How to eliminate cell''s border in Grid control

[Allon]

Hi everyone,

I'd like to know how can I eliminate cell's border in Grid control (at runtime). I want it to be "None" (in top, bottom, left and right).

Thanks in advance :)

I forgot to mention something. My problem is that I don't know how to eliminate the border of the chosen cell in grid control. In my app I tried to cancel some cell selection, and return to the prev cell. Everything went well beside that the cell which supposed to be chosen (and afterword not) remains with his border. I know everything I need to make the unchosen cell a look like it has never chosen, beside it's border (this is the only property which I can't control at runtime).

Hi Allon
Thank you for using Syncfusion products.
The borders of the deselected cell to give the appearance of a normal cell can be achieved by handling the events: CellClick and CurrentCellControlDoubleClick.
CellClick event handler helps to select the cell and modify the cell border.
CurrentCellControlDoubleClick event handler helps to unselect the selected cell and resume the default border for the cell.

//create an object of the GridBorder Class and initialize it with required parameters value for removing the border of selected cells.
            gb=new GridBorder(GridBorderStyle.None,Color.Black,GridBorderWeight.Thick);
 
//create an object of the GridBorder Class and initialize it with required parameters value for setting the border of unselected cells.
            gb1 = new GridBorder(GridBorderStyle.Standard, Color.Black, GridBorderWeight.Thick);

void gridControl1_CurrentCellControlDoubleClick(object sender, ControlEventArgs e)
        {
            // gets the column index of the current cell
            int col1 = this.gridControl1.CurrentCellInfo.ColIndex;
            // gets the row index of the current cell
            int row1 = this.gridControl1.CurrentCellInfo.RowIndex;
            
            // assign the GridBorder Class "gb1" as value to the Borders.Bottom property of the control.
            this.gridControl1[row1, col1].Borders.Bottom = gb1;
            this.gridControl1[row1, col1].Borders.Right = gb1;
            this.gridControl1[row1, col1].Borders.Top = gb1;
            this.gridControl1[row1, col1].Borders.Left = gb1;
        }           
 
        void gridControl1_CellClick(object sender, GridCellClickEventArgs e)
        {
            // This ensures only selected cell will remove its border
            if (this.gridControl1.Selections.Count != 0)
            {
                int col1 = this.gridControl1.CurrentCellInfo.ColIndex;
                int row1 = this.gridControl1.CurrentCellInfo.RowIndex;
 
                this.gridControl1[row1, col1].Borders.Bottom = gb;             
                this.gridControl1[row1, col1].Borders.Top = gb;
                this.gridControl1[row1, col1].Borders.Left = gb;
            }
 
        }

Hi Lingaraj S.,

Thanks for the nice app. It will be very appreciated if you could add something that I need for my app. It goes like this: In the moment you click on any cell, a message will shown up, and ask you if you want to go back to the prev cell. If you'd click Yes, the usual thing will happen, but if you'd click No, the prev cell will be chosen, and that's it.

Thanks in advance :-)

Hi Lingaraj S.,

Sorry about the last request. This one will be much clearer.

It will be very appreciated if you could add something that I need for my app. It goes like this: In the moment you click on any cell, a message will shown up, and ask you if you want to go back to the prev cell. If you'd click No, the usual thing will happen, but if you'd click Yes, the prev cell will be chosen, and therefore, there will be no sign, that you planed to select another cell.

Thanks in advance :-)

Hi Allon,

Thanks for your update.

The requirement of moving to the previous cell on demand through messagebox, can be achieved through the following code.

if (MessageBox.Show("Go Previous Cell", "Previous Cell", MessageBoxButtons.YesNo) == DialogResult.Yes)
                {
                    // event is handled to repaint the clicked cell
                    this.gridControl1.PrepareViewStyleInfo += new GridPrepareViewStyleInfoEventHandler(gridControl1_PrepareViewStyleInfo);
                                       
                    newCol = col1 - 1;                    
                    // To move the cell selection to the previous cell
                    this.gridControl1.CurrentCell.MoveTo(row1, newCol , GridSetCurrentCellOptions.SetFocus);
                    
                    e.Cancel = true;

                }        


void gridControl1_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e)
        {
            // Checking the index of the clicked cell
            if (e.RowIndex == row1 && e.ColIndex == col1)

                // Setting the backcolor of the clicked cell
                e.Style.BackColor = Color.Black;
            
        }

Here is a sample in which this has been implemented.

Hi Ranjeet,

What you have sent me works very well, but I have little problem with that. I use CurrentCellActivated instead of CellClick, because the user can go through the rows with arrows keys (and not with the mouse). I use the grid control as listbox. What I want my app to do is when the user clicks some row, the app will ask him if he sure that he wants to do that selection. What always goes wrong is if the user selects No, everything is coming back to the original state except of the border of the canceled row. It remains solid black. If you want I can send you a piece of code to demonstrate what I mean.

Regrards,
Allon

Hi Allon

Thanks for your update.

Here is the code by which you may achieve the requirement.

                                // Enables multiple row selection
            this.gridControl1.ListBoxSelectionMode = SelectionMode.MultiExtended;           

            this.gridControl1.CurrentCellActivated += new EventHandler(gridControl1_CurrentCellActivated);


            // Moves the row focus to the previous row.
            this.gridControl1.CurrentCell.MoveTo(cc.row, cc.col, GridSetCurrentCellOptions.SetFocus);

You may find the sample with the above code implemented from the following location
