View 2 RepliesI have a Page, that has UserControl1.
UserControl1 has UserControl2.
When the page loads UserControl2's Load event is not fired at all.
Actuall i retrive one row from Database with more than 80 columns on page load. Now i need to fill these data in every control like Text-Box and Combo-Box which i have using on the Page.
My Column Name and My Id of the Textbox or combobox are same. now i need to fill the value in textbox and combobox where coumn name and textbox id are same.
Eg.
(1) TextBox Id's Name :- txtCustName, txtCustNo, txtAddress, etc(More than 80 Column).
now i will be remove the 'txt" from every id.
so it would be seems like CustName, CustNo, Address, etc.
(2) Column Name :- CustName CustNo Address
Values from (Dataset) :- Xyz 123 Abc.......

I have been building web apps for a while now and still do not know the answer to this.
I have just built a web app (using webforms) which has a page for inserting a new budget request and a page to edit and manage this budget request.
What is a pain is if I have to make changes to the business logic then I need to edit same / similar code in two places.
What I am thinking of doing is creating one page to handle this with only UPDATE logic and if the URL on page load has no ID parameter then create a blank row in table and use this new ID and then UPDATE.
Is this bad practice? I obv know I need to clear out old blank rows at some point.
I have all the code to save and all the code to validate. My question is will my code in the button(.aspx.vb) validate if my insert command is in the .aspx
View 3 RepliesI have a details view to insert some data. I want to validate this data myself. use the ItemCommand to trap the insert command. If the data entered does not match what I need, I want to somehow stop the insert procedure at this point.
View 3 RepliesMy web form contains a detailsview control that I have added a templated field to with a DropDownList in the InsertItemTemplate. The DetailsView default mode is 'insert. My detailsview is attached to a sqldatasource that has a stored procedure in the db to handle the insert. When I enter data in the fields and select insert all values from the detailsview are written to the table except for the selection that was made in the dropdownlist. I am using the ddl.selecteditem.value to populate my variable however when the insert method is envoked it doesn't send my value. The DDL value that I am capturing does not need to be written to the table it is just a flag for some variables that need to be set at the stored proc level. How do I get the DDL selected value to be sent with the insert statement?
Here is my code behind:
Protected
Sub
DropDownList1_SelectedIndexChanged(ByVal sender
As
Object,
ByVal e
As System.EventArgs)
Dim temp
As DropDownList
Dim AccessLevel
As
String
temp = AddUserDetailsView.FindControl("DropDownList1")End
Sub
AccessLevel = temp.SelectedItem.Value
Label1.Text = AccessLevel

I've added a simple SqlDataSource to my site with insert properties. I've also created some code behind to capture the insert command (oninserting="SqlDataSource_NewsLetterSubscription_Inserting").
Thing is how do I actually trigger the command to 'insert' from a standard button?
<asp:SqlDataSource ID="SqlDataSource_NewsLetterSubscription" runat="server"
I would like to know if I can do the following: when I am in insert mode, can I dynamically change the select command of and then display that result in the second dropdownlist based on what was selected in the first dropdownlist.
I would like to include the minimum code to demonstrate what I am trying to do.
