GridView SearchRow

[VLADISLAV]

using this code  part to exclude summaryRows from Search loop. 

#code

public class SearchRow : GridViewSearchRowInfo
{
    public SearchRow(GridViewInfo viewInfo) : base(viewInfo)
    {
    }
 
    protected override bool MatchesSearchCriteria(string searchCriteria, GridViewRowInfo row, GridViewColumn col)
    {
        if (row is GridViewSummaryRowInfo)
        {
            return false;
        }
        return base.MatchesSearchCriteria(searchCriteria, row, col);
    }
}
 
private void radGridView1_CreateRowInfo(object sender, GridViewCreateRowInfoEventArgs e)
{
    if (e.RowInfo is GridViewSearchRowInfo)
    {
        e.RowInfo = new SearchRow(e.ViewInfo);
    }
}

#code

And now i cant itterate through search results, i can only choose the first one and the last one​.

Without this code everythng works great, i mean i can iterate through search results, but when Searchrow finds empty cell in searchRow it throws exception.

[VLADISLAV]

"but when Searchrow finds empty cell in 'searchRow' it throws exception." i mean in SummaryRow

Any solution?

Hello Vladislav,

Thank you for writing.

Following the provided information, I was unable to replicate the error you are facing. Could you please specify the exact steps how to reproduce the problem? Alternatively, you can open a support ticket with a sample project so I can investigate the precise case.

Note that you can access the search results in the RadGridView.MasterView.TableSearchRow.SearchProgressChanged event. Here is a sample code snippet:

public Form1()
{
    InitializeComponent();

    this.radGridView1.AllowSearchRow = true;
    this.radGridView1.DataSource = this.ordersBindingSource;

    GridViewSummaryItem summaryItem = new GridViewSummaryItem();
    summaryItem.Name = "ShipName";
    summaryItem.Aggregate = GridAggregateFunction.Count;
    GridViewSummaryRowItem summaryRowItem = new GridViewSummaryRowItem();
    summaryRowItem.Add(summaryItem);
    this.radGridView1.SummaryRowsTop.Add(summaryRowItem);

    this.radGridView1.MasterView.TableSearchRow.InitialSearchResultsTreshold = 0;
    this.radGridView1.MasterView.TableSearchRow.SearchProgressChanged += TableSearchRow_SearchProgressChanged;
}

private void TableSearchRow_SearchProgressChanged(object sender, 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);
        }
    }
}

private void Form1_Load(object sender, EventArgs e)
{
    this.ordersTableAdapter.Fill(this.nwindDataSet.Orders);
}

public class SearchRow : GridViewSearchRowInfo
{
    public SearchRow(GridViewInfo viewInfo) : base(viewInfo)
    {
    }

    protected override bool MatchesSearchCriteria(string searchCriteria, GridViewRowInfo row, GridViewColumn col)
    {
        if (row is GridViewSummaryRowInfo)
        {
            return false;
        }
        return base.MatchesSearchCriteria(searchCriteria, row, col);
    }
}

private void radGridView1_CreateRowInfo(object sender, GridViewCreateRowInfoEventArgs e)
{
    if (e.RowInfo is GridViewSearchRowInfo)
    {
        e.RowInfo = new SearchRow(e.ViewInfo);
    }
}

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