Insert Command in a Gridview - asp.net

Question

I am trying to execute an "INSERT INTO" command by using the asp:SqlDataSource InsertCommand in a C# statement ".Insert()".
The Button, "btninsert", resides in the header field of a gridview as does the inserting Textboxes: "TextBoxHeadercol1", "TextBoxHeadercol2" and "TextBoxHeadercol3".
I have 4 columns in my table, "test", they are "idt", "col1", "col2", "col3". My Gridview is "gvtotal".
I know that col1, col2 and col3 will print no data because I left out ItemTemplate with the labels.
public void btninsert_Click(object sender, EventArgs e)
{
SqlDataSource1.InsertParameters["col1"].DefaultValue = ((TextBox)gvtotal.HeaderRow.FindControl("TextBoxHeadercol1")).Text;
SqlDataSource1.InsertParameters["col2"].DefaultValue = ((TextBox)gvtotal.HeaderRow.FindControl("TextBoxHeadercol2")).Text;
SqlDataSource1.InsertParameters["col3"].DefaultValue = ((TextBox)gvtotal.HeaderRow.FindControl("TextBoxHeadercol3")).Text;
SqlDataSource1.Insert();
}
<asp:GridView ID="gvtotal"
runat="server"
DataSourceID="SqlDataSource1"
AutoGenerateColumns="False"
DataKeyNames="idt">
<Columns>
<asp:BoundField DataField="idt" HeaderText="idt" Readonly="true" SortExpression="idt" />
<asp:TemplateField SortExpression="col1">
<HeaderTemplate>
<asp:TextBox ID="TextBoxHeadercol1" text="col1" runat="server" MaxLength="40" />
</HeaderTemplate>
</asp:TemplateField>
<asp:TemplateField SortExpression="col2">
<HeaderTemplate>
<asp:TextBox ID="TextBoxHeadercol2" text="col2" runat="server" MaxLength="40" />
</HeaderTemplate>
</asp:TemplateField>
<asp:TemplateField SortExpression="col3">
<HeaderTemplate>
<asp:TextBox ID="TextBoxHeadercol3" text="col3" runat="server" MaxLength="40" />
</HeaderTemplate>
</asp:TemplateField>
<asp:TemplateField>
<HeaderTemplate>
<asp:Button ID="btninsert" runat="server" Text="Insert Into" OnClick="btninsert_Click" />
</HeaderTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:SqlDataSource
id="SqlDataSource1"
ConnectionString="<%$ ConnectionStrings:connone %>"
SelectCommand="SELECT * FROM [test];"
InsertCommand="INSERT INTO [test] [col1],[col2],[col3] VALUES #col1,#col2,#col3;"
runat="server"
/>

I think you might get away with this by using InsertCommand template provided by SQLDataSource. Write this command for SQLDataSource for
InsertCommand = "INSERT INTO Test(….) VALUES(#val1,#val2,#val3)
Use SQLDataSource template to map #val1, #val2 and #val3 to text boxes you want. The provided quick template will facilitate this. In the click event for Insert, simply refresh grid view view to display the new contents
public void btninsert_Click(object sender, EventArgs e)
{
gridview.DataBind();
}
