Here's the image
I set the DataKeyName of the Parent gridview to EmpNo and LeaveTraId, I wanted to pull those datakeys up to include in my query getting the value Remarks field from database.
I used OnRowDataBound event of parent grid to populate the second grid.
I did the necessary steps, show a footer, put in a button and text box, set their id's up.
Here is my code behind (VB). It's saying that Event 'Inserting' cannot be found. I'm stumped. (The gridview is set up to insert/delete/edit)

View 4 RepliesHow to add checked records in nested gridview to database in ASP.Net?
View 1 RepliesIn 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'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

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.
iam trying to insert new record through gridveiw footer template field and its should added in sql database
i don't want to use sqldatasource, i wants to do through code.
Scenario : I have two database tables with one to many relationship. eg:- City and Related news. So I have a gridview(Gridview1) which lists out all the cities and allows edit, delete of the gridview rows. Now since i wanted to display all news for the city, i have a nested gridview as a column in this Gridview1. This nested gridview displays all the news for the cities. And I have edit, delete buttons for this gridview too - So far, good - works fine.
Now what I would like to do is - To insert a new news item for a city. For this, I attached a detailsview to my nested grid(gridview2), and tried to insert. I need the primary key id of city table from the first grid (gridview1) to insert the news into the second database table and I could not access this value from the parent gridview. My gridview1 does not have datakeyname, it is programatically bound.
Also, When the gridview/detailsview is nested, it does not get listed in the event-handler list. So I cannot use say, detailsview1_iteminserting. I do not how to add this event handler
Has anybody done anything similar? When I started, it looked like a pretty straightforward thing - There must be some way to do this. But I just can't get it to work. How do you usually insert into the child table in a one-to-many relationship? Should i just be using two separate gridviews?
I have a customized gridvew i.e. grvResult. There is a textbox and a InsertButton in the footer.
If there is a data populated into gridview it is showing GridView footer and inserting data but if there is no data in gridview then its footer also not visible.
I have tried in two ways to make footer visible but it is showing following error:
Object reference not set to an instance of an object.

Here is my code in front and behind:

I have a GridView, with a DropDownList as one of the Columns. I can get the SelectedIndexChanged method to trigger - but I cannot figure out how to get other Data regarding which row this triggered on i.e. if I could get the value in the ID column (DocID below), that would be great. My code is a bit too long, so I am just posting snippets. In the *.aspx file I have:
[Code]....
In the *.aspx.cs File:
[Code]....
I am wondering if I can get the DocID from within StatusDropDownList_SelectedIndexChanged - so that I can make appropriate changes to the Database. For e.g. in the RowDataBound event, which I had a GridViewRowEventArgs e, I could easily do e.Row.DataItem - to get the DataItem, I am wondering if I get/do something similar in the SelectedIndexChanged method. (I would prefer this be not the GridView Row Index i.e. I would prefer the DataItem if possible.)
I ran into this kind of situation many times without a nice solution. Binding a data source to a gridview and one of the column require nested query. Is it possible to have a callback function other than Eval()?
something like CallbackFunc(Eval("SomeField"));
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.
I have a page where there are two nested gridview, I have a column in the child gridview that uses a function to display the data.This function uses the id of the id of the father and son as parameters. I tried the code below, but does not work ...
