The method of Repeater event OnItemCommand to obtain the control of the line

This article mainly introduced the Repeater event OnItemCommand obtains the line internal control method, the need friend may refer to the

Record, mainly this sentence:

TextBox txtnum = E.item.findcontrol ("Txtnum") as TextBox;

Repeater is so strong, so flexible. I don't need anything other than repeater.

The code is as follows:

<table>

<asp:repeater id= "rptlist" runat= "Server" onitemcommand= "Rptlist_itemcommand" >

<ItemTemplate>

<tr>

<td><asp:textbox id= "Txtnum" runat= "server" text= ' <% #Eval ("Pronum")%> ' ></asp:TextBox>< /TD>

<td><asp:button id= "btnupdate" runat= "Server" text= "Update" commandname= "Updates" commandargument= ' <% #Eval (" PID ")%> '/></td>

</tr>

</ItemTemplate>

</asp:Repeater>

</table>

The code is as follows:

protected void Rptlist_itemcommand (object source, RepeaterCommandEventArgs e)

{

Switch (e.commandname)

{

Case "Update":

string arg = E.commandargument.tostring ();//Get Parameters

It is useful to find the control of the line that fires the event, and to pass on more of the required parameter values.

TextBox txtnum = E.item.findcontrol ("Txtnum") as TextBox;

Perform business logic below

String jsstr = "<script>alert (' Delete succeeded!" + Txtnum.text + "') </script>";

Page.ClientScript.RegisterClientScriptBlock (this. GetType (), "alert", Jsstr,false);

Break

}

Bind ();

}
