asp.net Can a GridView have two DataSources? - asp.net

Question

Afternoon All,
I have a gridview that i am using to display a list of 'Actions' from a database.
I have a dropdown list that is connected to this gridview, this enables a user to filter the data via the 'Action Status' in the dropdown list ('Assigned', 'Inprogress' & 'Completed'). This works perfectly fine....
What i am trying to do is have another filter option available for the user, they would like to also filter by user name. I have the datasource and the dropdown list set up for this but i can only have one datasource connected to my gridview?
Does anyone have a suggestionon how to enable the users to also filter by username as well as 'action status'?
Here is my code if you need to take a peek....
<asp:SqlDataSource ID="dsActions" runat="server"
ConnectionString="<%$ ConnectionStrings:SMCConnectionString %>"
SelectCommand="Populate_grdAllActions_Filter"
SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:ControlParameter ControlID="ddFilterStatus" Name="ActionStatusID"
PropertyName="SelectedValue" Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
<asp:SqlDataSource ID="dsActionsByUser" runat="server"
ConnectionString="<%$ ConnectionStrings:SMCConnectionString %>"
SelectCommand="Populate_grdAllActions_Filter_By_User"
SelectCommandType="StoredProcedure">
<SelectParameters>
<asp:ControlParameter ControlID="ddFilterUsers" Name="UserID"
PropertyName="SelectedValue" Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
<asp:SqlDataSource ID="dsFilterList" runat="server"
ConnectionString="<%$ ConnectionStrings:SMCConnectionString %>"
SelectCommand="SELECT * FROM [ActionStatus]"></asp:SqlDataSource>
<asp:SqlDataSource ID="dsFilterUsers" runat="server"
ConnectionString="<%$ ConnectionStrings:SMCConnectionString %>"
SelectCommand="SELECT * FROM [UserSimpleList]"></asp:SqlDataSource>
<table style="width: 400px">
<tr>
<td colspan="2" style="height: 25px"><b>Filter Options:</b></td>
</tr>
<tr>
<td style="width: 158px">
Select Action Status:</td>
<td>
<asp:DropDownList ID="ddFilterStatus" runat="server"
DataTextField="ActionStatus" DataValueField="ActionStatusID"
AutoPostBack="True" DataSourceID="dsFilterList"></asp:DropDownList>
</td>
</tr>
<tr>
<td style="width: 158px">
Select Actions by User:</td>
<td>
<asp:DropDownList ID="ddFilterUsers" runat="server"
DataTextField="UserFullName" DataValueField="UserID"
AutoPostBack="True" DataSourceID="dsFilterUsers"></asp:DropDownList></td>
</tr>
</table>

</asp:GridView>
Any help is much appriechiated in advance.

Answer 1

You can determine which option the user selected, then set the Datasource in code-behind rather than wired them up in the aspx.
Pseudocode assumes that if the FilterUsers dropdown was selected, then bind to the Action By User data source:
if(IsPostBack){
if(ddlFilterUsers.SelectedValue <> ""){
grdActions.DataSource = dsActionsByUser;
dsFilterUsers.DataBind();
//etc
}
}

Answer 2

In the code behind part, On ddFilterStatus_SelectIndexChanged() Event, Check for appropriate "Action Status" and Select the Data source as follows,
if(ddFilterStatus.SelectedValue == someid1)
{
grdActions.DataSource = appropriate datasource
}
else
{
grdActions.DataSource = appropriate datasource
}
grdActions.DataBind()
Hope this helps...
