Setting Values For Invisible Fields / Properties In DetailsView?
Mar 16, 2011I have a DetailsView which has two fields - one that is visible, one that is not. The first the user fills out, the second I want to auto-populate. Unfortunately, I haven't been able to find a way to set the value in this second invisible field. I've tried adding code like this to the Page_Load:
If Not IsPostBack Then
DetailsView1.DefaultMode = DetailsViewMode.Insert
Dim txt1 As TextBox = DirectCast(DetailsView1.FindControl("Type"), TextBox)
txt1.Text = "administrator"
End If
But this returns an error of "Object reference not set to an instance of an object." how to accomplish this - either using the method above or another method? The hoped for end result is that when a new record is inserted via the DetailsView that this record will include the username (entered by the user) as well as the "type" of "administrator"

Invisible Borders In HTML Table Not Quite Invisible?
Sep 11, 2010I have some tables in my asp.net mvc application for layout purposes. Even though I usually use divs for most things, in some cases tables make most sense because they already have exactly the layout I'm after in these cases.
The only problem is, as far as I know the borders are supposed to be invisible unless you specify a width and style for the borders. But they aren't... They are rather vague, yes, but there are still light blue borders around each cell. What is that and how do I get rid of them? (Funny thing is I don't remember having seen this before when I used tables, which was a while ago).
I also tried specifically setting the border to 0px on both table and td, but that didn't work either...

View 4 RepliesWeb Forms :: How To Access Web Control Values
Mar 21, 2010I am developing a site that has a page and several web controls.
Say i have webControl1.ascx, webControl2.ascx, webControl3.ascx, webControl4.ascx
I add these web cotnrols dynamically webControl1.ascx webControl2.ascx and some other times webControl3.ascx webControl4.ascx
Lets say webCotnrol1.ascx has an aspx button with ID="SaveArticle" and click event "MyClickEvent". If i press this button i am suppose to load webControl3.ascx webControl4.ascx but not webControl1.ascx webControl2.ascx.
The first problem is that "MyClickEvent" will never execute since the webControl1.ascx will never be loaded.
The second problem is that i tried to use FindControl("SaveArticle") but these does not work since the name is changed to something like "$articleControl$SaveArticle"
I think my problem is that i dont know how to hancle workflow.
Using Checkbox From The Calendar Control - Able To Access The Values
Feb 26, 2011I am implementing a leave system using the calender control. Something like below :- Following is the markup :-
<asp:Calendar ID="Calendar1" runat="server" ondayrender="Calendar1_DayRender"
ShowGridLines="True">
</asp:Calendar>
<asp:DropDownList ID="DropDownList1" runat="server">
<asp:ListItem Value="vacation" Text="Vacation" />
<asp:ListItem Value="sick" Text="Sick" />
<asp:ListItem Value="training" Text="Training" />
</asp:DropDownList>
<asp:Button ID="Button1" runat="server" Text="Save" onclick="Button1_Click" />
Following is the code-behind :-
protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
if (!e.Day.IsOtherMonth && !e.Day.IsWeekend)
{
CheckBoxList list = new CheckBoxList();
list.Items.Add(new ListItem("Half day"));
list.Items.Add(new ListItem("Full day"));
e.Cell.Controls.Add(list);
}
}
However, I am not able to access the the checkbox values neither in the button_click event nor in the DayRender event? Is there a better way to implement this?

Data Controls :: How To Make A Column Invisible In GridView Control
Jan 25, 2013I bound the gridview having some fields(ID, StudName, City) and Display Button. When I click on the Disply button I approve the student and updation will happen.
Bu what happen the column ID is not in the sequence. Sometime it displays 1,2,3,4,5,6 ... next time it will display 7,8,9,10,11.... I want a sequence for the column ID. For that I used :
<%# Container.DataItemIndex+1 %>
and it is working fine.. But again I realize that these numbers are generating at runtime and i can't refer to that student. Also I don't want to display ID column on the grid view but I want to use on runtime generated column. [ i am using RowCommand for ID column ] How it is possible?

Access :: Insert Records Into Access (not Inserting Null Values)?
Nov 12, 2010I have a SQL database. I am getting a datatable from SQL. In SQL Query the table is having null values in the output. But when it is coming to the front end, the null values are replaced by empty values.
So in the front end in the datatable i am having empty values in some cells. I am trying to insert this datatable into access. For this i am using following code...
OleAdpData.InsertCommand.Connection = OleConn; // OleConn is the OleDbConnection
OleAdpData.InsertCommand.Connection.Open();
OleAdpData.Update(dtData); // dtData is the datatable
OleAdpData.InsertCommand.Connection.Close();
It is inserting the datatable to access database. But it is inserting the empty spaces as present in the datatable. I want to insert NULL into the cells in access datatable where the cells are empty. Where should i add my logic for this.
