There is only one placeholder control on the aspx page:
<asp:PlaceHolder ID="Placeholder1" runat="server" />
On the code behind, I am setting a variable called test and on Page_Load, changing the variable to something else. How come, when I click the dynamically added LinkButton, the test variable is not maintaining it's state:
[code]....
Consider i have 3 linkbuttons on a page,
<asp:LinkButton ID="LB1" runat="server" CssClass="regular" OnClick="LB1_Click">
Today</asp:LinkButton>
<asp:LinkButton ID="LB2" runat="server" CssClass="regular" OnClick="LB2_Click">
Today</asp:LinkButton>
<asp:LinkButton ID="LB3" runat="server" CssClass="regular" OnClick="LB3_Click">
Today</asp:LinkButton>
I want to highlight a linkbutton on its click with a css and then remove its css when another linkbutton is clicked (ie) i want to show active link button.
How do I check which LinkButton is clicked in the Page_Load of the page. This is to avoid calls to service so that it only executes what is present in its event.

i am using vs2008. 1/ i am placed a datagrid control, a textbox and a server side button are inside the CollapsiblePanelExtender.
2/ The collapsible panel Extender placed inside the updatepanel.
3/ outside of updatepanel i have another button("next page") to redirect to next page.
When the page is loading, i am displaying all the records in datagrid. For an example 100 rocords. if i entered some values in textbox and click the button it fetches searching result based on inputs and displaying it in datagrid (for example searched result 20).
Now, I click the button "next page" it redirect to next page. if the user click the browser back button, i need to keep the datagrid to show only searched result. but Instead of that, it displaying all the records(100 records). how to resolve this?

I have to build a screen that tracks despatched goods on trucks on a certain date. I have created a form (using C# and ASP.NET) where I am displaying the calendar and am allowing the user to select the date he wants to check for the despatched goods.
My question is how to store the date that was clicked by a user in a variable which I want to use it later in an SQL query.
Should I store the date as a session variable? Suppose I want to display the date that the user clicked, how do I display it?
I want to transfer a variable to another page when a button is clicked. I include the html code in label.text.
Source code is as follows:

oid is the variable that I want to transfer.However, It says "http://localhost:61884 OBJ_Browser.aspx?oid=undefined" when I click this button.
how I can transfer the value of oid to another page?
I want to grab a numeric value from the database and thereby use it in a datagrid. This will be connected to a linkbutton which has a hyperlink which will bring up profile information based on the number returned. I'm getting a value back but when I click the link, the querystring sees <% instead of the id number I want to use. So I'm really not sure what I'm missing so here's my code:

I am creating dynamic TextBoxes in a page by clicking a LinkButton.
However, after that, if the page is submitted, I can't find the items created dynamically, thus, can't send the information to the database.
protected void lbAddTag_Click(object sender, EventArgs e)
{
for (int i = 0; i < 3;i++ )
{
CreateTextBox("txtTag-" + i.ToString());
}
}
private void CreateTextBox(string ID)
{
TextBox txt = new TextBox();
txt.ID = ID;
txt.Width = Unit.Pixel(300);
//txt.TextChanged += new EventHandler(OnTextChanged);
txt.AutoPostBack = false;
tagsPanel.Controls.Add(txt);........
in the lbAddTag_Click method I can see the items, and they exist, but if I submit the page and try to insert the values in the database nothing...

I have a series of linkbuttons that are generated dynamically inside a repeater.
I need the background color of the selected linkButton to change and remain a new color when clicked. I thought that the ItemCommand property of the repeater would do the trick, but it doesn't.
Here is the code for the repeater:

I am working on an ASP.NET web application using .net 4.0 and VS2010.
I have a GridView and I am appending a row at the bottom to allow users to input data for "Adding" a new record.
The ONLY way I have found for this to work is to do this in the RowDataBound event of the grid. I can check to see if it is about to process the footer row then I know I am at the bottom and can insert this new row.
The row I am inserting contains a couple of TextBoxes and a LinkButton for the "Add" link.
If I just drop a LinkButton on my form and hook up the click event and I click the link button then the first thing that fires is the Page_Load event then my click event. However what is happening when I click the link button that was dynamically added to the GridView is the Page_Load event fires but the click event never does.
I have read 1000 threads saying to try to create the controls in the preinit() or some other event. In my case I can't. Or else someone would have to explain how to add the row to the bottom of the databound GridView.
Here is my code: (I removed creating the Textboxes because that is not part of the problem.
[Code]....
the structure is like this:
Grivdivew
ItemTemplate
PlaceHolder
/ItemTemplate
/Gridview
And then I try to add some dynamic controls into the placehold control from code behind, I use the RowDataBound Event
Private Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
Dim ph As PlaceHolder = CType(e.Row.Cells(1).FindControl("PlaceHolder"), PlaceHolder)[code]....
The problem is the button CommandName is not functioning. And more strangely, if I add the button manually into the placeholder, like this:
Grivdivew
ItemTemplate
PlaceHolder[code]....
So I have a GridView control with autogenerated column set to true, it also has autogenerated Edit and Delete buttons, sorting and paging, and also I am binding this same gridview to multiple data sources at runtime. All is working well.
Now I am adding a dynamically generated footer row at runtime. This footer row will allow users to add new record regardless which data source it binds to. So it is working as well except there's a small bug I couldn't figure out why. It's when I navigate to the last page of the gridview, if the rows on the last page is less than the page size, for example, I have page size 10 and the rows in last page is 9, then when I click the 'Add' linkbutton, the Add event does not fire, instead, it fill the last page with additional blank rows, that means if the last page has 5 rows, it will fill 5 blank rows below, if it has 9 rows, it will fill 1 blank row below. Then if you click the add again, it will work. If the last page already has 10 rows then, it works just fine.
Below is the code I used to dynamically add footer row:
