Repeater

-

 Repeater is a data control.

 It is used to display the controls in repeated manner.

Repeater Control Event Handling [Using Eval()]

In order to attain Event Handling we have to create two events.

1. Event of repeater's itself-

OnItemCommand

2. Event of the control inside the repeater-

CommandName

Note:- we don't use onClick Event for controls in repeater.

------------------------------------

Format-

<asp:Repeater ID="Repeater1" runat="server" OnItemCommand="repeat_click">

<ItemTemplate>


<img src='/file_name<%# Eval("column_name") %>' height="100px" width="100px"/> 

<asp:Label ID="Label1" runat="server" Text='<%# Eval("column_name")%>'></asp:Label>

<asp:Button ID="Btn1" runat="server"  Text="Submit" CommandName="submit_click" />


</ItemTemplate>

</asp:Repeater> 

Coding-

//Creating the Event of repeater in .aspx.cs- 

protected void repeat_click(object source, RepeaterCommandEventArgs e)

{

if(e.CommandName=="submit_click")

{

//finding the control

Button b1 = (Button)e.Item.FindControl("Btn1");

//logic about the button here

Response.Write(Button1.Text);

}


}

Parameter Query

-
If we pass the value with (, ' " ! $) symbols in the control that will not be accepted through normal query. Parameter Query is used to accept the value with special symbols in the control like textbox. Parameter Query use a user defined variable with an @ sign.  In Parameter Query control is written in a different syntax. Column name and variable name can not be the same. Without column_name we can not perform Parameter query. Syntax- Insert- string s= "insert into Table_name (Column_name) values (@variable_name)"; cm = new SqlCommand(s,cn); cm.Parameters.AddWithValue("variable_name", control_name); cm.ExecuteNonQuery(); Update- string q = "update Proc_table set name=@name1 where email = @email1"; cm = new SqlCommand(q, cn); cm.Parameters.AddWithValue("name1", TextBox1.Text); cm.Parameters.AddWithValue("email1", TextBox2.Text); cm.ExecuteNonQuery();
