DateTime search problems ASP.NET

DateTime search problems ASP.NET - c#

I have a database that stores lottery form submissions from users. One of the columns is a DateTime column that is populated with the current DateTime every time someone submits a form. I want to be able to search by the DateTime column so I can pull up all the forms entered on a particular day.
I'm not getting any errors when I perform the search, just my custom message that "No results matching that search criteria". I've tried disabling the jquery datepicker and tried copying and pasting the exact DateTime field from the DB into the search box and still nothing. Obviously I'm missing something but I can't figure out what. Any help is much appreciated.

In SQL, you state that you are storing the data as a DateTime. This means you are getting the date and the time. Of course the time includes hours, minutes, seconds, etc...
In you query you need to CAST your DateTime to a Date in order to remove the time from it.
See this MSDN article for more clarification https://msdn.microsoft.com/en-us/library/ms187819.aspx

Add New Row in GridView cannot find reference

I have an editable GridView but I would also like to have an add new row functionality, so I made a button using FooterTemplate for all editable fields and set CommandName="AddNew" . Everything looks as expected on the front end, but Add New Row cannot find txtGrantId, txtPotId or txtBudget at all and throws System.NullReferenceException 'Object reference not set to an instance of an object.'. The issue has to be in the code behind, but I am attaching the front end as well. The data source is pretty long but it does call OnRowCommand="gvPotsMoneyGrants_RowCommand"

Understanding Gridview RowCommand

I've coded a gridview that doesn't fire when I click the edit button and I found an older question that addresses my issue by just using e.CommandName with if statements under the RowCommand method. I'm trying to figure out how to implement it with my code.
My question is, how do I use e.RowIndex during update to find my controls and reference those now? Also, I've tried calling my old Update method but it won't let me use sender and e as parameters because GridviewCommandEventArgs is different from GridViewEventUpdateArgs. I'm pretty lost, any help would be appreciated in straightening this out.
C#:
void RowCommand(Object sender, GridViewCommandEventArgs e)
{
// If multiple buttons are used in a GridView control, use the
// CommandName property to determine which button was clicked.
if (e.CommandName == "Edit")
{
}
if (e.CommandName == "Update")
{
UpdateCustomer(sender, e);
string nFirstName = ((TextBox)GridView1.Rows[e.RowIndex].FindControl("txtFirstName")).Text;
string nLastName = ((TextBox)GridView1.Rows[e.RowIndex].FindControl("txtLastName")).Text;
string nEmergency = ((TextBox)GridView1.Rows[e.RowIndex].FindControl("txtEmergency")).Text;
string nCell = ((TextBox)GridView1.Rows[e.RowIndex].FindControl("txtCell")).Text;
string nAge = ((TextBox)GridView1.Rows[e.RowIndex].FindControl("txtAge")).Text;
string nActivityCard = ((TextBox)GridView1.Rows[e.RowIndex].FindControl("txtActivityCard")).Text;
string nBoat = ((TextBox)GridView1.Rows[e.RowIndex].FindControl("txtBoat")).Text;
string nInitials = ((TextBox)GridView1.Rows[e.RowIndex].FindControl("txtInitials")).Text;
string nGroup = ((TextBox)GridView1.Rows[e.RowIndex].FindControl("txtGroup")).Text;

You can pass RowIndex as CommandArgument for your LinkButtons.
<EditItemTemplate>
<asp:LinkButton ID="lnkUpdate" runat="server" CommandName="Update" CommandArgument='<%# Container.DataItemIndex %>'>Update</asp:LinkButton>
<asp:LinkButton ID="lnkCancel" runat="server" CommandName="Cancel" CommandArgument='<%# Container.DataItemIndex %>'>Cancel</asp:LinkButton>
</EditItemTemplate>
Which can be access from code behind. Using rowindex you can get hold of the current row and find any controls using FindControl
void RowCommand(Object sender, GridViewCommandEventArgs e)
{
int rowindex = Convert.ToInt32(e.CommandArgument);
if (e.CommandName == "Update")
{
....
}
if (e.CommandName == "Cancel")
{
....
}
}

e.CommandArgument will contain the index of the row clicked, so you can access the relevant controls via
int index = Convert.ToInt32(e.CommandArgument);
GridView1.Rows[index].Controls[x];

Using identifier in gridview

First specify DataKeyNames="PersonID" for your gridview definition.
Here is how you get the PersonID value in your UpdateCustomer function in code behind.
protected void UpdateCustomer(object sender, GridViewUpdateEventArgs e)
{
// assuming that the value of your PersonID is numeric value
long personID = long.Parse(GridView1.DataKeys[e.RowIndex].Values["PersonID"].ToString());
....
}
The personID value you can pass as an argument to your WHERE clause.
Alternatively you can declare a HiddenField in your gridview and bind PersonID which you can access in you UpdateCustomer function using FindControl method.

What am I doing wrong that the update will not happen? And why am I not getting any errors thrown when it does not update?

Because you are not executing your query.
Try with
command.ExecuteNonQuery();
or you need to set the UpdateCommand property of DataAdapter
da.UpdateCommand = command;
