How to delete row per row basis in grid view



I found this code and tried to implement it in my project. But before running, I got few question. What I want to do is able to delete 1 row each time I click on a button or link.

1. Where is the firing event comes from?

2. Do I need to add a button or link each row (another column)?

3. How does the following code works?

            int rowIndex = (int)gvDetail.DataKeys[e.RowIndex].Value;

        protected void gvDetail_RowCommand(object sender, GridViewCommandEventArgs e)
            if (e.CommandName == "Delete")


Thank You.

How to take value of bound field of grid in a variable or in a textbox.

ASP.NET Grid View Paging and GridDataRowBound Problem -



I have a problem displaying data in a Grid View control when I set a row to visible = false when a certain condition is true.

For example, if a DataRowData value has a condition set to true (custom in table) I set the visible property to false, so the data row will not be visible at run time.

The problem is that I'm using paging (10 rows per page) and if 8 of those rows fall into the true condition that won't show the row, that grid view page will only show two rows of data in page 1. The worst scenario is that if I go to page 2 of the grid view and all the rows (10) fall into the true condition, that grid view page will not show any data at all.

How can I show 10 rows of data at all times in a gridview? In other words, I would like to just show the visible rows at all times.

Any help will be greatly appreciated.


Change grid view from table to other HTML layout



You'll have to excuse my ignorance, I'm coming at this from a front-end perspective, and don't really know how to deal with data views in ASP.NET.

Basically, I'm trying to change the layout of some repeated data from a straight table, to something more design-heavy.  It's the same data, just re-organised slightly.  The current ASP.NET code looks like this:

                    <asp:GridView ID="GVMoments" runat="server" AllowPaging="True" AllowSorting="True"
                        AutoGenerateColumns="False" PageSize="20" RowHeaderColumn="FirstName"
                        SkinID="GroupSkin" DataKeyNames="moment_id" 
                        <PagerSettings Mode="NumericFirstLast" PageButtonCount="20" Position="TopAndBottom" />
                        <RowStyle />
                                <asp:BoundField DataField="moment_id" HeaderText="moment_id" ReadOnly="True" SortExpression="moment_id"
                                    Visible="False" In

Calculated date field displays differently in List View and Data View web parts

In SharePoint GUI I created a simple custom list with a calculated Date/Time field (Due).  The calculation is =[Created]+7.  I'm trying to display this data on a page using a DVWP.  But first, for testing purposes, I also created a second calculated Date/Time (TestCreate) field in my custom list that is simply =[Created]. In the List View from within SharePoint, the dates show as expected (for example): Created = 8/12/2010 3:45 PM Due = 8/19/2010 3:45 PM TestCreate = 8/12/2010 3:45 PM In SharePoint Designer, I added a Data View web part and the above three data elements (each configured to display mm/dd/yyyy hh:mm:ss tt).  I see the time displayed for the example list item as: Created = 8/12/2010 3:45:30 PM Due = 8/19/2010 10:45:00 AM TestCreate = 8/12/2010 10:45:00 AM I've tested a couple scenarios and the calculated fields always display five hours in the past (along with dropping the seconds).  It seems like the DVWP is returning the date in a different time zone (with no seconds).  The lcid is set right (1033).  I didn't see any time zone settings for the DVWP specifically.  I'm basically stuck.  Could someone help me figure this one out. Thanks.
