I have a textBox with AutoCompelte Extender, Autocomplete Text is from Database.
I had Written a Stored Proc for Autocomplete List(In Which I m binding Two Columns from Two Different Tables with crossJoin).
My problem is :
When I select a Value from Autocomplete TextBox and CLick on Search Button, MY Select Query Behind the Button is not Fetching any Value.
MY Code is:
SqlConnection Con = new SqlConnection("DataSource=Localhost;User ID = sa; Password =xxxxx;Initial Catalog =sample;");
SqlCommand cmd = new SqlCommand("Select * from tblCategoryDetails where CategoryName LIKE '"+ TextSearch.Text"' ", con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
da.Fill(dt);
GridView3.DataSource = dt;
GridView3.DataBind();
Can anyone help me on this
That isn't a stored procedure but just a sql command.
SqlCommand cmd = new SqlCommand("Select * from tblCategoryDetails where CategoryName LIKE '"+ TextSearch.Text"' ", Con);
Try to put wild card % within the SqlCommand
("Select * from tblCategoryDetails where CategoryName LIKE '%"+ TextSearch.Text + "%' ", Con);
[System.Web.Script.Services.ScriptMethod()]
[System.Web.Services.WebMethod]
public static List<string> CategoryName(string prefixText, string contextKey)
{
//Your Stored Procedure HERE then,
Your Sql Query where Condition should be
where Category Like '%' + @Category + '%'
//Return to get List you search
List<string> Category= new List<string>();
for (int i = 0; i < dt.Rows.Count; i++)
{
Category.Add(dt.Rows[i]["Category"].ToString());
}
return Category;
}
In your Markup Code : Inside AutoCompleteExtender : ServiceMEthod should be same as your webmethod class
<asp:AutoCompleteExtender ID="AutoComp" runat="server" TargetControlID="txtsrch"
MinimumPrefixLength="3" EnableCaching="true" CompletionSetCount="1" CompletionInterval="1"
OnClientItemSelected="ClientItemSelected" ServiceMethod="CategoryName" CompletionListCssClass="completionListElement"
CompletionListHighlightedItemCssClass="AutoComplete_ListItemHilite" CompletionListItemCssClass="listItem" OnClientPopulated="ClientPopulated" UseContextKey="true"
OnClientShowing="clientShowingsrch">
</asp:AutoCompleteExtender>
