I have able to generate several labels and textboxes based on a table in the database during runtime. My problem is that I could not get these values from these textboxes whenever a user changes these values and update them.

View 4 RepliesI have a repeater which is binded using a Collection of Entity Data Framework.
Once the repeater is binded using the datasource, the user can control the no of rows present in the repeater using a Dropdown list on the page. For ex: if datasource has 2 rows, user want to add 3 more rows, user selects 5 from dropdown, which adds 3 additional rows to the Repeater. I am able to do this.
The repeater has textbox controls in each row. Now once the user enter the values in this textbox of the newly generated rows, the user can save the values entered with the no of rows specified.
I have a button which is outside the repeater and on click of this i need to validate all the textbox values and save them into dB accordingly.
Here is my code
Repeater.aspx

I have created a page with a textbox and a button, when you enter a number in textbox and click on button, the onCommand event generates dynamic textboxes with dynamic requiredFieldValidators in the placeHolder and a newbutton. Now when I click on newButton, it does not validated dynamically generated textboxes, it does postback and every dynamic object disappear. The sample code is provided below.

I have to show runtime genrated image on a View in ASP.NET MVC web application. how should i render this image.
I am using asp.net MVC 1.0 . how can show runtime generated image to user.
I have code that another member assisted with and is working great. Now that the page is working more and more like it should with the remaining requirments. I have something else i would like to implement.
Since the code i have automatically creates / generates a table with textboxes and labels based on a drop down selection. I would like to know how to clear the textboxes if they chose 0 from the dropdown. Or if they select "No" on the radiobutton, then that means they have nothing to provide, so i dont want to capture something that they may have entered before changing their mind.
Here is the code the generates the tables and textboxes, i just need to setup, so that if they select "NO" from the radiobutton or if they select "0" from the dropdown that the textbox values, if any, are cleared so that we dont get inconsistant data captured.

how to populate textboxes during runtime in c#.net..
View 3 RepliesI have a DataTable where the columns are generated programmatically at runtime. I then bind this DataTable to a GridView. What I'm wondering is how I can create the GridView to accommodate this, and if it's not possible, how I can output the DataTable into nicely formatted HTML.
View 3 RepliesI have a Winforms app which provides the ability for users to create their own reports. At its simplest they design the query which gets encrypted and saved into a database.
The ability to view these reports via the web as now come upon us.
What is the best way to handle this? Ideally I want to use MVC but there will be no model or viewmodel because these queries can return data for any table across the application and so I cannot have hardcoded propeties etc. Obviously I have access to the SQL to execute it.
I wonder if tradtional ASP.Net may perform better in this scenario ie/execute the SQL and put it in a DataTable but was hoping to get some thoughts from the community.
Problem for me is that a tag is being generated that apparently just moves the treview a little bit. So I am thinking I should delete it at runtime. How do I do that?

I am generating dynamic textboxes with the ids as follows table row 1:
no1,name1,addressline11,addressline21,city,pin,communicationAddress1(here the row count I am appending at last to the control id's)table row 2: no2,name2,addressline12,addressline22,city,pin,communicationaddress2
table row 3: no3,name3,addressline13,addressline23,city,pin,communicationaddress3 and so on....
A new will be created when user hits enter key in the last textbox i.e., communicationaddress.For validations I have used java script. Now my requirement is when user types the address line the content of the textbox should be copied to communication address.
communication address = addressline1+addressline2+city+pin
so in theabove four textboxes when the user hits the keys the matter appending to the communication address with ',' seperated. I acheived this through key press event in java script..................
I'm trying to make a form that could have one or multiple textboxes. I have a textbox and a button to add additional textboxes.
I have no problem adding a second textbox inside a panel but I want to be able to keep adding more textboxes every time the link button is clicked and later reference those boxes to be saved. I would also like to maintain the value of the textboxes there. They are not saved to the database until all the necesary texboxes have been added.
I added the textbox using:
private void button1_Click(Object sender, System.EventArgs e)
{
TextBox textbox1 = new TextBox();
panel.controls.add(textbox1);
}
that works fine, but when i click the button again it doesn't add an additional textbox which is what i need.
i have a textbox (txt_inputchild) for entering no of children name.
and a Add button (btn_add) for increasing the no of children one by one.
how to write code in c# and how can i identify my dynamic textboxes id's to send data to database.
how do I do the most simplest thing like get the values from textboxes in a form and bind them to my lets say product or whatever object?
I work with MVC 2 and NHibernate. I seen some examples where they work with linq 2 sql and what they do is just save the product in the controller like _repository.Save(product);
they use active record and is that why that is possible? And in this example they use on the beginform like this

I'm trying to call a Soap Web Service, and I need to pass an Address Object to the Server. I can pass an existing address.Id to update an existing address, or if I leave the address.Id empty, it should be saved as a new Address. The Problem is that the Id is of long type, and it allways has a value of 0.And this makes problems for the server, because even if the Id=0, the Server Side function will take the Address as Existing one, and it will start to search on the Database for an Address with Id=0. Of course there is no such address, and it throws an error. When I try to call the Web Service with WebService Studio or SoapUI, and I delete the id manually, then It works as expected, as soon as I put <address id="0"> then it returns me an error - Address with Id=0 not found.So the question is, how to change the webservice definitions, or the proxy classes so that it does not generates this id="0" at all?P.S. I cannot change the Server Side method, it would have been the easiest solution, but unfortunatelly is not possible.
View 1 RepliesI setup custom CSS class for array of dynamic TextBoxes (inputs as HTML)so... now I need to get array of it :
<input type="text" style="width: 50px;" class="DynamicTB" id="ctl00_ContentPlaceHolder1_GridView1_ctl02_id" readonly="readonly" value="1" name="ctl00$ContentPlaceHolder1$GridView1$ctl02$id">
sure client don't really knows the count of inputs. That's why I use class and here is what I'm trying to make :
$.each( { id : $("input.DynamicTB").css("value") },
function(id){
CallPageMethod("SelectBook", success, fail, "id",id);

I have implemented a user control with dropdown lists and textboxes where user may choose to add more of the same user control dynamically then submit the values within all usercontrols at the same time. They way I added usercontrols dynamically is whenever user clicks "add more" button, it increases the value of "userControlAmount" in session by 1, reloads the page and during next page_load event, within an updatepanel it creates usercontrols on the fly.
However whenever more is added since all usercontrols are generated again according to the latest user control counter, the values within the dropdownlists and textboxes are getting reseted.
I can hold all values in a viewstate/session however beyond the time/effort it will take, it doesn't sounds very "professional" to me. I was wondering if there is a more efficient way of doing this.
I currently have an accordion and I want each accordion to populate only if the user clicks on that header( partial accordion rendering ). How are people doing that nowadays? I know I can do it with updatepanels but have read bad things about update panels. Also just as an FYI each accrordion panel content pane will look the same ..It will have a thumbnail of the product..several checkboxes and a download button . The values or names of the checkboxes need to be generated so that I can then grab them and lookup those values in an xml file to find the location and then zip those files up and have user download it..I actually have all this working with all the content of the accordion being generated on server at load time but being that I'm trying to learn asp.net I figured I would give partial rendering a shot..I like the idea of only loading content for that accordion panel if user is interested in in. I also have a webservice running which displays hello world in the accordion panel content that trigger the network callback..That's fine but then I'm thinking ok now how do I build the checkboxes and html that I really need to send back and is this web service the correct solution. Another thought is using javascript to create elements as the data is retrieived from the web service..I'm just trying to do it the right way[URL]
View 4 RepliesI have a table in the database for users with the columns FirstName, LastName, DateUpdated, UserUpdated. Now, I display the fields FirstName and LastName but the last to fields are just for internal record keeping. I don't want the user to see or be able to edit them. However, I do want the DateUpdated and UserUpdated field to be populated upon every insert and update. The user id is in the session and I just take the current date for the DateUpdated field.
My question is: How can I write the UserUpdated and DateUpdated fields without the user providing any values?I had a couple of ideas:
- Modify the DataContext class to automatically compute the values. Don't know if that's a good idea. Also, my changes will be overwritten when I re-generate the DataContext class.
- Create hidden fields that hold these vlaues. For instance: <asp:HiddenField ID="user_createdHiddenField" Value='<%# Eval("UserUpdated") %>' runat="server" />. But how do I actually assign a value to the field?
I have some logic that loops and adds a new Panel control to another control:
for (int segmentIndex = 0; segmentIndex < segments.Length; ++segmentIndex)
{
holder.Controls.Add(new Panel() { Width = Unit.Percentage(segments[segmentIndex] / segmentsSum * 100), CssClass = String.Format("segment segment-{0}", segmentIndex) });
}
container.Controls.Add(holder);
This works great, but there are a few values that I need to store on each panel within the loop. I need to be able to access these values in both c# and javascript, once the control is rendered on the page. What would be the best way to achieve this? I've used the Tag property before on some controls, but a Panel doesn't have one.
Is it possible to add values in textboxes as well as subtract values? Scenario:

I am using this code which works perfect when I type username and the studentid in my textboxes in the first page.Now after pressing the button to go to the second page , the two labels display the values of the textboxes in the first page BUT when I am pressing a button in my second page I get this error :
Object reference not set to an instance of an object.
My code which is in the second page load event is :
Label1.Text = "Name:" + CType(PreviousPage.FindControl("txtusername"), TextBox).Text
Label2.Text = "Student ID:" + CType(PreviousPage.FindControl("txtstudentid"), TextBox).Text
Is there any option to make this labels keep their values ??
