I'm trying to replicate the behaviour in the attached series of jpgs. ( was going to be avideo but can't attach it ). If a user just clicks on a grid row then the row should highlight and an indicator should appear to the left of the grid. If the user actually clicks the check box the row is highlighted, has the indicator and the check box is ticked. There should also be a check box in the grid header to select all rows and show them as ticked or to reset all check boxes back to empty if it is itself ticked. The last clicked row should retain the indicator.

I thought i could use a GridClientSelectColumn to do this but it's behaviour is not quite what I want to replicate.

The application whose functionality i'm trying to replicate uses CSS to overwrite the different check box symbols. It has 4 images, 1 with an empty tick box, 1 with an empty tick box and the indicator, 1 with a ticked box and 1 with ticked box and indicator. I tried to do this by using a GridButtonColumn but that doen't put a button into the header row.

I have a sample app where I'm trying various method but again a can't attach it to the post so here's the code for my grid...

Has anyone any ideas how i might achieve this ?

Hi guys,

Question: Do I have to move my objectdatasource settings for code behind to codebehind in this scenario? If I have to how do I do it?
and in what event? I have been dabbling with this for 2 days now.

I have a Radgrid using the batch editing features of this demo:

http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultcs.aspx

But I have added with some cascading comboboxes to apply some pre-filtering for the entire radgrid. I have an objectdatasource connected to it but since I added the cascading comboboxes to my page. Can I still make the updates defined in my objectdatasource in the ASPX page as I had to move my selectmethods for the grid to codebehind?

On page_load I have the following code 

 if (RadComboBox1.SelectedValue != "" && RadComboBox2.SelectedValue != "" && RadComboBox3.SelectedValue != "")
        {
            Literal1.Text = string.Format(MessageTemplate, RadComboBox3.Text, RadComboBox2.Text, RadComboBox1.Text);
            Lower = RadComboBox2.Text;
            Higher = RadComboBox3.Text;
            GetCompared(Lower, Higher);
        }
        else
        {
            ods1.SelectMethod = "GetSensorBulkData";
        }

if the boxes are all selected I call GetCompared function

 protected void GetCompared(string Lower, string Higher)
    {
        NotifyUser("Är " + Lower + " lägre än " + Higher);
        ods1.TypeName = "DAL";
        ods1.SelectParameters.Clear();
        ods1.SelectParameters.Add("Low", TypeCode.String, Lower);
        ods1.SelectParameters.Add("High", TypeCode.String, Higher);
        ods1.SelectMethod = "GetSensorBulkDataCompared";

    }

I can also call the GetCompared from button click 

protected void Button1_Click(object sender, EventArgs e)
    {
        Literal1.Text = string.Empty;

        if (RadComboBox1.SelectedValue != "" && RadComboBox2.SelectedValue != "" && RadComboBox3.SelectedValue != "")
        {
            Literal1.Text = string.Format(MessageTemplate, RadComboBox3.Text, RadComboBox2.Text, RadComboBox1.Text);

            Lower = RadComboBox2.Text;
            Higher = RadComboBox3.Text;

            GetCompared(Lower, Higher);
        }

This pre filtering I have here is to compare different sites data to see if we have any deviations. and then Adjust settings accordingly if we need to make overrides.

I would prefer if I could tell my objectdatasource to use this update from the ASPX page but for some reasone I get the error 

ObjectDataSource 'ods1' could not find a non-generic method 'UpdateSensorBulkSettings' that has parameters: "all my parameters" + original_ID.

btw I added original_id to the updateparameters and trap it in my dataaccess layer as I didnt think I need it.

<asp:ObjectDataSource ID="ods1" TypeName="DAL" OldValuesParameterFormatString="original_{0}" UpdateMethod="UpdateSensorBulkSettings" runat="server">
        <UpdateParameters>
            <asp:Parameter Name="Id" Type="Int32" />
            <asp:Parameter Name="Site1Main1" Type="Double" />
            <asp:Parameter Name="Site1Main2" Type="Double" />
            <asp:Parameter Name="Site1Main3" Type="Double" />
            <asp:Parameter Name="Enabled" Type="Boolean" />
           <asp:Parameter Name="Site2Main1" Type="Double" />
           <asp:Parameter Name="MatchSite1Main1Settings" Type="Boolean" />
           <asp:Parameter Name="Site2Main2" Type="Double" />
           <asp:Parameter Name="MatchSite1Main2Settings" Type="Boolean" />
           <asp:Parameter Name="Site2Main3" Type="Double" />
           <asp:Parameter Name="MatchSite1Main3Settings" Type="Boolean" />

            <asp:Parameter Name="......other parameters...." Type="Double" />
            <asp:Parameter Name="Username" Type="String" />
            <asp:Parameter Name="original_ID" Type="Int32" />
        </UpdateParameters>
    </asp:ObjectDataSource>

Could anyone please help with this I'm staring myself blind and need some advice here.

I have posted some previous questions relating to this but as I got not answers on the previous post and I managed to fix all but this Issue.

RadGrid1.ExportSettings.IgnorePaging = true;

RadGrid1.MasterTableView.AllowPaging = false;

Before running the export function but still behaves the same way.

How could I achieve this?

I have the UI for Xamarin R3 2016 and i get not set to instance of object when I have below code in xaml.  This is a bug since it works when I remove this code below.  How can I go about this issue?

thanks 

Wil
