I have designed a collapsible nested gridview project using this article as a reference Collapsible Nested GridView with Paging using ASP.Net. I am trying to modify the code to collapse a gridview when another gridview is expanded so that only one nested gridview will be open at a time.

I have a GridView with an associated DataKey, which is the item ID. How do I retrieve that value inside the RowCommand event?
This seems to work, but I don't like the cast to LinkButton (what if some other command is firing the event?), and I'm not too confident about the NamingContainer bit.
LinkButton lb = (LinkButton)e.CommandSource;
GridViewRow gvr = (GridViewRow)lb.NamingContainer;
int id = (int)grid.DataKeys[gvr.RowIndex].Value;
I'm aware that I could instead pass that ID as the CommandArgument, but I chose to use DataKey to give me more flexibility.
I'm also aware that it's possible to use a hidden field for the ID, but I consider that a hack that I don't want to use.

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.

I have two listviews. What i want to do is that when the nested listview emptydatatemplate shows i want to put a hyperlink with a querystring in it, the id in the querystring should be the fk in the nested listview. Is it possible to bind the hyperlink with the id in codebehind? I use two object datasources. Does it matter where i put the nested listview now i have it in the parents itemtemplate. Also it seems to be a problem to set the datakeynames in the nested listview, what could be the reaso for that.

I have a nested gridview dynamically added. It seems I resolved all issues with the loading this control on a parent page along with other controls and I can trigger the edit of the first level - the master part of the gridview. However, I cannot trigger the edit on a child gridview.
OnRowEditing="grdChildGridEdit_RowEditing"
The master and the child gridviews have objectdatasources in a markup but I have to do the additional data binding after the loading the control on the parent page (see the code below). I'm doing that additional data binding only for the master gridview that is working fine and shows the data for the master and the child gridviews. When I click the Edit button on the master gridview it shows text boxes for the editing but when I click the Edit button on the child gridview it's doing nothing and moreover the editing mode for the master gridview is going back to the initial stage (labels).
I was trying to trigger it throughuse the registering the event:

I have a nested gridview containing gridviews: gvMaster(Parent) and gvAlternate(Child)
If I select a row in gvAlternate is there a way for me to find out what gvMaster row it is under? I want to highlight the selected gvAlternate row and the gvMaster row that it is under.
[code]....
I can get a certain set of rows of gvAlternate only by referencing which gvAlternate control set I want to access: this is based on the gvMaster.Rows and then using the FindControl and id name:
GridView
gv = (GridView)this.gvMaster.Rows[aRowNumber].FindControl("gvAlternate");
Therefore, it is true that a set of rows in a nested gridview is tied to a specific row in its master gridview, the question is does the child gridview know which set it's connected to or does it's master know if a childset has been selected?

I have been looking at the guide: [URL] ....
Is it possible to have an edit function, so you can edit the expanded records - fx if you want to add/correct information.
Adding a normal edit/delete button like on a normal gridview doesn't seem to work when it is nested.

e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#FFC080';")
e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='';")
Dim lblitemid As Label = CType(e.Row.Cells(1).Controls(1), Label)

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 am having my first go at a nested gridview within a gridview. I have successfully loaded the data and it displays fine. Within the child gridview I have two textboxes that the customer can change. I also have an Save button. When the customer selects the save button the RowCommand for the child grid executes as it should. However I am unable to figure out how to access the two textboxes.
In the past I have got the row index from e.CommandArgument, established the correct GridViewRow using the gridview ID and the row index, and then used findcontrol to get the textbox
int index =
Convert.ToInt32(e.CommandArgument);
GridViewRow row = gvGridView.Rows[index];
TextBox txtName = row.FindControl("txtName")
as TextBox;
But when working within the Child GridView RowCommand event I am unable to figure out how to gain access to the textbox. The child gridview is not recognized.
