Using a GridView in asp.net but am using a submit button outside the GridView

I am using a GridView to display error information to be verified by the user. Then the user is given fillable fields (datepicker, dropdownlist, textbox) to fix the errors. These are outside of the GridView.
After, they have a submit button to save the changes to a sql log. The problem I am having is that because I'm passing in object sender, GridViewRowEventsArg e, the button doesn't recognize the GridView and I get an error:
No overload for 'btnSaveMemberErrorEdit_ButtonClicked' matches delegate 'System.EventHandler'
I am using asp.net with c# code behind. Sample code is:
ASP:
<div id="actionItemAccordion">
<h3>Action Items</h3>
<asp:Panel runat="server">
<asp:GridView runat="server" ID="gridActionItems" DataKeyNames="ErrorKey"
AutoGenerateColumns="false" EmptyDataText="No Action Items Were Found." ShowHeader="true"

Code Behind:
protected void btnSaveErrorEdit_ButtonClicked(object sender, GridViewRowEventArgs e)
{
int hiddenErrorKey = Convert.ToInt32(e.Row.Cells[5].Text);
this.assignCorrect = e.Row.Cells[4].Text;
SqlCommand command = new SqlCommand("some_storedProc");
command.CommandType = CommandType.StoredProcedure;
command.Parameters.Add("#ErrorKey", SqlDbType.Int).Value = hiddenErrorKey;
command.Parameters.Add("#EffectiveDate", SqlDbType.DateTime).Value = this.txtEffectiveDate;
command.Parameters.Add("#TerminationDate", SqlDbType.DateTime).Value = this.txtTerminationDate;
command.Parameters.Add("#Notes", SqlDbType.VarChar, -1).Value = this.txtNotes;
command.Parameters.Add("#NameOfInputUser", SqlDbType.VarChar, 50).Value = this.lblInputUserName;
command.Parameters.Add("#Code", SqlDbType.VarChar, 1).Value = this.assignWinner;
Utilities.Exec_Qry(this.Application["some_connection"].ToString(), command);
}

You need to change the function to take arguments for the asp:button
(object sender, EventArgs e)
Then you can grab the GridView in the behind code using
var button = sender as Button;
var view = button.FindControl("gridActionItems") as GridView;
Then you can access the elements as needed.

Trying to Change the color of the background label in ListView

I am trying to change the color of the background when twa is at different values but it with my current code, the data is not firing, but when I remove the
<asp: Label id="TWAlabel" OnDataBinding="ListView2_OnDataBinding">
But when I remove OnDataBinding the data fires, so I have no idea what is wrong. I am doing this in Asp.net(C#), JavaScript, and the data is sourced from an Access database. Here is my code:
<style>
.YellowThis
{
background-color:yellow;
}
.RedThis
{
background-color:red;
}
.GreenThis
{
background-color:green;

You could do it in your code behind. Iterate through your list items.
protected void add_color()
{
foreach(ListItem li in ListView2.Items)
{
Label your_label = (Label)li.FindControl" your_label_name";
int TWA = Convert.ToInt32(your_label);
if (TWA > 90)
{
your_label.BackColor = System.Drawing.Color.Yellow
}
}
}

This questions is more than 1 year old and I'm not sure if it'll help anyone here.
I think what went wrong in your code is because your listview databinding event was created in Label instead of creating it in the Listview.
What you can do is create a databinding event in ListView control and read the value of the TWA label and then set your ListView control background color.

RadListView automatically sorting on ID column

I am using the Telerik radlistview o display some results, i perform some grouping in my query and return a sorted and ordered resultset and set it to the datasource. For some reason (which i have been battling with all morning) the ListView re-orders the results by the ID column.
<telerik:RadListView runat="server" ID="rlThumbnailView" OnNeedDataSource="rlThumbnailView_NeedDataSource"
AllowPaging="true" PageSize="8" OnDataBound="rlThumbnailView_DataBound" OnItemDataBound="rlThumbnailView_ItemDataBound">
<LayoutTemplate>
<span style="vertical-align: top; position: relative; top: 4px">Displaying page
<%#Container.CurrentPageIndex + 1 %>

<%#Container.PageCount %></span> </span>
<br />
<div id="list">
<asp:Panel runat="server" ID="Panel1" Style="float: left; margin-left: 160px" Visible="<%#Container.PageCount > 1 %>">
<asp:Button runat="server" ID="PrevButton" CommandName="Page" CommandArgument="Prev"
Text="Prev Page" Enabled="<%#Container.CurrentPageIndex > 0 %>" />
<asp:Button runat="server" ID="NextButton" CommandName="Page" CommandArgument="Next"
Text="Next Page" Enabled="<%#Container.CurrentPageIndex < Container.PageCount - 1 %>" />
</asp:Panel>
<div>

Width="150px" CausesValidation="false" />
</div>
<div style="clear: both;">
</div>
<asp:Panel ID="itemPlaceholder" runat="server">
</asp:Panel>
<div style="clear: both;">
</div>
</div>
</LayoutTemplate>
<ItemTemplate>
<div id="wrapper" runat="server" style="float: left; margin-top: 2px; margin-bottom: 2px;">
<telerik:RadBinaryImage ID="ThumnailImage1" runat="server" />
UPC:
<asp:Label ID="lblUPC" runat="server"></asp:Label><br />

I beleive this is based on the standard microsoft listview,

For anybody who faces the same issue, the answer appears here:

seems to be a bug with Telerik

Panel visibilty on/off toggle effect not working

I've a got ListBox called lbxUpcommingEvents. When the index is changed the event handler is fired to check for duplicate records. If duplicates are not found, a panel called pnlAction inside a formview is turned on by the way of display style. If dups are found another panel pnlActionCancel is turned on and the oter is tuned off. Basically a toogle effect.
I've tried the visible property, viewstate property, but it does not work and I can't figure it out so once again, I seek wizdom from the collective. Here is my code.
protected void lbxUpcommingEvents_OnSelectedIndexChanged(object sender, EventArgs e)
{
pnlEventsSignUp.Visible = true;
string _selectedItemValue = lbxUpcommingEvents.SelectedValue.ToString();
int _eventid = Convert.ToInt32(_selectedItemValue);
Guid _memberId = Guid.Empty;
_memberId = new Guid(Session["myId"].ToString());
// Check for existing signup
EventsMemberSignup _createSingup = new EventsMemberSignup();
dsEventsSingupTableAdapters.MemberEventsTableAdapter da = new dsEventsSingupTableAdapters.MemberEventsTableAdapter();
dsEventsSingup.MemberEventsDataTable dt = da.GetDataForDupCheck(_memberId, _eventid);
if (dt.Rows.Count == 1)
{
Panel pnlAction = (Panel)(fvEventSignUp.FindControl("pnlAction"));
//pnlAction.Visible = false;
pnlAction.Style.Add("display","none");
Panel pnlActionCancel = (Panel)(fvEventSignUp.FindControl("pnlActionCancel"));
//pnlActionCancel.Visible = true;
pnlActionCancel.Style.Remove("display");
}
else
{
Panel pnlActionCancel = (Panel)(fvEventSignUp.FindControl("pnlActionCancel"));
//pnlActionCancel.Visible = false;
pnlActionCancel.Style.Add("display", "none");
Panel pnlAction = (Panel)(fvEventSignUp.FindControl("pnlAction"));
//pnlAction.Visible = true;
pnlAction.Style.Remove("display");
}

I've set the ViewStateMode to "Disabled". I'm just hoping it won't back fire somewhere else.

Your existing code might work if you drop an update panel and place your controls inside it.
Alternatively you can create a property in your page like
private bool myRowCount;
protected bool HasRowsMyData
{
get { return myRowCount; }
set { myRowCount=value; }
}
Then inside your selectedIndex change event
if (dt.Rows.Count == 1)
{
HasRowsMyData=true;
//DataBind your controls here
YourUpdatePanel.Update();
}
Inside your aspx on panels you can set each panel's visible property like this so whenever page is updated they will turn on/off depeding upon the result
Visible='<%#HasRowsMyData%>'
Visible='<%#!HasRowsMyData%>'
If you like to do it client side I advise jQuery's toggle function
jQuey:toggle()

how do i reference a listview control that is nested in the itemtemplate of another listview control?

I have a listview control that is nested in the item template of another listview control that i'm trying to reference in codebehind using the .FindControl() method, but it keeps returning null. After get this to work, I'll need to reference a ComboBox inside of the inner listview. Here is where I am so far:
ListView lsvTickets
ItemTemplate
Listview lsvActions
ItemTemplate
ComboBox cboAssignees
I'm using the following code to attempt the reference in code behind:
var actions = (RadListView)lsvTickets.FindControl("lsvActions");
But this is returning null. I thought I would only have to do something like this to achieve the final desired result:
var assignees = (RadComboBox)lsvTickets.FindControl("lsvActions").FindControl("cboAssignees")
Can anyone help? What am I doing wrong here? Here's the full layout for those of you it would help:

You're looking for a combobox in a control that potentially has many lines (thus rows of combobox instances ) - it doesn’t know which one you’re looking for.
Obviously I don’t know what you need to do to the combobox but you should look at
alternate approaches.
Take a look at using the OnItemDataBound event of lsvActions
Then add code such as …
protected void lsvActions_ItemDataBound(object sender, GridItemEventArgs e)
{
if (e.Item is GridDataItem)
{
GridDataItem item = (GridDataItem)e.Item;
RadComboBox myCBO = (RadComboBox)item.FindControl("cboStatus")
myCBO.Visible = false;
}
}
...also, just a general tip, I usually find using OnNeedDataSource to load RadGrids and ListViews saves a lot of headaches.
Hope that helps.
