VS 2005 / Getting Data From A Row On A GridView?
Aug 14, 2013
I'm creating a website in Visual Studio 2005 with VB.NET which contains a GridView. The GridView is being populated by an SqlDataSource and has Edit and Delete buttons automatically generated.
I have converted some of the columns to ItemTemplates and replaced the TextBox in the EditItemTemplate with a DropDownList.When I click Edit, it changes to say Update and I am trying to perform some validation at this point.
The validation I want to perform is to check all the other rows in the GridView to make sure that the selection chosen in the DropDownList hasn't been selected on another row.
For example,
Row 1 DropDownList = Sick
Row 2 DropDownList = Holiday
Click Edit on Row 2 and change the DropDownList to be Sick and then click Update. I want a message to appear saying "Sick has already been selected" and then cancelling the Update before it happens but leaving the row in Edit mode.
can't seem to find a way to find how to get the value of the DropDownList in Row 1 when I'm editing Row 2.

I just upgraded one of my solutions from VS 2005 to 2008, and it completed successfully. The only thing that changed in the solution was that I went from .NET 2 to 3.5 framework.
Now when I debug and select a page where a GridView displays a table of 4580 rows the time to display it goes from 5 seconds to 5 minutes. Everything else in the project behaves as normal. Why would performance degrade on one GridView when going to VS 2008?
It's also noteworthy that changing the GridView parameters to AllowPaging="True" PageSize="25" will return performance to under a second response, as one might expect.

Is it possible to bind multiple data fields in a tooltip like below:
Code:
Text='<%# Bind("qty_day10") %>' ToolTip='<%# Bind("plant_id" & "product_code") %>'
They work individually but cannot seem to bind both.

I need to programatically fill a GridView. I am looping through a text file that has one string field only and I need to populate the GridView with this data.
I guess I need to add a new row before I can add value .. or? Not sure how to do that.
Code:
Do
myLine = objReader.ReadLine()
If Not myLine Is Nothing Then
GridView1.Rows(i).Cells(0).Text = myLine ?????
End If
i = i + 1
Loop Until myLine Is Nothing

Is there a way where I can set the GridView to always show the total page even when there are not enough records to fill the page? Example, my page size is 12 and if my binding results in 8 rows I want the GridView to be displayed with 12 rows (4 blank rows).

On my desktop the application when showing the gridview does not wrap cells. Now when I publish the application to the (internal) web server it wraps some of the cells. I have set the wrap attribute = false but does not seem to work. Running IE8.
Code:
<RowStyle Wrap="False" Font-Size="10px" />
<AlternatingRowStyle BackColor="#FFFFC0" Wrap="False" Font-Size="10px" />

I have a gridview where I display (from left to right) plant id, product no and month/year and there after a column with qty for every day on the month.
The gridview is located inside a panel that has a horizontal scrollable property set that lets user scroll from left to the right. This works fine.
Now, they are asking if it is possible somehow to freeze plant id and product no? Currently when they scroll past day 10 then plant id and product no is not longer visible and making it hard to see what line you are on.

I have gridview and i am binding data from database. i have a doubt in cell click event.
I have following column in my grid : stock name, price, quantity
by default when data binding the quantity field should be as label. when i click on the cell of quandity row that label should be shown as textbox. so that user can modify the quantity.
[Note : i don't want to use the edit template of having edit button]. i need this has to be done with cell click event. also when i submit the submit button i want to loop through the changed row text box value and that has to be sent to back end.

I have to update a gridview inside an updatepanel in a button click.The thing is i'm having gridview in contentpage.I have placed scriptmanager in masterpage.when i clicked on the button to trigger the updatepanel,no update is happening in gridview.Moreover,after placing updatepanel control in contentpage,i saw a redcurvedline (which is an error basically) below the updatepanel control's text which is showing an error as "Element 'updatepanel' is not known element.This can occur if there is a compilation error in the website" in .aspx page's source view.I have attached the screen shot here of that page here for your reference.
But it's working in ordinary web page.

I can't seem to check the checked value of a dynamic checkbox within a gridview. I've tried dozens of ways to test the checkbox's checked value, but it still returns false, when it should return true. If I change the checked value to true in the ASPX web page, then it will return true, even when it should return false. Any ideas? I've tried many different ways of checking the checkbox value including the one below.

Code:
<asp:GridView ID="GridView" runat="server" AutoGenerateColumns="False" DataKeyNames="NewClientID">
<Columns>
<asp:BoundField DataField="NewClientID" InsertVisible="false" />

I have a gridview which is bound to a dataset. I have placed several template fields in the grid with the following type of setup
HTML Code:
<asp:TemplateField>
<HeaderTemplate>
<asp:Label ID="Label1" runat="server" Text="File"></asp:Label>
<asp:ImageButton AlternateText="ASC" ID="imgASC" Width="10" Height="10"
ImageUrl="~/Modules/Interface/ASC.gif"
CommandArgument="eFolder ASC" runat="server" OnCommand="ImageButton_Command" />
<asp:ImageButton AlternateText="DESC" ID="imgDESC" Width="10" Height="10"
ImageUrl="~/Modules/Interface/DESC.gif"
CommandArgument="eFile DESC" runat="server" OnCommand="ImageButton_Command" />
</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("eFileName") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
on the code page I have mapped the OnCommand event to the following code
Code:
Protected Sub ImageButton_Command(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.CommandEventArgs)
Try
Dim img As ImageButton = CType(sender, ImageButton)
img.BorderStyle = BorderStyle.Ridge
SortOrder = e.CommandArgument
BindData()
Catch exc As Exception
ProcessModuleLoadException(Me, exc)
End Try
End Sub
My problem is that by clicking on the image button in the gridview header, the OnCommand event is not being fired. I have tried this with both OnClick and OnCommand and neither fires. I can't see what I am doing wrong if anything.

I'm a new developer here, working in VB. Have a question that is stumping me as well as some others.
I have a gridview control built. I am not using an <sqldatasource> tag, so I can't use it's autoGenerateSelect/Update/Delete functionality. I have built a template field that has an "edit" link button in it, and by clicking it will fire the grdName_SelectedIndexChanged event of the gridview.
Now, it's in this event where I'm having trouble. I have it coded so that when this event fires, it will build a textbox and button control. Code:
Protected Sub grdResults2_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles grdResults2.SelectedIndexChanged
Dim row As GridViewRow = grdResults2.SelectedRow
Dim cell As TableCell = row.Cells(6)
Dim txtSeq As New TextBox
Dim btnUpdate As New Button
'build the textbox in the Search_Seq cell
txtSeq.ID = "txtSeq"
txtSeq.Width = Unit.Pixel(20)
txtSeq.Text = row.Cells(6).Text
cell.Controls.Add(txtSeq)
'build the "update" button in the Search_Seq cell
btnUpdate.ID = "btnUpdate"
btnUpdate.Text = "Update"
cell.Controls.Add(btnUpdate)
End Sub
So the textbox and button populate perfectly. I can run it in the browser and it works fine.
How do I go about setting up the event for this button now? Because it's being manually built here in the gridview event, there is no button for me to "double_click" on in the design view to auto-build this event. There are some properties that need to be set on this button to link it up to a new event....and that's where I'm lost.
Hopefully I don't leave any additional information out.
