I want to get data from the database and display it in gridview. The gridview should be editable. Meaning the user can add, edit and delete items/rows in the gridview. Everytime the user adds/updates/deletes an item, the gridview is also updated. However, these changes will only be saved to the database once the Save button is clicked.

View 5 RepliesI have a page where I will insert all the data into the database. The page where I'm having problems is when I select an item from the checkboxlist it only displays one item. The data which is displayed is only the one that was inserted with one selected item from the checkboxlist. The following code is the page I'm using to try to retrieve the data from the database. I am trying to do is when a user selects the first, second, or third, or fourth item. The corresponding data appears in the gridview. In my current code, the record which has one item selected appears. If the user has more than one selected it does not appear. It comes up as empty. Is there a way I can do it?

I would like to display the following information for each "Camera" (in the format below) on my web page in an HTML table. All the data is contained in one table in my database:
For Camera = Canon (e.g.):
Type (Text via asp:Label)
Lens Size (Text via asp:Label)
Storage (Text via asp:Label)
Max. video resolution (Text via asp:Label)
Max. photo resolution (Text via asp:Label)
Weight (Text via asp:Label)
Dimensions (Text via asp:Label)
Sensor (Text via asp:Label)
...where (Text) is the value retrieved from the database for the given Camera. advise on the best way to retrieve this data? The only method I can think of (from my limited experience!) is to have a separate VB function for each value, to run separate SELECT queries for each field, and then to set the (Text via asp:Label)
value accordingly. I am already doing this for datagrid retrieves etc. For example:[Code]....
BUT... I know there must be a better method for the above requirement!

I want to retrieve the value for the id column for each row in a gridview. I dont want this in a gridview rowdatabound function or anyhting, but an external function.
Normally I would do something like:
Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "id"))
in a rowdatabound event. I now want this from another function, something like:
Private Sub GetGridviewIds()
'THIS DOESNT WORK!
Dim ttypeId As Integer = gvTickettypes.Rows(i).DataItem("id")
End Sub
So how can I access the data value in a gridview row?

How to Retrieve image from database into gridview
View 1 RepliesWhen retrieving values from Gridview empty cells, you will get " " instead of a empty string or null.
Someone once change the columne's properties as following, but it doesn't work
ConvertEmptyString > true
HtmlEncode > false
HtmlEncodeFormatString >false
One solution is to check if the cell value is " ". If so, assign it an empty string. But this approach looks awkward.
I know there are a number of posts along this topic, but everything I find seems to not have a final solution or else I'm just not getting what the solution is. I have a simple GridView with a ButtonField and a BoundField. I'm having the same problem most of the other posts seem to have; I can retrieve the BoundField value easy enough in the RowCommand subroutine, but I can't figure out how to get the value of the ButtonField. Here is the code I'm trying to use:
[Code]....
sAddr is being set to the correct address value, but sName is set to an empty string no matter what I try. The GridView HTML all works correctly, including showing the names from my bound data table on the button text. I can use to retrieve the ButtonField text value?
I have a grid view. When I click edit, the OnRowCommand fires and the row goes into edit state. Label becomes a TextBox. I then attempt to alter this value in some way and click update. This again fires the OnRowCommand event. The problem is, when I attempt to capture the new value, it instead just shows the original value.In my grid view I have:
<asp:TemplateField
HeaderText="Start Name">
<ItemTemplate>
<asp:Label
ID="lblStartName"
runat="server"
Text='<%#Bind("StartName")%>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox
ID="txtStartName"
runat="server"
Text='<%#Bind("StartName") %>'></asp:TextBox>
</EditItemTemplate>
</asp:TemplateField>
In my code behinde i have
TextBox
textBox = (TextBox)row.Cells[4].FindControl("txtStartName");
