Set current date in formview

Set current date in formview - c#

I want to put the current date in my formview 'dateadded' but its not showing when I load it in the browser. I'm using code behind but how can I display it with date and time?
Here's a my code behind.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace LibrarySystem.AdminPage
{
public partial class ManageBooks : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if(FormView1.CurrentMode == FormViewMode.Insert)
{
TextBox dateadded = FormView1.FindControl("dateaddedTextBox") as TextBox;
dateadded.Text = DateTime.Now.ToString("d");
}
}
}
}
Here's my complete design

You have to use the Databound event for that...
protected void FormView1_DataBound(object sender, EventArgs e)
{
if (FormView1.CurrentMode == FormViewMode.Insert)
{
TextBox dateadded = FormView1.FindControl("dateaddedTextBox") as TextBox;
dateadded.Text = DateTime.Now.ToString("d");
}
}
Edit: You need to pass your Date Column in the inserting method of the DetailsView
protected void DetailsView1_ItemInserting(object sender, DetailsViewInsertEventArgs e)
{
e.Values["DateColumnName"] = ((TextBox)DetailsView1.FindControl("dateaddedTextBox")).Text;
}

Instead of doing that in your Page_Load() method, try doing it in the Page_PreRender() method.

With the above code I get the error constantly.
In SQL if I run the SqlDataSource2 query I get results (ID and State).
I tried Changing my queries and editing my dragged SqlDataSource2 in the query builder.
As soon as I click on the commandfield "EditImageUrl" I get the above error.
Maybe I am looking at my code to long to notice any issues.
I have googled it with no luck looking at stuff like:
I have looked at Here
And the same here, I have bind instead of Eval in the dropdown list.
I also tried changing my sqldatasource to:
Select * from State
Select ID, State from State
Select ID, State from dbo.State
Any help will be appreciated.

Edit and Update
In EditTemplate you fill in aspDropDown from SqlDataSource2 with correct DataTextField="State" DataValueField="ID". But SelectedValue belongs to <asp:SqlDataSource ID="dsCustomerTickets". So you need T.State in SelectCommand to make binding SelectedValue='<%# Bind("State") %>' correct. Also there is no need in Bind in ItemTemplate. Eval("State2") is enough.
And 1st SqlDataSource should be
<asp:SqlDataSource ID="dsCustomerTickets" runat="server"
ConnectionString="<%$ ConnectionStrings:TicketsSupportConnectionString %>"
DeleteCommand="DELETE FROM [Tickets] WHERE [ID] = #ID"
InsertCommand="INSERT INTO [Tickets] (/*removed for shortness*/ [State]) VALUES ( #State2)"

asp.net c# DetailsView DropDownList fails to Update

I've created a DetailsView that displays data based on a selected item from a GridView. When the DetailsView is under Edit Mode, it displays dropdownlists that contain data from a SQL databind. The data displays in the dropdownlist without issue, but fails to update. All other fields succeed.
The data is bound to the drop down via OnDataBound.
The idea is to populate the SelectedValue with the current data, and populate what it can be changed to. This works without issue. It simply fails to update.
I believe it has to do with syncing the control with the "an" parameter, but am at a loss at how to do so.

Your update command appears to be part of the details view, and not part of any ObjectDataSource. Can you confirm your markup above is correct?
Edit
In your UpdateParameters group, you aren't getting the values from the controls. Try doing the following:
<UpdateParameters>
<asp:Parameter />
...snip
<asp:ControlParameter Name="an" ControlID="idOfWhateverControlHasTheUserSetValue" Type="String" />
...snip
</UpdateParameters>

I took your advice and did a little research about using the ControlParameter.
The fix was adding the following to the Update Parameters, and removing the auto-populated parameters for 'an'. Thanks for the help, Nick.
<asp:ControlParameter Name="an" ControlID="userDetails$anEditDD" PropertyName="SelectedValue" Type="String" />

grid view won't update database (no errors)

I have a page with a details view and a grid view (each with their own data source. I can't figure out why the update says it's successful but don't update the table. the details view works fine.

You should pass the proper parameters to the UpdateParameters section. It looks like you have a copy-paste problem (maybe you copied the section from the InsertParameters section). Your UPDATE statement needs only 3 parameters.

Casting object to CheckBox in bulk updates

I was following this so far everything is fine with a textbox but when try to modify it to checkbox it gives an error: Unable to cast object of type 'System.Web.UI.WebControls.TextBox' to type 'System.Web.UI.WebControls.CheckBox'.
Its working when I use TextBox but how can I make all the CheckBox editable in bulk updates?
Here's the sample code behind
private bool tableCopied = false;
private DataTable originalDataTable;
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
if (!tableCopied)
{
originalDataTable = ((DataRowView)e.Row.DataItem).Row.Table.Copy();
ViewState["originalValueTable"] = originalDataTable;
tableCopied = true;
}
}
protected void UpdateButton_Click(object sender, EventArgs e)
{
originalDataTable = (DataTable)ViewState["originalValueTable"];
foreach (GridViewRow r in GridView1.Rows)
if (IsRowModified(r))
{
GridView1.UpdateRow(r.RowIndex, false);
}
tableCopied = false;
GridView1.DataBind();
}
protected bool IsRowModified(GridViewRow r)
{
int currentID;
string currentreservedate;
string currentisapproved;
currentID = Convert.ToInt32(GridView1.DataKeys[0].Value);
currentreservedate = ((TextBox)r.FindControl("reservedateTextBox")).Text;
currentisapproved = ((CheckBox)r.FindControl("isapprovedCheckBox")).Text;
DataRow row = originalDataTable.Select(String.Format("reservationid = {0}", currentID))[0];
if (!currentreservedate.Equals(row["reservedate"].ToString()))
if (!currentisapproved.Equals(row["isapproved"].ToString()))
{
return true;
}
return false;
}
}
}
Here's the aspx markup

<asp:SqlDataSource ID="SqlDataSource1" runat="server"

Help would be much appreciated! Thanks in advance!

I think that to answer this question, the contents of the aspx file are required, but I'll try to help. More than likely the element in your form, isapprovedCheckBox, is still set to the the tag asp:Text. As a result the system can't convert the textbox to a checkbox.
Could you include your aspx content as well?
