I have this code on ASPX
<div class="col-md-8 col-sm-12 text-poster-box">
<p tabindex="1">
<asp:Label ID="LabelResultName" CssClass="h3" runat="server">Name: <%# Eval("Name") %> </asp:Label>
</p>
<p tabindex="2">
<asp:Label ID="LabelResultPrice" CssClass="h3" runat="server">Price: <%# Eval("Price") %>$ </asp:Label>
</p>
<p tabindex="3">
<asp:Label ID="LabelResultSalePrice" runat="server" CssClass="h3" Visible='<%#Eval("SalePrice").ToString() != "" ? true : false %>'>New Price: <%#Eval("SalePrice")%>$</asp:Label>
</p>
<p tabindex="4">
<asp:Label ID="LabelSize" CssClass="h3" runat="server">Size: <%# Eval("Size") %></asp:Label>
</p>
<p tabindex="5">
<asp:Button ID="ButtonRemove" runat="server" CssClass="btn btn-primary-c wishlist" Text="Remove" OnClick="ButtonRemove_Click" />
</p>
<p tabindex="6">
<asp:Label ID="lblListNumber" Text='<%# Container.ItemIndex%>' runat="server" Visible="true" /></td>
</p>
</div>
and i would like to use the number given by Content.ItemIndex in Code Behind so I could remove from List<T> of objects like this:
MyList.RemoveAt("value received from Content.ItemIndex")
I have no clue if this is even possible?
I would use onitemcommand for the repeater.
For example:
<asp:Repeater id="rptYourPages" runat="server" onitemcommand="rpt_ItemCommand">
Then add CommandArgument with an Eval for the ID of the record to the button.
CommandArgument='<%# Eval("ProductID") %>'
Your Button code would look like this:
<asp:Button ID="ButtonRemove" runat="server" CssClass="btn btn-primary-c wishlist" Text="Remove" CommandArgument='<%# Eval("ProductID") %>' />
You don't need the OnClick.
In the code behind file:
protected void rpt_ItemCommand(object source, RepeaterCommandEventArgs e)
{
string sProductID = e.CommandArgument.ToString();
// Write your logic here...
}
Hope this helps.

I'm using a datalist control to show product details before adding to cart. But here add to cart button is not working. How can I resolve this problem?

Here is the code of c# against OnItemCommand handler
protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName == "addtocart")
{
ClientScript.RegisterStartupScript(this.GetType(), "randomtext", "not_login()", true);
}
}
Add
onclick = "DataList1_ItemCommand"
in your HTML button code
because onclick Event Main Tips. The "onclick" event occurs when the user clicks on an element. It runs a specified line of code when you click an HTML object that has the “onclick” attribute. The event can be triggered by "object.onclick" or "object.addEventListener".
I'm working on product cart page. Below is the code I'm working with. In the list view I'm getting all the products images as buttons. I want to update the carousel when any of the image in the list view clicked.
But When I click the image the page refreshes, I tried using update panel but since the button are dynamic can't able to find a proper way to handle it.

You can register button for async postback inside an updatepanel by add a new OnPreRender event on the button:
protected void btnReloadQty_PreRender(object sender, EventArgs e)
{
ScriptManager scriptMan = ScriptManager.GetCurrent(this.Page);
scriptMan.RegisterAsyncPostBackControl((LinkButton)sender);
}

Here i need the image will retrive and set to image3 id.Please help me to solve this issue.
WHere is image3; it's not in your snippet. Please include that, but if it's in the grid, then you do:
var img3 = (Image)GridView1.Rows[index].Cells[X].FindControl("Image3");
img3.ImageUrl = "XYZ";
Direct references only work when on the page outside of a container. If inside a container, you have to use FindControl (such as detailsview.findcontrol) or if a repeatable list, you have to use FindControl from the row (or in the case of the grid, the cell).
Get row index like this:
GridViewRow gvr = (GridViewRow)(((HyperLink)e.CommandSource).NamingContainer);
int index= gvr.RowIndex;
// to get image url
string url = ((Image)gvr.FindControl("Image3")).ImageUrl;
Image3.ImageUrl= url;
I've a got ListBox called lbxUpcommingEvents. When the index is changed the event handler is fired to check for duplicate records. If duplicates are not found, a panel called pnlAction inside a formview is turned on by the way of display style. If dups are found another panel pnlActionCancel is turned on and the oter is tuned off. Basically a toogle effect.
I've tried the visible property, viewstate property, but it does not work and I can't figure it out so once again, I seek wizdom from the collective. Here is my code.
protected void lbxUpcommingEvents_OnSelectedIndexChanged(object sender, EventArgs e)
{
pnlEventsSignUp.Visible = true;
string _selectedItemValue = lbxUpcommingEvents.SelectedValue.ToString();
int _eventid = Convert.ToInt32(_selectedItemValue);
Guid _memberId = Guid.Empty;
_memberId = new Guid(Session["myId"].ToString());
// Check for existing signup
EventsMemberSignup _createSingup = new EventsMemberSignup();
dsEventsSingupTableAdapters.MemberEventsTableAdapter da = new dsEventsSingupTableAdapters.MemberEventsTableAdapter();
dsEventsSingup.MemberEventsDataTable dt = da.GetDataForDupCheck(_memberId, _eventid);
if (dt.Rows.Count == 1)
{
Panel pnlAction = (Panel)(fvEventSignUp.FindControl("pnlAction"));
//pnlAction.Visible = false;
pnlAction.Style.Add("display","none");
Panel pnlActionCancel = (Panel)(fvEventSignUp.FindControl("pnlActionCancel"));
//pnlActionCancel.Visible = true;
pnlActionCancel.Style.Remove("display");
}
else
{
Panel pnlActionCancel = (Panel)(fvEventSignUp.FindControl("pnlActionCancel"));
//pnlActionCancel.Visible = false;
pnlActionCancel.Style.Add("display", "none");
Panel pnlAction = (Panel)(fvEventSignUp.FindControl("pnlAction"));
//pnlAction.Visible = true;
pnlAction.Style.Remove("display");
}

I've set the ViewStateMode to "Disabled". I'm just hoping it won't back fire somewhere else.
Your existing code might work if you drop an update panel and place your controls inside it.
Alternatively you can create a property in your page like
private bool myRowCount;
protected bool HasRowsMyData
{
get { return myRowCount; }
set { myRowCount=value; }
}
Then inside your selectedIndex change event
if (dt.Rows.Count == 1)
{
HasRowsMyData=true;
//DataBind your controls here
YourUpdatePanel.Update();
}
Inside your aspx on panels you can set each panel's visible property like this so whenever page is updated they will turn on/off depeding upon the result
Visible='<%#HasRowsMyData%>'
Visible='<%#!HasRowsMyData%>'
If you like to do it client side I advise jQuery's toggle function
jQuey:toggle()
Here is my code :
<div class="Cat-list unselectable" style="font-weight:bold;">
<div class="right-bar-nav-item">
<asp:HyperLink runat="server" ID="lnkHome" NavigateUrl="~/Default.aspx">Home</asp:HyperLink>
</div>
<asp:Repeater runat="server" ID="menu" DataSourceID="SiteMapDataSource1">
<ItemTemplate>
<div class="right-bar-nav-item">
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Eval("Url") %>' ToolTip='<%# Eval("description") %>'><%# Eval("Title") %></asp:HyperLink>
</div>
</ItemTemplate>
</asp:Repeater>
</div>
<div style="clear:both;"></div>
<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" ShowStartingNode="false" />
I'd like to give class ".selected" to Current Node. example: if its Default.aspx then it should change from <div class="right-bar-nav-item"> to this <div class="right-bar-nav-item selected">
$(function(){
var url = window.location.pathname,
urlRegExp = new RegExp(url.replace(/\/$/,'') + "$");
// now grab every link from the navigation
$('.menu a').each(function(){
// and test its normalized href against the url pathname regexp
if(urlRegExp.test(this.href.replace(/\/$/,''))){
$(this).addClass('selected');
}
});
});
Here is how you can do this in javascript.
