View 1 RepliesDoes anyone know how to pass values from adynamically created gridview checkboxes to a crystal report?Is it possible? I am using asp.net, vb.net and mssql. Here's my grid minus a few boundfields:
<asp:gridview id="grid" runat="server" autogeneratecolumns="False" cellpadding="4"
forecolor="#333333" gridlines="None" emptydatatext="No Products registered for this company...">

I want to add two checkboxes to selected days in a calendar control. I can do that but I can not figure out how to get the checkboxes to fire an event. I tried to get a button to fire and event by iterating through the panel without success either. Here is my code so far:
Photon (Springfield, Missouri)
<%@ Page Title="" Language="VB" MasterPageFile="~/Default.master" AutoEventWireup="false" CodeFile="Caledar_Add.aspx.vb" Inherits="Admin_Caledar_Add" %>

How can i put Checkboxes at the end of the node of treeview dynamically. My treeview is dynamically generated.
View 1 RepliesI´m developing a database driven asp.net 4.0 application and are currently stuck with the following issue.
I need to dynamically add checkboxes using code behind. These checkboxes represent activities that the user may chose from by ticking the ones that they are interested in. I do not know the number or which activities that should be presented until runtime so hard coding checkboxes is not an option.
On the client side I need to keep track of which checkboxes/activities the user have chosen as I need to calculate the cost for these without doing a postback. I would like to use javascript to find out what activities that are chosen and also calculate the total cost using javascript.
To implement this I tried to use Page.ClientScript.RegisterExpandoAttribute (server side) and javascript (client side, but I do not manage as ticking any of the checkboxes will not fire a client side event. I´m also using Telerik RadPanelBar controler.
Below is my current not working implementation:
Code behind/aspx.cs
public override void DoLayout(Aranea.Common.EntityDOL.ProjectRegistration existingRegistration)
{
base.DoLayout(existingRegistration);
lblCaption.Text = "Payment page";
//Get collection
TrackableCollection<ProjectActivityBooking> acitivities = existingRegistration.ProjectParticipant.ProjectEntity.ProjectActivityBooking;
//Add datasource and bind
this.RadPanelBar1.ItemDataBound += new RadPanelBarEventHandler(itemDatabound);
this.RadPanelBar1.DataSource = acitivities;
this.RadPanelBar1.DataBind();
this.lblTotalBooked.Text = "Total Booked " + decimal.Round(totalBooked, 2).ToString();
}
void itemDatabound(Object sender, RadPanelBarEventArgs e)
{
decimal totalActivityPrice = 0;
//Get panelItem
RadPanelItem item = (RadPanelItem)e.Item;
//Create Checkbox
CheckBox chk = new CheckBox();
chk.ID = "box";
//create label
Label lbl = new Label();
//Get Activity
ProjectActivityBooking activity = item.DataItem as ProjectActivityBooking;
//trying to register my checkboxes
Page.ClientScript.RegisterExpandoAttribute(this.validator.ClientID, "ClientID", chk.ClientID);
//Get total activity price
totalActivityPrice = GetActivityPrice(activity);
//Get total booked
totalBooked += totalActivityPrice;
lbl.Text = totalActivityPrice.ToString();
//Set activity name
chk.Text = activity.ProjectActivity.ActivityName;
chk.TextAlign = TextAlign.Left;
//Add controls
item.Controls.Add(chk);
}
Client side code:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="PaymentPage.ascx.cs" Inherits="CX.Aranea.Client.WebFront.UserControls.RegistrationForm.Payment.PaymentPage" %>
<%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>

I´ve been stuck with this for some time now and have a nice deadline coming up :) I would be most thankfull if anyone could point me in the correct direction as I feel a bit clueless. Perhaps there is a much easier way of solving this? Perhaps my code is all wrong?
I am new to asp.net. I am trying to display some data from a database table using dynamic table in my page. I want to add checkboxes to a field in the database and would like to perform several tasks based on the values checked. The checkboxes are tied with the primary key field of the database. Here is the code snipet :
[Code]....
Now I have a button in my page. The functioanlity which I desire is on clicking that button I should be able to extract the values of checked checkboxes and perform some function.
I've dynamically created 3 checkboxes as you can see in the code below. I also wrote an event handler below. When I run the code, the 3 checkboxes show up, but the event handling does not work right. Whenever there is postback from any of the 3 checkboxes, Label1 reflects the state of checkbox #3, no matter if I toggle checkbox #1 or #2. I put the code I have under Page_Init into Page_Load instead, but makes no difference either way.
The bottom line is, I want the event handler to know exactly which of the 3 checkboxes is firing the event so that Label1 can reflect that.
[Code]....
I am dynamically adding the checkboxes in calender DayRender event. i need to read them on some other button click event on webpage.I need to read the checked checkboxes.
View 7 RepliesI'm trying to check dynamically generated "checkbox" value inside Listview.
I can reference non-dynamic checkboxes exact in same location (index) inside Listview using "e.Item.FindControl", however I can't reference dynamic checkboxes.

asp.net using visual studio 2008 3.5 framework with sqlserver 2008. I have a webform (derived from master page) so its a content form with content placeholder. It has two text boxes, dynamically populated checkboxes from database and 8 radio button groups. It has two custom validators attached with two of my fields also. I've tried every way to clear my form but its not working somehow. I've tried Control iteration method. Ive tried btnReset.Attributes.Add("onClick","document.forms[0].reset();return false;"); thingy...but none is working.
View 4 RepliesI have 50 checkboxes that I need to write onto an aspx page. Each checkbox comes with 3 textboxes.
Example:
chkbox State Name donation new donation
chkbox CA Sam 10 15
chkbox AK Sam 15 20
Now this shall go for all 50 states, depending on which states the person wishes to donate. In each state's row shall be a checkbox. So initially the page shall have value 0.00 in donation and new donation checkboxes, but all 50 states shall be visible. When the person puts a value of donation in certain state, that state shall get "checked" value and the donation, after submitting. On reloading, the value shall be populated automatically and checkbox checked automatically.
How do I make these 50 checkboxes in VB.NET? Do I have to write the table in .aspx with 50 <tr> tags, and then have VB.NET code populate it? Can I otherwise dynamically write these checkboxes from VB.NET code?
I'm trying to create checkboxes inside Listview from code behind, but I'm having problem creating them.
What am I missing here?
Checkbox's ID comes from Datareader.
Here is my code.
If reader2.HasRows Then
While reader2.Read
Dim jobid As String = Convert.ToString(reader2("JobTicketID"))
Dim jobtitle As String = Convert.ToString(reader2("JobNickName"))
Dim item As ListViewDataItem
For Each item In ListView1.Items
Dim jobtd As HtmlTableCell = CType(item.FindControl("jobtd"), HtmlTableCell)
Dim jobtr As HtmlTableRow = CType(item.FindControl("jobtr"), HtmlTableRow)
Dim cb2 As CheckBox = New CheckBox
cb2.ID = jobid + "cb2"
cb2.Text = jobid + IIf(jobtitle <> "", " (" + jobtitle + ")", "")
jobtd.Controls.Add(cb2)
jobtr.Visible = True
Next
End While
End If
I have a table witch i programmatically fill with(multiple) IDs in the first column, options in the second and checkboxes in the third. The table is in a View as it is part of a wizard and is filled on view_Activate.
How can i get the checked property of the checkboxes when i pass to the next view? When i try to do that on view_Deactivate the table is already 0 rows...
I know i can use i checkboxlist(... whose properties i can get on view_Deactivate) but i'd rather use a table as it is easier to layout as i want it(header, columns, alignment,...).
I´m using a Repeater to generate Items out of a Database. Each ReapeaterItem should include an UpdatePanel, because i have to Update the Controls inside the UpdatePanel and do not want to reload the complete page. Inside these dynamically generated UpdatePanels (each RepeaterItem has one) i´m adding up to three Checkboxes dynamically (based on the Database). These Checkboxes need to fire the "CheckedChanged" event, because on some conditions i want to enable/disable/check/uncheck Checkbox1, 2 or 3 based on business logic. ... Hope you got this so far. I´m adding all Controls and have the EventHandler Added. But the generated Code does not reflect the Event Handler. I tried OnItemDataBound, OnItemCreated, PreRender, ... Events to add the Eventhandler too, but i was not able to find the CheckBox-Control with the ID.
I´m totally lost with this and on the way to use Buttons instead of Checkboxes. From what i read so far is that with Buttons i can use the CommandName from the Button and the ItemCommand-Event from the Repeater to get a workaround, but then i need to reflect the "Check" on the Page in some way. btw, every Repeater (8) sits inside an ajaxtoolkit-accordion control. Here i give you some Code:
aspx-Page
<asp:Repeater ID="RepeaterAccordionPane2" runat="server">
<ItemTemplate>
HTML Stuff<%# DataBinder.Eval(Container.DataItem, "Header")%>HTML Stuff<%# DataBinder.Eval(Container.DataItem, "Beschreibung")%></td>
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode=Conditional>
<ContentTemplate>
</ContentTemplate>
</asp:UpdatePanel>
HTML Stuff
</ItemTemplate>
</asp:Repeater>
Here is the Page_Load Part
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
dvAlleArtikel = new System.Data.DataView(...Database...);
[... some other code here ...]
RepeaterAccordionPane2.DataSource = dvAlleArtikel;
//RepeaterAccordionPane2.ItemCreated +=new RepeaterItemEventHandler(RepeaterAccordionPane2_ItemCreated);
//RepeaterAccordionPane2.PreRender +=new EventHandler(RepeaterAccordionPane2_PreRender);
RepeaterAccordionPane2.DataBind();
int nUpdatePanelIndex = 0;

I am tring to bind the gridview with check box dynamically but the grid view shows only 36 check box.But in the database there are above 36, Why it did not showing the remaining checkbox , When binding the gridview the dataset is having only 36 check boxes. i can't able to understand where the problems occur,
View 2 Replieshave a gridview with a bunch of checkboxes. I would like to restrict the selection based on a value I get back from the database. I am able to do this on the serverside but it is very cluncky. Is there a way I could do that using javascript and ajax or just a more elegant way to approach this. The gridview is in a usercontrolMy code right now -

My selectioncount code is as follows - Protected Sub selectionCount(ByVal sender As Object, ByVal e As EventArgs)
I am running into a problem getting a value from my Grid View based on the selected checkbox. I have a grid view that is populated by database based on search criteria. However once that Grid View is populated, I would like to be able to select multiple ID's from that view. My coding experience isnt the greatest as I am still fairly new to all of this.
<asp:GridView ID="GridView1" runat="server" DataSourceID="ObjectDataSource1"
I am trying to implement a gridview with some checkboxes to allow users to select the rows that they would like to insert into a file selected from a dropdown list. am working on being able to select the rows from the grid but not having much success. I can get it to recognise each selected row but when I place them in a dataset it only stores the last checked gridrow. It's probably something simple that I'm missing y code is
protected
void Insert_ButtonClick(object
sender, EventArgs e)

I hav a prob of checkboxes' checks not being registered...as explained below :
I have a gridview which is being populated using datasets.
[Code]....
I have added a column of checkboxes it using a TemplateField
[Code]....
And I am using a button to count the number of checked checkboxes.
[Code]....
I am viewing the value of session variable under at check.aspx
The Problem is that no matter how many checkboxes I check they are always counted as 0. The 'check' just doesnt get regsitered in the gridview.
After quite certain testing, a few things are clear
The checkboxes are being discovered by the counting loop fine.If I mark a cell as checked in the dataset before binding, then that check does get registered and thus is counted. Any thing I am missing ? Do i have to update something ?
Im trying to input the value in the table into the checkboxes but i keep getting an error that states: "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index"When i do a quick on this part of the code :"DirectCast(GridView1.Rows(i).FindControl("DescriptionA1"), Label).Text", i get "Run-time exception thrown". This is my first time trying something like that, i have search for solutions but now im more confused than ever.

save the Mulitple checkboxes in Gridview in once. I want to save only those rows which are checked.. not the once which are not checked. There is a row in gridview which has four checkboxes in each row, so i want to save the row in which either or all of the checkboxes are checked and ignore the once in which anyof checkbox is not checked.
View 4 RepliesI need to check if ANY of the checkboxes are selected from the gridview.. if atleast 1 is selected, then continue, if none are checked then return the error message so they can make a selection, below is what i have.. if i have all checkboxes checked, then everything works, but if i only have 1 then it doesnt work..

when i checked the checkboxes(not all) ,corresponding rows data has to be updating when i click save button which is outside of gridview,Its just same like our gmail delete button.
I have situation where I have to show checked CheckBox in a GridView. I have three tables
1) Menu Items ( Fields: menuID, menuName, menuLink, .....)
2) User Types (Fields: userTypeID, userTypeName, ...)
3) User Menus (Field: menuID, userTypeID )
I have a screen to add new Menu Items where I am showing a Grid That has two columns
1) CheckBox and
2) User Type
I have to check CheckBox in order to Link that User Type with the Menu Itme. I am done with Add Screen. Here is the Code:
(aspx)
<asp:GridView
ID="gridView_UserTypes"
runat="server"
AutoGenerateColumns="False"
DataKeyNames="userTypeID"
Width="60%"
EmptyDataText="">
<HeaderStyle
CssClass="gridHeader"
Wrap="false"
/>
<AlternatingRowStyle
CssClass="gridAlturnateRow"
/>
<RowStyle
CssClass="gridRow"
/>
<Columns>
<asp:CheckBoxField
DataField="userTypeChecked"
HeaderText="Select"
ReadOnly="false"
Visible="true"
/>
<asp:TemplateField
HeaderText="Select">
<ItemTemplate>
<asp:CheckBox
ID="userTypeSelector"
runat="server"
/>
</ItemTemplate>
<ItemStyle
HorizontalAlign="Center"></ItemStyle>
</asp:TemplateField>
<asp:BoundField
ItemStyle-HorizontalAlign="Left"
DataField="userTypeName"
HeaderText="User Types"
HeaderStyle-Wrap="false"
ReadOnly="True"
SortExpression="userTypeID">
<ItemStyle
HorizontalAlign="Left"></ItemStyle>
</asp:BoundField>
</Columns>
</asp:GridView>
(Code Behind)
foreach (GridViewRow row in gridView_UserTypes.Rows)
{
// Access the CheckBox
CheckBox cb = (CheckBox)row.FindControl("userTypeSelector");
if (cb != null && cb.Checked)
{
// First, get the UserTypeID for the selected row
int userTypeID = Convert.ToInt32(gridView_UserTypes.DataKeys[row.RowIndex].Value);
if (selectedUserTypeIDs == "")
{
selectedUserTypeIDs = userTypeID.ToString();
}
else
{
selectedUserTypeIDs = selectedUserTypeIDs + "," + userTypeID.ToString();
}
userTypeCount++;
}
}
Now I am passing selectedUserTypeIDs along with other details to my Stored Procedure and adding those UserTypes for newly Added menu. It works fine for me. Now I want to show checked CheckBox in Edit Mode.
