Hi,

ViewState is limited to postbacks for single page only.

You can not access value of viewstate of one page from another.

Use session instead.

You might start by reading a basic book, so you have some sort of clue about what you're doing.

You have two options:

1 - you can do a cross page postback, where page 1 sets up page 2 to see it's viewstate. This is an ugly hack
2 - you can take your two pages, turn them into controls, show them on the same page, and then they will share viewstate b/c they are the same page.

they all create those elements using css and basic html controls. They dont use the original input control.

Say for example, you can set css background:url('path') using javascript to a div when mouse hovers on it. This will create the the effect that you are talking about.

You can create a dropdown using ul,li and a few divs and css. You need to trap the events.

To do them, you must have knowledge about basic html constructs and javascript.

For time being check Yahoo UI controls. They have already built such controls. Thumbs Up | :thumbsup:

Applying Search Criteria to GridView using Object data Source with store procedure

atul_007in12-Aug-09 20:11

Following Should be the Code of Object data source in source file
< asp:ObjectDataSource ID="ObjectDataSource1" runat="server" OldValuesParameterFormatString="original_{0}"
SelectMethod="DisplayDoctorsbyId" TypeName="DoctorsBLL"
DeleteMethod="DeletemdnationdoctorsById" >

<selectparameters>

<asp:parameter name="id" defaultvalue="-1" type="Int32">
<asp:parameter name="sLastName" type="string" defaultvalue=" ">

There is store procedure which is called in select method of Object data source it is for displaying data on the basis of search u do

ALTER PROC [dbo].[Proc_DisplaymdnationdoctorsById]
@id int,
@SLastNAME VARCHAR(50)

This Should come under cs file on button click, add text box though to enter the text you want to search

if (tbPhysicians.Text.Trim() != "")
{

//ObjectDataSource1.FilterExpression="LastName LIKE '%" + tbPhysicians.Text + "%'";
ObjectDataSource1.SelectParameters["id"].DefaultValue = "-1";
ObjectDataSource1.SelectParameters["slastname"].DefaultValue = DoctorName;

}
else
{
ObjectDataSource1.SelectParameters["id"].DefaultValue = "-1";
ObjectDataSource1.SelectParameters["slastname"].DefaultValue = " ";

}
ObjectDataSource1.DataBind();
