How To Show Confirmation Box If Data Is Changed On Page
Dec 23, 2010
I am showing a few textbox controls on a page and I have a Save and Cancel button. If the user makes a change to any of the textboxes and clicks cancel, then I want to prompt the confirm box if they want to cancel with data being changed. I can determine if data has changed by comparing session variables of the data to the actual values. And I know how to show a confirmation box using javascript. But it seems like I need to call this from the vb code rather that right there on the client?

I've a textbox in grid view control. When user inserts some value in textbox a confimation message should be displayed to user. eg. "Do you want to update record?". if user clicks on yes/ok then some code should be executed else if user clicks cancel/no the return to same page. I've tried using
ScriptManager.RegisterClientScriptBlock(page, page.GetType(), "key2", "confirm('Do you want to update?');", true); on text changed event of textbox. But was not able to achieve desired result.

I am trying to use Yes No Confirmation Message Box but the code below here which i found here uses a button to raise the confirmation message box but what i would like to use is a DropDown. How can i modify the code and i use drop-down box instead of using a button? here is the javascript code:
<script type = "text/javascript">
function Confirm() {
var confirm_value = document.createElement("INPUT");
confirm_value.type = "hidden";
confirm_value.name = "confirm_value";
[code]....
but here is what i would like to use is drop-down instead of the button:
<div>
<asp:DropDownList ID="ddl" Width="300px" runat="server" AppendDataBoundItems="true" OnSelectedIndexChanged="ddl_SelectedIndexChanged">
<asp:ListItem Text="test1" Value="test1"></asp:ListItem>
<asp:ListItem Text="test2" Value="test2"></asp:ListItem>
<asp:ListItem Text="test3" Value="test3"></asp:ListItem>
</asp:DropDownList>
</div>

I have one page which contains 3 panels and 3 buttons. Each panel connects one button. When one button clicks, the relative panel appears and other panels are divisible. For each panel, I design a textbox, a merge button and a gridview. When user input information into the textbox, the gridview shows the detail data from the database and two checkboxes. The next step, user uses checkboxes to choose two different rows of data and click the merge button. I need to show a confirmation message based on the selection user made i.e. Are you you want to merge A to B.
write the code to show the confirmation message which is works perfectly in Page_Load() method. But the problem is the page contains 3 panels. Do I need to write code for each panel to show the confirmation message and put 3 sets of the code in Page_Load?
see my code below.

I am throwing a alert box using scriptmanager like this based on some condition.
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "alertMessage", "alert('Would you like to be put on the wait list?')", true);
But it has only "ok" button. Is there a way to display a message box which has yes/no buttons so that I want to check some more conditions in the code behind.
something like this.
DialogResult result = MessageBox.Show("Do you wanna do something?", "Warning",
MessageBoxButtons.YesNoCancel, MessageBoxIcon.Warning);
if(result == DialogResult.Yes) {
//code for Yes
} else if(result == DialogResult.No) {
//code for No
} else if (result == DialogResult.Cancel) {
//code for Cancel
}

I have a grid view where the user can change pages at either the top or the bottom of the grid view. I want the view to go back to the top whenever a user changes the page, whether they are changing from the top or the bottom. I've tried using anchors and javascript to achieve this but it does not work. The javascript is executed and the user is taken to the top of the gridview, this can be seen by placing an alert after the javascript to change the view. But the last thing that happens on the page change is that the window is returned to it's previous position (the bottom of the page). Is there any way of doing this?

I have this function:
[Code]....
I set itemsRead and startRowIndex in ViewState:
[Code]....
This is my PageIndexChanged event:
[Code]....
My purpose is to modified some data only for current page in a gridview. I call this function in page load and GridView_PageIndexChanged events. When it's called in page load event, it works fine. But when it's called in PageIndexChanged event, only the rows on the first page in GridView are looped through. For example, if I click page 5, the rowStartIndex becomes 100 = 5 x 20 (my pagesize). The if condition becomes itemsRead >= 100 andAlso itemsRead < 120. But after itemsRead is increased to 19, the For each gridViewRow loop stops and the if condition is never satisfied.

I'd like to know how I can warn a user when they're leaving a page where they've changed data (i.e. "You have unsaved data on this page, are you sure you want to abanon it?"). For example, the page has a few dropdown lists, some textboxes, etc. I'd like to warn them if they try to leave the page before saving the data. How can I do this? To add to my confusion, I also have a dropdown menu control (skmMenu) on the page that doesn't seem to have any events I can tie into.

I have a gridview with paging. I have a style set for a selected row (highlights the row in light orange). What i would like to do is that each time a user chamges the page, the selectedIndex & selectedRow automatically becomes the 1st row of the selected page. So i would like to see the orange highlight on the 1st row of the page to indicate that the row has been selected.
I have tried GridView1.SelectedIndex=0 but this only seems to select the index of the 1st record in the whole datagrid. Does anyone know of how to set the 1st row of the page to the selected row each time the pageindex is changed?

I have 3 nested grids as Parent/Child/GrandChild and I have assigned SqlDataSources to all the grids at declaration time. I place the SqlDataSource next to each grid as follows.
<GridView>..</GridView><SqlDataSource>..</SqlDataSource>
Because of this I am not doing anything in RowDataBound(...) event. But I used the RowCreated(..)event of Parent and Child grids to access session (Please look at the select statements of Child/GrandChild grids).
Parent grid's RowCreated(..) event puts the value in the session which is used by Child grid. Child grid's RowCreated(..) event puts the value in the session which is used by Grand Child grid.
GrandChild grid has paging enabled and whenever I click on page index, Child and GrandChild grids goes blank. Parent gird doesn't go blank because its select statement doesn't take any "select parameters".
how to overcome this problem. I am attaching .aspx and .aspx.cs files

How do I redirect the page once the user has seen the confirmation page?
I am using asp.net 3.5, it's not showing me a message instead it's just redirecting to the default page. I want to see the message and once the user has clicked 'ok' then it redirects to another page.
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), key, "jAlert('" + msg + "','" + title + "');", true);
Response.Redirect("default.aspx", false);

<asp:CompleteWizardStep ID="CompleteWizardStep1" runat="server">
<ContentTemplate>
<table border="2" style="font-size: 100%; width: 320px;">
<tr>
<td align="center" colspan="2">
Complete
</td>
</tr>
<tr>
<td>
User account has been successfully created.

After some code change I have published my AJAXised web application to the server and the application failes to work properly - something weird is going on, as all .aspx pages are displayed as an ASPX markup text (page declaration, html controls, etc.), rather than a page is being rendered as an html. I have not changed the webconfig, only changed my pages' content/code behind.

For our ASP.NET project for school we had to build a sport event management web application.
We provide the application in three languages (English, Dutch & French) which you can switch all the time. This has worked all the time for all users, well that's what we think anyway.
Yesterday I found out that switching from one to another language isn't working for 2 of our users. So I started testing a bit and I always got this error.
I'll try to explain what happens behind the doors when changing the language:
First of all the current language is saved in a session so we don't have to check the user row every time a page loads. Besides that we save the language in the users row in the database.
Users Table:
Id int
Unchecked
Email varchar(150)
Unchecked

I have a Datagrid on ASP.NET web form which I have bound to a data source and set it to have 10 records per page. I also have a hyper link column on the Datagrid , such that a user can navigate to another page (details page) from the list. On the details page, they have "Cancle" button to return to the Datagrid pageI am looking for sample code snippet on the Server Side on how to specify the page index to set the Datagrid after data binding. The idea is to ensure the user navigates to the same page index they were on.
