View 11 RepliesHere is what am trying to accomplish...I want to have a DropDownList that is populated by a field from a table. Then once a user selects one of the enteries, he/she then enters a value for that selection in a textbox, then clicks enter or add....now upon doing this, I want to have a GridView that tabulates all the entries the user adds, and keep a total of all entries as the bottomline in the GridView. I can't seem to wrap my head around how to get it done.Does anyone know how I can get this done, or are there examples out there that my searches have missed cause I haven't really seen any examples I could look at. I would think this should be a common solution that is used all over
View 4 RepliesI have a master table that will hold the information for publications for my company. Not all of the publications can veiwed by all users. What I am trying to figure out is how can I load all of the publications that the user is allowed to see into one grid view table. For example: If Mary logs in she will only be able to see Accounts publications; if Sally logs in she can see General and Legal publications and if John logs in he can see IT, Legal and General publications.
I figured out how to do it with separate gridview tables on a page based on the roles. I would make a gridview viewable if the user was in that role. But I would really like to put all of this in one gridview if that is possible.

View 9 RepliesI 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:

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: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.

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.

View 1 RepliesI am having a gridview with alternative color i have used AlternatingRowsDefaultCellStyle. however, if my grid is not fullyfilled, ie the grid view page size is 20 and i have only 10 records in that page then the alternate row color will not apply for blank rows. My question is, How can I fill the blank rows with alternate color as well.
Hope there is some solution without adding empty rows at the end of the datasoure which will create problems while sorting the grids.
I have 2 GridViews, the InnerGridView is nested inside a TemplateField of my OuterGridView.
Each GridView has an ObjectDataSource (ODS). I want the InnerGridView to display data that is unique
to the GroupName that is listed in the OuterGridView. I have been Googling this for weeks, seeing various based around RowDataBound and the ODS Selecting event.
I don't think RowDataBound is the answer, because the Selecting event for the InnerGridView ODS
has already been called when RowDataBound is called for the OuterGridView.
So, I need to send a parameter to the ODS for the InnerGridView:
[code]...
Note: This method is assigned to the Selecting event of the InnerGridView ODS.
How do I access the GroupName from the OuterGridView... while I am processing the InnerGridView.
Here is an example of something that does not work:
OuterGridView.SelectedRow.FindControl( "GroupName" ).ToString();
I have heard that one can find any control from inside the Selecting event by searching a certain hierarchy.
But I don't know how to access that hierarchy using the "e" or "sender" parms.
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?

I have some template columns that have multiple textboxes in them.
There is one textbox for the Date portion of a datetime field and another textbox for the Time portion of the datetime field.
How do I populate those textboxes after the user clicks on the "Edit" button?
My assumption was I could get the data from the label that was displaying the datetime field data, break it down into Date and Time, and then access the textboxes.text property to fill those.
I can get the data from the label control, but when trying to fill the two textboxes with the data, I get Object Reference Not Set... errors.
Im assuming maybe those textboxes are not setup yet during the RowEditing Event?
