It is, as you might have guessed, the text box from an on screen PIN pad. Javascript fills in the values. The page is posted back every five seconds (using an update panel if that matters) to update various other unrelated items on the screen. This works just fine. However, when I convert it to a password text box, like this:
Then whenever the page posts back, the text box is cleared out on the screen and the textbox is empty (though during the timer event, the value does make it back to the server.)
I have an asp:UpdatePanel in my .aspx page.Within the panel I have placed an infragistics ultrawebgrid control.Upon clicking a button (placed outside the panel) , I have to export the data in the grid to excel.I am using
UltraWebGridExcelExporter(Infragistics object) for this. The export will occur only with full postback.For this I have added a PostBack tigger for the button to the update panel.But once the export is complete, if I change the selected item in a dropdownlist(Autopostback="true") in the same page,the updatepanel gets invisible.
I've coded myself into a state of confusion. I have a form with a postal code TextBox and a country DropDownList both inside an UpdatePanel. When the selected country is changed, the DropDownList auto posts back and sets the regular expression used for validating the postal code. The country DropDownList also has a RequiredFieldValidator. The first item in my DropDownList is empty (Value = Text = String.Empty) and when I select this item, I momentarily see the RequiredFieldValidator appear and then disappear. It seems that the client side script is displaying the error message, but then after my partial postback it disappears. I can see in the country DropDownList's SelectedIndexChanged event handler that the RequiredFieldValidator has IsValid = false, so why doesn't the error message stay visible?
If I click this button it is working OK (it will respond with a PFD file so no HTML is sent back to the browser), but if I click another button on the page (which makes a full postback) the LinkButtonPrint will not have the inner content, it will be rendered like this:
<a href="javascript:__doPostBack('ctl00$LinkButtonPrint','')" id="ctl00_LinkButtonPrint" onclick="StartLoadTracking(this, 'Loading...');"></a> If I remove the LinkButtonPrint.Attributes["onclick"] = ... line from Page_Load everything works fine (except my js function is not called, but that is normal).
What am I missing here?
EDIT This is duplicate of asp.net Link button image not visible after postback.
I have a gridview where in the users are allowed to edit certain data and there is an update on top of the page which will send out all the changes made inside the GridView. But, the problem is , as soon as the update button is clicked, the grid disappearsand no update is made. This problem occurs when the size of the data on the page is huge. When we have less amount of data on the gridview, It does update. But, when there is a huge amount of data on the gridview, it does not. We have tried to increase the page size on the server, but to no use.

I have written a javascript code for handling the password functionality. The scenario is: when user wants to change the old password, he cannot fill the same old password again. I have written the code. But even the simple alert of blank textbox is not working. See the code for reference:
Javascript code:-
<script type="text/javascript"> function ltrim(str) { var reg reg = /^s+/g return str.replace(reg, "") } function rtrim(str) {
I have a datarepeater inside which I load a gridview. After the grid's binding is done I create an extra header line to group the columns (that's the only way I could do it, I couldn't figure a way to add an event for a control inside the repeater).That works fine and the page displays perfectly.However everytime I do a postback from other controls, I lose the 2nd header and 1 extra empty line appears at the top of the gridview
have an ASP.net 4.0 page containing a GridView, where during the Page_Init event I'm dynamically adding BoundField columns to the gridview. I also have some custom sorting and paging methods that I use with this gridview, which result in postbacks on the page. In Chrome, Firefox, Safari, and Opera the gridview behaves as expected. HOWEVER, in IE 6, 7, or 8 when I click to sort a column in the gridview, or go to the next page of results in the gridview, it does not bind on postback, returning nothing back to the browser. Again, in anything but Internet Explorer, paging and sorting (frankly any postback event) brings back the gridview in its expected state. I only have the problem in IE. Relevant snippets of my code follow, where you'll see my Page_Init event calling a method in my WebFunctions class to add the BoundField columns for the table I pass to it, and my Page_Load event that calls the method in the user control responsible for binding my dataset to the gridview. Initial page load works in all browsers, but postback loading of the gridview only works in non-IE browsers.

I have a page with an UpdatePanel with a UserControl in it. That UserControl contains a GridView with a nested UserControl that seems to disappear when the parent UserControl is rebound. I cannot for the life of me figure out why the child UserControl disappears. The code works beautifully on the first load, but any partial postback causes the "Pick" UserControl to disappear.
I have 2 textboxes and a submit button inside a .net composite server control. I tried to only postback when submit button is clicked. I set autopostback = false for both textboxes. But either one still trigger submit button's onclick event by hitting "Enter" inside textbox. How can I stop postback by enter key?
When the finish button is clicked on the third step I would like to Create the user and send the form. I have the logic for this written but the only problem I have is the when the next button is pressed on a wizard, a PostBack occurs and my password field:
I have written a simple jQuery dialog box that will appear in an asp panel if the logged in user has not reset their password in the last 90 days. This is working great, however when the user types in their password and presses submit to insert the new password into the database, the parent page is posting back before the click event is fired on the user control.
Here is how it is set up:
default.aspx <asp:Panel ID="pnlTest" runat="server" Visible="false"> <div id="dialog" title="Password must be reset"> <cms:ResetPassword runat="server" ID="reset" />
[Code]....
Whenever I click the button to change the password, the default page is calling a postback and it is blanking out the text that was input to change the password, so when the click function gets called the strings come through as "" and it throws an error.
I have a Username and Password field on webform and a Submit button.Username ia validated through database on button click.Each time when i click on submit button and if Username already exist then my password gets to be removed due to postback.Please give me some solution so that when i just defocus my username field it will automatically check and display message if it exists.Please donot give Textbox ontextchanged event with update panel in conditional update mode because it will not work for me because i am using devexpress tools on my webforms.
I'm just starting out with WebMatrix and would like to know how to style a @Html.TextBox("email") and @Html.Password("password") control? I've tried (in my CSS file):
.email{ /* styles here */ } .password{ /* styles here */ }
But that has no effect at all. How can we style these types of controls?
I am having a problem in showing password from my database in a textbox in password textmode. When I change the mode of the textbox to 'singleline' , the password is shown but when I change it back to Password mode, it is not shown. I am using C# with ASP.NET with MS ACCESS database.
