Fill UniGrid with data from external web service

Hi Lubormir,

An UniGrid in Kentico API inherits from GridView in ASP.NET so look at this article on StackOverflow : How to bind with GridView or this article how to a DataBind of your Dataset on MSDN : GridView.DataBind Method

You can also have an look at the Kentico UniGrid documentation

Good luck and if you have any problems let us know with some code examples.

If this answer helped you, please vote for my answer :-)

I tried myUniGrid.DataBind() and also myUniGrid.ReloadData() and UniGrid is still empty. I placed ASP GridView on same page and it has data.

Hi Lubomir, It seems that you are doing it correctly, maybe it is the problem of when you assign the datasource. An example of an custom UniGrid webpart I build is this :

/// <summary>
/// Loads and setups web part.
/// </summary>
protected override void OnLoad(EventArgs e)
{
    // Load the grid data
    ReloadGrid();

    base.OnLoad(e);
}

/// <summary>
/// Reloads the grid with given page index.
/// </summary>
protected void ReloadGrid()
{
    // Reload data
    if (this.DataSourceControl != null && DataSourceControl.DataSource != null && !binded)
    {
        System.Data.DataSet ds = new System.Data.DataSet();
        ds.Tables.Add(((System.Data.DataView)DataSourceControl.DataSource).ToTable());

        UniGrid.DataSource = ds;
        UniGrid.OrderBy = this.DataSourceControl.OrderBy;
        UniGrid.ReloadData();
    }
}

I use an DataSource webpart on my page to fill the DataSource, but that cannot be the problem. Het is also Advanced UniGrid example on Kentico.

My code is here, looks like yours.

protected override void OnLoad(EventArgs e)
{
    this.GetMyData();
    base.OnLoad(e);
}

private void GetMyData()
{
    try
    {
        this.InnerGrid.DataSource = null;

        if (this.UniGridId > 0)
        {
            MyWs.MyWs proxy = new MyWs.MyWs();
            DataSet dataSet = proxy.GetDataSetForUniGrid(this.UniGridId, this.UserId);

            // This is UniGrid and is empty
            this.InnerGrid.DataSource = dataSet;
            this.InnerGrid.DataBind();
            this.InnerGrid.ReloadData();

            // This ASP GridView and has data
            this.InnerGridAsp.DataSource = dataSet;
            this.InnerGridAsp.DataBind();

            // This show number of records in UniGrid and is > 0 (VERY WEIRD ???)
            this.InnerLabel.Text = "Rows: " + this.InnerGrid.RowsCount.ToString();
        }
        else
        {
            this.InnerGrid.DataSource = null;
            this.InnerGrid.ReloadData();
        }
    }
    catch (Exception ex)
    {
        this.InnerLabel.Text = ex.ToString();
    }
}

@Lubomir there is no need to call the ReloadData() immediately after you call DataBind(). Do you have a column definition setup for your UniGrid? Have you debugged to see if your UniGrid has data in the dataset after it is bound? What other steps have you taken to debug the issue?

Hi Lubomir, try to remove the DataBind() and only call the ReloadData().

If that is not working I will try it later this night on in my application.

@Maarten, thank you.
