Web Forms :: Create TextBox Dynamically Through Web Service
Feb 19, 2013
I am having some problems creating a asp textbox dynamically in a webservice and a ajax calendar extender. Is this possible to do. I did the example with the dynamic lable and that works fine, but when it comes to creating a textbox i get this error "Control 'txtSDate' of type 'TextBox' must be placed inside a form tag with runat=server"
Here is my code.
[OperationContract]
public string LoadUserControl(string message,int id) {
using (Page page = new Page()) {
UserControl userControl = (UserControl)page.LoadControl("/UserControls/BudgetItemTD.ascx");
(userControl.FindControl("lblBudgetName") as Label).Text = message;
I have a dropdownlist("ddlTemplate") control and a gridview("gvPlanning") control with 1 BoundField column, 1 TemplateField column and remaining columns will be generated dynamically from database.In TemplateFiled Column i have 3 image buttons viz: Edit, update and cancel.Gridview will be populated based on the selecteditem of dropdownlist.
if i click on edit imagebutton, i need to add textboxes dynamically in all the columns of that row except first 2 column. And if i click on Update imagebutton i need to retrieve the textbox values.we can add template field column for textboxes also, but why i am sticking to this method is.. the number of columns changes depending on the selecteditem from the dropdownlist. Eg: If i select india from dropdownlist the number of columns in the gridview would be 4 and if i select UK from dropdownlist the number of columns would be 9 likewise.
I'm currently in the process of creating a webshop. This webshop supports theming, but I also want customers to choose a lay-out. I can create multiple masterpages and create a handler to dynamically set the correct master page. But some components, like the shopping cart, are controls which have to be present in the master page and are also used in the aspx pages. The shopping cart control for instance, has an Update method which is called whenever the user adds a product to their cart. So the question is: can I somehow create a default masterpage which has all the components on it, but still be able to create multiple lay-outs. And how should I reference that master page from the aspx pages? I also thought of creating an Interface class which defines the masterpage and it's public components, but I don't know if I can reference an interface from aspx pages.
I developed a web service in VS2010 on my local machine, wrote a consumer of it also locally, and that all works.
I copied the dll and the asmx file to our server, and I am getting an error when I try to invoke it from a browser (also still on the server machine) to make sure it correctly exposes its web methods, but it is not, it is saying "Could not create type 'Service'". That error comes from this line:
Line 1: <%@ WebService Language="C#" CodeBehind="~/App_Code/WarrantyDuplicate.cs" Class="Service" %> There other web services in the same folder on the server that all work fine so I don't believe it's an IIS setup thing.
This is my first web service in C# and when I created it in VS I did think it odd that the code behind file went into App_Code (as you can see from the line in the asmx file) and is just named dot-cs rather than asmx-dot-cs. But since it worked fine locally, I wasn't sure that mattered.
How to create an instance of web service without adding web service reference? How to identify the server address/name where the web service is hosted from C# code?
i want to create a web service which consists of CRUD operations Create, Retrieve, Update and Delete. creating web methods on insert and update operations.
i m trying to create some sort of dynamic textbox in my web form, i have a textbox where i enter a number and i want to create textbox as much as the number,
i tried to create tables formed by only rows, it worked but the problem is that the textbox are not created in the page, they are created at the buttom, how can i center the textbox created or position them,
I'm using multiple file upload. I'm following this link [URL] . I can able to save multiple files. Now i want add textbox to all file upload. I can add HTML Text box. I don't know how to find that? I'm using following code to upload multiple files..
I have a form that has dynamically generated textboxes using javascript.
My question is how can I read the values of these dynamically generated textboxes since I dont see any HTML in the page source for these textboxes even though they appear in the page.
I tried to read using
var str = document.getElementById('txtHello').value;
It always returns null.
txtHello is the Id which I have given to the textbox when I generated it dynamically using javascript.
I am generating a button dynamically at runtime and in event button click I am generating a TextBox dynamically at the runtime.
My question is I should be able to generate TextBox on every click. Suppose say, If I click three times then there should be three textboxes generated.
I have a form that loads information from a database and then puts it into a label. I want it to add a textbox for inputting information for each row it loads into a label. I can't seem to figure it out though. I have tried just adding the label to the textbox as well as doing how I have it now.
like if i have a button and i would like when that button is pressed that a completly new page is generated with some elements in it and some code in the code behind.
I want to dynamically create asp textbox objects (as well as other types) with id's named sequentially up to a number the user decides but I'm having a problem getting my code behind to recognize these dynamically created objects. In "div1" below I manually create the objects and I have no problem getting the values in Sub cmdSaveDiv1Info_Click. My dynamically created code generated in Page_Load routine is identical to that in "div1" except for the textbox ID's yet when I try to retrieve the values the same way in cmdSaveDiv2Info_Click I get an "object reference not set to an instance of an object" error on the "Dim d2Year as String.." line.
I have a page that contains many textboxes. It is like 9 textboxes for everyday in a month, and their numbers and IDs are changing dynamically for every month change on the page. I'm creating them in many for loops like;
[Code]....
This was just an example not real code. Now I want to add those textboxes the same TextChange event. How can i do it? I'm a little bit newby at asp.net. Sorry about that...
I have a dynamically-generated textbox and a static text box. They both have enableViewState = false. On the web page, I enter "ABC" in both textboxes. In the code-behind I set both text boxes to "EFG" in the page_load event.
In debug in page_load I can see both textboxes say "EFG". This is what I want.
When I hit the LoadComplete event, the STATIC textbox still has "EFG", but the dynamically generated textbox has gone back to "ABC".
I went one-by-one through all properties on the dynamically generated/static textbox, and they are all identical.
I am trying to create a comment system in which the comments will be displayed and will have one level of reply to the comment.
I now have text boxes and buttons dynamically created under each comment for users to submit replies to each individual comment.
I am having difficulty obtaining the contents entered by the user within the text boxes.
[Code]....
The GetComment method is called at pageload. I am able to obtain the Id of the comments that the reply corresponds to, but not able to obtain contents entered by user in the reply text boxes, they show up as blank.
