0	Question is no clear !!. i think you want search data from database by category wise SELECT * FROM Employees WHERE (Title LIKE '::dept ::') or SELECT * FROM Employees WHERE (Title Like '% dept %') k@rth!k karthikreddy08a50@gmail.com Rock_Monu, if this helps please login to Mark As Answer. \| Alert Moderator

0	SELECT * FROM tablename WHERE Category LIKE '%Dept%' -- To filter all the rows containing department in the category SELECT * FROM tablename WHERE Category LIKE '%Organisation%' -- To filter all the rows containing Organisation in the category SELECT * FROM tablename WHERE Category LIKE '%Division%' -- To filter all the rows containing Division in the category SailajaReddy Rock_Monu, if this helps please login to Mark As Answer. \| Alert Moderator

SELECT * FROM tablename WHERE Category LIKE '%Dept%' -- To filter all the rows containing department in the category

SELECT * FROM tablename WHERE Category LIKE '%Organisation%' -- To filter all the rows containing Organisation in the category

SELECT * FROM tablename WHERE Category LIKE '%Division%' -- To filter all the rows containing Division in the category

0	Hi You need to filter the values according to the selection of values right. If i am right, See this following example. I have done like this, i used to concatenate the query values according to the selection. The values will get filtered and it will be displayed on the gridview. For example: If you have dropdownlist for organisation,department,division,etc., you need to filter the values according to these selection. Design page: <body> <form id="form1" runat="server"> <div> <asp:DropDownList ID="ddlOrganisation" runat="server" onselectedindexchanged="ddlOrganisation_SelectedIndexChanged"> <asp:ListItem>Select</asp:ListItem> <asp:ListItem>Organisation</asp:ListItem> <asp:ListItem>Org</asp:ListItem> </asp:DropDownList> <asp:DropDownList ID="ddlDepartment" runat="server" onselectedindexchanged="ddlDepartment_SelectedIndexChanged"> <asp:ListItem>Select</asp:ListItem> <asp:ListItem>Software</asp:ListItem> <asp:ListItem>Networking</asp:ListItem> </asp:DropDownList> <asp:DropDownList ID="ddlLocation" runat="server" onselectedindexchanged="ddlLocation_SelectedIndexChanged"> <asp:ListItem>Select</asp:ListItem> <asp:ListItem>Chennai</asp:ListItem> <asp:ListItem>Hydrebad</asp:ListItem> </asp:DropDownList> </div> </form> </body> .CS Page: public partial class Default2 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { PopulateValues(); } protected void ddlOrganisation_SelectedIndexChanged(object sender, EventArgs e) { PopulateValues(); } protected void ddlDepartment_SelectedIndexChanged(object sender, EventArgs e) { PopulateValues(); } protected void ddlLocation_SelectedIndexChanged(object sender, EventArgs e) { PopulateValues(); } protected void PopulateValues() { string Query = "Select * from tablename where empresignedstatus ='No'"; if(ddlDepartment.SelectedItem.Text !="Select") Query += "and Department='"+ ddlDepartment.SelectedItem.Value+"'"; if(ddlOrganisation.SelectedItem.Text != "Select") Query += "and Organisation='" + ddlOrganisation.SelectedItem.Value + "'"; if (ddlLocation.SelectedItem.Text != "Select") Query += "and Location='" + ddlLocation.SelectedItem.Value + "'"; //Here write the SQL Execution coding. } } If you have not selected any values from the dropdownlist, Values will not be filtered .. If you have chosen any values on any one of the dropdown the values will be filtered according to the selection Display those values where you need.. Let me know, if you have any queries Thanks & Regards, Santhi .V Rock_Monu, if this helps please login to Mark As Answer. \| Alert Moderator

Hi

You need to filter the values according to the selection of values right.
If i am right, See this following example.
I have done like this, i used to concatenate the query values according to the selection.
The values will get filtered and it will be displayed on the gridview.
For example:
If you have dropdownlist for organisation,department,division,etc., you need to filter the values according to these selection.

Design page:

<body>

    <form id="form1" runat="server">

    <div>

        <asp:DropDownList ID="ddlOrganisation" runat="server" 

            onselectedindexchanged="ddlOrganisation_SelectedIndexChanged">

            <asp:ListItem>Select</asp:ListItem>

            <asp:ListItem>Organisation</asp:ListItem>

            <asp:ListItem>Org</asp:ListItem>

        </asp:DropDownList>

     <asp:DropDownList ID="ddlDepartment" runat="server" 

            onselectedindexchanged="ddlDepartment_SelectedIndexChanged">

         <asp:ListItem>Select</asp:ListItem>

          <asp:ListItem>Software</asp:ListItem>

        <asp:ListItem>Networking</asp:ListItem>

    </asp:DropDownList>

    <asp:DropDownList ID="ddlLocation" runat="server" 

            onselectedindexchanged="ddlLocation_SelectedIndexChanged">

        <asp:ListItem>Select</asp:ListItem>

  <asp:ListItem>Chennai</asp:ListItem>

         <asp:ListItem>Hydrebad</asp:ListItem>

    </asp:DropDownList>

    </div>

   

    </form>

    

</body>

.CS Page:

public partial class Default2 : System.Web.UI.Page

{

    protected void Page_Load(object sender, EventArgs e)

    {

PopulateValues();

    }

    protected void ddlOrganisation_SelectedIndexChanged(object sender, EventArgs e)

    {

        PopulateValues();

    }

    protected void ddlDepartment_SelectedIndexChanged(object sender, EventArgs e)

    {

        PopulateValues();

    }

    protected void ddlLocation_SelectedIndexChanged(object sender, EventArgs e)

    {

        PopulateValues();



    }

    protected void PopulateValues()

    {

        string Query = "Select * from tablename where empresignedstatus ='No'";

        if(ddlDepartment.SelectedItem.Text !="Select")

            Query += "and Department='"+ ddlDepartment.SelectedItem.Value+"'";

            if(ddlOrganisation.SelectedItem.Text != "Select")

                Query += "and Organisation='" + ddlOrganisation.SelectedItem.Value + "'";

            if (ddlLocation.SelectedItem.Text != "Select")

                Query += "and Location='" + ddlLocation.SelectedItem.Value + "'";



        //Here write the SQL Execution coding.



       

    }

}

If you have not selected any values from the dropdownlist, Values will not be filtered ..
If you have chosen any values on any one of the dropdown the values will be filtered according to the selection
Display those values where you need..
Let me know, if you have any queries

Thanks & Regards,
