Forms Data Controls :: DatagridView Postback / Cannot Make The Datagridview's Buttonfield Respond?
Feb 17, 2011I am new to asp.net and was trying to use datagridview in my webform. I was able to bind it to my database but I cannot make the datagridview's buttonfield respond. It seems the grid's SelectedIndexChanged event is not being fired or has issues with postback. Even a very simple statement is not being executed by the program e.g.
protected void grid_SelectedIndexChanged(object sender, EventArgs e)
{
detailsLabel.Text = "asdfasdfsafasddf";
}
It seems the SelectedIndexChanged is not being fired. I have checked my IE and scripting is enabled.
I am using VS 2008 and IE7. Can anyone share a solution on how to solve this issue?

View 7 RepliesForms Data Controls :: Update 2.0 Formview Containing DataGridView
Feb 16, 2010Trying to update a .NET .20 datagridview in the following scenario. A page contains a formview. The formview contains a datagridview and some other fields not in the grid. The formview has its own ObjectDataSource and the datagridview has a separate ObjectDataSource. Each ObjectDataSource has an OnUpdating event. Clicking a Save button triggers the formview update event and the "non-grid" ObjectDataSource updates without a problem. In that same event, I also want to update the grid's ObjectDataSource. Because it's a grid, this OnUpdating event has to loop through each row, get the data for that row and set the UpdateParameter values. A foreach loop can get the values, but how do I trigger the update before looping to the next row?
Should I try calling a different kind of event for the DataGridView's ObjectDataSource? Or is there a way to get all the grid's new data at once as a dataset or datatable and do one bulk update? The datagridview does not have row-level edit/update buttons. It is meant to be an all-or-nothing kind of update.

Forms Data Controls :: DataGridView Equivalent Of GridView.Databind()?
Nov 12, 2010I have spent most of my time writing ASP.Net web pages, using VS 2005.

Forms Data Controls :: Separate DataSource For DropDownList In DataGridView?
Sep 8, 2010I am using a DataGridView and have a master table which contains values which different tables related to the master data, i.e. StatusID =1 in master table = TrailerStatus (1, 2, 3, 4 and their descriptions) are in a related table. I am able to retrieve the values from Table B 1 = Empty, 2 = Rejected, 3 = Onsite, etc. However, I don't know how to relate the master table StatusID = 1 to default my dropdown list from the relational table 1, 2, 3, 4.
I have been fighting with this for quite some time and just have not found a solid example of how to do this. I actually have two dropdownlists which will need to be correctly wired in order for my application to work.
This will also be an editable dataGridView but I will tackle that challenge once I get this first hair plucked from my butt.
There is some code-behind which doesn't work at all pertaining to a ;; gvSCACDetail_RowDataBound ;;
but I dont' think I can even get the code to compoile when this is not commented out.
Here are some of the details:
<td style="width: 700px; height: 20px">
<asp:GridView ID="gvSCACDetail" runat="server" AutoGenerateColumns="False" AutoGenerateEditButton="True" DataKeyNames="trailerid,locationid,scacid,statusid,capacityid" AutoGenerateDeleteButton="True" DataSourceID="SCACDetailView" Visible="False" Width="698px">
