Web Forms :: User Control Does Not Let Me Assign Values Into Text Boxes?
Dec 14, 2010
(using c# and .NET 2008):
I have a main web page and added a user control inside it. The user control has some textboxes. The problem I have is when I populate the textboxes with the data that is in the DB, they do not show the values. The strange thing is If I change the property of textboxes ReadOnly to TRUE, they show the values. The problem is that I need them to be ReadOnly=FALSE.
I had called the data from query to data table and now i have a gridview in which i am using one datalist and 2 text boxes and and reming coloumns are bounded iahve to assiaign them values which datatable have either null or any value.
My User control code:
And the Data Repeater is something like this:
Here, Immediately after the userControl <ucAB:....> line, I am printing the userid just to see if its valid (by <%# Eval("UserId") %> and the user id's are valid too. I dont understand why the User Control cant pick it up on ajax postback?
Using C# and SQL as the database.I have a page with a gridview and some text boxes and drop down list boxes. A user selects a record from the grid view I query the database and fill the text boxes and drop down list boxes.
Some fields get updated periodincally thus there is no data in those fields in the database until some time.
A strange thing happens.When filling data some text boxes gets a one tab spacing .
I have a gridview in my aspx form. I have used template column & in that created a table. In the table of the Item template , I am displaying some fields. My requirement is that when I click on any row, the correspoding data should be placed in proper text boxes. Each row in itemtemplate has a unique id called UserId.
User enters values into text boxes (personal information etc.) and then presses a save changes button. The values in these text boxes get stored in an SQL database. The problem I have is that when updating the database using the values from the text boxes, the page refreshes and the values in the text boxes are lost (or rather they return to the values that are already in the database as the data from the database is loaded into the text boxes on Page_Load). When I update the database using valuse stored in variables it all works fine. What is the best way to update with the values from the text boxes?
I am hoping this is not a silly question but I have been struggling to find an answer. I have created a web application to insert data into SQL database using T_SQL and stored procedures as I needed to update several tables at the same time. The design of a particular page is using text boxes and dropdown list's and not the default gridviews or details view as I wanted the page structure set out in a particular way. Anyways I now want to create an update page which I will get redirected to from a search page.My question is how do I assign the column values to text boxes or Dropdown lists from my Select statement. I was thinking of having a event in the page load method. Sort of like this 'Select InvoiceID, Invoicetype, Notes FROM TblInvoice Where Invoicenumber = @Invoicenumber " the parameter value @Invoicenumber will be assigned via the search page so I will also need to pull that in on the page load event. So my page would look something like this if say the:-
I am making a Http Module for authentication in my web application in asp.net 2.0. When the AuthticateRequest event is fired then I get the userid and password values from current request. But Every time I am getting null in both. My code is here
I'm using a modalpopup in my C# page. Each time a user clicks it, the values in the modal popup should be empty, but instead, the values from the previous time they clicked it remain in the text boxes. Here's my code..
I've created 3 buttons, first button is to load the values in textboxes added to placeholder. Then button2 is to extract the data from button 1 and display out. Now the 3rd step, I want to edit the values from the textboxes, after edit, how do I grab and display out the new values in label and textboxes?

I'm new to ASP.NET. I 'm trying to figure out how to make an HTML/ASP page where a user puts in data, either in text fields or selection boxes, and on clicking a submit button all of there selected data gets dropped either into a Access 97 Db or an excel spread sheet. Are there any examples out there of this? Is there a place that has already created this and I can just look and the code and figure it out for myself?
I am trying to figure out how to get the text value from each textbox on a page that has a dynamically created number of text boxes. I need to store that value in a database row. I guess what i need is to be able to store the text box values in a collection or arrary of some sort and then be able to use textbox(i).value or something of that nature. Not really sure where to begin.
