thanks for the quick reply
that seems to be a good approach. I tried implement it but it doesn't invoke the action when i click on the grid.
have i forgot something? (I enabled sorting)
|

|

all you have to do is, AllowSorting = "true" and then handle the "Sorting" event (OnSorting="GridView1_Sorting"). and then click on the column names (it should be appeared as links) at the run time.

I'm using OWC 11.0 in ASP.NET and C# to create excel file.
I need to protect/unprotect the sheet by a password. I tried to protect the sheet by following code.
string Password = "Password123";
object getPasswordFromUser =(object)Password;
xl.ActiveSheet.Protect(ref getPasswordFromUser, ref obj,
ref obj, ref obj, ref obj, ref obj, ref obj, ref obj, ref obj, ref obj,
ref obj, ref obj, ref obj, ref obj, ref objTrue, ref obj);
But it throws an exception "Exception from HRESULT: 0xE0040059"
Kindly help me to resolve this issue. Code works well if I miss the password.

Because you forgot to handle PageIndexChanging event of Grid View.
On that event you need to assign new page index to the gridview and then you need to bind the data set again.
i.e.
protected void gridOrganizationDetails_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gridOrganizationDetails.PageIndex = e.NewPageIndex;
ds =
gridOrganizationDetails.DataSource = ds;
gridOrganizationDetails.DataBind();
}

i checked from data base 10 record is coming.
and i also handle page index changing event
but still that footer is with record not coming.

I've already posted this on StackOverflow[^] but haven't seen much traffic yet...
I've got a web form (set in a master page) and want to check to see if the page has any changes before exiting (either by success or redirect). If any changes have been made, a dialog is displayed and the user can click ok or cancel.
I've created a panel to act as a dialog box (change z-layer, and apply shading and opacity to background) but my problem is in handling the click events from the buttons on the dialog. For a given exit scenario, I want to do something like:
protected void btnWelcomePage_Click(object sender, ImageClickEventArgs e)
{
if (this.HasChanges())
{
lblDialogTitle.Text = "Confirm Exit";
lblDialogMessage.Text = "Are you sure? Click OK to continue and lose any data entered";
ClearEventHandlers(btnDialogOK);
btnDialogOK_Click.Click += new EventHandler(btnDialogOK_Click);
ClearEventHandlers(btDialogCancel);
btnDialogCancel_Click += new EventHandler(btnDialogCancel_Click);
pnlDialog.Visible = true;
}
else
{
Response.Redirect("~/WelcomePage.aspx");
}
}
where the event handler for the buttons will do the appropriate work to hide the dialog and redirect if required.
My problem is that the EventHandler doesn't appear to bind between postbacks - setting a breakpoint in the Click event handler doesn't do anything; the page does an empty postback.
I assumed that the postback trashes the EventHandlers so I enabled ViewState on the buttons but to no avail. Can anyone suggest a model for handling this type of change? I've been searching through google but everything appears to relate to the dynamic creation of controls rather than the dynamic assignment of EventHandlers.
Thanks in advance
Dave
It definitely isn't definatley

try to bind event with control when change are there in prerender event of the page
hope this will work because code did by you is right it should work
|
|
|
|

to add controls (with eventhandlers) on pageweb you have to add it on page-init.
try this:
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
lblDialogTitle.Text = "Confirm Exit";
lblDialogMessage.Text = "Are you sure? Click OK to continue and lose any data entered";
ClearEventHandlers(btnDialogOK);
btnDialogOK_Click.Click += new EventHandler(btnDialogOK_Click);
ClearEventHandlers(btDialogCancel);
btnDialogCancel_Click += new EventHandler(btnDialogCancel_Click);
}
protected void btnWelcomePage_Click(object sender, ImageClickEventArgs e)
{
if (this.HasChanges())
{
pnlDialog.Visible = true;
}
else
{
Response.Redirect("~/WelcomePage.aspx");
}
}
good luck

Hi
Not sure what code you are using, but you can try by using below tag
<input id="flExcel" runat="server" class="txt" style="width: 392px; height: 20px"<br />
type="file" unselectable="on" />

Hi To all forum members,
I have a search button which search records in the form, then I have to call a java script which return some values, on the base of these values I have I Have to populate Grid View.
Actually
when I clicked on search button
I) It hits to database and takes records and
II) These records are passed to java script
III) Then java script returns a value location.
On the base of java script values and code behind search criteria values i Have to populate grid view.
I am using asp.net and c# technology.
How can achieve all three steps by single click of search button.
Even i am unable to populate grid on form refresh from that java script code.
All three steps I have to perform in Single click on Search button. 
I achieved this but I have to click search button twice.

Why do you want to roundtrip?Why dont you try to simulate the javascript thing in c# itself?it'll also improve the performance.
Cheers!!
