I have the followingh scenario where I have a radgrid and inside it, I have a template column containing a check box:
[code]....
However, I only really want the user to be able to select one checkbox at a time.
Therefore, how to I go about ensuring that the any previous 'checks' are removed or stopping multiple checking altogether?
I have a gridview control
i add template column dynamically to gridview
like this in a function in AddColumns button clickevent
gv.Columns.Clear()
Dim chkCol As New TemplateField
chkCol.ItemStyle.Width = 20
chkCol.ItemStyle.HorizontalAlign = HorizontalAlign.Center
gv.Columns.Add(chkCol)
2)
and in row databound event i added checkbox control to this template field. like this
Protected Sub gv_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles gv.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then
Dim chkbox As New CheckBox
chkbox.ID = "chkSelect"
e.Row.Cells(0).Controls.Add(chkbox)
End If
End Sub
HERE I WANT TO GET CHEKC BOX IN btnok click event
Protected Sub btnOk_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnOk.Click
Dim linkId As String
Dim summary As String = ""
'Enumerate the GridViewRows
For index As Integer = 0 To Me.gv.Rows.Count - 1
'Programmatically access the CheckBox from the TemplateField
Dim cb As CheckBox = CType(gv.Rows(index).Cells(0).FindControl("chkSelect"), CheckBox)
If cb IsNot Nothing Then
If cb.Checked Then
linkId = Me.gv.DataKeys(index).Value
End If
End If
Next
Me.Page.Title = linkId
End Sub
But here i am not getting Check box even i used find control. how i get checkbox
I have 5 gridviews, all of of them have a Checkbox template field. I already did SUM of a specific column in the gridviews and displayed the Total in the gridview footers.
There is a submit button on the page as well.(this is not in a template column in the gridview)
what i do is select some rows in the gridviews by ticking the checkbox. Then I click on the submit button and the values change in the database and page refreshes with the new Total in the gridview footers. Any row that was ticked. the checkbox for that row in the gridview gets disabled. so cannot change the value again.
Now i want a way to show a popup with a SUM of those rows that are ticked recently and the SUM of already ticked and disabled rows before the values change for the ticked rows in the gridview when the submit button is clicked.
Is there an easy way to clear all the selected items of a checkbox list control? When a user has selected multiple items?

I have a datagrid which retrieves particular columns from an SQL database table. I also have a checkbox appended on to each row, so that selections can be made against rows of the users choice (i.e. select photos to add to favorites).
How can I code this (in VB.NET) so that these checkboxes are processed sequentially? I have heard an "array" might be best for this, but don't know how to code it. Essentially, I want the VB.NET to look through the datagrid list and to process only those rows with checkboxes checked, by applying some SQL based on these selections.
I have a gridview, in which i placed checkbox as Itemtemplate. My need is to restrict the user from selecting more than 'N' number of selections.
Eg: Gridview contains 50 records, that means 50 check boxes.
Max permitted selections: 10.
After the 10th checkbox selection, user should be prompted that..
"No more selections.. blah blah... "
Should i go for looping through records.. or is there any better way..
I am refreshing my gridview every 10 sec using update panel and Timer control.
In timer control i have:
protected void Timer1_Tick(object sender, EventArgs e){gv1.DataBind();}
Now i have a checkbox column in the gridview, and select all checkbox also, for functionality of checkboxes i am using javascript like what is explained by this article: [URL] ....
I like this way its simple and fast. but now when gridview refreshes the checkbox selection and others styles disappears.
Now what can i do to keep my selection as it is on gridview refresh. Do i have to stop the gridview refresh on checkbox selection?
This seems like it should be prettty easy - but I just can't get it to work!I have an enum in my model, which I want to display as a list of checkboxes. The user can select multiple checkboxes, and I want to save this in the database.
So the enum is like so (approx 20 elements unabridged):
public enum ReferrerType
{
[Description("No Data")]
NoData = 9999,[code]....
And it doesn't work! I guess I'm missing something obvious, but I can't work out what. There are no errors - just an empty database table where referrers should be.
How do I handle selection of multiple items with autocomplete? The objects I return from my JSON web service contain an ID and a Label - the ID is the ID of the entity in the database, and the Label is some text to display for the user.
At the moment, when I select an item in the autocomplete dropdown, the value of the item's ID is stored in a hidden field, and the label is displayed. When I remove the label, I clear the ID of the hidden field - this is done by adding an anchor element to the DOM that handles this.
Now, I want to have multiple selections. I want to be able to enter some text, get an autocomplete dropdown, select an item and some other options, then be able to click an 'Add New' button or the likes to be able to select another instance.
For example, I'd type in a person's name and get an autocomplete selection. I'd select a person, and then enter their age, and click 'Add'. The person's id, name, and age will be stored somewhere so that I can retrieve it on the server side when I post back.
I'm not quite sure how to do it? I'm thinking of a hidden field - I assume that many hidden fields of the same name/id turn up on the server side as an array, which I can then use. But I haven't tried this yet in ASP.NET.

how to change this code to multiple selections
I am trying to populate the value(s) of a listbox that has multiple selections:
Assignment Preference:<br />
<asp:ListBox ID="assignmentPreferenceList" SelectionMode="Multiple" runat="server">
<asp:ListItem Value="">None</asp:ListItem>
<asp:ListItem Value="CONTRACTING">CONTRACTING</asp:ListItem>
<asp:ListItem Value="DIRECT HIRE">DIRECT HIRE</asp:ListItem>
<asp:ListItem Value="CONTRACTING-DIRECT HIRE">CONTRACTING-DIRECT HIRE</asp:ListItem>
</asp:ListBox>
I am using a datareader in code behind to "loop" through the values:
string sql4 = "Select * from assignmentPref where tID=" + (dr["id"].ToString());
SqlCommand comm4 = new SqlCommand(sql4, con3);
SqlDataReader dr4 = comm4.ExecuteReader();
while (dr4.Read())
{
assignmentPreferenceList.SelectedValue = (dr["assignmentPref"].ToString());
}
Works great with 1 assignment preference but with 2 or 3 it craps out.
I have a requirement to allow users select multiple "Agencies" and populate the "Types" based on that selection. Cascading Drop down would have been a great fit if there is no mutliple selection involved. I am wondering if I could use a popup dropdown with chekcboxes. However, these checkboxes need to be populated dynamically by a web service. I am not very familiar with AJAX toolkit and what control would work best in this case.
View 1 RepliesI have a web form that when completed sends an e-mail with the data from the form. I have a list box that permits muptiple selections and it post to the email with the following code.
sb.Append("<br />Products of Interest:....");
for(int i = 0; i < ListBox2.Items.Count;i++)
{
if(ListBox2.Items[i].Selected)
sb.Append(ListBox2.Items[i].Text);
}
It works fine except that when multiple tiems are selected, they run together on the form. Instead of "Beds Dressers Tables", I get "BedsDressersTables".
Does anyone know if it is possible to have Cascading DropDown Lists which are based on the selected value of more than a single list. Example - I have four tables in a database as follows:
Product
PartA
PartB
PartC
The items in Product are made up by one record from each of the other three tables (PartA + PartB + PartC = Product). What I wish to do is have 3 Cascading DropDown lists which refer to the three individual parts which can be used to select items fromt he Product table.
The first two work no problem but when it comes to the third the list is condition on only items which have the selects of both the first two lists.
New at SQL and ASP.NET C#, bear with me. I have a form to insert into mulitple tables of a sql db. The form includes two listbox's, categoryIDlistbox and subcategoryIDlistbox, both with the ability to select multiple choices. Idea is that there is one record for the user created (Table1) and then that user can have multiple categories and subcategories assign to him/her in Table2
Table1:
userID
fname
lname
etc...
Table2
userID
categoryID
subcategoryID
If I understand correctly I need to use an array to take the multiple listbox items and save them to the tables. Not sure where the array goes in my code behind page to process the listbox and loop for muliplte selections. Here's my current code behind, where do I place the listbox array?

How to display checkboxes in dropdownlist ?
Actually I want to select any checkbox(For selecting months) which is listed in dropdownlist?
Using SQL Server 2008, C#, .Net 3.5
I have two tables - Reports, Usage
Report table:
RId
RName
RGroup
Usage table:
UId
UUser
What I want to do is make a page that will list all the reports in the Reports table and have a checkbox next to each name. A user can check each report they use and when they click "submit" it will insert each ReportID into the Usage table.I'm guessing that I should use a GridView to display all the Reports?How would I make it so that the "submit" button would insert each "checked" record into the Usage table?
I'm storing details about clothing in a database, and I need to save multiple entries for colour. For example, a user selects a top, and then needs to select the colours red, black, white and blue from say a group of tick boxes. How should I store this infomation, and what web controls would I use to help the user make there selection?
View 10 Repliesthe form has 15 items to choose with radio buttons, any number can be selected. I would like to process them as a 'group' so I can do something like loop thru them, checking if each one has been selected to build a list and also be saving them to a table row, etc but it seems all the designations as a list or group make it mutually exclusive. just looking for better coding than checking them with an if statement or similar so the question is if there is some way to designate the radio buttons as a group but no force the group to be mutually exclusive
View 4 RepliesI have a list box that allows for multiple selections (holding down the control key) the selection quantity is basically unlimited, but realistically should never be more than 50 to 100 items from the listing of about 3000 items.
I need to collect the list of selected items from the drop down list and retrieve each of their full records from the item master and populate a gridview.

I could really use some building the SQL statement to select the choosen record data. I think I have the selection list worked out by populating an array but I am not clear on how to build the SQL query.
My question is I have multiple Checkbox Lists and i want to compare it and Filter Datalist records on Checkbox list checked event.. (I want filtering something like [URL]

I am dynamically binding a typed list to a GridView control.
The Grid View Control is in an asp.net page that is wrapped in an asp:UpdatePanel (Ajax).
The first column contains a checkbox control.
Only one checkbox may be checked in this column.
If the user checks a checkbox, all other checkbox must be unchecked.
I am trying to achieve this using client-side script without success.
In the handler for the GridView's RowDatabound event, have attempted to add an attribute to the CheckBox contained within the cell.
