I want to achieve functionality of Re-Ordering Rows In a Grid.

Requirement:
User will Select Row and Click on Up Button on UI to shift that on Up direction. Example If user select 3rd row from top and then click on up then it must shift that row to 2 position from top.
Also the which was on 2nd postion from top now comes on 3rd from top 

Below code I tried but not working Properly When Rows are More than 2 in a grid:

private void btnInternalUp_Click(object sender, EventArgs e)
    {

for (int index = 0; index < this.m_grdGridControl.SelectedRows.Count; index++)
{
var currentRow = this.m_grdGridControl.SelectedRows[index];
int currentIndex = currentRow.Index;
int nextIndex = NextIndex(this.m_grdGridControl, currentIndex, "up");                    
this.m_grdGridControl.MasterTemplate.Rows.Move(currentIndex, nextIndex);
   
}

    }

//NextIndexMethod Return the index where row need to be shifted:

public static int NextIndex(RadGridView grd,int currentIndex,string direction)
    {
        int nextIndex;
        if (direction.ToLower() == "up")
        {
            if(currentIndex == 0)
            {
                nextIndex = 0;
            }
            else
            {
                nextIndex = currentIndex - 1;
            }
        }
        else
        {
            if(currentIndex == grd.Rows.Count - 1)
            {
                nextIndex = currentIndex;
            }
            else
            {
                nextIndex = currentIndex + 1;
            }
        }

        return nextIndex;
    }

Hello All,
Below mentioned is the piece of code which works for me and I hope it would helpful for others as well so sharing my code.

/---Code---

//this.m_grdGridControl this is 

 if (this.m_grdGridControl.SelectedRows.Count > 0)
            {
                for (int i = 0; i < this.m_grdGridControl.SelectedRows.Count; i++)
                {
                    var currentRow = this.m_grdGridControl.SelectedRows[i];
                    int currentIndex = currentRow.Index;
                    int nextIndex = NextIndex(this.m_grdGridControl, currentIndex, "down");
                    this.m_grdGridControl.Rows.Move(currentIndex, nextIndex);
                }

            }

//Next Index Method will decide destination index of selected current row

private int NextIndex(RadGridView grd, int currentIndex, string direction)
    {
        int nextIndex;
        if (direction.ToLower() == "up")
        {
            if (currentIndex == 0)
            {
                nextIndex = 0;
            }
            else
            {
                nextIndex = currentIndex - 1;
            }
        }
        else
        {
            if (currentIndex == grd.Rows.Count - 1)
            {
                nextIndex = currentIndex;
            }
            else
            {
                nextIndex = currentIndex + 1;
            }
        }

        return nextIndex;
    }

Hi, Shubham,

I am glad that you have found a suitable solution that works for your scenario. I have reviewed the provided code snippet and it seems OK to me. As to the previously referred forum thread, could you please specify why this approach is not applicable for your case? It also swaps the cells' values and thus moves the rows.
