I want to avoid postback when my button event fired. Due to postback my List gets empty again. Kindly Help me out with this. What should i do to avoid postback. I am using ASP button.
Here is my button method
id = Convert.ToInt32(Request.QueryString["id"].ToString());
venues.Add(id);
foreach (int item1 in venues)
{
if (!hashset.Add(item1))
{
Response.Write("<script>alert('Duplicate Items');</script>");
break;
}
else
{
foreach (var items in venues)
{
con.Open();
SqlCommand cmd = con.CreateCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "select * from Venues where VenueID = '" + items + "'";
cmd.ExecuteNonQuery();
DataTable dt = new DataTable();
SqlDataAdapter ds = new SqlDataAdapter(cmd);
ds.Fill(dt);
foreach (DataRow dr in dt.Rows)
{
Name = dr["Name"].ToString();
Address = dr["Address"].ToString();
Picture = dr["Picture"].ToString();
Price = dr["Price"].ToString();
}
con.Close();
if (Request.Cookies["aa"] == null)
{
Response.Cookies["aa"].Value = Name.ToString() + "," + Address.ToString() + "," + Picture.ToString() + "," + Price.ToString();
Response.Cookies["aa"].Expires = DateTime.Now.AddDays(1);
}
else
{
Response.Cookies["aa"].Value = Request.Cookies["aa"].Value + "|" + Name.ToString() + "," + Address.ToString() + "," + Picture.ToString() + "," + Price.ToString();
Response.Cookies["aa"].Expires = DateTime.Now.AddDays(1);
}
}
}
}
}
I have this code om my View. And this is work good.
... onclick="location.href = '#Url.Action("Plan", "Care", new {Area = "HomeC"})'"><img src="~/Content/images/dash/Care.PNG"
How Can I do the same code with Html.Raw?
I tried this
grid.Column(columnName: "Name", header: "", format: #<text>#(item.ListStatus == 1 ? Html.Raw("<button class='btn btn-default btn-plan' title='Care' onclick='location.href = " + "'" + Url.Action("Plan", "Care", new {Area = "HomeC"}) + "''>" +
"<img src='/Content/images/dash/Care.PNG' class='img-plan' data-interlocutorid=" + item.UserId + " " + "data-interlocutorname=" + item.Name + " " + ">" +
"</button>") : Html.Raw(""))
</text>),
With image all good, but link doesn't work.
Change the single-quotes around your Url.Action(...) to double-quotes instead.
That is, change this portion:
onclick='location.href = " + "'" + Url.Action("Plan", "Care", new {Area = "HomeC"}) + "''
to this:
onclick='location.href = " + "\"" + Url.Action("Plan", "Care", new {Area = "HomeC"}) + "\"'
This will change the rendered output from:
onclick='location.href = '/Care/Plan?Area=HomeC''
to:
onclick='location.href = "/Care/Plan?Area=HomeC"'
onclick=" + "location.href=" + "'" + Url.Action("Plan", "Care", new {Area = "HomeC"}) + "'" + ">"
This is work good.

//if (ds.Tables[0] != null )
if (ds1.Tables[0].Rows.Count > 0)
{
GridView_Utilization_Search.Visible = true;
GridView_Utilization_Search.DataSource = ds1.Tables[0];
GridView_Utilization_Search.DataBind();

You should be giving absolute paths to your resources
e.g.
in above code, your body background should be something like
<body background= 'http://yourdomain.com/meet.jpg'>
same thing applies to your image tag or you can have inline content disposition
EDIT
Do you see something like this when you view the mail?
Why does this work:
ListItem item = new ListItem();
string value = lstAvailExtPropsToFilter.SelectedItem.Text +" = "+ txtExtPropToFilter.Text;
string text = lstAvailExtPropsToFilter.SelectedItem.Text + " = " + txtExtPropToFilter.Text;
item.Text = text;
item.Value = value;
lstExtPropsToFilter.Items.Add(item);
But not this:
ListItem item = new ListItem();
string value = string.Format("<key>{0}</key><value>{1}</value>", lstAvailExtPropsToFilter.SelectedItem.Text, txtExtPropToFilter.Text);
string text = lstAvailExtPropsToFilter.SelectedItem.Text + " = " + txtExtPropToFilter.Text;
item.Text = text;
item.Value = value;
lstExtPropsToFilter.Items.Add(item);
You would have to escape the string so it works in HTML. Try Server.HTMLEncode.
Server.HTMLEncode("<key>{0}</key><value>{1}</value>")
Then when you need to pull the value you, use Server.HTMLDecode.
