Forms Data Controls :: Gridview With Dropdownlist Edit / Getting An Error

Jan 6, 2010

I have create a grid view with a dropdownlist for one of the columns. This works fine, but when I click edit and then update I get an error saying it cant update due to null value. I'm sure it because the parameter in the update of SqlDataSource1 is not referring to the value select in the edit item template, but I cant figure out how to do this.

My code is below.

Forms Data Controls :: GridView Edit Fails On DropDownList

Jun 30, 2010

I have created a Gridview (using ObjectDataSource) for Edit/Updates. I am getting an error on my DropDownList which is configured with the list items Yes and No only for both text and values.

Most of my data in my SQL table has values of either Yes or No, however there are some records that are BLANK or even NULL sometime.These rows fail in my GridView when attempting to Edit.

I tried going into the DDL Edit List items and adding a Blank with and empty value however each time i try to save the page VWD removes it.

How do i account for reverse lookups of all possible values Yes/No/Blank or Empty/NULL in my DDL?

Data Controls :: Populating DropDownList In Edit ItemTemplate Of GridView?

Aug 29, 2013

I read your article on ASPSnippets and everything worked great.  I am having one problem and this is preventing me from moving forward.  When I select the edit for a row (I only have two columns), the drop down comes back blank (no records).  I have looked at the code multiple times and can't see where I made a mistake. is it possible to control the width of the drop down list?  I can't tell if the column automatically adjusts because I am not returning any records.

using System;
using System.Collections.Generic;
using System.Linq;

Can someone tell me if there is a technique to make an entire Column within an gridview (for example digits) editable (instaed of a single row) and update this column after changing values by press an Update-button?

A commercial solution is also o.k. with me, but, of course, a method to do it ourselve would be nice.

Forms Data Controls :: Master Detailed GridView Edit Selects The Wrong Row To Edit?

Mar 16, 2011

I have a page with 2 GridViews on it. The top GridView shows all the Bike Riders the bottom GridView shows all the Bike Lockers. I have set up both GridViews to be able to Edit the data. And the top GridView to Select.

When I click the Select buton on the top GridView I programically reset the DataSource for the bottom GridView to show the Locker for the Biker of the top GridView Selected.

So far everything works great. I select a Biker on the Top GridView and the Bottom GridView resets just showing one record for the bike locker.

The problem is that if I then click on the Edit button on the bottom GridView (The Bike Locker GridView) the GridView goes into the Edit Mode but it now shows all the Bike Locker records and the edit record is always the top record of the GrdView.

Here is my code Behind:

Forms Data Controls :: Dropdownlist In The Edit Template

Aug 24, 2010

I have a transaction table with a field called product. There is a limited number of choices for product so I also have a product table. I am showing the transactions in a ListView with a dropdownlist for Product. The field Product can be blank (all works well then). The user can leave the field blank or they can choose from the dropdownlist. I am running into a problem with the dropdownlist in the Edit Template. No matter what the product is in the transaction file, I get a page error of "ddlEditProduct has a SelectedValue which is invalid because it does not exist in the list of items". I have verified the product does exist in the product table.

<asp:DropDownList ID="ddlEditProduct" runat="server"
DataSourceID="dsProduct"
DataTextField="Product"
DataValueField="Product"
AppendDataBoundItems="true"
SelectedValue='<%# Bind("Product") %>' >
<asp:ListItem Selected="True"></asp:ListItem>
