl try to load it will load the new Image.aspx page.
Since you are changing the ContentType it should load the page as an Image.
Let me know if this works for you, if not i'm sure there are a ton of different ways to make this work for you.
Best of luck!!!

Hi,
I have ReportViewer Control in Asp.Net page that access one SSRS report from report server "XXX".
I configured report path and report url and its working fine in local machine.
But its giving Access Denied Error when we try to access the page from other machines as follows:
"The request failed with HTTP status 401: Access Denied."
Scenario:
We deployed the ASP.Net application in machine "A", accessing the application from machine "B". And the SSRS report is deployed in Report server machine "C". When we open the application in machine A itself all are working fine.
But when we access the application from machine "B", We are able to access the application except the report in the application.
Any ideas to get rid of this error?
Thanks in Advance

You might need to look at Kerberos delegation - you are authenticating yourself with the machine at A, but it needs to be able to bounce your authentication on to the machine at C. If you look at the logs on C, you'll probably find access denied for the network user.

The stuff on w3schools is all going to be as good as it gets, if you don't understand it, perhaps you need a book ?

You can apply a javascript function which returns bool on clientclick of the controls.In that function you can validate the value if its true the it goes to server else you cal show show message and ask to rewrite again.
as
<asp:textbox id="txtServiceNo" runat="server" width="170px" onkeypress="javascript:return Validateit()" xmlns:asp="#unknown">
Cheers!!

AspDotNetUser wrote: this work is totally in html not in asp.net
Then why are you posting in this ASP.NET forum instead of the web developemnt one?
There is no end of JavaScript tutorials and examples on the web - just search around til you find some you like. Another good way of learning is to view the source code of web-pages that do the sort of thing you want to achieve.
Study and then come back with any specific questions - but do not expect people here to provide you with fully functional code.
Do your best...

Use document.getElementByID('The name of your control').value
