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;

Here is a snippet of my code...
<ItemTemplate>
<asp:LinkButton
ID="lbEdit"
runat="server"
CommandName="Edit"
>Edit</asp:LinkButton>
<asp:LinkButton
ID="lbNew"
runat="server"
onclick="lbNew_Click"
CommandName="New">New</asp:LinkButton>
</ItemTemplate>
Code behind...
Protected Sub gvPunches_RowEditing(ByVal sender
As
Object,
ByVal e
As System.Web.UI.WebControls.GridViewEditEventArgs)
Handles gvPunches.RowEditing
Dim i
As
Integer = e.NewEditIndex()
Dim ddl
As DropDownList =
CType(gvPunches.Rows(i).FindControl("ddlDiv"), DropDownList)
the question I have is when i enter this procedure in the code behind, ddl is nothing. what am I doing wrong in populating the dropdown for the row I am editing?

What I have is a GridView with a DropDownList in an ItemTemplate (not an EditItemTemplate). My datasource is not a control, rather in the code-behind.
[Code]....
My main problem is that VS is not seeing that I have the dropdownlist, meaning I can not access any of the events in the code-behind. What I want to do is, when the value of the DropDownList is changed (SelectedIndexChanged), I want to grab the value of the RowIndex of the GridView.

during edit mode i populate the drop down in question with data based on a value selected in another drop down also in the gridview, all works find, but the paramater is not being updated with the selected value, i think this is because i do not call any Bind in the aspx side.
<asp:TemplateField HeaderText="Build Types">
<ItemTemplate>
<asp:Label ID="lblBuildTypes runat="server" Text='<%# Bind("BuildType") %>'></asp:Label>
</ItemTemplate>

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.
<asp:SqlDataSource
ID="SqlDataSource1"
runat="server"

ConnectionStrings:BlazeBillzConnectionString %>"
SelectCommand="SELECT
[Prod_Sold_ID], [Order_Date], [Billing_Period] FROM [ProductsSoldTable] where Prod_Sold_ID < 130"

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?

I have gridview that has month as a column. When the user clicks a row's edit button, that row goes into edit mode. I have created a drop-down list for month in edit mode with the values 1-12. Right now, the drop-down list shows 1. I would like it to show the current value for that row. How do I do this? Here's the code for my gridview:

This is my first post on this forum. I have a Gridview with the following Columns
1. Edit Column
2. User_ID (Read Only)
3. Email (Read Only)
4. Role ( A Dropdownlist with 2 list Items namely "Admin" & "QA Lead")
I have used wizard to populate a "Gridview" and the embedded "Dropdownlist" control in it. This is my reference: [URL] My Problem: The Data populates perfectly in Grid and Dropdownlist. But, when I Press "Edit" button the Dropdownlist goes into edit mode in the form of a "Texbox". (i dont want this) I still want it to be an editable dropdownlist.

I have a Gridview showing the MemberLastName, MemberFirstName, MemberBirthYear, MemberGender, MemberRelationship.
During Edit mode, I have managed to display a DropDownList for the Relationships.What I am trying to achieve now, is that, based on the Gender of the member I would like to limit the items in the Relationships dropdownlist.
e.g if the Gender is Male, then only display Male Relationships
What is the best way to achieve this scenario?Here is my snippet of code for the event. The code is commented out as it throws an exception.

I have the following ListView (extra code removed for clarity) :
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<EditItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</EditItemTemplate>
<InsertItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</InsertItemTemplate>
</asp:ListView>
The Insert row in the ListView has an empty DropDownList and GetCountries() is not called. However, if I click the Edit button on an existing row, GetCountries() is called twice (not sure why) and the DropDownList is properly populated. Why isn't the InsertItemTemplate DropDownList getting populated?

On my formview I have a drop down list that is populated with the names of the files in a certain directory. This works fine, but when the drop down list selected value is bound to the database field I get the following error :
'ImageFileDropDownList' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
I have setup other drop down lists in the same formview populated from SqlDataSources and these all work fine. I can see perhaps why this is an issue because I have not specified a DataValueField or a DataTextField for this drop down that is populated in code (whereas I can for the SQL bound ones) because I'm not sure what these settings would be.
I need to have a "blank" option as well so that the field does not default to the first value in the list.
