I have a gridview with a nested placeholder in each rows. I nested some checkboxes in each placeholders in each rows dynamically, so their ServerIDs are not the same (I dont want to use nested gridview). at the end in a button event I want to count checked checkboxes in gridview while I can not use findcontrol() method in each rows to find checkboxes due to their different ServerIDs.

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 have two datalists. Data list 1 shows regions; data list 2 is nested in datalist 1 and shows the cities in those regions. The two datalists bind ok.
However, I'm trying to call a click event from the nested data list (2) so that when clicked, the cityID nested in datalist 2 will appear in a label.
Here is a simplified version of the code.
[Code]....
Is 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.
I am trying to find the text property of a label that is nested within a DataList within a FormView. The FormView and the DataList have different datasources.
What I actuallt need to do specifially is assign the number of rows in the DataList to the Label in the DataList. I used the code below to find it but it keeps giving me an error about not finding the object;

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.

View 1 RepliesI 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.
View 1 Replies i have the following nested gridview
i could get the inner gridview onRowDataBound working by setting that directly in the gridview

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:
[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 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 (gridview within gridview) that I need to render beneath the outer gridview.
I keep finding examples online of showing a nested gridview in the last column of the outer gridview but I need to show my nested gridview instead under the outer gridview.
I was certain that I had done this before by putting a row (<TR>) inside the TemplateField so that the nested gridview would display under the outer gridview. I am getting the data ok for the nested gridview, that is not a problem. The only issue I am having is making the inner gridview display under the outer gridview.
btw, the error is below:
<ERROR>
Type 'System.Web.UI.WebControls.TemplateField' does not have a public property named 'tr'.
</ERROR>
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 a parent gridview5 with child gridview 6, today i deployed it to our dev server and on that server we have alot more records, so for the nested gridviews i need to enable paging on the parent gridview5. Doing so works fine, until i make a selection within the child gridview6, once any selection is made, and i try to page the page throws an error, i have the following bound to the parent gridview5.

I have a gridview (gvNested) nested inside another gridview (gvParent). I want to get the selected value of the nested gridview, but keep getting the classic 'object reference not set to an instance' error. I thought that this would work

I've got this page where I display a 3 level nested gridview. First gridview displays data, 2nd one displays data based on the 1st one's row and 3rd one displays data based on the 2nd gridview. All of this works perfectly, including the edit mode for the 3rd gridview.
The issue comes when I make each gridview collapsible, again, it works fine but when I click on "Edit" on the 3rd gridview all the grids collapse, I can then re-open them and the "edit mode" is still present and I can still save my updated data. But that collapsing thing is quite annoying. I based a lot of my code from this page: [URL] And I understand how I can fix my issue on a 2 level nested gridview, by simply adding the C# code:

This makes allows me to save the index and prevent it from collapsing when I'm editing. Unfortunately, because I'm actually editing the 3rd gridview, if I code:

That simply doesn't work because I get the error "GridView2 does not exist in the current context". I also tried adding it to the .designer.cs page, but that doesn't change anything and still doesn't work. I'm not at work atm, and hence cannot paste the entire code, however, would anyone still have any idea as to how I can fix that issue?

I have an image button on my gridview in one column, and in the next column, I have a nested gridview. What I am looking to do, is to use my image button as a way to show and hide my nested gridview. I do not want to use JavaScript, because my page already uses a great deal of JavaScript. Therefore, I want to use code behind on the button, this is what I have done so far:
ImageButton b = (Button)sender;
GridViewRow row = (GridViewRow)b.NamingContainer;
if (row != null) {
int rowIndex = row.RowIndex;
How do I use my selected row index to call the nested gridview to be visible and not visible?
