How to get parent control id from child popup box in jquery with .net ?

Today I have got a case study in which I need to open a pop-up box on click of link from my asp.net web page and then I need to close that pop-up window after submit button get clicked.
   Isn't it very simple case and I am sure most of developers definetly gone through this situation once.If you google then you will see lots of ways available to do this.I did the same and found some of options in which only few worked for me which I want to share with you guys.
Ok, now lets dive into it.
My web page is using master page and for opening pop-up , I have used IFrame in <div> tag and for open this pop-up on button click I have used jquery code.

Pop-up window code on web page is :

1.<div id="divPopup"  class="popupReqCall">
2.        <div class="Close" style="display: none;">
3.            <img src="images/close.png" border="none" onclick="Close()"  alt="X" />
4.        </div>      
5.      <iframe id="ITestPopup" frameborder="0" scrolling="no" align="top"></iframe>
6.</div>

Here , line 1 is used as container of form control page (which contains textboxs and button) and line 2-4 is used as container of close button image with CSS and close() function which will fire on image click.Last but not the least, line 5 is used for holding user control page which will be add dynamically on click of link.

For getting id of parent <div> id and image control , I need to write jquery code which would be -
var frame = $('[id$=ITestPopup]', window.parent.document);
var imgClose = $('.Close', window.parent.document);

That's it !!
These are the key lines which we can use in any function which would be called on submit button click.
Noticiable part in this line is that first parameter is used as id of control,CSS class or any thing which represent that control and second parameter is defined that id of control is on called page i.e, parent page.
Hope this will help !! Happy Coding..

How to fix header in repeater control in asp.net ?

Some time developers need a feature of fixed header to show thousands of data on the web pages.So, this tutorial will show how to fix header of control.Here, control can be repeater , gridview or any control which is using for showing data in asp.net.

For showing data , I am using repeater control and code will be like -

<asp:repeater id="Repeater1" runat="server">
  <HeaderTemplate>
     <table id="table12" width="505" style="table-layout: fixed; border:solid 1px black">
       <thead>
           <tr id="thead" style="width: 505px; background-color:#BEBEBE">
                <td>Name</td>
                <td>Mobile No</td>
                <td>Address</td>
            </tr>
        </thead>
  </HeaderTemplate>
  <ItemTemplate>
            <tr>
               <td>
                      <%#DataBinder.Eval(Container.DataItem, "Name")%>
               </td>
               <td>
                     <%#DataBinder.Eval(Container.DataItem,"MobileNo")%>
               </td>
                <td>
                      <%#DataBinder.Eval(Container.DataItem,"Address")%>
                </td>
            </tr>
   </ItemTemplate>
   <FooterTemplate>
      </table>
   </FooterTemplate>
 </asp:repeater>

In repeater control, I have design a HTML table which will be used for containing bind data.Thing which should be noticed here is style which is defined in <table> with id 'table12'.
In style , 'table-layout' property is fixed due to which the horizontal layout only depends on the table's width and the width of the columns, not the contents of the cells.
Now,give boundry to repeater control , so that,fixed header effect can be noticed.
<div style="overflow: scroll; height: 100px; width: 505px">
      <asp:repeater id="Repeater1" runat="server">
        ...............
      </asp:repeater>
</div>

Create another <div> tag which will hold header column names dynamically.
<div id="tableHeader">
</div>
Now finally the magic part, a javascript code -

function fixHeader()
{
   //get the id of table used in repeater control
   var t = document.getElementById("table12");
   var thead = t.getElementsByTagName("thead")[0];
   var t1 = t.cloneNode(false);
   t1.appendChild(thead);
   tableHeader.appendChild(t1)
}
       //call fixHeader() function on page load
        window.onload = fixHeader

put this code in <script> tag in <head> section of web page.
Output will be something like -

I hope that this tutorial will help you somewhere.

How to flip text or image vertical on mouse over in CSS ?

This tutorial is about flip any text or image verticaly by using CSS class.
In .aspx page , write a <div> container in <body> tag which contains text which need to be flip.
Like -

<div>
    <!-- container would have your background image -->
    <h3> Hello There!</h3>
    <p> Here is some text</p>
</div>

after that , create CSS class which will do the magic of flip

<style type="text/css">

.flip-vertical :hover
{
    -moz-transform: scaleY(-1);
    -webkit-transform: scaleY(-1);
    -o-transform: scaleY(-1);
    transform: scaleY(-1);
    -ms-filter: flipv;
    filter: flipv;
 }

</style>

and use this class in <div> tag , so that text written in it will start flip on mouse over.
The complete code would be like :

How to get and set textbox value in jquery with asp.net

In this tutorial , I will explain how to get and set textbox value in jquery.
Firstly , add a latest reference of jquery library file in your page which you can either download from
http://www.jquery.com
or you can add CDN link like :
//ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js.

Now, define one textbox control on page like :

<asp:TextBox ID="txtName" runat="server"></asp:TextBox>

For getting value of textbox in jquery, simply write :
$('#<textbox ID>').val();

like in above example :
$('#txtName').val();

For setting value of textbox control :
$('#txtName').val('Test');

That's it. Isn't it so simple !!! :-)

But one point I want to mention here that if you are using page in Master page, then it's possible that you will not be able to get and set control value like this because after rendering page, control id gets change like something 'ctl00$MainContent$Pending$txtName'.
So, by using $('#txtName') you will not get or set any thing.
    For getting id of textbox used in master page, you have to change code like :
$('[id$=txtName]').val();
here '$=' is basically used as one of attributes filter and syntax is :
[attribute$=value]
it matches elements that have the specified attribute and it ends with a certain value.

How to create database driven role base menu in asp.net with c#

For my new task, I wanted to create role based menu where menu options will be change as per user role.
        The only condition was the first menu option 'Home' will remain same for all users with different page url. Like if user is admin then 'Home' link contain default admin page but if user is normal user then on the same 'Home' link default page will be show as per user need.

I have google and found many links but didn't get any role base menu link. So finally, with little trick and twist, I have created this menu which I wanted to share with you guys.

Firstly, create a method GetRolebaseMenuDetail(int UserID) to read data from database to dataset.For reading data , I have used stored procedure which return menu data.Pass User ID as parameter in stored procedure.

public DataSet GetRolebaseMenuDetail(int UserID)
        {

            DataSet dsTemp = new DataSet();
            DataRelation relation;
            using (SqlConnection conn = new SqlConnection(connectionString))
            {
                using (SqlCommand comm = new SqlCommand())
                {
                    comm.Connection = conn;
                    comm.CommandText = "spMenuDetailsRoleWise";
                    comm.CommandType = CommandType.StoredProcedure;
                    comm.Parameters.AddWithValue("@UserID", UserID.ToString());
                    SqlDataAdapter da = new SqlDataAdapter(comm);
                    da.Fill(dsTemp);
                    da.Dispose();
                }
            }

            dsTemp.DataSetName = "Menus";
            dsTemp.Tables[0].TableName = "Menu";
            dsTemp.Tables[1].TableName = "RoleDetail";
 
   //set parent and child relationship between menu data
            relation = new DataRelation("ParentChild", dsTemp.Tables["Menu"].Columns["MenuID"], dsTemp.Tables["Menu"].Columns["ParentID"], false);
            relation.Nested = true;

            dsTemp.Relations.Add(relation);
            return dsTemp;
        }

After reading data in dataset , now bind Menu control

public void PopulateRolebaseMenu(int UserID,string HomePageURL)
        {
            DataSet dsMenu = GetRolebaseMenuDetail(UserID);
       
            foreach (DataRow masterRow in dsMenu.Tables["Menu"].Rows)
            {
                MenuItem masterItem = null;
                if (Convert.ToInt32(masterRow["ParentID"]) == 0)
                {
                    masterItem = new MenuItem((string)masterRow["Menu_Name"]);
                    masterItem.ToolTip = masterRow["Tooltip"].ToString();
                    if (masterRow["Menu_Name"].ToString() == "Home")
                    {
                        masterItem.NavigateUrl = HomePageURL;
                    }
                    else
                        masterItem.NavigateUrl = masterRow["URL"].ToString();
                    Menu1.Items.Add(masterItem);
                }

                foreach (DataRow childRow in masterRow.GetChildRows("ParentChild"))
                {
                    MenuItem childItem = new MenuItem((string)childRow["Menu_Name"]);
                    childItem.NavigateUrl = childRow["URL"].ToString();
                    childItem.ToolTip = childRow["Tooltip"].ToString();
                    masterItem.ChildItems.Add(childItem);
                }
            }      
        }


Here , first parameter is the User's Id who just login and second is the default page url which should be open on default 'Home' option , as per User role.
Happy Coding !!!! :-)
