I've created a custom gridview control with a custom datacontrolfield as well, which enabled me to have textboxes in the headercells of the gridview so I can filter each column value.
Now I've added textboxes to the footer row as well so I can allow users to insert data directly from the grid.
As you can see, I added an Insert and Cancel button in the footer row. Then I have my custom column. Now in the rowdatabound event of the grid, i'm trying to hook up the linkbutton click event to a handler:
Code:
Protected Sub nsGrvContainer_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles nsGrvContainer.RowDataBound
Select Case e.Row.RowType
Case DataControlRowType.Footer
Dim lbInsert As LinkButton = CType(e.Row.FindControl("lbInsertCN"), LinkButton)
AddHandler lbInsert.Click, AddressOf odsContainerNumber_Inserting
End Select
I find the control fine, but the click event never fires.

I'm creating a custom gridview control. so far I've been able to add custom sort arrows and an export to excel feature.
Now I want to have a textbox and a button in the header row to filter each row.
I want to extend either the boundfield or boundcolumn class to add a property that will allow me to distinguish wheter the column should have a filter textbox in the header.
I have a Gridview Custom Control (class library project). What I want to do is, add a button to the page. Once the button is clicked, I need a ModalPopupEctender to come up with a checkboxlist of all the Columns in the SQLDataSource that populates the Gridview.
Now since this is a class library project that inherits from the Gridview, I'm not sure how I can add a div at the very top of the page, with the "Choose Columns" button.
Should I create a user control that contains my Custom Gridview? Reason I want to do what I ask is because I want to reuse this in as many projects as I can, I wan this functionality built in to my dll.

I have three web forms to insert, read and edit data. I want to display single records on each page. My pages consist of textboxes, listboxes, and images. I currently achieved reading, inserting and editing using a datareader and parameter queries. I'm wondering the best way, to design web forms. Can i use stored procedures. Using stored procedures; is more secure or not, is more stable or not,
Environment: IIS 5.1 , OS Windows XP, SP3 , I.E 6.0, SQL Server 2008 and Visual Studio 2008I am quite new to development. I developed a small web application on VB.NEUser will login with UserID and Password, select the only Excel file and click 'submit' button. On Submit button, selected Excel file will be transfered from one location to another on network and insert the Excel column data in SQL server 2008.
I recently read Scott Mitchell's article series "Examining ASP.NET's Membership, Roles, and Profile". In Part 6 [URL] It says "to store additional, user-specific fields...If you are using the SqlMembershipProvider, this would mean creating an additional database table that had as a primary key the UserId value from the aspnet_Users table and columns for each of the additional user properties."
I created a table named Thread to store some specific users information and comments they make. I set the ThreadId as the primary key and the UserId as the foreign key to the UserId in aspnet_Users table. But when I run the application and use a user's account to submit a comment, there is an error in my Comments.aspx.vb page "Cannot insert the value NULL into column 'UserId', table 'ASPNETDB.dbo.Thread'; column does not allow nulls. INSERT fails.The statement has been terminated."
How can I make the logged-on user's UserId inserted into the Thread table when storing the user's other data information?

I would like to set the one template for edit/insert and view in my custom FormView control . But i got these odd exception Unable to cast object of type 'System.Web.UI.LiteralControl' to type 'System.Web.UI.WebControls.Table'.
public class CustomFormView : FormView { [PersistenceMode(PersistenceMode.InnerProperty), TemplateContainer(typeof(FormView), BindingDirection.TwoWay)] public IBindableTemplate FormTemplate { get; set; } protected override void OnInit(EventArgs e) { ChangeMode(FormViewMode.Edit); if (FormTemplate != null) { if (CurrentMode == FormViewMode.Edit) { FormTemplate.InstantiateIn(this); } } base.OnInit(e); } } edited : in the first step , I created the new user control and added a formview ("FV") public partial class Form : UserControl { private IBindableTemplate _template = null; [PersistenceMode(PersistenceMode.InnerProperty), TemplateContainer(typeof(FormView), System.ComponentModel.BindingDirection.TwoWay)] public IBindableTemplate FormTemplate { set;get } protected void Page_Init() { if (FormTemplate != null) { FV.InsertItemTemplate = FV.EditItemTemplate = FormTemplate; if (!IsPostBack) FormTemplate.InstantiateIn(FV); } } }
Now , I want to convert this user control to web control.
I am using ASP.Net 4.0/Visual Studio 2010. However, I think it would be the same if it was ASP.Net/VB.Net 3.5. I am inserting three form filed values into a database table. I have placed a LoginName Control on the page and the login name is properly displaying. I am using forms Authentication and it is set up properly in the web config file. I simply want to insert the logged in username value into the database table so I can track who created the records. I am happy to be able to insert the UnserName or the UserID value. I assume both of the values are derived out of the aspnet_Users table. Being able to insert either one would be fine but I believe UserID would be better because it will always be unique.
On my page I am mapping my Sql Server Table fields with Access table fields
Once this is done I want to bulk insert records from Access table to the Sql Table
Also this is not exaclty table to table insert .I should be able to do it on a Button Click where either create a string or Datatable and then run a bulk insert
I have a database with a 1 to many relationship in SQL Server 2008. I have created a formview in VS2008 to insert records into the child table. However I can't set the foreign key to automatically insert this value. If I manually type in a value the insert works but I need it to pick up the fk ID automatically from the master table. How can I do this?
The master table: tblTopic has ID int auto increment primary key and the child table has ID int auto increment primary key and TopicID int allow duplicates no nulls, foreign key. I have set updates to cascade in the relationship.
My insert statement is INSERT INTO tblTopic (TopicID, Comment, SubmittedBy) VALUES (@TopicID, @Comment,@SubmittedBy). The TopicID keeps throwing the error, this is the foreign key.
This is the first time I have tried to do this, so apologies if it's really obvious but I'm on a bit of learning curve.
