我设计了一个grid control 20行3列。 在第一列中我已经输入了一些硬编码的字符串,在第二列中,我想将checkBox与选中的未检查行为相关联,以便用户可以对其进行修改。我在下面的代码中为QueryCellInfo事件编写了代码,但它不起作用。如何使CheckBox选中或取消选中,以便用户可以在Grid Control中对其进行修改?

我该如何完成它?

请提出建议。

下面是我的代码部分:

public partial class Form1 : Form 
{ 
    System.Windows.Forms.Timer t1 = new System.Windows.Forms.Timer(); 
    private Syncfusion.Windows.Forms.Grid.GridControl gridControlDownloadScript = new Syncfusion.Windows.Forms.Grid.GridControl(); 
    public Form1() 
    { 
     // this.gridControl1.GridVisualStyles = Syncfusion.Windows.Forms.GridVisualStyles.Metro; 
     InitializeComponent(); 

    } 

    private void Form1_Load(object sender, EventArgs e) 
    { 

     gridControl1.Model.RowCount = 20; 
     gridControl1.Model.ColCount = 3; 
     this.gridControl1.VScrollPixel = true; 
     this.gridControl1.HScrollPixel = true; 


     this.gridControl1[0, 1].Text = "EMPLOYEE"; 
     this.gridControl1[0, 2].Text = "CHECKBOX"; 
     this.gridControl1[0, 3].Text = " "; 
     this.gridControl1[1, 1].Text = "Rahul Verma"; 
     this.gridControl1[2, 1].Text = "MAnish Desai"; 
     this.gridControl1[3, 1].Text = "Mohan Pothala"; 
     this.gridControl1[4, 1].Text = "Dhanraj Dhoke"; 

     gridControl1.Model.RowCount = 20; 

     gridControl1.Model.ColCount = 3; 
     gridControl1.QueryCellInfo += new GridQueryCellInfoEventHandler(GridQueryCellInfo); 
     gridControl1.SaveCellInfo += new GridSaveCellInfoEventHandler(GridSaveCellInfo); 
     gridControl1.QueryRowCount += gridControl1_QueryRowCount; 
     gridControl1.QueryColCount += gridControl1_QueryColCount; 
     this.gridControl1.HScrollBehavior = GridScrollbarMode.Disabled; 
     this.gridControl1.VScrollBehavior = GridScrollbarMode.Disabled; 

     this.gridControl1.ColWidths.ResizeToFit(GridRangeInfo.Cols(1, 1)); 

     this.gridControl1.RowHeights.ResizeToFit(GridRangeInfo.Rows(1, 20)); 


     t1.Interval = 250; 

     t1.Tick += new EventHandler(IncreaseProgressBar); 



    } 

    private void CellClick(object sender, GridCellClickEventArgs e) 
    { 
    } 



    private void IncreaseProgressBar(object sender, EventArgs e) 
    { 
     progressBar1.Increment(5); 
     progressBar1.Minimum = 0; 
     progressBar1.Maximum = 100; 


     lblProgress.Text = progressBar1.Value.ToString() + "%"; 

     if (progressBar1.Value == progressBar1.Maximum) 

      t1.Stop(); 
    } 

    private void gridControl1_QueryColCount(object sender, GridRowColCountEventArgs e) 
    { 

    } 

    private void gridControl1_QueryRowCount(object sender, GridRowColCountEventArgs e) 
    { 

    } 

    private void GridQueryCellInfo(object sender, GridQueryCellInfoEventArgs e) 
    { 
     int i = 0; 
     while (i++ < 4) 
     { 
      if (i == 0 || i == 1 || i == 4 || i == 6 || i == 9 || i == 11 || i == 14) 
      { 

       continue; 

      } 
      else if (e.RowIndex == i && e.ColIndex == 2) 
      { 

       e.Style.CellType = GridCellTypeName.CheckBox; 

       e.Style.Description = ""; 
     this.gridControl1[i, 2].CheckBoxOptions = new GridCheckBoxCellInfo("True", "False", string.Empty, false); 
       e.Style.CheckBoxOptions.CheckedValue = "true"; 
       e.Style.CellValue = "true"; 

      } 

     } 
     if (e.RowIndex > 0 && e.ColIndex > 0) 
     { 


     } 
    }

您使用的是什么技术?赢表格? WPF?此外,您只是想让用户修改它们的“按需”是什么意思? – Emad

@Emad,我正在使用win forms.yes,我希望用户修改它们。 对不起。 –

您可以手动执行此操作使用网格属性定义手动设置为复选框列列的属性,然后它会表现为你想

QueryCellInfo事件将触发单元GridControl。根据您的代码,您在QueryCellInfo事​​件中将单元格值设置为true。因此,CellValue复选框将始终保持为真。如果您希望用户修改CheckedValue,请在Form_Load()方法中将该特定单元的CellValue设置为“True”。请参考下面的代码, 代码片段 this.gridControl1 [2,2] .CellValue =“True”; this.gridControl1 [3,2] .CellValue =“True”;
