Nested GridView, DataItem Returns Null In Child GridView's RowDataBound Event?
Jan 8, 2011
In a nested GridView (GridView inside a template column of parent GridView). I am binding child GridView to a DataTable in parent GridView's RowDataBound event. this works as it should. But the problem i am facing is in Child GridView's RowDataBound Event, when i try to access e.Row.DataItem property it returns null. I am expecting it to return DataRowView Type. which i will then use to set values of TextBox's.
[code]....

I have a Master/Slave GrisViews or some say Parent/Child GridViews.
i want to set my button visible=false in the child gridview if data is not exist.
i try this:
Protected Sub gv_child_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs)
If e.Row.RowType = DataControlRowType.DataRow Then
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)
Dim lblphoto As Label = CType(e.Row.Cells(11).Controls(1), Label)
[Code]......
but it does not working. the button is still there.

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.

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 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?

why the gridview RowDataBound event fires during a select command. I only expect it to run when the gridview is being populated with data. Is there some way to stop it from running when the select command is triggered?

I have created a gridview in code behind (as in its not physically present on the page). I want to know how to call it's rowdatabound event - as data is being bound to it. There happens to be a Gv.RowDataBound function, but how do I use it? (I want the same functionality as what the asp:gridview control has for its onrowdatabind attribute...)
GridView Gv = new GridView();
Gv.AutoGenerateColumns = false;
BoundField one = new BoundField();
one.DataField = "one";

in asp.net we can handle the RowDataBound event of the GridView control. this event fires when every row is added to the gridview.
i want to be able to handle this event in the gridview in a winforms application but i cannot find a similar event. my question is what is the event name that allows me to do the same as RowDataBound in asp.net?

When u have a gridview(lets say gridview1) and u associate an event
OnRowDataBound = "gridView1_RowDatabound"
and u usually start the event method as follows
protected void gridView1_RowDatabound(object sender, GridViewRowEventArgs e){
if (e.Row.RowType == DataControlRowType.DataRow){
do something..
}
}
Why do u have to check again if the row is data row, as i understand it gridview1_rowdatabound event occurs only when the rows are getting bound by the datasource u supplied. Why do u perform again this additional checking ?

Is it possible to retrieve the DataRowIndex of the binding datarow from its parent DataTable. I would use it to point again back to the datatable when i perform a delete operation. I can't use the DataItemIndex of GridView since the rows with RowState=Deleted still exists., so it won't point to the correct row of datatable.
