TableSearchRow - Collection of results

[Andreas Haeusler]

Hello,

 

is there any way to access a collection of the cells/rows that match the search criteria?

I'm trying to implement a combined search/filter - function -- using the SearchProgressChangedEvent to hide all rows that do not match the search criteria.

 

 

Kind regards,

Andreas

Hello Andreas,

Thank you for writing.

Here is a sample code snippet demonstrating how to get the search results in RadGridView:

public Form1()
{
    InitializeComponent();
    this.radGridView1.AllowSearchRow = true;
    this.radGridView1.MasterView.TableSearchRow.InitialSearchResultsTreshold = 0;
    this.radGridView1.MasterView.TableSearchRow.SearchProgressChanged += TableSearchRow_SearchProgressChanged;
}

private void TableSearchRow_SearchProgressChanged(object sender, Telerik.WinControls.UI.SearchProgressChangedEventArgs e)
{
    if (e.SearchFinished == false && e.SearchCriteria != null && e.SearchCriteria != string.Empty)
    {
        Console.WriteLine("Search results: " + e.Cells.Count);
        foreach (GridSearchResultCellInfo c in e.Cells)
        {
            Console.WriteLine(c.RowInfo.Cells[c.ColumnInfo.Name].Value);
        }
    }
}

You can find additional information in the Search Row help article.

As to the filtering case, you can refer to our Demo application >> GridView >> Filtering >> Custom filtering example which uses the custom filtering functionality to hide the rows that do not match the criterion.

I hope this information helps. Should you have further questions I would be glad to help.

Hello Dess,

 

thank you for your feedback -- that is similar to how i approached the issue... only difference: i waited for e.SearchFinished == true.

It's not very intuitive that SearchProgressChangedEventArgs.Cells is NULL once the search is over.

 

I will modify my code accordingly.

 

Thanks again,

Andreas
