GridView SearchRow capitalize

Hello, özer,

According to the provided information and screenshot, it seems that you need to search by lower case letters and find the capital case letters in the grid rows. Please correct me if I am wrong. It is possible to create a custom GridViewSearchRowInfo and override its MatchesSearchCriteria method which returns true/false. Thus, you can control which rows to match the filter. A sample approach how to plug into the search functionality and change the default logic is demonstrated here: 

https://docs.telerik.com/devtools/winforms/knowledge-base/starts-with-search-in-radgridview 

You can use it as a starting point for achieving the custom implementation you need.

It is possible to specify the Culture at application level by setting the System.Threading.Thread.CurrentThread.CurrentCulture property to the desired culture. It is also possible to specify a culture for a particular column in the grid by setting the column's FormatInfo property. Note that the search functionality in RadGridView is purposed to search for the matches considering the formatted cells' values /not the raw cell's value/ according to the applied culture to the column. It is worth considering the custom filtering functionality that RadGridView uses. In many cases, it is appropriate to replace the search functionality with the custom filtering like demonstrated in the following KB article:

I hope this information helps. If you need any further assistance please don't hesitate to contact me.

Hi Dess. 

Sorry I'm a little late in responding.

I tried both methods but they didn't work.

public RadForm1()
{
    InitializeComponent();

    this.radGridView1.AllowSearchRow = true;

    this.radGridView1.CurrentRowChanging += RadGridView1_CurrentRowChanging;
}

private void RadGridView1_CurrentRowChanging(object sender, CurrentRowChangingEventArgs e)
{
    if (e.NewRow is GridViewSearchRowInfo)
    {
        e.Cancel = true; // I put a breakpoint here, but it never stopped here 
    }
}


private void radGridView1_CreateRowInfo(object sender, GridViewCreateRowInfoEventArgs e)
{
    if (e.RowInfo is GridViewSearchRowInfo)
    {
         e.RowInfo = new CustomSearchRow(e.ViewInfo); //likewise i put a breakpoint here but it never stopped here either
    }
}

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

    protected override bool MatchesSearchCriteria(string searchCriteria, GridViewRowInfo row, GridViewColumn col)
    {
        return (row.Cells[col.Name].Value + "").StartsWith(searchCriteria); 
    }
}

Changing the cultureinfo didn't work for me, unfortunately.

The keypress event of the grid is also not fired on the search row. It acts as if the search row is a separate component rather than a part of the grid.

Hi Dess. 

Sorry again I'm a little late in responding.

I had subscribed to the CreateRowInfo event at runtime, now fixed it as you said and subscribed at design time and I made a small change in the MatchesSearchCriteria method.

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

        protected override bool MatchesSearchCriteria(string searchCriteria, GridViewRowInfo row, GridViewColumn col)
        {
            searchCriteria = searchCriteria.ToUpper(); 
            return (row.Cells[col.Name].Value + "").Contains(searchCriteria);
        }
    }

The result serves its purpose, although not exactly what I want it to be. Thank you very much
