Accessing a StaticItemTemplate control from a MenuItem - asp.net

I've written the following menu:
<asp:Menu ID="NavigationMenu" runat="server" CssClass="menu" EnableViewState="false" IncludeStyleBlock="false" Orientation="Horizontal">
<Items>
<asp:MenuItem NavigateUrl="javascript:SetRoadMap();" Text="Road Map" Value="SetRoadMap"/>
<asp:MenuItem NavigateUrl="javascript:SetHybridMap();" Text="Hybrid Map" Value="SetHybridMap" />
<asp:MenuItem NavigateUrl="javascript:SearchAddress(document.getElementById('addressToSearch').text);" Text="Search Address" Value="searchAddress" />
</Items>
<StaticItemTemplate>
<asp:Label runat="server" Height="20px" Text='<%# Eval("Text") %>' />
<asp:TextBox ID="addressToSearch" runat="server" Height="15px" Width="250px" Visible='<%# ((string)Eval("Value") == "searchAddress") %>' />
</StaticItemTemplate>
</asp:Menu>
The SearchAddress menu item's URL can't seems to find the text box (id 'addressToSearch') attached to it.
Any advice will be welcome.

I've found the answer:
<asp:Menu ID="NavigationMenu" runat="server" CssClass="menu" EnableViewState="false" IncludeStyleBlock="false" Orientation="Horizontal">
<Items>
<asp:MenuItem NavigateUrl="javascript:SetRoadMap();" Text="Road Map" Value="SetRoadMap"/>
<asp:MenuItem NavigateUrl="javascript:SetHybridMap();" Text="Hybrid Map" Value="SetHybridMap" />
<asp:MenuItem NavigateUrl="javascript:SearchAddress(document.getElementById('addressToSearch').text);" Text="Search Address" Value="searchAddress" />
</Items>
<StaticItemTemplate>
<asp:Label runat="server" Height="20px" Text='<%# Eval("Text") %>' />
<asp:TextBox ID="addressToSearch" runat="server" ClientIDMode="Static" Height="15px" Width="250px" Visible='<%# ((string)Eval("Value") == "searchAddress") %>' />
</StaticItemTemplate>
</asp:Menu>
I should have added the ClientIDMode property and looked for Value instead of Text.

I am implementing the functionality that on button click the data saved in the gridview should get exported on the button click, I implemented the functionality from here.

Exporting GridView to Excel is easier using a 3rd party like iTextSharp.
If you want to know how I make it work, you can check this sample code:
http://dotnetfrommanila.blogspot.com/2013/04/convert-gridview-to-excel-in-c.html
I hope it could help you.
I got it done on my own,
actually I forgot to add the code below and EnableEventValidation="false".
The code was:-
public override void VerifyRenderingInServerForm(Control control)
{
/* Verifies that the control is rendered */
}
and it worked.!!

ASP.NET DropDownList in FormView

Been working on an ASP.NET form, and struggling with one particular part. I'm using a SqlDataSource with an Insert function that points to a stored proc, with a few input parameters. I have a FormView set up. I would like for one of the form's input fields to be a DropDownList whose options are populated from a different SqlDataSource. For reference, here is the formview:
<asp:FormView runat="server" id="FormView1" DataSourceID="SqlDataSource1" DefaultMode="Insert">

<asp:parameter DefaultValue="dfsdf" Name="user" Type="String" />
</InsertParameters>
</asp:SqlDataSource>
The data populates in the DDL just fine (from another SqlDataSource). All of the desired options come up. But when submitting the form, I get an error. I removed the DDL and hard-coded a value to that parameter, and it executed fine. I spent the last couple hours scouring the internet for a solution, finding tons, trying them, and not having any luck. I'm a DBA by trade, so .NET is not my forté, but it really doesn't seem like it should be this difficult to get a DDL to work like this.
WOW. After being very frustrated, I decided to start from scratch and give it another go, just to make sure I didn't miss anything. I built everything EXACTLY the same, MINUS all of the table elements... and it worked perfectly. I added the table elements back, stopped working. Removed them again: works.
No idea why, perhaps an .NET-proficient person can explain why, but it definitely solved my problem.

How can i add a event handler to a customized button inside listview?

I have a table tblexpense in my database. I have columns named Taxinreal , Taxinpercent,*Amount* NetAmount.*NetAmount* is computed column which is equal to*(Amount-Taxinreal-Taxinpercent)* Now what i want is at runtime in my aspx page the user must be able to insert amount,tax,taxinpercentage and according to the value supplied by user NetAmount must be calculated(Netamount=Amount-Tax-Taxpercentage) at runtime and inserted into the database.For this purpose i have a differencebutton which should perform the required mathematical operation. The problem i am having is i am using a listview. Now adding a new button is simple but how can i perform required mathematical operation in the click event of difference button so that when the listview is in update mode the user can change values of taxinreal ,taxinpercent and obtain the result at runtime and the result be updated in database ??? I need solution urgently(P.S. I need to use Listview only).
You want to use OnItemCommand of ListView.
Here is a sample.
You need to insert/update to database (using either ADO.Net, entity framework or linq-to-sql) in code behind if you want to perform calculation.

asp.net Menu control is not highlighting the selected item

I am trying to set the backcolor on the asp.net menu's selected item but it has no effect.
<div id="navepanel" style="float:left;">
<asp:Menu ID="Menu1" runat="server">
<StaticSelectedStyle BackColor="#D5D9F7" />
<DynamicSelectedStyle BackColor="#D5D9F7" />
<Items>
<asp:MenuItem Text="New Chapter" Value="New Chapter" NavigateUrl="~/ChapterManagement/CreateNewChapter.aspx"></asp:MenuItem>
<asp:MenuItem Text="Edit Chapter" Value="Edit Chapter" NavigateUrl ="~/ChapterManagement/EditChapter.aspx"></asp:MenuItem>
<asp:MenuItem Text="Select Chapter" Value="Select Chapter" NavigateUrl ="~/ChapterManagement/SelectChapter.aspx"></asp:MenuItem>
<asp:MenuItem Text="Add Topics" Value="Add Topics" NavigateUrl ="~/ChapterManagement/AddTopics.aspx"></asp:MenuItem>
</Items>
</asp:Menu>
I am using Chrome currently for the testing purpose. This menu control is on the master page.
Try this:
<asp:Menu ID="NavigationMenu" runat="server" CssClass="menu" StaticDisplayLevels="1"
Orientation="Horizontal" DataSourceID="SiteMapDataSource1" >
<staticselectedstyle backcolor="LightBlue" />
</asp:Menu>
<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" ShowStartingNode="false" />

Button refuses to work

I have a standard button which should call a method but it just refuses to work and I can't figure out why.
ASP code:
<asp:FileUpload ID="FileUpload1" runat="server" />
<asp:Button
ID="UploadButton" runat="server" onclick="UploadButton_Click" Text="Change Logo" />
Code behind:
protected void UploadButton_Click(object sender, EventArgs e)
{
PasswordLabel.Visible = true;
PasswordLabel.Text = "TEST Before";
Image_Inserting(this);
PasswordLabel.Text = "TEST After";
}
I just added the textbox methods to test it but it doesn't seem to be posting back (even when I remove Image_Inserting call). All other buttons work fine so I don't know why this one won't work.

PasswordLabel .Attributes["value"] = "aaa";
