Forms Data Controls :: Gridview RowCommand Event Returning Null Values?

Sep 2, 2010

I'm trying to retreive values entered by users in the textboxes in the footer of the gridview and insert these values into another sql table.My code is as follows :-

protected void GridView2_RowCommand(object sender, GridViewCommandEventArgs e)
{
if(e.CommandName.Equals("addnew"))
{
TextBox t1 = (TextBox)GridView2.FooterRow.FindControl("tfrm");
string frm = t1.Text;
TextBox t2 = (TextBox)GridView2.FooterRow.FindControl("tsub");
string sub = t2.Text;
string cmd = "insert into suggestions values('" + frm + "','" + sub + "','c','c')";
con.Open();
SqlCommand com = new SqlCommand(cmd,con);
int a = com.ExecuteNonQuery();
GridView2.DataBind();
con.Close();
}
}

But the strings 'frm' and 'sub' returns null values.

Forms Data Controls :: Displaying A Null Or Empty Cell For A Null Datetime Database Value In Gridview?

Dec 6, 2010

I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?

I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.

Forms Data Controls :: Display A One Row Gridview When Gridview Is Bound To Empty Dataset

Jan 13, 2010

If the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template. Since the gridview is empty it won't bind not allowing rendering of the <footer template> I guess I should create a empty dataset if the gridview is empty. How do I check for this and can this be done in GridviewRowEventArgs

Forms Data Controls :: Null Fields After Update In Gridview?

Apr 13, 2010

I have a Gridview showing the data on one of my tables, and when I try to edit the data in one of the columns after I click update, rather than updating the record with the new value I typed in, the rows become null as in, everything in the row I just edited disappears. This inmediatly makes my application crash because one of the fields in my table (IssueDescription) doesn't allows null values.

This is the code, which is actually 100% auto-generated from when I created the GridView control and specified in the options to implement update, delete, edit options.

<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
AutoGenerateColumns="False" DataKeyNames="ticketNum"
DataSourceID="SqlDataSource1" [code].....

What is making the rows turn into null after the update? I did some research and tried to define the Update behaviour myself using RowUpdating function. After hours of learning how to use it I got it to "work", but because the Update turns everything to null when it updates, the sqlconnection command I use to do the query sends null anyways. I can paste the C# code if you'd like to see it, though I'd rather not use it if the auto-generated by asp above can be fixed instead.
