Asp - Updating GridView With DataSet Source
Mar 23, 2011
I am working on a page to let a user import an excel file into our database. I want to allow the user to manipulate certain fields before committing the information so I loaded a DataSet from the Excel file and bound that to a GridView. For some reason on rowUpdate my NewValues collection is empty. Here is my GridView:
<cc1:WWGridView ID="gvImportDisplay" runat="server" CssClass="grid-view" AllowSorting="false" ShowHeader="true"
AutoGenerateColumns="true"
AutoGenerateEditButton="true"
OnRowEditing="gvImportDisplay_RowEditing"
OnRowCancelingEdit="gvImportDisplay_RowCancelingEdit"
OnRowUpdating="gvImportDisplay_RowUpdating"
>
<EmptyDataTemplate>0 results found. </EmptyDataTemplate>
</cc1:WWGridView>..............................

When I add a column to my database my .edmx is not updated when I use the 'UPDATE MODEL FROM DATABASE' context menu. No matter what I do the .edmx file is never reflective of the added column. I tried to close the project and reopen it, no luck. I closed the vwd 2010 and restarted it, no luck. I finally decided to delete and rebuild the .edmx file from scratch. This is when I finally had success of viewing the added colum in the .edmx display, even though the added colum showed all along in the Database Explorer? Could there possibly be a hotfix or something that I am missing either for SQL 2008 R2 or VS 2010 VWD?
Also my Movie.cs file which carries the 'partial call Movie' as outlined in the tutorial and the namespace Movies.Models, is not produceing the [Required(Errormsg:...)] against the Title field. When I look thru Movies.Designer.cs, I have identical namespace of Movies.Model and the class Partial Movie enties present. I am not at all sure why there is no recognition between the two modules resulting in a valid client validation check?

I have an asp.net application using visual studio express 2008. On one of my pages I created a dataset from one of my database tables. I am able to delete rows and add rows to the new dataset table. I then have a button and on the click event I use the commandbuilder to update the database table. The database table updates with new rows but the deleted rows are not carried out and I can not figure out why desite spending several hours on google to resolve this issue?
Here is some of my code:
Protected Sub Button_updateDatabase_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button_updateDatabase.Click
Try
'I have created a session variable for my data adapter
Dim commandbuilder As SqlCommandBuilder = New SqlCommandBuilder(Session("Adapter"))
Session("Adapter").UpdateCommand = commandbuilder.GetUpdateCommand
Session("Adapter").DeleteCommand = commandbuilder.GetDeleteCommand
'I created a session variable for my dataset
'This update command updates new rows to my database table but not deleted rows
Session("Adapter").Update(Session("CalendarDataset"), "Name")
Catch ex As Exception
Response.Write(ex.Message)
End Try
End Sub

I have a dataset where I would like to upper all string fileds and when done check each field for a value. The other way i thought to do it is to do an upper of each string when I do the conditional check. I would like to know what is quicker upper of the values in the dataset or upper in the conditional statement? Knowing the dataset will contain a max of 10.000 rows and there are multiple conditional statements in the complete process.

I'm hoping someone can point me in the right direction. I will be as detailed as I can in explaining the issue;I have a dataset I have instantiated in a class file (vb.net), and fill the data succesfully. That data is then dumped into an excel file. What I need to do is to go through all the data in the dataset, and directly update the database, changing a "status" column from "pending" to "processing" based on the store number. As I am new to datasets (relatively speaking, of course), I am not quite certain how to accomplish this task. Below is the code I have so far:

If anyone could provide sample code to use, or could provide a quick bit of code I could just copy and paste in and test,

I have a simple .aspx page. I am using VS 2008. I have a microsoft chart control on the page. In the page_load event, I would like to to populate the chart control. I wrote the following code. I can see the data in the dataset. But for some reason, the data is not seen in the chart control.
Code:
protected void Page_Load(object sender, EventArgs e)

string Sql = "select count " + '|'+'|' + "unit as Tenor, value from qrm.advancecurve order by days asc";
Database db = DatabaseFactory.CreateDatabase("ConnectionString_OracleQRM");

As of now I have successfully stored the questions with varchar(MAX) datatype but when I try to get it in the dataset i get the following error:

I am doing this in a ASP.NET web application.

In my project I work with Entity Framework (LINQ to ENTITY). I only have ADO.NET Entity Data Model and a DAL (Data Access Layer). I also get the data due a WCFClientService. I have a gridview that needed to be exported in Excel.
FlexCel is a tool for generating Excel files based on a template. The only thing I see in demo's is that they work with DataSets.
Is there a way to convert the data in my gridview to a virtual DataSet?
I've written the following method to get the data:

I'm new to this community and got newbie question, briefly in data access in asp.net what is the difference between accessing dataset using typed Dataset and using data sources controls like SQL data source control ...? As I noticed that using data source controls is much easier, but it allows only one data access method i.e. only one query... am I right with that....

I have a relatively complex dataset (numerous tables, some with multiple records) generated from reading in an XML file. I need to connect said dataset fields to an ASP form. At the moment I'm assigning them manually, like so in the pageload:
txt_first_init.Text = formData.ds.Tables["phrmHdrKey"].Rows[0]["first_init"].ToString();
txt_last_name.Text = formData.ds.Tables["phrmHdrKey"].Rows[0]["last_name"].ToString();
ddl_pregnancy_flag.SelectedValue = formData.ds.Tables["pPhrm"].Rows[0]["pregnancy_flag"].ToString();
And conversely when it's time to submit.
formData.ds.Tables["phrmHdrKey"].Rows[0]["first_init"] = txt_first_init.Text;
formData.ds.Tables["phrmHdrKey"].Rows[0]["last_name"] = txt_last_name.Text;
formData.ds.Tables["pPhrm"].Rows[0]["pregnancy_flag"] = ddl_pregnancy_flag.SelectedValue.ToString();
I did some looking into binding the textboxes (and dropdownlists, and checkboxes, and and and...) directly, but it seemed to be too many formats to use.
So this works fine, but as the number of fields increases, those load and unload lists are going to get unwieldy.

I have a parent gridview which has a child gridview in the itemsTemplate. Both are binded to different SqlDataSources. I can successfully update and delete rows in the child gridview. After updating in the child gridview, some related data in the parent gridview are not updated automatically. So i have placed ParentGridview.Databind() in the rowupdated event of child gridview. But it doesnt look working.
How can i accomplish this?

I have a GridView with 5 fields. Only two of the fields are edittable (the others are READONLY).
I have an UpdateCommand as follows
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:NHLPOOL %>"
SelectCommand="SELECT [PlayerID], [Firstname], [lastname], [Goals], [Assists], [Goals]+[Assists] as Points, [AsOfDate] FROM [PlayerStats], [Player] where [PlayerStats].[PlayerID] =[Player].[ID] ORDER BY Points DESC"
UpdateCommand="UPDATE PlayerStats SET Goals =@GOALS, Assists =@ASSISTS, AsofDate=GETDATE() WHERE PLAYERID = @PLAYERID">
</asp:SqlDataSource>
The issue is I want the PLAYERID GV column to be READONLY but I get a runtime error when updating if the PLAYERID is READONLY.
I get the error "
Must declare the scalar variable "@PLAYERID"."

If the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template. Since the gridview is empty it won't bind not allowing rendering of the <footer template> I guess I should create a empty dataset if the gridview is empty. How do I check for this and can this be done in GridviewRowEventArgs

I have a GridView that is populated via a dataset that contain 1 table. I have enabled paging on my GridView.
In my Updating event, I handle the new values and call a store proc to update my database with the new values for the selected row. In order to minimize the call to the DB, instead of getting back a new dataset with the updated values, I simply update the row of the dataset that I have in session with the new values and then I bind back my gridview.
The problem that I have is since I have let's say 5 pages of 10 row... If I update a row on the first page as soon as I click update, the gridview will show the new values. However, if I select page 3 for example, click on update and update the values, once the update is done, the gridview will still be displayed with the old values.

I have a set of dataset with different column retrieved from DB. I need to present the datasets in one GridView (or other ListView etc...) without specifying the column_header. It should present automaticly since the GridView is bind to the DataSet.
In additional, I want this GridView to handle multiple rows edit and update the dataset, idealy, show data in textboxs in initially.How could I set the GridView to edit_model without hardcode column_header and textboxs in 'itemtemplate' or filed.
How could I achieve the bulk edit and update, so that I can assign 'mydataview1.table' to the dataset.

I have a Gridview with these parameters:
<asp:GridView runat="server" ID="ItemGrid" CssClass="Grid"
AutoGenerateColumns="false"
AutoGenerateDeleteButton="true" OnRowDeleting="RowDeleting"
AutoGenerateEditButton="true" onRowEditing="RowEdit"
OnRowCancelingEdit="CancelRowEdit" onRowUpdating="RowUpdating"
DataKeyNames="Item_ID">
<Columns>
<asp:BoundField HeaderText="Item" DataField="Item"/>
<asp:BoundField HeaderText="Family" DataField="Family"/>
<asp:BoundField HeaderText="Structure" DataField="Structure"/>
<asp:BoundField HeaderText="Updated" ReadOnly="true" DataFormatString="{0:d}" DataField="Updated"/>
</Columns>
</asp:GridView>
On updating it calls:
protected void RowUpdating(object sender, GridViewUpdateEventArgs e){
int Item_ID = (int)this.ItemGrid.DataKeys[e.RowIndex][0];[code]...
It generates the Update/Edit/Delete buttons, my Delete function is working exactly how I want and the 'Edit' button generates editable TextBoxes as it should.
My problem is in the updating part, the strings Item, Family, Structure are getting the old values, not the new values I put in the generated text boxes.If I hard code in values they are updated to the database and the DateTime.Now is always updating correctly in the database so the update query is working.
I've been looking at this/reading forums testing things for a couple days now. I'm sure I'm just missing something simple that I have overlooked.
Edit:It has been answered but for those who were curious this is my dataBind();
protected void dataBind()
{
ItemTableAdapter taItem = new ItemTableAdapter();
this.ItemGrid.DataSource = taItem.GetActive();
this.ItemGrid.DataBind();
}
