I have a nested gridview which has been working fine. Now I need to turn the inner gridview off based on some condition: a IF block is added to the existing RowDataBound event of the outer gridview. Now I'm getting "the Object reference not set to an instance of an object" error. What should be the proper way to go about this? The code:

In addition, is there a way to "switch" columns of the inner gridview? For example, column 1 is "City", column 2 is "Price". If user selects to sort by "Price", I woud like column 1 be "Price" and column 2 be "City". Is this has to be done programmatically or if there's other way?
I followed your topic to select all rows with checkbox in gridview header and it is verygoodThis is code :
<script type="text/javascript"> function CheckAll(objRef) {
var grid = document.getElementById("<%=Grd_Data.ClientID%>");
var headerCheckBox = document.getElementById("ChkAll");
var inputs = grid.getElementsByTagName("input"); for (var i = 0; i < inputs.length; i++) {
if (inputs[i].type == "checkbox") { if (objRef.checked) { inputs[i].checked = true;
} else { inputs[i].checked = false; } } } }</script>
But i noticed that when i deselect a row in gridview the checkbox in header is still checked.How can i fix this problem that when i deselect one row from gridview the checkbox in grid header change to be unchecked ?
How can i add Paging for a nested Gridview..
View 1 RepliesI have parent gridview5 and nested child gridview6 within it. The page is working as expected and formatted as i need it now.. I added a select button to the child gridview6 and when i click on it i get an error: {"Object reference not set to an instance of an object."}
I found examples of using the find control, but within the parent gridview.. and i use that fine with other controls.. but cant figure out the right combination of finding the selected row for the nested gridview so that i can display a modalpopup.

why file upload returns null in inner gridview..same code working properly for outer gridview
I am requested by my manager to develop a web page called staff deployment plan that will involve two GridViews, that is the Parent GridView and Child GridView. The Parent GridView will display two columns which are EmployeeNames and WorkingDays - the working days column is a heading of Child GridView and the child gridview displays columns as current working days for example: the month of November 2014 has 20 working days excluding weekends and public holidays in South Africa, so the columns for child gridview are like this:
3 Nov, 4 Nov, 6 Nov...etc
The problem that am experiencing now:
Is to add LinkButton for each column on the Child GridView and to create command event for each linkbutton inside a child gridview (remember this child gridview is inside a parent gridview) and the link button when is click it should display a popup window.

I'm trying to create a nested gridview, but I'm stuck at the editing/deleting part of the nested gridview. (Below is my code).The nested gridviews are filling out nice, I've set the DeleteParameter in the SQLDataSource, but I'm still getting this error when trying to delete a criteria: 'The Gridview 'gvCriteria' fired event RowDeleting which wasn't handled.'I've tried to create a method 'gvCriteria_RowDeleting', but that didn't seem to work out.Someone who can give me a piece of advice? Would it be possible to fill the gridview without using gvDomain_rowDataBound? Dries

I tryed to put a nested Gridviews (parent-child) in an UpdatePanel, but it didn 't work as I want. Firstly the code of the Gridview (its from the example reffering to this [URL] .....)
<form id="form1" runat="server">
<asp:ScriptManager ID="scriptMgr" runat="server" EnablePartialRendering="true" />
<asp:UpdatePanel ID="updatePnl" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:GridView ID="gvCustomers" runat="server" AutoGenerateColumns="False" CssClass="Grid"
DataKeyNames="CustomerID" onrowcommand="RowCommand1">
[CODE]...
in the scriptManager, no exception will be shown, but on RowCommand a complete Postback is done.

View 2 RepliesIs there a better, cleaner way to do this in ASP.NET 2.0?
An ASP.NET 2.0 page displays a datalist of records. Each record can have many dates, so the dates are in a nested gridview (I chose a gridview over a datalist here because we want to be able to delete a date and this is easier done in a gridview). The parent record can never be deleted.
The display works fine: the nested gridview gets its datasource during the parent datalist's OnItemDataBound event.
The problem: the nested gridview's delete function. The date gets deleted without a problem (handled in the OnRowDeleting event), but somehow the redisplay is untying all the other nested gridviews from their datasources. The delete does not appear to cause a page postback, so I don't know how the other nested gridviews are losing their datasources.

Basically as the title of this thread states, I have a FormView that has a GridView inside it and my ObjectDataSource that populates this grid cannot access the Grid.
The Control Id needs to be the name of the Grid I want to access, however through the 'wizard' the Control parameter drop down cannot 'see' the grid I need, only the FormView that is in.
I have tried numerous ways to get round this and am struggling now..
I've tried the following...
ControlID="FormView.GridView1"
ControlID="FormView.FindControl("GridView1")
ControlID="<%= GetNameOfGrid %>"
and numerous other attempts that also failed that I now cant remember...
I'm trying to check dynamically generated "checkbox" value inside Listview.

In Nested Grid, we get a '+' sign. The problem is that '+' sign appears all times, even if there are no child records for that row. 1. Can we enable/disable OR Hide/Unhide '+' sign. depending on if child rows exits.2. OR alteast we can put some bgcolor indicating to user that this record do have child rows. Without any indicator user may feel quite annoying to click on '+' sign and nothing happens.
