I have a formview that I open to the edit template, some textboxes are not available and some are populated by dropdown lists, and the update function works fine.
As soon as I add some logic to the code behind page for the update control, the UPDATE link on the formview stops updating my DB.
I have a formview and data source that opens in the edit template and allows the user to update a few free form text fields. I also have some drop down boxes that allow a DOB to be built and populate another text box. All of this was working fine yesterday, and today somehow I hosed it and can not find the cause. I have rebuilt this page three times to get it working again, but I can't figure out what I am doing wrong to break it.

When i use timer control in my website. then the ajax water mark blinking.
View 1 RepliesSome time ago I converted an old windows application to a web application. This web application works fine as a stand alone app. I was recently informed that my client had a new standard layout and they are using a master page. They sent me the master page.
The web application is quite basic in that it makes a number of calls to a web service to retreive a list of customer, retrieve list of products and allows customer to create an order containing products.
I did the following to get make use of master page:
Copied it to my solution Update the page directive to include the MasterPageFile attribute and set it to point to master pageAdded the relevant content areas to my page Copied my code (control declarations etc) into the relevant content areas.The application compiles correctly and renders as expected. However, it does not behave as expected.
For example, I display a list of customers in a GridView. The user can select a customer by clicking the select button that is present for each row in GridView. I do this once and select a customer the page is posted back and relevant row is selected. I select a different customer and the page it posted back but this time the selected row does not change. It is still shown as the first row i selected.
This functionality works as expected if i remove the master page attribute and content areas.
I have an Ajax timer that has an interval of 1 second and an update panel on my page. If I leave the page open and never close or refresh I notice that after 6 to 8 hours the timer stops firing. No error messages.......everything just stops. If I refresh the page everything starts working again. Are there any issues I am not aware of when running a page for a long time using the Ajax timer?
View 2 RepliesI am using asp:ScriptManager and asp:UpdatePanel to populate a DropDown , and for every field need to display hits in div.In order to Implement the hint I am using JS, it works fine unless I started to populate a dropdown based on another one.
here is some code lines from page and JS
<asp:ScriptManager ID="sm" runat="server" EnablePageMethods="true"></asp:ScriptManager>
<asp:UpdatePanel runat="server" ID="up0">
<ContentTemplate>
<dd><asp:DropDownList runat="server" ID="CCategory" CssClass="lst" ValidationGroup="Property" AutoPostBack="true" onselectedindexchanged="CCategory_SelectedIndexChanged" /><span class="hint">Please choose a city where you want to or having a property.<span

I'm using some JS to show some divs.The divs' content is set up in a MultiView control in the server. Depending on certain parameters, I trigger some postbacks to make the server select the appropriate view. The problem is that everything works if I keep the alert(1); below, but stops working if I remove it.
Here is the code. I have a button which its OnClick() calls ShowEditor(), with an element and a type. ShowEditor() makes the editor's div visible after raising a postback to let the server select the correct view in the MultiView based on the type. This works fine. The editor loads and there is a div inside (vwText_Text1) which I'd like to assign an OnClick event to. This only works if the alert() is present.

I have a FormView that is loaded with a records from my DB. Some of the fields may be blank or null. I am trying to check the value of some of the text boxes to verify that the user has updated the fields prior to allowing a DB update from the Edit Template.
I can not seem to get the correct syntax on the if statment to check the value of the text box....

To Add new row to a dataset table, I am using code below. Before adding this how do I check if that row has already been added to the dataset?
Example:
Dim newCustomersRow As DataRow = DataSet1.Tables("Customers").NewRow()
newCustomersRow("CustomerID") = "ALFKI"
newCustomersRow("CompanyName") = "Alfreds Futterkiste"
DataSet1.Tables("Customers").Rows.Add(newCustomersRow)
Note: The table I am dealing with does not contain a primary key!
I'm using a simple search with a gridview. What is happening is when I click to edit the record, it presents me with the record fine but when I click Update in my FormView, the Gridview doesn't update. I have a feeling I'm missing something simple but I can't get totally sure so here is my code hoping someone can point the way.

i'm currently learning .Net and i can get data out of a database and display in a listview. But how can i access data items in the code behind and format, change, concatenate...do whatever i want to them then display in the list view? Is it even possible?
[Code]....
Maybe an example of what i'm trying to do would be to concatenate a address from the dataset and in a variable sAddress and then attach sAddress to a label in the list view, or add to colums of the dataset together and then show in a label in the listview.
I have a datagridview that has a column which displays a ref value from another unbound table, but during an edit of a gridview entry i want a dropdownlistbox to list all the available ref values from the other unbound table source, then to insert the selected value into the bound table

I have the following html code:

This should create a left aligned label that is 100px wide, then the list should show next to it. What happens is that the width is ignored and the list is right next to the label text. If I remove the "AssociatedControlID" parameter it works fine. CSS has no effect on the label width, even using the !Important tag.
i have a page in my webapp, in which a pdf is created. When the page is loaded, parameters are read from the querystring and the process of building the pdf starts. This contains two xslt transformations and one antennahouse-fo-formatter call. The result of the first xslttransformation is written into an memorystream, which is the source for the second transformation. The result from the second transformation is the source for the pdf-generation. Our live-system is an loadbalanced-system containing two servers. The page works for a while, but at once the page fails on one server with the following exception:

I have a grid. I am building and populating it dynamically in C#. Below mentioned is my issue:
string s1 = "string1";
string s2 = "string2";
And then I have a header cell text which needs to be populated like this.
headercell.text = s1 + new string(' ', 20) + s2;
I am not able to get the extra 20 spaces between s1 and s2. It gives me just one space instead of 20 spaces.
I tried using headercell.text = s1 + s2.padleft(' ', 30); even then I am not able to get more than one space between strings s1 and s2.
I'm trying to add an DropDownList to a DetailsView by code, because i'm writing a solution that let's the user select an table and view your records and edit them, some of theese tables, have a foreign key column and the user must have to select some item in the list.
Below is my sample code:
[Code]....
the code above is working correctly, when the user click in the buttons New or Edit , the DetailsView opens correctly, showing the DropDownlist, but when the user click in the buttons update or insert , an error occurs, the viewState cannot be loaded:
Failed to load viewstate. The control tree which viewstate is being loaded must match the control tree used to save viewstate during the previous request. For example, when controls are added dynamically, the controls added during a post must match the type and position of the controls added during the initial request.
Here is my asp and the code behind code. When I click edit and enter a new weight value, the system does not maintain that value, but displays back the original one (if I press enter I see that happening or through debug).

I am Chandan Pednekar an IT student completing my final year. I am developing a data driven website for my final year project. I have written a code behind file in c# which takes a value from a datagrid to retrieve values in textboxes for further updating.
I have coded the datagrid on another page. My problem is that, even when I click update(on editEmp.aspx) I straight away get redirected to the datagrid page(manageEmp.aspx I have redirected after successful update) but the database just doesn't gets updated. I am using sqlCommand Object with executeNonQuery method.
I don't even get errors. It just gets redirected and the database isn't even updated.

I have a test page with links that open a panel modally (using AJAXControlToolkit: ModalPopupExtender). I am using an update panel. After clicking any of the links about 10 times, the popup is shown buried under the links (and is not accessible). When I limit the content on the page, the number of times is extended. My thought is that this may be a "data limit" in relation to the update panel, as this works fine when the update panel is removed. I would love to post the code, but this form won't let me. I can certainly send the webform if anyone is interested.

Even with https enabled, you can write a password to the event log in code-behind. Any way to keep that password encrypted in code while you're checking it against a data store?
(using Login control)
(couldn't add comment to Andrew's answer, so I'm putting it here)
NTLM uses the username/password of the machine the user is logged into right? For this, I was thinking using ActiveDirectory on the server as the data store. It would have a diferrent un/pw than what the user is currently signed in to their machine as.
