DataGridView SelectionChanged EVENT

问题描述

你好，



在我的表格上有两个datagridview：



一个datagridview被填充DataBinding：

Hello,

On my form a have two datagridview:

One datagridview is filled by DataBinding:

private void controlContractePrincipalLoad(object sender, EventArgs e)
       {
           string NumeClientCautat = txtCautaDupaNume.Text;
           this.sClienti.DataSource = SetariAmanet.TotiClienti(NumeClientCautat);
       }

一个CellContentClick EVENT（它的作品）：

A CellContentClick EVENT (its works):

private void dVizualizareClientiCellContentClick(object sender, DataGridViewCellEventArgs e)
        {
            DataGridView vizualizare = sender as DataGridView;
            if (vizualizare != null)
            {
                IdClientSelectat = Convert.ToInt32(vizualizare.SelectedRows[0].Cells[0].Value.ToString());
                if (IdClientSelectat != 0)
                {
                    InformatiiDespreClientContracte();
                }
            }
        }

和SelectionChanged事件：

AND a SelectionChanged event:

private void dVizualizareClientiSelectionChanged(object sender, EventArgs e)
        {
            DataGridView vizualizare = sender as DataGridView;
            if (vizualizare != null)
            {
                IdClientSelectat = Convert.ToInt32(vizualizare.SelectedRows[0].Cells[0].Value.ToString());
                if (IdClientSelectat != 0)
                {
                    InformatiiDespreClientContracte();
                }
            }
        }

SelectionChanged事件不起作用

错误按摩是：索引超出范围。



SelectionChanged事件执行两次（我认为），我的IdClientSelectat第一次使用值，然后他在这一行给我一个错误：

The SelectionChanged event is not working
The error massage is: Index out of range.

The SelectionChanged event is executed two times (i think), the first time my IdClientSelectat hase a value, then he gives me an error at this line:

IdClientSelectat = Convert.ToInt32(vizualizare.SelectedRows[0].Cells[0].Value.ToString());

问题出在哪里？

Where is the problem?

推荐答案

if (vizualizare != null && vizualizare.Rows.Count > 0 && vizualizare.Columns.Count > 0)
