You are going to have to write code to do that.
Office 2007 / 2010 uses the OpenXML format, so in order to

You are going to need to manipulate the actual document yourself. You are going to have to read up on the OpenXML format and then write some code to accomplish your task.
If you don`t want to
watchdogger wrote: export the whole website or the whole page to a file
Then don`t code it that way.
If at first you don't succeed ... post it on The Code Project and Pray.

Hi! in future post, try using the code block  just for better understanding of the code 
Well, the Control, must be a GridView, so you can add
public static Control FindControlRecursive(Control Root, string Id)
{
if (Root.ID == Id)
return ((GridView)Root);
if (Root is GridView)
{
GridView gv = ((GridView)Root);
Int32 num = 3;
Int32 row = 1;
Control FoundCtl = ((Control)gv.Rows[row].Cells[num].FindControl(Id));
if (FoundCtl != null)
return FoundCtl;
}
return null;
}
Remember that in ASP.NET the dinamically controls added like in grid view Template field, have the same name, except in Client-Side. if you want a especific row, you only need to change the row parameter

I am new to web applications.
I wish to do an e-commerce site.
I wish to use ASP.NET , C#.Net and SQL Server.
What is front end and back end?
for a two tier application I think we say VB.NET as a front end and SQL Server as a back end
I think an e-commerce site is a three tier application
I preferred ASP.NET, C#.Net & SQl Server.
Which one of these are called as a front end and the backend?

When I click Button1, Button2 gets enabled and the label's text is set to "bye". This is done with a bit of javascript. When Button2 is clicked, it's text should be set to "bye" - the new text value of the label, but is set to "hello" instead - the original text value of the label. How can I fix this?
Aspx:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Test</title>
<script type="text/javascript">
function Hello() {
document.getElementById('Button2').disabled = false;
document.getElementById('Label1').innerText = "bye";
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input id="Button1" type="button" value="Button1" onclick="Hello()" />
<br />
<asp:Button ID="Button2" runat="server" Enabled="False" Text="Button2"
onclick="Button2_Click" />
<br />
<asp:Label runat="server" ID="Label1" Text="hello"></asp:Label>
</div>
</form>
</body>
</html>
Cs:
protected void Button2_Click(object sender, EventArgs e)
{
this.Button2.Text = this.Label1.Text;
}

}

I need to use the label's new text value in the code behind for further processing. Using 'this.label1.text' doesn't work as it gives the original text value not the new one.
|
|
|
|

Oops sorry. Can you not simply use the code-behind to solve this issue?
Because your clicking on a server control the page is reloaded back to its orginal state. If you want to change the text of the button after changing the label control using JavaScript then you will need to change the second button using JavaScript also.

No. I am working on an application that utilizes a scheduling control. This control has a client-side click event that I must use. When I click on the control it must set a property wich in turn must be used when a button on the page is clicked. My solution to this was to set a label's text property but that doesn't seem to work, as you have seen in my code. Maybe you can help me out. Thanks anyways.

Only other way I can think of is to use a hidden field.

document.getElementById("<%=Button2.ClientID %>").disabled = false;
document.getElementById("<%=Label1.ClientID %>").innerText = value;

Thank you very much! It works!

When I click button 1, button 2 must be enabled and the label's text must change from "hello" to "bye". This must be done clientside through Javascript. How must I change the following code to get this to work? When I click button 1 the label's text changes but immediately reverts back to it's original value.
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Test</title>
<script type="text/javascript">
function Hello() {
document.getElementById('Button2').disabled = false;
document.getElementById('Label1').innerText = "bye";
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="Hello()"/>
<br />
<asp:Button ID="Button2" runat="server" Enabled="False" Text="Button" />
<br />
<asp:Label runat="server" ID="Label1" Text="hello"></asp:Label>
</div>
</form>
</body>
</html>

When you click the button the client-side script is being executed properly, however, it also causes a post-back which resets the page. If all you need to do execute client-side script with no post-back then change the asp:button controls to simple html elements <input type=button>

Or just put a
return false; in the Hello function.
That should also work.

Only if he includes the "return.." part in the OnClientClick
also. Like:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Test</title>
<script type="text/javascript">
function Hello() {
document.getElementById('Button2').disabled = false;
document.getElementById('Label1').innerText = "bye";
return false;
} </script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="return Hello()" />
<br />
<asp:Button ID="Button2" runat="server" Enabled="False" Text="Button" />
<br />
<asp:Label runat="server" ID="Label1" Text="hello"></asp:Label>
</div>
</form>
</body>
</html>

Could you perhaps explain the purpose of these return statements?
|
|
|
|
|
Returning a value in a javascript click event handler tells the browser whether or not to continue normal processing of that click. For a submit button, returning false tells it to stop processing a not to actually submit the form. Returning true allows it to continue submitting the form normally. For a hyperlink returning true would allow the browser to navigate to the URL and returning false would leave the user on the curernt page.

return statement is to avoid PostBack.
"When I click button 1 the label's text changes but immediately reverts back to it's original value."
this is because of PostBack

Yes. And that's what I said.
His Hello() function is called on OnClientClick. I missed the return in OnClientClick part.
I am sorry I didn't explain it.

I believe someone posted an article or tip/trick regarding this a few days ago though can't find it now. Try searching through recent articles.

Hi, I have a generic list of objects returned and I want to store it in a datatable in viewstate as I have to do some in memory operations on the list (edit,update,delete)
How to go about this task ?

Hi I have a gridview which has some records (recordID is being fetched from database)
I load the results in datatable which has columns like
--------------------------------------
RecordID | EmployeeID | Name | Address
--------------------------------------
1 4 John xyz
2 5 Smith xyz
Now user can edit the records with a checkbox list (problem is that he can reselect the existing checked items again, so the recordID is null for reselected items, I set it to zero to distinguish all new records)
So the new datatable becomes
--------------------------------------
RecordID | EmployeeID | Name | Address
--------------------------------------
0 4 John xyz (reselected rows with 0 id)
0 5 Smith xyz (reselected rows with 0 id)
0 8 Evans xxx (new record)
Now I am on form update button, I am trying to figure out how to find which records to insert and how to find records to do nothing with ? The reselected records already existing in database are creating problem for me.
Mike.
