View 1 Repliesi got a problem to update my database which i bounded to datagrid. The problem is, i want to update my database only by clicking one update button at the bottom.. when the user click it, all the fields will be updated to database.
View 3 RepliesI have a gridview in a page, and some Texboxes along with a button(for issuing a command) in the same page. The TextBoxs were inputted values and the values could be assigned to the selected row of the gridview, some fields are the same values along the rows, and the values are inputted in the TextBoxes for using several times without change.
Well, I need to know: how can I assign the values of the TextBoxes to the selected row of the gridview. in another words, how can I access the cell members of the gridview when it is in edit mode? (Q1)
If the row is not selected, I have no way to know which row should be assigned values, since there is no such things like "current row".
So, if the selecting button(or link) of the gridview is not selected, the button along with the TextBoxes should keep disabled, until a row's "Edit" button is clicked. (Q2: How can I find if the Edit button is clicked? I guess I can use the property "mode" of the gridview to indicate the situation. )
And the last question is (Q3), how can I ensure the values are updated to the database? Maybe I dont need to do more things than just click the uppdate button of the row of the gridview.
I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.

we have a AutoGenerateColumns-enabled WmxDataGrid in which we are able to update table rows in a DataBase connected with a SqlDataSource.
Each time we clear a field an empty string is written to the database where we want to write DBNull values.
At the moment we generate the update string via UPDATE... SET.. and the SQL Server function NULLIF(value, '').
Works proper but when I want to add the values to e.NewValues in BeginUpdate event I'm not able to read the values from the auto generated text boxes. How do I do that? Is there an easier way to automatically convert empty strings to NULL values?
I'm coding my first VB web application, which allows a user to input an order number and pull up invoice and shipping data linkd to that order number.
I have the first bit down and working, where the existing data in the database is displayed in the GridViews. One of the GridViews is set up to allow data editing, and I have syntax set to make the row editable, but I'm struggling with getting the "Update" link/functionality to work. I want to assign the values in each cell to an object (ie. 'dgInvNumber' for Invoice Number), but everything I've tried (been doing a ton of Google searching for help, but no luck yet) keeps giving me an "Object reference not set
to an instance of an object" error when I click the Update link for the row of data being edited.
At this point, I don't know what syntax to use to get the edited values out of the GridView row and assigned to objects for each cell (I have a total of 10 cells that can be edited in a row).
For background info, the GridView is set up with Bound Fields. I'm using Visual Studio 2005. Alot of places I've looked talk about TextBox controls and using FindControl. Also seen some places talk about DataBoundLiteral Controls. I tried the latter with no luck (still getting error). For TextBox controls, I don't understand how to use that part, since it mentions referencing the TextBox controls declared in the EditItemTemplates of the TemplateField column fields in the GridView control. But I didn't set up anything in the EditItemTemplates (that I know of).
I am using this reference to make some application .. In this article we can only save with varchar data types
So how to use some other data types like datetime, money, int..or how to use parameters to convert data.

I'm using code to convert items in a Datagrid row from UPPERCASE to Title Case. It works good, but the problem is if it comes across a hyperlink field, it will put in a blank value. Not sure why its doing this, but here is the code below. Wondered if any one has came across this problem and managed to solve it?
The code:
aspx page:
<asp:GridView ID="SectionsGridLevel1" AutoGenerateColumns="False" onrowdatabound="SectionsGridLevel1_RowDataBound" emptydatatext="No data available." runat="server">
<Columns>
<asp:hyperlinkfield headertext="Section - click to view sub-sections" datatextfield="SectName" datanavigateurlformatstring="BrowseSections2.aspx?type=sect&list=1&level=2§ion={0}" datanavigateurlfields="SectID" />
<asp:hyperlinkfield headertext="View" Text="View All" datanavigateurlformatstring="BrowseSections2.aspx?list=1§ion={0}" datanavigateurlfields="SectID" />

I am using the following code to update the data in my datagrid.
But when I click update the value is updated in the database but it still shows old value in datagrid.
If I refresh the page after that then datagrid shows the updated value.
Code On Update Command:
protected void MySQLDataGrid2_UpdateCommand(object source, DataGridCommandEventArgs e)
{
string newData;
TextBox aTextBox;
aTextBox = (TextBox)(e.Item.Cells[0].Controls[0]);
newData = aTextBox.Text;
decimal comm = Convert.ToDecimal(newData);
string UpdateHiveCommission = "Update tbl_HiveCommission set Commission = '" + Convert.ToDecimal(newData) + "'";
MySqlConnection objMyCon3 = new MySqlConnection(strProvider);
objMyCon3.Open();
MySqlCommand cmd3 = new MySqlCommand(UpdateHiveCommission, objMyCon3);
cmd3.ExecuteNonQuery();
objMyCon3.Close();
MySQLDataGrid2.EditItemIndex = -1;
MySQLDataGrid2.DataBind();
}
