Forms Data Controls :: Combining OnRowDataBound And OnRowCommand Events Causes OnRowCommand Not To Fire For GridView?

Jul 1, 2010

I'm using a standard GridView control inside of a web form. The web form uses a master page. The application is running within sharepoint (wss 3.0) environment. When i attach both the OnRowCommand and OnRowDatabound events to the gridview as shown in the markup below, only the OnRowDataBound event fires. The OnRowCommand never gets hit. When i press a button on a row, it posts back but never hits the onRowCommand event and simply falls through and repaints the page . However if i remove the OnRowDataBound event, the OnRowCommand event starts to fires correctly. I've tried a number of things...1. Hooking up the events in code instead of markup. (inside of PageLoad or PageInit)2. Changing the order in which the events are attached.

Forms Data Controls :: OnRowCommand Not Firing If Gridview Not Bound On Postback?

Jun 22, 2010

I have a webpage with many updatepanels. Each panel contains databound controls including gridviews (GV). They are bound at runtime so the number of gridview columns varies with each bind. the controls are bound only once in Page_Load event ( within if (!Page.IsPostBack) )I added a linkbutton to each header in the GV in the RowDataBound event. Once the header is clicked, the event is handled in the OnRowCommand and it calls a method to bind the controls with new data.Things work fine if the GV is bound with every postback (no if (!Page.IsPostBack) condition) but I don't want to bind all the controls with every postbackMy problem is that the OnRowCommand is not fired if the GV is not bound on the postbackI even tried to add click handler for the linkbutton but that didn't work either.

How To Bind The Data Inside This Table To A GridView And DataList

Mar 17, 2010

I am using an MS SQL Database with a table that has a DateTime column stored in it.

When I try to bind the data inside this table to a GridView and/or DataList the date shows up as (for example) '2010-03-03T00:00:00+01:00'.

In my GridView I tried to format that datetime by using the following 'BoundField' tag;

<asp:BoundField DataField="NewsDateEntered" HeaderText="Date Entered" DataFormatString = "{0:dd/MM/yyyy}" HtmlEncode="False" />

This is still wielding no results and I have tried to recreate the table and so on.

Web Forms :: Gridview OnRowCommand And PageIndexPaging Not Changing Event

Feb 15, 2010

I have a gridview that I am using to host some data. Each row in the gridview links to a blob and I am using the SOnRowCommand event to click on the row and to stream the blob(which is an image) out as a file. This works fine. However when i implement paging on the gridview with the paging event the handler think it is an OnRowCommand event and executes the code behing the OnRowCommand handler and not the pageindex change event.

[Code]....

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
DataTable dt = new DataTable();
dt = (DataTable)Session["data"];
GridView1.PageIndex = e.NewPageIndex;
GridView1.DataSource = dt;
GridView1.DataBind();
}
