private void adddescription()
   {
       int rowIndex = 0;


             if (ViewState["CurrentTable"] != null)
             {
                 //DataTable dtCurrentTable = (DataTable)ViewState["CurrentTable"];

                 DataRow drCurrentRow = dtDesc.NewRow();
                 if (dtDesc.Rows.Count > 0)
                 {
                     for (int i = 1; i <= dtDesc.Rows.Count; i++)
                     {
                         //extract the TextBox values
                         TextBox box1 = (TextBox)Rptdescription.Items[rowIndex].FindControl("TextName");
                         TextBox box2 = (TextBox)Rptdescription.Items[rowIndex].FindControl("TextDate");

                         ViewState["RowNumber"] = drCurrentRow["RowNumber"];
                         Label1.Text = ViewState["RowNumber"].ToString();
                         dtDesc.Rows[i - 1]["DescriptionName"] = box1.Text;
                         dtDesc.Rows[i - 1]["Date"] = box2.Text;
                         dtDesc.Rows[i - 1]["Description"] = box3.Text;

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.

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

First how You are trying to display the number of seats. are you trying to use the buttons or any control.
I suggest you the update panel because it will not refresh the whole page .

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,

In each system it wil be prefixed with Local host number. the same code is working in other system. then what would be the problem? On ur suggestion i had right clicked on the image this was the link http://localhost:49216/ws/App_Data/pics/pic1.jpg in this except local host and its number my path is same

asp:TableCell ID="TableCell4" ColumnSpan ="2" VerticalAlign = "Top" HorizontalAlign ="Center" runat ="server">
