Please change align="left" to style="text-align:left". Please change align="right" to style="text-align:right". Please change align="center" to style="text-align:center".

Migrating from EF 4 to EF 4.5

If you do have a previous class that uses entity framework in visual studio 2010. Then you need to create the same class using visual studio 2012. When you try to copy and paste into the new class. Then compile it, it will give you an error. In visual studio 2010 Addto<tablename> method and DeleteObject method no longer exist. Please use <tablename>.Add method and <tablename>.Remove method respectively. For insert, user add method and for delete, use remove method.

How to validate an Ajax control combo box has item selected or not?

First, you need to insert beside the combo box a custom validator like this,

<asp:CustomValidator ID="cv" runat="server" ControlToValidate="cmb" Text="*" ForeColor="Red" ValidateEmptyText="true" ClientValidationFunction="CustomValidator" Display="Dynamic" ErrorMessage="combo box is required!" CssClass="validator" ValidationGroup="valGrp"></asp:CustomValidator>

If your combo box default selected value is an empty string then you need to add a function inside a <script type="text/javascript"> like this,

function CustomValidator(s, e) {

if ($find(s.controltovalidate)._textBoxControl.value == "") {

e.IsValid = false;

}

If your combo box default value of “Please select” then you need to add a function inside a <script type="text/javascript”> like this,

function CustomValidator(s, e) {

if ($find(s.controltovalidate)._textBoxControl.value == "Please select") {

e.IsValid = false;

}

How fix the column width in a gridview at insert tooltip in each cell in Asp.net 4?

If you need to set the width of each column in a gridview control, If the column is just to display and no editing needed. You can like this,

<asp:TemplateField HeaderText="column Name" SortExpression="fieldname">

<div style="text-align:center;background-color:#41627E;color:White;font-size:x-small;font-weight:bold;overflow: hidden;white-space: nowrap;width: 50px;" >column Name</div>

</HeaderTemplate>

<asp:Label ID="lblGridColumnName" runat="server" Text='<%# Bind("fieldname") %>' ></asp:Label>

</div>

</ItemTemplate>

</asp:TemplateField>

But if there is a editing to be done, you need to do like this,

<asp:TemplateField HeaderText="column Name" SortExpression="fieldname">

<div style="text-align:center;background-color:#41627E;color:White;font-size:x-small;font-weight:bold;overflow: hidden;white-space: nowrap;width: 40px;" >column name</div>

</HeaderTemplate>

<asp:Label ID="lblGridColumnName" runat="server" Text='<%# Bind("fieldname", "{0:n0}") %>'></asp:Label>

</div>

</ItemTemplate>

<asp:TextBox ID="txtGridColumnName" runat="server" Text='<%# Eval("fieldname", "{0:n0}") %>' Width="50px" CssClass="cssclass" />

</EditItemTemplate>

</asp:TemplateField>

If you need insert a tooltip for each cell inside a gridview, you need to set each column tooltip. You can do like this,

protected void gv_DataBound(object sender, EventArgs e)

{

Label lbl = new Label();

foreach (GridViewRow rv in gv.Rows)

{

lbl = (Label)rv.FindControl("lblGridColumnName ");

rv.Cells[1].ToolTip = lbl == null ? string.Empty : lbl.Text;

}

How to manipulate back button in ASP.NET 4?

After searching a lot of references. I have came to a conclusion that you can only prevent user from accessing the previous page is thru javascript window history. You can not manipulate the forward button but only the back button. There are many ways to do it, if you really want to manipulate both button is to clear cache like this,
Response.Buffer = true;
Response.ExpiresAbsolute = DateTime.Now.AddDays(-1);
Response.Expires = 0;
Response.CacheControl = “no-cache”;

To manipulate the previous page (back button) is thru this way,

<script type="text/javascript" language="javascript">
function DeleteHistory() {
window.history.go('Default.aspx');
}
setTimeout("DeleteHistory()", 1000);
window.onunload = function () { DeleteHistory(); };
</script>
