Web Forms :: Dropdownlist Programmically Fills Data In Webform?
Sep 23, 2010
I am trying to get a dropdownlist to fill a webform.My approach is to have the dropdownlist to be bound with data from the database. OnSelectedIndexChange for the dropdownlist, I would like to query the database to get the form data. Once the form is filled, changes can be made, then saved again...writing changes back to the database.These seems very simple, but I am stuck. My dropdownlist posts to the server to get the data, but I think this is submitting my form...which cannot have some empty form fields.
What I am looking for is a new way to approach this task ( I have gotten tunnel vision ).

I have a SQL datasource, hooked to a gridview. When i submit my updated row, the update parameters fills with the original values, instead of the new values. Am i doing something wrong? I have tried to handle everything in the html, and not code any parameter settings. All my update parameters are called the same as the field in my gridview, and i use a prefix infront of the parameter names in my updatecommand, in my case : (instead of @) since i use oracle.

I have 2 Imagebuttons on a nested Masterpage. When I click one button I want load a content page and change the image of the clicked button to show that it was selected. Loading the content page goes okay but I can't seem to programmically change the image of the button. I have been reading the posts on the life cycles of MasterPages and Content pages and I think I have the code in the correct page but it is not working. I am so confused now.

I am using a server control on a single web.forms page. I have to use this control on a web.forms page since its a server control, although this is actually a MVC project. So I created a web.forms folder and put my new page in it. I then copy the example code from the signature control. I get the following error:
The base class includes the field 'ctrlSign', but its type (WebSignatureCapture.SignatureControl) is not compatible with the type of control (ASP.signaturecapture_signaturecontrol_ctlsignature_ascx).
I know the code works because if I removed the ID attribute from the server control, it no longer gives me this error and my control renders. But I need the attribute for the ID so I can perform is post event
I am using this signature control. Here's the web.forms code...
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Index.aspx.cs" Inherits="KahunaCentralTIDRevamp.SignatureCapture.Index" %> [code]....

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 am trying to find an efficient way of displaying images (about 140x140px) in a webform. We cannot use paging, so we need to display all these images in the same webform.I noticed that facebook (and other sites) lets you display all your images in one page. For a profile qith about 1000 photos, facebook somehow downloads only enough so that the visitor can see images on the screen. Once you scroll, it seems to only download enough so that the visitor can again see something on screen. It works like a good text editor.... instead of displaying a huge file onscreen (like notepad does) and freezing, it only displays enough for the reader to see.

I'm new to all of this, so go easy on me. This should be an easy one. I have created a custom SmartContentBlock user control for a CMS.The control works, but only if I invoke the Fill() function in the Page_init event in the codebehind of the ASPX page. My goal is to modify the class file so that the Fill() in the codebehind is no longer neccesary. So, for reference, here's the gist of the current situtation.Controls.cs

I am trying to create a recipe system that will pull material amounts from an already built inventory database upon request for testing purposes of the different recipe runs. What is throwing me for a loop is that each time a user will request a recipe comparison they will have a different number of recipe trial runs for comparison purposes. In order to do this I'm guessing you will need to generate a gridview-like control with a dynamic number of columns which would be specified on a web form page prior to arriving at the recipe formulation page which will contain the control for the recipe formulation. As a result the user will have different columns and rows on this formulation page, with the rows being a static number of 30 (30 being maximum amount of ingredients to include in each recipe). The columns will contain the recipes to be compared, i.e. ProductRun1, ProductRun2, ProductRun3, where the number of ProductRunX will be determined by user input. So the user when they come to this aspx page will be presented with a blank editable grid of X columns by 30 rows deep. The left-most column will contain the ingredient names in a drop down box for users to select to input into their recipe and the rest of the columns will be editable fields where the user can type in the amount of each material to be used. The setup will look roughly like this:
| ProductRun1 | ProductRun2 | ProductRun3 |
ProductRun4 | ... |
-------------------------------------------------------------------------------------------------------
Material1 | Material1_Amt | Material1_Amt | Material1_Amt | Material1_Amt | ...|
-------------------------------------------------------------------------------------------------------
Material2 | Material2_Amt | Material2_Amt | Material2_Amt | Material2_Amt | ...|
-------------------------------------------------------------------------------------------------------
Material3 | Material3_Amt | Material3_Amt | Material3_Amt | Material3_Amt | ...|
-------------------------------------------------------------------------------------------------------
(...)
-------------------------------------------------------------------------------------------------------
Material30 | Material30_Amt | Material30_Amt | Material30_Amt | Material30_Amt | ...|
-------------------------------------------------------------------------------------------------------
So my question is how would I go about tackling something like this and what controls would I use. All of the forum posts around the internet show the GridView control being tied to data in a database already and not having the ability to have a fully blank and editable table upon the page loading so that it can accept user input. Another wrench into the situation is that the column numbers can vary. What control would be used in this situation or would it be better to use just a repeater of textboxes to build this type of control? Another thing is once the control is built how can you pull the data from such a control with the intentions of entering it inside a sql server database?

Using VWD 2010 Express.
I tried to put a ListView onto a webform but got an error right after that:
Error Creating Control - ListView1
The 'CssClass' property cannot be set declaratively.
BTW, does ListView support horizontal/vertical scroll bar? As I might have about 50 records in maximum, so need to have horizontal and vertical scroll bars. But do not need paging.

In my ASP.NET WebForms application, I have a WebForm that contains an UpdatePanel and multiple views used for a wizard like interface. At the end of the wizard, the user has an option of moving to another page by clicking a button. This new web page needs about 5 values from controls in the previous page.What is the simplest way to do this? (Edit: ONLY using an HTTP POST with data - this is a requirement as I would use database/session otherwise)
