Nested Gridview Edit Event

Posted By:      Posted Date: October 04, 2010    Points: 0   Category :ASP.Net

I have a Parent gridview with a nested gridview. Edit on the parent works fine. On the nested child gridview, when I click the edit button, the line goes into edit mode, but the parent row collapses.  To correct I added javascript to call the javascript function that is used to expand and collapse the rows.  It is located in the RowDataBound event of the parent gridview.  Based on the code samples I have, the way the process should work when the edit button is clicked is the RowCommand and then the RowEditing events for the child gridview are supposed to fire, followed by the RowDataBound for the parent.  The child events are firing after the parent though.  This wouldn't be a problem except that I am retrieving the parent line that holds the child record being edited so that value can be fed to the javascript function to expand the row. How can I fix this or work around it?

how to use nested gridview's rowupdating event

Hi all,            I have a GridView within a GridView. I want o access child gridview's rowupdating event. i want to update row.            this is my GridView's code as follows<asp:GridView ID="grdv1" runat="server" AutoGenerateColumns="false" EmptyDataText="No records found" OnRowDataBound="grdv1_RowDataBound" CellPadding="0" Width="500px" CellSpacing="0" BorderWidth="0"> <Columns> <asp:TemplateField> <ItemTemplate> <table width="100%"> <tr> <td align="center"> <asp:Label ID="lblName" runat="server" Text='<%# Eval("Name") %>' CssClass="nbdcontent"></asp:Label> </td> </tr> <tr> <td style="height: 150px"> <asp:GridView ID="grdv2" runat="server" AutoGenerateColumns="False&

Gridview edit mode - What event does enter key call?

I have sort of a very specific problem.  I have a gridview with a few different template columns and a commandfield with the standard "edit" link.  There is no sqldatasource associated with it at all.  In the code, I pull some data from an sql database into a datatable and set the gridview's datasource to be the datatable.This all works fine.  When I hit the "edit" button, the standard textbox shows up where it needs to so that I can edit the data.  The problem is the updating portion.  I have programatically removed the "update" button and left the "cancel" button for design reasons. I want the user to be able to hit "enter" in order to update the data in the data table.  Then, when they're ready, they can click a submit button which will extract the data from the datatable and update the database.I'm having trouble with this 'enter key' business.  When you edit the data and hit "enter" while in edit mode, the page posts back, and the previous values are placed in the gridview.  What event was just  called?  I need a way to take what the user put in and place it in my datatable.  What are my options?Thank you. 

Inplace Edit in GridView

In this article I am presenting a different way to look at EditItemTemplate, using which user navigation for editing is reduced and . it looks very different (see screeen shots) then regular implementation of GridView.

Edit GridView Individual Cells in ASP.NET

The ASP.NET GridView allows for a row of data to be edited by setting the EditIndex property of the GridView, placing the entire row in edit mode.

You may not want the entire row in edit mode if you are using DropDownList controls for several columns in the EditItemTemplate. If each DropDownList has many options then loading them all at once may result in a sluggish page. Also, if your data structure is more like a 2 dimensional array rather than a set of rows, you may want to edit each cell individually.

Here I will demonstrate how to achieve this and also how to deal with event validation without disabling it.

ASP.Net Gridview Edit Update Cancel Commands

In ASP.Net 2.0, GridView Control also provides the functionality to edit and update the data retrieved from the database using CommandField template. You can cancel the action using Cancel Command of the CommandField. GridView consists of events that can be used to perform the actions like edit, update and cancel upon the Data items displayed in the ASP.Net GridView Data Control.

ASP.NET GridView - edit records using JQuery Dialog

There are many ways in which you could modify modular data in Grid View:

2. By using separate pages for Edit

How to let user edit selected gridview columns, not entire row



I've got a gridview I would like to let the user edit a couple of columns.  Seems like everything I'm coming across so far makes the entire row editable.  

Hopefully the solution isn't too complicated.  Can someone point me in the right direction?


LINQ with GridView and edit fields


My project includes a grid view which displays information of inventory items (Assets), data is quried from AssetTable. The GridView has a command field to allow editing, below is a description of the tables and how data is displayed


BuildingTable: (BuildingID, BuildingName)

AssetTable: (BuildingID,..,....,....)


ItemTemplate: Using a LINQ query I join the two table and displays in a label control a string which includes BuildingID and BuildingName (5 North Building)

 EditItemTemplate: Using a LINQ query I populate a DropDownList with strings of BuildingID and BuildingName same as above.
Here  issue which I need to resolve:
1.  ItemTemplate display the correct information (BuildingID BuildingName) but when I switch to EditItemTemplate the pair that is 
displayed is the first one on the list, how do I make is scroll to the item which was displayed in the label ?
<asp:CommandField ShowEditButton="True" >

Editable multiple nested gridview


Greetings everyone,

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: http://www.codeproject.com/KB/webforms/EditNestedGridView.aspx

And I understand how I can fix my issue on a 2 level nested gridview, by simply adding the C# code:

protected void GridView2_RowEditing(object sender, GridViewEditEventArgs e)
            GridView gvTemp = (GridView)sender;
            gvUniqueID = gvTemp.UniqueID;
            gvEditIndex = e.NewEditIndex;

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:

jquery datepicker not popping up in Gridview Edit Template textbox


I have a gridview that I can't for the life of me get the datepicker calender to pop up for.  I've been using the datepicker for months very successfully for a variety of textboxes on the page and inside of formviews but this is the first time I've tried using with gridview.  I didn't expect any issues however can't seem to find anything to work.  I have searched the forums for 2 days and attempted any suggestions found within the solutions to no avail.  I've tried using the CSS to link the datepicker but everything stopped working when I changed the code and my page which uses a css style already got all distorted looking.  Please help!

Here is my gridview (only included a part b/c it is large and am only having problem with the datepicker for the date completed text box)

<asp:GridView ID="GridViewCompleted" runat="server" AllowPaging="True" AllowSorting="True"
        AutoGenerateColumns="False" BackColor="#CCCCCC" BorderColor="#999999" BorderStyle="Solid"

gridview tablecell text emptystring in RowDataBound event when editing


HI and thanks in advance.  asp.net using vb, using a codebehind page.

I have a relatively simple gridview bound to an product table that displays great.  The problem comes when I choose to edit a row.  When I do so, the gridviews' RowDataBound event fires and the values of the text properties of the tablecells in the row evaluate to "" emptystring. 

I do notice that if I break within the GridView1_RowDataBound event during a refresh of the page, the values are there.  But again, when I hit the "Edit" button in the first column (the CommandField column) .  Text properties of the cells resolve to ""

 Here is the code for the event, followed by the gridview in the form (inside an updatepanel)

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
        If e.Row.RowType = DataControlRowType.DataRow Then  ' not a header, footer row.. etc.
            Dim cellProductNumber As TableCell = e.Row.Cells(3) ' ProductNumber column

'>>>>> after clicking "update", even though a value displays in the gridview,
