Anthem.Net[^] is one of the best AJAX framework I can find for .Net.
Since it can do postback through XmlHttpRequest (where you don't need to refresh the page) I hope it can solve your problem.
You can use it just like normal ASP.Net controls.

PopUp problem

Hi!

I have a page (say parent page) which has a button(Button1). When the user clicks on 'Button1', a popup screen(child page1) pops up. This child page has a lot of controls. When the user clicks on one of the buttons on this child page , the childpage1 closes and the values entered in child page are displayed on the parentpage controls. I have implemented this using showModalDialog() , __doPostBack() (for the button Button1) and Page.GetPostBackEventReference(Button1 ,string.Empty).

The part mentioned above is working absolutely fine.

Now, on the same parent page, I have one more button (Button2), which when clicked also opens another pop up page(child page2). In this child page2, I have drop downlist & listbox. The dropdownlist has autopostback (= true) which fills up the listbox.

My problem is that, it doesn't fill up the listbox. I have run the debugger within the code-behind , and found that , the items get filled in the listbox but it never shows on the screen.

I have implemented this page also with the above mentioned method. I don't understand what the reason is.

Can anybody please suggest.

Thanks and regards,

WSE authenticated web service

I created a .net web service which uses WSE 2.0 for authentication, this works great and the app has been in production for almost a year now. The problem is we have a client that wants to consume the service using Delphi 7.0 and isn't able to pass the authentication. If you have worked with Delphi consuming a WSE authenticated web service I would appreciate any insight you can provide to resolve this.
Thank you,

Postback question

I have an application where the user can enter new part numbers. I have a datagrid. They push a button to insert a new line. Since I am adding a new row to the dataset, I have to first initialize the dataset, table, etc.

Where I am running into problems is when the user enters more than one blank line. I can add the first one no problem. But if I want to insert a second blank line, the page always postsback and just resets that first line.

Is there a way to say, "For the first row, initialize everything, but for the second row and beyond, stay on the same page!"

One solution is to disable the insert new button once the new row has been created. How are you binding the data to the grid? Are you doing so at design time, do it from the code behind instead and then you can bind the data whenever you want.

how vital enterprise application are for proactive organizations leveraging collective synergy to think outside the box and formulate their key objectives into a win-win game plan with a quality-driven approach that focuses on empowering key players to drive-up their core competencies and increase expectations with an all-around initiative to drive up the bottom-line. But of course, that's all a "high level" overview of things

I got it to the point that I get my new blank lines to appear. However, I have the problem that if I enter data in line one, hit add line, and add a second line. It resets the first line--the data is lost. I tried setting session variables but still not working. This is the code for the add button:

private void Button2_Click(object sender, System.EventArgs e)<br />
		{	<br />
<br />
			DataGridItemCollection items = dgParts.Items;<br />
			int rows = items.Count;<br />
			if (rows == 0)<br />
			{<br />
		<br />
				BindData();<br />
				DataTable dt = ds.Tables["Rest"];<br />
				DataRow row;<br />
				row = dt.NewRow();<br />
				strPartNumberInputReference = txtSearchPart.Text;<br />
				row["PartNumber"] = strPartNumberInputReference; <br />
				row["DrawingNumber"]=DBNull.Value;<br />
				row["DrawingRevision"]=DBNull.Value;<br />
				row["DwgPath"]=DBNull.Value;<br />
<br />
				dt.Rows.Add(row);			<br />
				dt.AcceptChanges();	<br />
			<br />
				dgParts.DataSource=dt;			<br />
				dgParts.DataBind();<br />
				Session["test"]=ds;<br />
			}<br />
<br />
			else<br />
			{<br />
				ds = (DataSet)Session["test"];<br />
				DataTable dt = ds.Tables[0];<br />
				DataRow row;<br />
				row = dt.NewRow();	<br />
				strPartNumberInputReference = txtSearchPart.Text;<br />
				row["PartNumber"] = strPartNumberInputReference; <br />
				row["DrawingNumber"]=DBNull.Value;<br />
				row["DrawingRevision"]=DBNull.Value;<br />
				row["DwgPath"]=DBNull.Value;<br />
				dt.Rows.Add(row);			<br />
				dt.AcceptChanges();			  <br />
				dgParts.DataSource=dt;			<br />
				dgParts.DataBind();<br />
			}<br />
<br />
		}

Any ideas? Thanks for your help!

what do you mean by read?
To load into a byte array you can do the following.
byte[] newFile = System.IO.File.ReadAllBytes(@"\YourFile.tif");

Hi, I am using C#.NET to create an instance of MS Access 2003. I try to open my Access Report, but the Application just hangs as soon as I get to the part where I open my Database.
Here is part of my code:
oAccess = new Access.ApplicationClass(); //No problem
if(!oAccess.Visible) oAccess.Visible = true; //No problem
sDBPath = "C:\\Reporting.mdb";
oAccess.OpenCurrentDatabase(sDBPath,false, ""); //PROBLEM IT HANGS!!!
// Preview the report:
oAccess.DoCmd.OpenReport(sReport,Access.AcView.acViewPreview, moMissing, moMissing, Access.AcWindowMode.acWindowNormal, moMissing)
My problem is that it stops on the line that attempts to open the DB AND DOES NOT CONTINUE FURTHER.Ohh by the way I wrote the same code in VB6 and it worked just fine.Please help.
