how to bind arraylist elements to gridview using asp.net

Dec 21, 2010
Introduction:

Here I will explain how to bind arraylist elements to gridview using asp.net.

Description:

In my application we bind some of elements to arraylist items after that we need to bind that elements to gridview upto that I don’t have idea to bind arraylist to gridview. I searched many websites and I found good materials regarding how to bind arraylist items to our gridview.

In arrays we have different types

1.       1) Single dimensional array
2.       2) Two dimensional array
3.       3) Multi dimensional array

Now I will explain each one how to bind all these arrays into gridview

Single Dimensional array

Design aspx page like this 


<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Grdview with Arraylist</title>
<style type="text/css">
.Gridview
{
font-family:Verdana;
font-size:10pt;
font-weight:normal;
color:black;
width:200px;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:GridView ID="gvarray" runat="server" CssClass="Gridview" AutoGenerateColumns="false" HeaderStyle-BackColor="#7779AF" HeaderStyle-ForeColor="White" Caption="Single-Dimensional Array">
<Columns>
<asp:BoundField DataField="Name" HeaderText="Name"/>
</Columns>
</asp:GridView>
</div>
</form>
</body>
</html>
In codebehind write the following code


protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
BindGridview();
}
}
private void BindGridview()
{
string[] arrlist = { "aspdotnet", "Suresh", "Dasari","India","AndhraPradesh","Guntur" };
DataTable dt = new DataTable();
dt.Columns.Add("Name");
for (int i = 0; i < arrlist.Count();i++)
{
dt.Rows.Add();
dt.Rows[i]["Name"] = arrlist[i].ToString();
}
gvarray.DataSource = dt;
gvarray.DataBind();
}
Demo

Two Dimensional arrays

Use same aspx page but change gridview code in your aspx page 


<div>
<asp:GridView ID="gvarray" runat="server" CssClass="Gridview" AutoGenerateColumns="false" HeaderStyle-BackColor="#7779AF" HeaderStyle-ForeColor="White" Caption="Two-Dimensional Array">
<Columns>
<asp:BoundField DataField="Name" HeaderText="Name"/>
<asp:BoundField DataField ="Education" HeaderText="Education" />
</Columns>
</asp:GridView>
</div>
After that write the following code in code behind for two dimensional arrays 


protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
BindGridview();
}
}
private void BindGridview()
{
string[,] arrlist = {
                    {"Suresh", "B.Tech"},
                    {"Nagaraju","MCA"},
                    {"Mahesh","MBA"},
                    {"Mahendra","B.Tech"}
                    };
DataTable dt = new DataTable();
dt.Columns.Add("Name");
dt.Columns.Add("Education");

for (int i = 0; i < arrlist.GetLength(0);i++)
{
dt.Rows.Add();
dt.Rows[i]["Name"] = arrlist[i,0].ToString();
dt.Rows[i]["Education"] = arrlist[i,1].ToString();
}
gvarray.DataSource = dt;
gvarray.DataBind();
}
Demo

Now we will discuss about multi dimensional arrays code for multi demensional arrays same like our two dimensional arrays.

Multi-Dimensional arrays

Use same aspx page but change gridview code in your aspx page 


<div>
<asp:GridView ID="gvarray" runat="server" CssClass="Gridview" AutoGenerateColumns="false" HeaderStyle-BackColor="#7779AF" HeaderStyle-ForeColor="White" Caption="Multi-Dimensional Array">
<Columns>
<asp:BoundField DataField="Name" HeaderText="Name"/>
<asp:BoundField DataField ="Education" HeaderText="Education" />
<asp:BoundField DataField="Age" HeaderText="Age" />
<asp:BoundField DataField="Designation" HeaderText="Designation" />
</Columns>
</asp:GridView>
</div>
After that write the following code in code behind for Multi dimensional arrays 

protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
BindGridview();
}
}
private void BindGridview()
{
string[,] arrlist = {
                    {"Suresh", "B.Tech","24","Software Engineer"},
                    {"Nagaraju","MCA","27","Team Leader"},
                    {"Mahesh","MBA","22","Marketing Executive"},
                    {"Mahendra","B.Tech","21","Trainer"}
                    };
DataTable dt = new DataTable();
dt.Columns.Add("Name");
dt.Columns.Add("Education");
dt.Columns.Add("Age");
dt.Columns.Add("Designation");

for (int i = 0; i < arrlist.GetLength(0);i++)
{
dt.Rows.Add();
dt.Rows[i]["Name"] = arrlist[i,0].ToString();
dt.Rows[i]["Education"] = arrlist[i,1].ToString();
dt.Rows[i]["Age"] = arrlist[i, 2].ToString();
dt.Rows[i]["Designation"] = arrlist[i, 3].ToString();
}
gvarray.DataSource = dt;
gvarray.DataBind();
}
Demo

Very nice article. However your example of a 3 dimentional array is actually only a 2 dimentional array with extra columns.

-1 dimensional array has one column and takes 1 parameter (ie. string[3])
-2 dimension has more then 1 column and takes 2 parameters (ie. string[3,2])
-3 dimension is like a cube. It contains more then one 2 dimension array. However the 2 dimensional arrays inside the cube have to be the same size throughout. It takes three parameters to do this (ie. string[3,2,4])

Check out this link that will show you visual

Nice job, but i want to create a gridview from an array
with arrays. The first array in the array contains the columnames

single dimensional always give error because it will not concede more than 6 data item. to solve this use this procedure:
private void BindGridView()
{
string[] array = { "pakistan", "china", "indonasia", "malaysia", "germany", "dutch", "italt" };
DataTable dt= new DataTable();
dt.Columns.Add("names");
int count=0;
for (int i = 0; i <= array.Count(); i++)
{
dt.Rows.Add();
dt.Rows[i]["names"] = array[i].ToString();
count++;
if (count == array.Count())
{
break;
}
}

gvarray.DataSource = dt;
gvarray.DataBind();
}
