Okay.Delete button is in the repater.right?then in the delete button click event you'll get the item index and using that item index delete that object from the viewstate and rebind repeater.is that makes sense?

Which values you are loosing?ItemIndex is enough to delete it from ViewState?Is this code working?whats the difficulty you are facing in the above code?
If you are saying about entered values in textboxes, then save that values to the persisting object before rebinding the repeater.

the last row is deleting if i click on delete of any row... what may be problem

You might have 'hard coded' index of last row. Please check that. This could be the case.

hi sashidhar.....
i tried to use the update panel.....i took an update panel.....and 5 buttons....took a session variable and incremented it on click event of each button.....it all worked but the problem now is if i refresh the page the value of session variable is not refreshed....counting starts from the last where the page was refreshed....i'm providing you the code....Have a look....!!!
The default.aspx File:
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<br />
<asp:Button ID="Button6" runat="server" onclick="Button6_Click" Text="cancel" />
<br />
<br />
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<br />
<br />
<br />
<asp:Label ID="Label1" runat="server" Text="Panel Created"></asp:Label>
<br />
<br />
<br />
<asp:Button ID="Button1" runat="server" BackColor="Aqua"
onclick="Button1_Click" Text="Button" />
<br />
<br />
<asp:Button ID="Button2" runat="server" BackColor="Aqua"
onclick="Button2_Click" Text="Button" />
<br />
<br />
<asp:Button ID="Button3" runat="server" BackColor="Aqua"
onclick="Button3_Click" Text="Button" />
<br />
<br />
<asp:Button ID="Button4" runat="server" BackColor="Aqua"
onclick="Button4_Click" Text="Button" />
<br />
<br />
<asp:Button ID="Button5" runat="server" BackColor="Aqua"
onclick="Button5_Click" Text="Button" />
</ContentTemplate>
</asp:UpdatePanel>
</div>
</form>
</body>
now the Default.aspx.cs File:
The code was given on click event of all buttons taken in update panel:
int i = Convert.ToInt32(Session["i"]);
i++;
Session["i"] = i.ToString();
Button3.BackColor = System.Drawing.Color.Red;
Label1.Text = "Refreshed at " + DateTime.Now.ToString();
Button3.Enabled = false;

Will there be any problem for image to display in runtime? If IIS is not installed in our system?
Every time in run time the image in not viewable but while at design time it is viewable.
|

1. Displaying images does not depens upon IIS. If you dont have IIS then you can not host an .NET web application.
2. It seems that you can run the application and in runtime you can not see images. FYI, you mention images path in controls of your application and at runtime, the images path should match to the actual physical location images.
if you dont see images, rather you get to see 'image' control but a 'cross' showing images not displayed, right click on images to get to see what path the control is expecting at runtime. Depending upon that you should modify the image path in design view.
Please let me know if you get it going.
Thanks,

Hi I've a problem with the property .SelectedText.
I've Microsoft Visual Web Developer Express 2008 - Framework version: 3.5.
The problem is that Visual Studio can not find this property, I also checked that there were any dll.
Property. SelectedText is in the System.Windows.Controls namespace right?
I don't know where wrong, please help me!
Here is the msdn page from which I copied the code:
http://msdn.microsoft.com/en-us/library/system.windows.controls.textbox.selectedtext.aspx
|
|
|
|

It would seem that you are confusing two entirely different things. If you are developing for the web, the TextBox you are probably using comes from the namespace System.Web.UI.WebControls. That control does not have a SelectedText property. You should confirm that you are linking in the correct namespace.
|
|
|
|
|
I understand, but how do I catch the selected text from an asp:textbox and put it in a string variable?
But on that msdn page I linked, it seems that talk of a web application ... is not very clear!
Thanks for the help!

Notice the namespace referenced at the top of the article you linked: System.Windows.Controls. That means it is written using Windows Presentation Foundation (WPF), not ASP.Net. In web browsers, WPF is implemented through Microsoft Starlight, which is basically a subset of WPF merged with AJAX. This lets you preserve user states, such as what the user has selected in a text box. Normal ASP is built on the HTML protocol which is stateless: postbacks are handled by sending a hidden form, which gives the information (text in a textbox) but no metadata (what part of that text is selected.) That is why the standard ASP controls do not have properties like SelectedText.
I don't think you can do what you want to do using ASP. WPF and Silverlight has a lot of very interesting and useful functionality, but there is a bit of a learning curve. You could try posting your question in the Web Development or Silverlight forums, but it might be better to either figure out a different way to get what you want, or buckle down and learn a new programming tool. Unfortunately, I've not had the time to learn it myself, so I'll just shut up now.
