AJAX :: ModalPopupExtender And UpdatePanels - Find The Rows In The Datagrid That Have Been Checked With The Checkboxes?
Jun 22, 2010
I have created a popup window with the modalpopupextender. Inside the popup window is an Updatepanel that contains an OK button, a Search Button, a databound Datagrid and some checkboxes.
The problem is that when i press the OK button, i want to find the rows in the datagrid that have been checked with the checkboxes.... but i can't find the datagrid on the page! Any suggestions to how i can find the datagrid in the updatepanel?

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.

I am at a stand still here. I have a GridView in which I'm moving the DetailsView (bound to a sqldatasource) to the ModalPopupExtender for Updating. DetailsView for the selected row is contained in an updatepanel with the UpdateMode set to Conditional. My Select function works properly, filling in the fields of DetailsView, but I cannot figure out how to get the Update function to work properly. I think what I am missing is a method to get the the key values and control values into the SqlDataSource UpdateParameters.

I need to select my field data using a 3 step drownlist process (shown in the following screenshot):
But I can't find a way to get the Model SelectedValue and SelectedItem when Select is clicked. After it's selected it has to be filled in the Autofield on the background, and when close is pressed the original value has to be reloaded.
This is my ASP Code:

I 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 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 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

note that the scenario is ASP.NET Webforms + Master - Content page which mess up the ids.
I have, say, three checkboxes
<asp:CheckBox ID="chkConsultantQuality" runat="server"
CssClass="company"/>
<asp:CheckBox ID="chkConsultantEnvironment" runat="server"
CssClass="company"/>
<asp:CheckBox ID="chkConsultantSafety" runat="server"
CssClass="company"/>
I would like to make a div id="CompanyPanel" on click event of each checkbox according to the following condition
visible if any of the checkboxes are checked.
hidden if all of the checkboxes are unchecked.
I am planning to use jQuery since I am selecting by class name. I could do it with jQuery.each on the class='company' by checking each for a checked flag.

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.

in my procedure in code-behind I am trying to create a DataGrid with autoGenerateColumns = true :
DataGrid NewDg = new DataGrid();
NewDg.AutoGenerateColumns = true;
NewDg.Width = Unit.Percentage(100.00);
NewDg.DataSource = ds;
NewDg.DataBind();
I need to also add another column (TemplateColumn maybe) of CheckBoxes to this Grid.Do you know how to do that??
I have tried that:
TemplateColumn t = new TemplateColumn();
CheckBox c = new CheckBox();
t.ItemTemplate = (ITemplate)c;
NewDg.Columns.Add(t);
I get the following exception trace:
System.InvalidCastException: Unable to cast object of type 'System.Web.UI.WebControls.CheckBox' to type 'System.Web.UI.ITemplate'. at Default2.DataGrid1_ItemDataBound(Object sender, DataGridItemEventArgs e) in c:UserssaherDocumentsTreeTestTreeDemoDefault2.aspx.cs:line 116 at System.Web.UI.WebControls.DataGrid.OnItemDataBound(DataGridItemEventArgs e) at System.Web.UI.WebControls.DataGrid.CreateItem(Int32 itemIndex, Int32 dataSourceIndex, ListItemType itemType, Boolean dataBind, Object dataItem, DataGridColumn[] columns, TableRowCollection rows, PagedDataSource pagedDataSource) at System.Web.UI.WebControls.DataGrid.CreateControlHierarchy(Boolean useDataSource) at System.Web.UI.WebControls.BaseDataList.OnDataBinding(EventArgs e) at System.Web.UI.WebControls.BaseDataList.DataBind() at Default2.BindData() in c:UserssaherDocumentsTreeTestTreeDemoDefault2.aspx.cs:line 44
