this problem came the reason for Response.write is add to the c# code also not properly..so, i write the code infront of loop..

below code working properly.

Accessing a DIV Tag with C#

Response.Write("

"); // left:100px; top:100px; width:100px; height:100px; background-color:#ffffff; overflow:auto; scrollbar-face-color : #000000; scrollbar-highlight-color : #000000; scrollbar-3dlight-color : #000000; scrollbar-shadow-color : #000000; scrollbar-darkshadow-color : #000000; scrollbar-track-color : #000000; scrollbar-arrow-color : #000000;>");

for (int i = 0; i <>

{

mydata = InsCarr[i].InsCarrierName; // +"

";

if (ReturnTextbox != null && ReturnTextbox.Trim().Length > 0)

{

//Write to default page, with selection options.

if (MyDiv == null || MyDiv.Trim().Length == 0)

{

Response.Write("

"onmouseout=\"this.style.cursor='pointer';\"" +

"onclick=\"SetTextbox('" +

ReturnTextbox.Trim() + "','" +

mydata + "', '');\">" +

"");

}

else

{

Response.Write("

"onmouseout=\"this.style.cursor='pointer';\"" +

"onclick=\"SetTextbox('" +

ReturnTextbox.Trim() + "','" +

mydata + "', '" +

MyDiv + "');\">" +

"" + mydata + "" +

"

");

}

}

else

{

Response.Write("

" +

mydata + "

");

}

}

Response.Write("

");

}

else

{

return;

}
