child grid search? + multi column sorting?

[hosein]

Hi

I have radControls for winforms 2010 Q3

I tried "Custom Filtering" codes in demo and it works fine

But I want to search the child templates (child grids) too.

How can I do that?

thanks

Hello Hosein,

Thank you for your question.

The mechanism for implementing custom filtering for the master and the child templates of RadGridView is the same. All you should do is enable the filtering and custom filtering of the concrete template, add FilterDescriptor to it and subscribe to the CustomFiltering event of RadGridView:

this.radGridView1.Templates[0].EnableFiltering = true;
this.radGridView1.Templates[0].EnableCustomFiltering = true;
this.radGridView1.CustomFiltering += new GridViewCustomFilteringEventHandler(radGridView1_CustomFiltering);

this.radGridView1.Templates[0].FilterDescriptors.Add(new FilterDescriptor());

private void radGridView1_CustomFiltering(object sender, GridViewCustomFilteringEventArgs e)
{
}

I hope it helps.

Hello

Thanks a lot for answer (I was waiting about three days for any help)

I wrote these codes in radGridView1_CustomFiltering(object sender, GridViewCustomFilteringEventArgs e)

if (string.IsNullOrEmpty(txtSearch.Text))
            {
                e.Visible = true;
                for (int i = 0; i < radGridView1.ColumnCount; i++)
                {
                    e.Row.Cells[i].Style.Reset();
                    e.Row.InvalidateRow();
                }
                return;
            }
            e.Visible = false;
            for (int i = 0; i < this.radGridView1.ColumnCount; i++)
            {
                string text = e.Row.Cells[i].Value.ToString();
                if (text.IndexOf(txtSearch.Text, 0, StringComparison.InvariantCultureIgnoreCase) >= 0)
                {
                    e.Visible = true;
                    e.Row.Cells[i].Style.CustomizeFill = true;
                    e.Row.Cells[i].Style.DrawFill = true;
                    e.Row.Cells[i].Style.BackColor = Color.FromArgb(201, 252, 254);
                }
                else
                {
                    e.Row.Cells[i].Style.Reset();
                    e.Row.InvalidateRow();
                }
            }

I also add These two lines to the code:

this.radGridView1.Templates[0].EnableFiltering = true;
this.radGridView1.Templates[0].EnableCustomFiltering = true;

But it does not search the child templates.

How can I change the code to search the child templates too?

Thanks

Hello,

In order to get to the child template, you can itterate over the rows, and inside that loop, itterate over the child rows.

Please see my answer in this forum post regarding getting to the child rows.
Hope that helps
