Question

i have an asp.net application in c#.

i have a table in a sql server database with two fields:

Field1
Comments

i need to allow the user to SELECT the Field1 and add comments for that specific Field1

the user would then post the input back to the server

how do i accomplish this? which control can i use? is there already a simple jquery solution?

Answer 1

This completely depends on your site setup. However if you have a list of Field1 values and put them in a DropDownList, you’ll be able to select one and add a comment in a box.

This also heavily depends on your user interface / workflows. This is just one of MANY possible ways to do this.

Code front

<asp:DropDownList ID="ddlField1" runat="server">
    <asp:ListItem>Value1</asp:ListItem>
    <asp:ListItem>Value2</asp:ListItem>
    <asp:ListItem>Value3</asp:ListItem>
    <asp:ListItem>Value4</asp:ListItem>
</asp:DropDownList>
<asp:TextBox ID="tbComments" runat="server" TextMode="MultiLine"></asp:TextBox>
<asp:Button ID="btSubmit" runat="server" OnClick="btSubmit_Click"></asp:Button>

<asp:SqlDataSource ID="sqlRecord" runat="server"
    InsertCommand="InsertRecord" InsertCommandType="StoredProcedure">
    <InsertParameters>
        <asp:Parameter Name="Field1" Type="String" />
        <asp:Parameter Name="Comment" Type="String" />
    </InsertParameters>
</asp:SqlDataSource>

Code behind

public void btSubmit_Click(object sender, EventArgs e)
{
  // Do your validation of the data here
  ..

  // Add fields and insert
  sqlRecord.InsertParameters["Field1"].DefaultValue = ddlField1.SelectedValue;
  sqlRecord.InsertParameters["Comment"].DefaultValue = tbComment.Text;
  sqlRecord.Insert();
}

This is untested and partial pseudo code but should get you in the right direction for a general non-MVC web app. Also this doesn’t use any JavaScript / jQuery, just ASP.NET and C#.
