Tooltip of the cell text when text is longer than cell width

[Gaukhar Massabayeva]

Hi,

 

I am looking for a way to

 

1) set a tooltip text (something along the lines of e.Style.CellTipText = e.Style.Text) IF the Text inside the cell is longer than the width of that cell.

 

2) the tooltip display time should be customisable.

 

Please let me know how can this be achieved. Thank you

Oh and the tooltip should be available in nested rows as well.

Hi Gaukhar Massabayeva,

 

Thank you for your interest in Syncfusion.

 

Sorry for the inconvenience caused with delay we have analyzed your query with the provided details. You can set the tooltip for the cells which contain the large text using the PrepareViewSyleInfo event please refer the following codes for your references.

 

void gridControl1_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e)

        {

            //e.Style.CellTipText = e.Style.Text;

 

            GridCurrentCell cc = this.gridControl1.CurrentCell;

            GridTextBoxCellRenderer rend = this.gridControl1.CurrentCellRenderer as GridTextBoxCellRenderer;

            if (rend != null)

            {

                int textLength = rend.Control.Text.Length * 6;

                if (this.gridControl1.ColWidths[cc.ColIndex] < textLength)

                    e.Style.CellTipText = e.Style.Text;

                else

                    e.Style.CellTipText = "";

            }

        }

 

 

2. To customize the tooltip text display by the AutoPopDelay code. Please refer the following code to delay.

 

this.gridControl1.CellToolTip.AutoPopDelay = 1000;

 

 

Please refer the attached sample file also which contain the above workaround and let me know if you need any more helps regarding this. We will provide better solution for you.

Hi Thank you for getting back to me.

 

I tried the sample you provided. It works great. However, once the is a column detected whose text exceeds the colwidth for some reason tooltip starts to appear for all cell, even if the text length does not exceed colwidth. :S

Hi Gaukhar,

 

Sorry for the inconvenience caused.

 

Query show tool tip on a grid grouping control cell, if text length is greater than the width of the column

We have deeply analyzed your query to show tool tip on a if text length is greater than the width of the column. You can use  the TableControl’s MouseMove event and check whether the cell text length is greater than the cell’s column width, if the text length is larger than the column width then show the tooltip with cell's text.   This can be achieved by "Active" property of the tooltip object. The following code explains the same.     Please use the attached sample file also.   Sample file : http://www.syncfusion.com/downloads/Support/DirectTrac/105872/GGC_CustomToolTip-838514140.zip

 

Please let me know if you have any concerns.

I would like to achieve the same thing except the code help is not showing in this thread.

Hi Adam, 

Thanks for contacting Syncfusion support. 

To set tooltip text for cells whose cellvalue is longer than the column width of the grid cell, MouseMove event can be used. To check the cell text length is greater than the cell’s column width, GetMeasureString() method can be used. Please refer to the below code and sample, 

 

Code Example 

//Event Triggering          

gridControl1.MouseMove += GridControl1_MouseMove; 

 

//Event Customization   

private void GridControl1_MouseMove(object sender, MouseEventArgs e) 

{ 

    int row, col; 

    Point p = new Point(e.X, e.Y); 

    gridControl1.PointToRowCol(p, out row, out col); 

    GridStyleInfo style = gridControl1[row, col] as GridStyleInfo; 

    if(style!=null) 

    { 

        Graphics g = gridControl1.CreateGraphics(); 

        float a = g.MeasureString(style.CellValue.ToString(), style.GdipFont).Width; 

        if (this.gridControl1.ColWidths[col] < a) 

        { 

            style.CellTipText = style.Text; 

        } 

        else 

            style.CellTipText = ""; 

    } 

}
