I have a Gridview control in asp.net with C#.
In my application when I press the edit button from Gridview I need to open the information in another window. At this moment I use 'Response.Redirect("..")' but it opens in the same window.
I've tried:

View 1 RepliesI have a page in which I am not using cache by using this code:
HttpContext.Current.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
HttpContext.Current.Response.Cache.SetValidUntilExpires(false);
HttpContext.Current.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
HttpContext.Current.Response.Cache.SetNoStore();
Now I want to know: Is there any difference between coming to this page using a proper link or coming back using browser back button, or is there any way to detect this?

View 3 RepliesI am trying to implement Login/Logout functionality in my website without using inbuilt functionality of Login controls in ASP.NET. In some pages, which require the user to be logged in, I have written this in Page_Load
if (Session["cod"] == null && Session["admin"] == null)
{
Response.Redirect("You need to Login.aspx");
}
if (Session["cod"] != null || Session["admin"] != null)
{
LinkButton1.Text = "Logout";
}
if (Page.IsPostBack == false)
{
log_bind();
grid1_bind();
grid2_bind();
}
But while I was testing this, I noticed that when I press the Back/Forward button on the browser, these pages are viewable without being logged in. How do I prevent this?
I have a asp:button in template field of gridview, I set command name for this and in grid I mention on command event. On clicking the page it shows error message is :
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
Below is my code
<asp:GridView runat="server" ID="gridManageClients" AutoGenerateColumns="False" OnRowCommand="gridRowCommand">
<Columns>
<asp:BoundField DataField="Clientid" ItemStyle-Width="75px" />
<asp:BoundField DataField="ClientName" ItemStyle-Width="300px" /> [code]...
I'm using objectdatasource to get my data. it works fine. Thecurrentway how it works. When the page opens it loads the gridview.but I don't want this.I would like to load the gridview after I press a submit button. so infact after postback...I tried to remove the select Method in aspx and set programmaticallyin the submit button eventhandler but then I get an error thatSelectmethod is not set.Can someone advice me how I can load the gridview usingobjectdatasource after pressing a submit button?
View 20 RepliesI have a logout button on the master page.
I have a textbox on my subpage.
When I click the text box i notice that the logout button on my master page gets focus. So if the user types something in the textbox and then presses enter/return (a common reaction it appears) the user inadvertantly logs themselves out as the logout button is triggered.
Is there any way of stopping this?

i want to open the row in gridview in edit mode when i click on edit button.
How to do this in c#
In one of my Web Page, there is one Modal Pop up, in which I am using Gridview Edit, Update, CancelEdit, Delete functionality.Main functionality is : If while deleting any of the Gridview Row, if only 1 row remains in Gridview (that row can be any row), then that row should not get deleted.Rest of Edit, Update, CancelEdit functionally is working fine.
I used below code for above:
C#:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
BindGrid();
[Code]....
problem is: When any last row is left in Gridview, its Delete button is disables that time (as per requirement and functionality). But when user clicks on Gridview "Edit" button, update section opens, and at that time "Delete" button gets Enabled, so that time user can delete the last row of Gridview which should not be done.I had fixed this problem for "Cancel" and "Update" button of Gridview using below line:
Response.Redirect(Request.Url.AbsoluteUri); but unable to fix it for "Edit" button of Gridview. If Last row is left in Gridview , and user clicks on Gridview "Edit" button of that row, then at that time "Delete" button should not get "enabled" it should remain "disabled"
I have a "report" the users can run it basically creates a simple gridview. In the gridview the user can click on a claim ID. The claim id is then passed via url querystring to a claim management page. The claim management page uses a listview to display the various claims and allow users to edit them. I want to use the claim id passed in the url to locate the listview row to open in edit mode, so the user can make changes / alterations to the claim.

I have a Deafult.aspx page with a form and a button. The form consists of a drop down list and a radio button list. When I click the button I submit the form to a different page, search.aspx. When I click the back button in the browser. Somehow the radio button list values stay the same as when I last clicked them (not any special configuration by my side), and the drop down list gets back to its default value. My radio button list has a on select event that changes the values of the drop down list. The problem is, as I mentioned, the radio button list keeps its former value when I submitted the page, and the dropDownList doesn't. So they are incoherent.
How do I make them both get back to their default values? (as this is no postback... right?) or how do I keep their former values. FYI, the problem doesn't occur in internet explorer. In chrome this happens. And in fire fox, it just gets back the dropdownlist is ok, but the radio button list's default selected index isn't even selected.

View 1 RepliesI'm sure this has been asked before I just did not know how to ask it to get the forums to show up the right answer. I have a master page with a search box and then a content page with an input box and a submit button. As I'm using the program, I as a keyboard lover always hit enter after typing text into a text field. The issue is that when I'm typing in the input box and I press enter, the search boxes button will steal this enter. How can I divide the two asp.net form elements so that when I'm typing in the search box and press enter, the search button is invoked and when I'm typing in the input box and press enter the input button is invoked? An example of this happening is in the code below
[Code]....
I have a page with multiple textboxes and each has a button associated with it. This works as a search 'hub', I suppose, where the user can search by ID, name etc. When entering a search term for e.g. name however, pressing enter 'clicks' the very first button on the page (ID search), causing an error if the associated textbox is empty (which it would be if someone meant to search by name). I have attempted to rectify this using JQuery, and have written the following:
$('input:text').click(function (e) {
e.preventDefault();
$(this).next('input:button').focus();
});
I'm simply using the click event so that I can monitor where focus is redirected, but eventually I would use .keypress. However, nothing happens upon clicking a textbox and I can't see for the life of me what is wrong with the JQuery. To elaborate on the problem, the .NET code used looks similar to the following throughout the page.
<tr>
<td style="width:100">Company ID</td>
<td style="margin-left:3px;">
<asp:TextBox ID="...TextBox" runat="server" Width="230px"></asp:TextBox>
</td>
<td>
<asp:Button CssClass="Button" ID="...NameSearch" Text="Search" runat="server" /></td></tr>
This is generating this (view source):
<td><input name="...TextBox" id="...TextBox" style="width: 230px;" type="text"/></td>
<td><input name="...NameSearch" class="Button" id="...NameSearch" onclick="javascript:__doPostBack('...NameSearch','')" type="button" value="Search"/></td>
I'm using a ModalPopupExtender to display a login screen when an ImageButton (called Post) is clicked.The dialog pops up as expected and performs all the correct validations. When the user presses the Enter key, this causes the Login button to fire its Click event as it should.The issue I get is that I have another ImageButton on the main page. After the user presses Enter in the login and the page logs the user in, it does not fire the server click even for the initial post button that brought up the login, it fires the click of another ImageButton instead.
View 1 RepliesI am trying to generate a gridview dynamically through codebehind. So I am making all the columns through code using BoundField and other controls.Now I am trying to to put a edit button in the gridview sand program that(I made a RowEditing handler). Right now all my code is in the page_load but when I hit the edit button in the gridview I get 2 gridviews back on post back.So I tried to put a isPostback if statement to stop this but then I just get a error back saying it can't find the handler.
