I am using a GridView on my ASP.NET form.
Would it be possible to have a GridView with 10 empty rows, having 5 columns.
Can I define the number of GridView Rows I could Edit.
i would then have an Update Button, which would update all the rows to the database.
I'm trying to generate a dropdownlist in a GridView. However, my dropdownlist seem to be empty and I'm not sure how to fix it. Here's my code for the dropdownlist in my GridView & it's SqlDataSource.

SqlDataSource for DropDownList:

.I have a GridView, a PopupExtender and a Button (button is located next to the GridView). The GridView has textboxes and dropdownlists. Initially, the GridView has one empty row (i.e. the textboxes are empty, and the dropdownlist show "blank" option.)When you click on the button "AddFlowButton", a Popupextender shows up, with several textboxes and dropdownlists, and two Buttons ("AddCashFlowButton" and "CancelButton"). Once you fill out the PopupExtender, and click the "AddCashFlowButton" button in the extender, the GridView is populated using the values in the PopupExtender.The problem now is that when I click on the edit button next to a GridView row, the GridView becomes empty, i.e. the textboxes become empty and the dropdownlists show empty values.Here is the code:
ASPX:
<asp:UpdatePanel ID="UpdatePanel3" runat="server">
<ContentTemplate>
<asp:Panel ID="FlowPanel" runat="server" CssClass="modalPopup">
<table>
<tr valign="top">

View 8 RepliesI have a grid view on my page and and i have a datasource for it,
i also included properties like edit/delete and all
Whenever i hit edit i want a dropdownlist instead of a text box ,can we do this?
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.

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.

When select category 1 change on selected index change categary 2 or 3.
In my code I used text box to ediit update delete. but here i will use dropdownlist.
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.Collections.Generic;
using System.Linq;

View 5 RepliesI have a grid view with edit and save buttons when I click on edit it is letting me edit it and if I click on save it is lettingme save the data that I have edited.
The thing is after save is done it is showing the data in edit mode i.e <edit item template > mode I am still seeing the textboxes if I refresh the page then I am seeing it normally.
How can I stop the gridview to show edit mode after the save is done?
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.
