Gridview with dynamically created checkboxes.........

I have a rather large gridview (70+ columns) that I'm creating dynamically based on query results. Without using a template column, I would like to create a check box for each row of data so that a user may select one or multiple rows of data. Is that possible without using the template column?

If possible...can anyone share any links and/or code (VB please)

Why is it necessary to NOT use a template column? This is what they are ment for.

I've tried using the template column, but I'm still getting funky results. Currently, I'm creating the grid on the fly:

For Each dc In MyDataConnections.m_DAL.DataSet.Tables("table_of_Main_Data").Columns
Dim bfield As New BoundField

bfield.DataField = dc.ColumnName
bfield.HeaderText = dc.ColumnName

grdTableDetails.Columns.Add(bfield)

grdTableDetails.DataSource = MyDataConnections.m_DAL.DataSet.Tables("table_of_Main_Data")
grdTableDetails.DataBind()

This code works and I bind my data....my grid shows up.....I see a spot for the checkbox (eg...an additional column at pos(1), but there is no checkbox in said column?

I've tried running the additional code after the bind:

Dim tccheckcell As New TableCell
Dim checkbox = New CheckBox
tccheckcell.Controls.Add(checkbox)
grdTableDetails.Rows(1).Cells.AddAt(1, tccheckcell)

which makes the checkbox show up, but it offsets all of my data to the right (eg...headers stay in the same position, but the row data moves over one space)

Hi,

I ve done this without using template column in aspx page.

But somehow u have to use codebeind to dynamically check box/dropdowns uinsg .cs file have a look

void ITemplate.InstantiateIn(Control container)
        {
            DropDownList cmd = new DropDownList();
            //cmd.AutoPostBack = true;
            cmd.ID = "cmd";
            //cmd.SelectedItem.Value = "HI";
            cmd.Items.Insert(0, "Present");
            cmd.Items.Insert(1, "Absent");
            cmd.Items.Insert(2, "Week OFF");
            cmd.SelectedIndexChanged += new EventHandler(Dynamic_Method);
            container.Controls.Add(cmd);
        }
        protected void Dynamic_Method(object sender, EventArgs e)
        {
        value = (DropDownList)sender).SelectedItem.Value;//u can use checkbox as well
       
        }
TemplateField TmpCol = new TemplateField();
                    TmpCol.HeaderText = dls[i].ToString();
                    gv.Columns.Add(TmpCol);
                    TmpCol.ItemTemplate = new TemplateHandler();

You can use the checkbox to achive the same.. Its bit tedious and time consuming but still u can achive. You would not find so many blogs answering this as this requirement is complex and needs observation by techy

Why do you need to build the grid dynamically?

Re: Gridview with dynamically created checkboxes.........

I have multiple datatables feeding the one grid.......some tables return more columns/rows than the other (depends on what the user is looking for).....didn't want to get tied down creating boundfields dynamically or creating template based grids. Plus with a variety of columns/rows its easier to format them when done dynamically
