Following is code for buttonclick in gridview.
Protected Sub lnkChangeStatus_Click(ByVal sender As Object, ByVal e As EventArgs)
Dim gvr As GridViewRow = TryCast(DirectCast(sender, LinkButton).Parent.Parent, GridViewRow)
Dim lngProfileId As Long = Convert.ToInt64(gvwBusinessProfiles.DataKeys(gvr.RowIndex).Value)
End Sub
I want to get commandargument of lnkChangeStatus in its click.
I have a DataTable that contains 3 fields: ACount, BCount and DCount. If ACount < 0 then I need to display 'S' in one of the columns of the GridView. If ACount > 0 then I have to display 'D' in that column(in label).Same thing with BCount and DCount. How can I do this conditional check in the RowDataBound function?
View 2 RepliesI have asked a question similar to this in the past. I was able to resolve it by removing gvRowDataBound completely from the code. This is similar code except I can't remove gvRowDataBound sub.
The issue is that when you click the Edit button of the first row, it allows you to successfully update that row.After the first row, if you click on thr edit button of any other row, enter the value to update, it doesn't update that row.
Instead, the cursor moves down to the next row. I didn't design this and having difficulty figuring out what needs to change.

I am trying to an ImageUrl to an image in a Template Field in GridView but keep getting the error:
Object reference not set to an instance of an object. on this line:
Dim imagePath As String = rowView("image_path")
I've never done this before on a GridView but had it working on a ListView.
Heres my code:
.APSX
<asp:GridView ID="gvImages" DataKeyNames="id" runat="server" AutoGenerateColumns="False" BorderWidth="0px" GridLines="None">
<Columns>
<asp:TemplateField>
<ItemTemplate>

I'm trying to change the backcolor of a .Net GridView when a certain condition is met. This should be fairly straightforward, but the color change isn't happening. Checking the rendered HTML shows absolutely nothing different in the affected rows even though the text change on the link is happening as expected.There is a default theme set for all gridviews and I haven't worked with that in the past. Is that preventing me from dynamically changing the color of a row or am I missing something else? I'm using .Net 3.5 and have the following in my code behind:
Protected Sub gvPrevious_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs) Handles gvPrevious.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then
If currentCorrespondence.IsRetired Then //custom object, returning as expected
Dim link As LinkButton = DirectCast(e.Row.Controls(4).Controls(2), LinkButton)
[code]....
From the above code, when I go into the browser and view source, I would expect to see <tr style="background-color: #CD5C5C;"> for the affected rows. Instead, I see <tr> and <tr class="AlternateRowStyle"> (where appropriate). I see absolutely no effect from the BackColor property change. I have also attempted to use e.Row.CssClass with the same result.
I have a GridView control which I am dynamically binding to a DataTable which is populated by a query built based on a set of selected options.What I am trying to do is simply handle the RowDataBound event in order to format specific rows based on the value of a database field. The code in this event handler works fine. My problem is, calling this event causes the GridView to only display the first record in the DataTable, almost as if the Gridview stops after binding to the DataTable after the first row is bound. I have attempted adding the handler dynamically, but I get the same results.I know for a fact that there is sufficient data being returned (the DataTable fills with all of the records, and the GridView shows all the records fine when not touching the RowDataBound event).
I'm adding the handler immediately after generating the query, filling the DataTable, and binding the GridView: [code]I have also determined that, when handling RowDataBound, the GridView's DATABOUND event never gets fired; it seems to stop binding right after binding the first row.
I'm following this exampleto build an editable GridView control.I have this code in my GridView:
<asp:TemplateField HeaderText="Negócio">
<ItemTemplate>
<asp:Label ID="lblNegocio" runat="server" Text='<%# Eval("Negocio") %>'></asp:Label>

I am using a template field in a GridView. The template field is a dropdown list that is generated dynamically in the RowDataBound event.
How can I add a Javascript validation to each of those dropdown lists when they're created?
I am trying to pass a querystring value via the commandargument of a linkbutton. It doesn't seem to be getting the value and just passing the actual text in the commandargument.
page:
<asp:LinkButton ID="LinkButton1"
runat="server"
CausesValidation="False"
[Code]....
My button gets a commandargument of empty string even though the commandargument gets set. I have verified it gets set to the correct ID in debug mode, but then when I go to access this commandargument later in the repeaters ItemCommand event the commandarguments are empty string. And I have no idea why. I end up getting a sq foreign key exception because it is inserting an ID of 0 from the empty string values. There is no other code regarding the repeaters buttons that would be resetting it.
Repeater:
<asp:Repeater ID="repeaterAddresses" ViewStateMode="Enabled" DataSourceID="sqlFacilityAddresses" runat="server">
<ItemTemplate>
<Select:Address ID="AddressControl" runat="server" />

I have a multilingual company website (Visual Studio / VB / ASP.NET 4.0), and when, on the homepage, you click a flag, the text changes to that language and stays with you the entire session, after I made a class, BasePage.vb. Everything works great, but the URL never changes .... clients.aspx remains clients.aspx although the text DOES switch to Dutch.
It's been recommended by @Aritstos to make it so it looks like clients.aspx?lang=nl as opposed to just clients.aspx in another language.
Currently, my asp homepage hyperlinks that work look like this:
<asp:LinkButton ID="LinkButton7" runat="server"
CommandArgument="nl" OnClick="RequestLanguageChange_Click"
class="flagbutton">

I have a page that has two dropdownlists(one for the locations, and the other for departments), an employee search textbox and a button. On the other page, I have a gridview. Now, what i want to archieve is that when a user types an employee's name in the textbox control, selects a location from the location dropdownlist, and a department from the departments dropdownlist, and click the button(search), the gridview on the other page must show the reqiured information of a SINGLE employee. Only one row must show.
