i'm using a gridview and has a column of checkbox that is within a template field.
I want to do it in C# but I only found this code in VB
[Code]....
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.
I have a GridView with checkboxes. I want to let the user choose one or several checkboxes. Right now my code only manages to find one of the chosen checkboxes:

This morning I posted a question w.r.t Radio Buttons, but the requirement changed so I'm posing a similar question.
I want to have a checkbox in a datagrid.
Suppose I click on one of the checkboxes and then realize i need to click on another, the screen has to automatically uncheck the previously clicked checkbox and then check the newly clicked checkbox.
In other words I need to clear previously checked checkboxes and check the recently clicked checkbox.
Also, I need to update a label in the page with a value associated with the row of the checked checkbox.
I should not be using a javascript to do this.

how can i checked the checkbox in parentGridview whenever i checked a checkbox in childGridview?
View 1 RepliesI 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 am working on a datagrid that has a column with checkboxes... the checkboxes should be checked when the page loaded. The problem is that whenever I trigger a postback, all the checkboxes will be unchecked!!
I don't know what is causing this or what should I do to prevent it from unchecking the checkboxes.
I have many country check boxes on page and i want to search data from database based on check boxes checked i.e. user can check check single or multiple checkboxes. So how can i fetch the data/records from database based on same.
View 1 RepliesI have a page that im using javascript to do a select all / unselect all for my checkboxes on the page. Now i need to determine in the code behind if all of them are checked, im wondering if it would be easier to just set a session or something whenthe select all is checked, but that wouldnt be accurate, because after you select all, you still can uncheck some..
So i need it to check at the time the button is clicked.. there are currectly 30 checkboxes, NOT a checkboxlist.
I tried using the site search but getting an error has occured when i click to search..
I have a checkboxlist control in ASP.NET
<asp:CheckBoxList ID="chkchrges" runat="server">
</asp:CheckBoxList>
I am binding in following way
chkchrges.DataSource = objclsChargeMaster
chkchrges.DataTextField = "chrgdcd"
chkchrges.DataValueField = "chrgcd"
chkchrges.DataBind()
And i am trying to get values (value member) of checked checkboxes
I am trying in folllowing way but each time it rerurns false on
li.Selected
For Each li As ListItem In chkchrges.Items
If (li.Selected) Then
Dim XX = li.Value
'' Do something with Value
End If
Next
can I retrieve the name that caused a postback? (VB.NET)
View 5 RepliesIn Page_Load, Request["__EVENTTARGET"] is an empty string.IS there some way I can find out which button triggered the postback before hitting the buttons event handler
View 2 RepliesI have a treeview in my .aspx: <asp:TreeView ID="tvDocCatAndType" runat="server" /> Not much else going on in the page -- two <asp:LinkButtons> and one <asp:Label>; the page is a child of a master page, so these controls are within a <asp:Content> control. I populate the treeview in code -- just 3 node levels, including the root node. All nodes have checkboxes, and I initialize all node.Checked to true. I have some Javascript to do the usual check/uncheck up and down the tree as parent and child node checkboxes are toggled.
No matter how many checkboxes I clear in the UI, on postback every single node has node.Checked = true regardless of the state of the checkbox in the UI. This is not the first time I've used a treeview, but I've never had this problem before. I created this page by light adaptation of an earlier project that works fine.
I have some code here in view-page

View 1 RepliesI generate my check boxes dynamically:
for (int i = 0; i < dtCommon.Count; i++)
{
CheckBox newBox = new CheckBox();
newBox.Text = dtCommon[i].userName; [code]...
And when the save button is pressed I call this function:
protected void SaveUsers(object sender, EventArgs e)
{
}
How do I know which check boxes the user has checked?!
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
