Web Forms :: Managing MySQL Data In GridView?
Jan 30, 2011
I finally got a GridView to display MySQL Data. Now however I need:1) To edit the way the data is displayed. When my DateTime is grabbed from the MySQL Db, it is displayed like so { 22/01/2011 15:45 } but really I need it like so { 22 Jan 2001 - 15:45 }.2) To Enable Edit, Delete andUpdate of each row of the data. when I go in design view and click on the gridview, I don't get them options, where as on SQL Server 2008 I did.I did some google searching on editing the way a date time is presented, but all I got were results for the function DateTime.Now ..etc which is not what I'm after really.

I have a MySQL database, and I'm currently creating an ASP.NET website to update data in it. I'm currently having trouble changing the data with GridView. Reading through various posts on this site, i think I've got a problem with binding the data, but I'm not sure how to accomplish this with MySQL database. My c# code is as follows:
[Code]....
My asp code is as follows:
[Code]....
At the moment I'm getting an error about the "trash" data, it's an Int32 field, but I'm not sure how to handle that.

I am a new user of ASP.NET 2.0 (VB.NET)
I am facing a problem related to GridView Control
I have a table <UsersDetail> with following structure in MySQL
FIELDNAME | DATATYPE
---------------------------------------
userid | Numeric
Userlogin | Varchar(25)
Userpassword | Varchar(25)
Firstname | Varchar(50)
Lastname | Varchar(50)
---------------------------------------
I wrote a code to fetch data from this table :
Dim Con As New MySqlConnection
Dim Cmd As New MySqlCommand
Dim Adp As New MySqlDataAdapter
Dim DTable As DataTable
Con.ConnectionString = ConfigurationManager.ConnectionStrings("dbConString").ConnectionString
Cmd.CommandType = CommandType.StoredProcedure
Cmd.CommandText = "sp_FetchAllUsers"
Cmd.Connection = Con
Adp = New MySqlDataAdapter
Adp.SelectCommand = Cmd
DTable = New DataTable
Adp.Fill(DTable)
GridView1.DataSource = DTable
GridView1.DataBind()
Basically Gridview controls is used to display data in tabular format.
but due to requirement I changed its layout to columner in following manner
<asp:GridView ID="myGridView" runat="server" AutoGenerateColumns="false" AllowPaging="True" PageSize="3" Width="520px">
<Columns>
<asp:TemplateField HeaderText="User ID">
<ItemTemplate>
<asp:Label ID="Label3" Text='<%#Eval("userid") %>' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="User Login">
<ItemTemplate>
<asp:Label ID="Label4" Text='<%#Eval("Userlogin") %>' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Pack Amount">
<ItemTemplate>
<asp:Label ID="Password" Text='<%#Eval("Userpassword") %>' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="For">
<ItemTemplate>
<asp:Label ID="First name" Text='<%#Eval("Firstname") %>' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Validity">
<ItemTemplate>
<asp:Label ID="Last name" Text='<%#Eval("Lastname") %> Months' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Now come to the problem, i set the AllowPaging="True" and page size to 3 records/page but when click on paging links it displays the following error :
The GridView 'myGridView' fired event PageIndexChanging which wasn't handled.
Description:
An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I have been stuck on this for a while and I can't seem to get it to work despite looking for answers in books and all over the web, so I hope perhaps you all can help me figure this out...
Here's what I'm trying to do....
I have some information in a simple product database displaying in a gridview table. One of the columns is a row of checkboxes indicating whether the item has been discontinued or not. When the row gets updated, it needs to update the checkbox value in the database.
1. It needs to be disabled until the row is getting edited.
2. Send the string value of 0 or 1 to the database when the row is updated.
Here's the code for the sql datasource and the gridview part in question...
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:sqlDataMaster %>"
ProviderName="<%$ ConnectionStrings:sqlDataMaster.ProviderName %>"
SelectCommand="SELECT ID, ProductName, ListPrice, Discontinued FROM Products"
UpdateCommand="UPDATE Products SET ProductName=@ProductName, ListPrice=@ListPrice, Discontinued=@Discontinued WHERE ID=@ID"
DeleteCommand="DELETE FROM Products WHERE ID=@ID">
<UpdateParameters>
<asp:Parameter Name="ID" Type="Int32" />
<asp:Parameter Name="ProductName" Type="String" />
<asp:Parameter Name="ListPrice" Type="Double" />
<asp:Parameter Name="Discontinued" Type="Boolean" />
</UpdateParameters>
<DeleteParameters>
<asp:Parameter Name="ID" Type="Int32" />
<asp:Parameter Name="ProductName" Type="String" />
<asp:Parameter Name="ListPrice" Type="Double" />
<asp:Parameter Name="Discontinued" Type="Boolean" />
</DeleteParameters>
</asp:SqlDataSource>
<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
AutoGenerateColumns="False" AllowSorting="True"
DataSourceID="SqlDataSource1" CellPadding="3"
GridLines="Vertical" BackColor="White" BorderColor="#999999"
BorderStyle="None" BorderWidth="1px"
DataKeyNames = "ID">
<Columns>
<asp:CommandField ShowSelectButton="True" ShowEditButton="true" ShowDeleteButton="true" />
<asp:BoundField DataField="ID" HeaderText="Product ID" SortExpression="ID" ReadOnly="true" />
<asp:BoundField DataField="ProductName" HeaderText="Product Name"
SortExpression="ProductName" >
<ItemStyle HorizontalAlign="Left" />
</asp:BoundField>
<asp:BoundField DataField="ListPrice" DataFormatString="{0:c}"
HeaderText="Unit Price" SortExpression="ListPrice" />
<asp:TemplateField HeaderText="Discontinued" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:CheckBox id="Discontinued" runat="server"
Checked='<%#Convert.ToBoolean(Eval("Discontinued")) %>' />
</ItemTemplate>
<ItemStyle HorizontalAlign="Center"></ItemStyle>
</asp:TemplateField>
</Columns>
<FooterStyle BackColor="#CCCCCC" ForeColor="Black" />
<PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" />
<SelectedRowStyle BackColor="#008A8C" Font-Bold="True" ForeColor="White" />
<HeaderStyle BackColor="#000084" Font-Bold="True" ForeColor="White" />

I am trying to hook up custom pagination with an ObjectDataSource to my GridView. However, this thing renders no data, but does render the column headers. The debugger clearly indicates a populated DataTable being returned.

I have used ASD.NET code using SQL Database for Transaction operation successfully. By changing the Database Code to interface with MYSQL an Error occurs. If I remove the Transaction Code from within the the application, it works OK by displaying the MYSQL data (Read Only) in the layout of the application. I am using Mysql Essential-4.1.22-win32 and MYSQL Connector ODBC-3.51.2. My objective is to EDIT the MYSQL Data.

Why does a very simple script which inserts 26,000 records into a mysql database (myisam, no transactions) take 13 seconds in the php implementation, and then 35-50 seconds using mono+mysql connector? I thought asp.net was faster than php? Could the problem be the mono mysql connector is "platform independent", so the performance just stinks? or does asp.net suffer more overhead than php when it comes to executing each query? Aren't there any native linux binaries for mysql connector for mono that may be faster?

Now i am developing web application, i wanted to be like a CMS but not with all the bells and whistles of a fully blown CMS system. To explain the idea, it is a classifieds ads site were users can log on and add their own ads or browse other users' ads. What i want to be able to do is to have full control on the application without having to write any line of code. I mean, after the application is launched, i want to be able to add / delete ad categories, change dynamic content on the site (like banners, polls and so on).
I managed to create a control panel for myself where i can edit and manage the ad categories (after all it's a data repeater bound to a database and rendering to an ul list containing the categories). My question now is: i am using Master / child pages design, I have some content that's on the Master page and other on the child pages (by content i mean those plugins that are frequently found on websites like polls, news tickers, stocks...etc). Using the Master / Chile paradigm: how can i control the visibilty of those controls through my control panel?
add labels for those controls and control their content from the backend database together with a boolen indicating their visibility. But the problem is that: how can i determine which page is serving this content currently. Like for example, a news ticker on the addad.aspx child page but not on viewads.aspx child page.

But within the Table Tag second issue is it possiple to feed data into a page and then run a mysql query like i was doing in php.

Let's say I have a gridview with some columns like, title, name, funding agency. Here's an example of what I want to do:
I want to display all the records in the gridview to start. There would be a dropdownlist that lets the user select whether to search by title, name, funding agency and a text box that lets them type in what they want to search for (and a button to start the search). After searching, the gridview would only display the records that matched the criteria.i already know how to connect datasets to the gridview, but i am using mysql database and writing code in vb.how to accomplish this task
