I'm trying to build a list of checkboxes, each one with a textbox/textarea associated to it. The plan is for it to look something like this
[checkbox]
[textbox]
[checkbox]
[textbox]
[checkbox]
[textbox]
The title of each checkbox & textbox will be populated from the database. I'm not really sure how to go about doing this.
I want to create List of Grouped Checkboxes as follows:
[]Group1
[] Item1
[] Item2
[]Group2
[]Item1
[]Item2
[]Item3
Here Group# and item# are checkboxes. Does anyone know how to do this in asp.net. I am getting data from DataSet. One limitation is that I am not allowed to use third party tool/controls or jQuery.
I'm fairly new to MVC and have an issue converting something I created using normal ASP.NET to MVC framework.I have a database with one to many relationship between 2 tables. I need to be able to make amendments to the single parent row in the same page as that which will edit the many records. The values to be edited in the table with many rows to be edited are either true or false and will be edited using a checkbox.
To make it a little more complicated the list of checkboxes is actually dynamic and is built from another table.In the normal ASP.NET page, all the controls are placed in a details view and the dynamic list of checkboxes is added to a placeholder on Page_Load. Then I get the list of values that are true and, for each row in the list, use FindControl to find the checkbox with the appropriate ID and set it to flagged.
I've got the MVC page working so far as follows:
I can build the checkboxes I need by passing the list of ID's using the ViewData.
I can also add, and edit the fields that are in the table with the single row that needs to be edited.
What I'm stuck on is:
Populating the appropriate checkboxes with "true" as appropriate
Subsequently saving any updates to the checkboxes when the save button is clicked.
i want to insert checkbox text only if they are checked. .. how to do that ..
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
TextBox1.Text = Request.QueryString("txt")
Dim splitted As String() = TextBox1.Text.Split(",")
For Each id As String In splitted
Dim ctrl As Control = Page.FindControl("checkbox" & id)
If Not ctrl Is Nothing Then
Dim chkbox As CheckBox = DirectCast(ctrl, CheckBox)
chkbox.Enabled = False
Dim arrList As New ArrayList()
'populate the list with some temp values
arrList.Add(CheckBox1.Text)
arrList.Add(CheckBox2.Text)
'databind the list to our repeater
Repeater1.DataSource = arrList
Repeater1.DataBind()
End If
Next
End Sub
This code will add all checkboxes whether it is checked or not !
so that only checked checkboxes would be added in array list
I have a table that get populated via an external text file. I am not sure of the exact process as I'm relatively new to the company.
The table does not have a primary key as the entire table is dumped and re-loaded every quarter when there is a new text file.
Enter ASP.NET MVC. I need to display that table with checkboxes in a grid so the user can select some rows and send it back to the server. It sounds relatively easy, but I am really not sure what to put as the value for the checkboxes as I am pretty sure I'll need to use multiple columns to create a unique. Yep, I know, I know :).
OldTable
- Field1
- Field2
- Field3
...
- FieldN
The View
...
<input type="checkbox"
name="bunchOfStuff"
value"Field1Value,Field2Value,Field3Value"/>
...
Would something like this work? If I can create a key with a few fields, can I use those fields as the value in the checkbox? I realize my action will be a bit ugly as I'll have to split and parse each value in the array of values.
I got a list of customers I thought I would list in a gridview or a repeater with customer html, it gone have paging. I'm gone have a checkbox for each customer in the list. Do you guys have any suggestions on how I should do to keep the checkbox value when I go to page 2-3-4 ect in the paging. I'm thinking a session to store the id of the checked customers. After I'm done setting the values they go to the database.
Do you got any other ideas then the session I'm thinking of?

What I want is when a user fills out one or multiple fields on the form, how do I display data in the gridview on the click of SEARCH button? Also is it necessary to write a codebehind for my search button or we can achieve the desired result in some other way?

I'd like the items to appear in the textbox as x, y, z, or x y z. The seperator type / format isn't important as long as long as there is some sort of spacing between each item.

View 1 RepliesI have a textbox control and a checkbox list control on my page.
I am first populating my checkbox list with a list of employee objects in the code-behind. An employee has an id and a name. Both are displayed in the checkbox list like so:
Jim (1)
Alex (2)
Gary (3)
When a user checks one of the boxes, the employee's name needs to be populated in the textbox. So if Jim is selected, the textbox value is "Jim". It also needs to support multiple values, so if Jim and Gary are selected, the textbox value is "Jim, Gary".
Also, if a user enters a valid value in the textbox, the correct employee should be checked. This needs to support names and id's. So if I enter "1,Alex" in the textbox and then click outside the textbox, Jim and Alex should be selected.
I'm using ASP.NET and I need to do this using AJAX, but I have no experience with using jQuery and AJAX. Could someone show me a simple example of how to do this?
I'm having some difficulty adding an autocomplete extender to a textbox and getting it working.
I've read through the samples and did a quick search on here, but cannot work out why it isn't working.
In a nutshell...
I've added a textbox onto a page, and added the autocomplete extender along with the AutoComplete page method.
Page
[Code]....
Code Behind
[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
public string[] GetCompletionList(string prefixText, int count, string contextKey)
{
StaffADBLL staff = new StaffADBLL();
DataTable dtStaff = staff.FindStaff(prefixText);
string[] items = new string[dtStaff.Rows.Count];
int i = 0;
foreach (DataRow row in dtStaff.Rows)
{
items.SetValue(row["displayName"].ToString(), i);
i++;
}
return items;
}
I've even tried adding an asmx file, and that doesn't work either.
I get no errors and when I start typing nothing happens, it doesn't even produce a list after 3 characters.
I tried to debug and it doesn't debug through the code, skips it completely.
radiobuttonlist (Yes and No)
if yes, textbox should be visible
could we do it using ajax and without using autopostback property?
We have a page with quite a few textboxes and a dropdown list at the end. The dropdown list at the end is a "Result" and dependant on the result certain textboxes need to be filled in and this needs to be checked when they submit the page. I was thinking of using a custom validator
