code behind - variables and gridview-selected data

Posted By:      Posted Date: October 11, 2010    Points: 0   Category :ASP.Net


I'm a newbie using VWD 2010 Express, asp.net 4.0.  

I'm also learning VB and C#.  I'm pretty lost, so please direct me. 

I'm trying to understand the code-behind behind gridview select/edit buttons.  I'm not sure whether I need to look for asp.net or VB/C# tutorials. 

   protected void ds_Selecting(object sender,SqlDataSourceSelectingEventArgs e)

Using above example, 
1. How do I access the user-selected row data from the gridview in the code-behind? 
2. What is 'sender' and 'e'? 

If there's a tutorial that explains these, please direct me.

Thank you!

Rendering data with HTML tags in the DD Gridview for a selected column


I am having trouble finding out where and how to HTML Encode a cell's data on the Dynamic Data (v4.0) gridview of List.aspx.  As a simple case, suppose I have formatted cell data that is A<br/>B in the DB.    Obviously, I want A stacked on B in the cell.

It seems gridView1.HtmlEncode = true has gone away.

So maybe I'll try to catch it on the RowDataBound event:

protected void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e)

            if (e.Row.RowType == DataControlRowType.DataRow)
                // Html Encode the cells


but this event never fires?

Has anyone figured out how to properly render HTML tags data in the List.aspx's GridView1? 

If I figure this out, then I can add a MetaAttribute called something like [EncodeAsHtml(true)] and be on my way.  Thanks!

Gridview row sometimes has to be selected twice for code to work


I'm using the code below to extract data from a gridview and populate it into textboxes for the days and two drop downs for Project and Category.

For some rows in the gridview everything but the category ddl populates correctly. If I click the row a second time the category ddl displays the correct category.

Can anyone tell me why I have to click twice for some rows? And how do I fix this?

Thank you

protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
    //// Get the currently selected row using the SelectedRow property.
    GridViewRow row = GridView1.SelectedRow;

    txtSunday.Text = (row.Cells[6].Controls[0] as DataBoundLiteralControl).Text.Trim();
    txtMonday.Text = (row.Cells[7].Controls[0] as DataBoundLiteralControl).Text.Trim();
    txtTuesday.Text = (row.Cells[8].Controls[0] as DataBoundLiteralControl).Text.Trim();
    txtWednesday.Text = (row.Cells[9].Controls[0] as DataBoundLiteralControl).Text.Trim();
    txtThursday.Text = (row.Cells[10].Controls[0] as DataBoundLiteralControl).Text.Trim();
    txtFriday.Text = (row.Cells[11].Controls[0] as DataBoundLiteralControl).Text.Trim();
    txtSaturday.Text = (row.Cells[12].Controls[0] as DataBoundLiteralControl).Text.Trim();

    // Set ProjectList ddl to Project in selected row

Editing the Data in a GridView

In addition to deleting a GridView's underlying data, another common need is to allow end users to edit the data displayed in a GridView. With ASP.NET 1.x's DataGrid control, editing the data is certainly possible, but requires creating three event handlers and writing a dozen or so lines of code. With the GridView and ASP.NET 2.0, it is possible to create an editable GridView without writing a single line of code! All of the necessary functionality is encapsulated within the GridView.

The GridView allows editing on a row-by-row basis. An editable GridView contains an additional column with an Edit button in each row. When the end user clicks on an Edit button that row becomes editable, causing the Edit button to change to Update and Cancel buttons and the other columns to become TextBoxes. The end user can then update one or more column values and click Update to save their changes.

Easily manipulate data with the GridView control in ASP.NET 2.0

Last week, I introduced ASP.NET 2.0's GridView data control and covered the basics of using it. This week, I go a step further by going into the details of working with the data contained in the control. This includes viewing, editing, and deleting data. Thankfully, the GridView control makes it easy to utilize these features. Before diving into these topics, I begin with an examination of the different field types supported by the GridView control.
