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.
[Code]....
I use if(! Page.postback) to fill those two repeaters I want to get the data related to checked checkboxes when using the below code it get only the data of the first checked box how to make it brign all the data
private void Btn_Confirm_Click(object sender, System.EventArgs e)
{
//CheckBox checkedButton = null;
foreach (RepeaterItem item in ParentRepeater.Items)
{
CheckBox control=(CheckBox)item.FindControl("CheckBox1");
if (control.Checked)
{
//checkedButton = control;
foreach(DataRow r in GetInnerData(control.Text).Rows ) // GetInnerData is used to pring datarelated to the selected check box
{
if(r["DESCRIPTION"].ToString() == control.Text)
{
Response.Write(r["DESCRIPTION"].ToString() + r["Date" ].ToString() + r[ "Trx" ].ToString() + r[ "GL" ].ToString() + r["Amount" ].ToString() +"
");
}
}
control.Dispose();
//checkedButton.Dispose();
break;
}
}
}
}

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'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?
I'm having a bit of a problem with this code.
The program gives me a list of checkboxes but a user ID. then u user can change his selection and push the save button (id="btnSaveUserIntersts") and i am trying to save in the hidden textbox all the values of the checkboxes that was choosen.
The problem is that i am getting all the time the same selections that came form the database and not getting the new selection that the user made.
what am i doing wrong here?

I have a listview with a nested gridview. I'm having trouble accessing the gridview. I want the gridview to be filled and displayed when a linkbutton is clicked on the listview. I use FindControl to get linkbutton - but cannot get it to work for the nested gridview. I have gridview working outside the listview, but it fails when nested.

asp.net Code:

I have a list box in a list view control. I want to access the value of the listbox. I have fixed the height of the list box and the box has scroll bars. If i change the number using the scrollbar and then click on the number (turning it blue) everthing works fine. If I simply change the number using the scrollbar the system throws the error below. Can anyone tell me how to get this to work simply by using the scrollbar to select the number (without having to also click on the number itself) This is the error that is thrown

I need to bind a List control based on the Gridview Row's datakeyName value while the Gridview control is being loaded into the page. I tried the following but it does not work.The BulletedList control is nested inside a Gridview Control and they both bound to an ObjectDataSource control. In my code, I passed teh UserID into the UserID parameter and call the Select() method but still does not work. Basically, I want to list of a user's hobbies, therefore the hobbies control are driven by the userID. tell me how can I get it to work?

Nested Repeater Issue: Each category list gets populated with the same set of date values rather then being populated with the data associated with that category. Trying to Do: Trying to group FAQ's by category and then list them using the repeaters.
The data is queryed though a business logic layer object that makes a call to the data access layer object. The data access layer object uses linq to sql to return data. There are 3 parameters that are passed into the innerDataSource's ObjectDataSource control to populate the nested repeater control (propID, CatID, isVisible).
With the debugger, the correct data is being returned and written to the nested repeater firing from the nested repeater's ItemDataBound event. Once this event is finished, another event fires and runs the FAQRule object again on the business logic layer which re-populates the nested repeater with the same data for each category. I have 2 repeaters, outerRepater (parent) and innerRepeater(child) with 2 ObjectDataSource controls innerDataSource and outerDataSource. See code below : ASP Page:
<asp:Repeater DataSourceID="outterDataSource" EnableViewState="false" runat="server">
<ItemTemplate>
<%# Eval("Description") + " " + this.Property.PropertyName %>
<asp:Repeater EnableViewState="false" runat="server" DataSourceID="innerDataSource">
<HeaderTemplate>
<ul style="width: 500px">
</HeaderTemplate>
<ItemTemplate>
<div><%# Eval("Question") %></div>
<div><p><%# Eval("Answer") %></p></div>
</ItemTemplate>
<FooterTemplate>
</ul>
</FooterTemplate>

I have the following class:
public class MySeat
{
public string Section { get; set; }
public string Row { get; set; }
public string Seat {get; set; }
}
I want to group a list of seats by the Section and Row so that I can make a comma seperated list of the seats.
var groupedSeats = seats.GroupBy(x => new { x.Section, x.Row });
foreach (var group in groupedSeats)
{
htmlWriter.Write(group.Key.Section);
List<string> seatNumbers = new List<string>();
foreach (var seat in group)
seatNumbers.Add(seat.Seat);
htmlWriter.Write(string.Join(@", ", seatNumbers.ToArray()));
}
Is there a better way to do this with LINQ? This is just a small portion of the code I'm trying to clean up, I'm curious if there is a better way to grab the seat numbers for display rather than creating a list, looping through the groups and then doing a string.Join on it.
I've got a LINQ to SQL object, and I want to group the selected data and then pass it into a view. What's the correct way of doing this? I'm sure I need to group the data when I select it rather than grouping it in the view, as this will result in about 200 rather 50000 rows I need to pass into my view. Are there any good examples of this online that anyone has seen?
