DataGridView在開始時沒有選擇行

Question

在我的WinForms中我有DataGridView。我想一次選擇全行，所以我設置SelectionMode爲FullRowSelect。現在我遇到了問題，因爲在開始時我的表格強調了第一行（選定的行是空的，第一行沒有被選中，只是下劃線）。我嘗試了很多東西，比如：

private void dataGridView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e) 
    { 
     dataGridView1.ClearSelection(); 
    } 

而且都失敗了，因爲其實沒有選擇。

我該如何擺脫這個下劃線？

感謝您的幫助！

Answer 1

不幸的是，這些答案都沒有幫助我，但我找到了其他解決方案。相反，無法選擇的，我將只是這段代碼隱藏：

dataGridView1.DefaultCellStyle.SelectionBackColor = dataGridView1.DefaultCellStyle.BackColor; 
dataGridView1.DefaultCellStyle.SelectionForeColor = dataGridView1.DefaultCellStyle.ForeColor; 

所以如果有人只是想隱藏選擇它會工作得很好。

乾杯:)

這個工作對我來說：

private void dataGridView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e) 
{ 
    dataGridView1.Rows[0].Selected = false; 
} 

Answer 3

嘗試InitializeComponent()後在構造函數中設置DataGridView.AllowUserToAddRows = false。

Answer 4

這項工作對我來說是明確的選擇在數據綁定

Protected Sub GridCancel_DataBinding(sender As Object, e As EventArgs) Handles GridCancel.DataBinding 
    GridCancel.SelectedIndex = -1 

End Sub 

Answer 5

只要把dataGridView1.ClearSelection();在窗體的加載事件。

Answer 6

你可以叫dataGridView.ClearSelection（）Form_Load事件像這裏面的方法...

private void Form1_Load(object sender, EventArgs e) 
    { 
    // You will get selectedCells count 1 here 
    DataGridViewSelectedCellCollection selectedCells = dataGridView.SelectedCells; 
    // Call clearSelection 
    dataGridView.ClearSelection(); 
    // Now You will get selectedCells count 0 here 
    selectedCells = dataGridViewSchedule.SelectedCells; 
    }

，如果你要選擇行中你應該嘗試把中顯示事件datagridView.ClearCelection()，也datagridView.CurrentCell=null和例如刪除或修改信息只是做if(datagridView.CurrentCell==null){ MessageBox.Show("You must select row");}它爲我工作

Answer 8

在開始爲殘疾選擇行設置的事件是這樣的， 和管理FLAG停止ClearSelection

private void dataGridView_SelectionChanged(object sender, EventArgs e) 
{ 

    if (FLAG==true) 
    { 
     dataGridView.ClearSelection(); 
     FLAG=false; 
    } 
} 

Answer 9

嘗試，這會很有幫助

private void dgv_order_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e) 
     { 
      dgv_order.CurrentCell.Selected = false; 
      dgv_order.ClearSelection(); 
     }

有時，當你重裝你的窗體不關閉程序，第一行會可以高亮顯示。但它不會被選中，您將爲選定的行索引獲取-1。

你可以做到這一點就像這樣：

'1. store default styles when form is loading: 
Public Class aRoots 
Dim df1, df2, df3, df4 As Color 
Private Sub aRoots_Load(sender As Object, e As EventArgs) Handles Me.Load 
     df1 = DGV_Root.DefaultCellStyle.SelectionBackColor 
     df2 = DGV_Root.DefaultCellStyle.BackColor 
     df3 = DGV_Root.DefaultCellStyle.SelectionForeColor 
     df4 = DGV_Root.DefaultCellStyle.ForeColor 
...... 
'2. change cell styles when interacting with datagridview: 
Private Sub LoadRoot() 
     For i = 0 To 5 
       DGV_Root.Rows.Add() 
       For j = 0 To 3 
        DGV_Root.Item(j, i).Value = ... 
       Next 
      Next 
     'DGV_Root.ClearSelection() ==> instead of this use 2 lines below 
     DGV_Root.DefaultCellStyle.SelectionBackColor = df2 
     DGV_Root.DefaultCellStyle.SelectionForeColor = df4 
    End Sub 
'3. Change cell styles to default when selection is being changed like cell_click or cell_double click: 
Private Sub DGV_Root_CellMouseClick(sender As Object, e As DataGridViewCellMouseEventArgs) Handles DGV_Root.CellMouseClick 
     DGV_Root.DefaultCellStyle.SelectionBackColor = df1 
     DGV_Root.DefaultCellStyle.SelectionForeColor = df3 
... 
End Sub 
'4. restore all to default when u want to close form: 
Private Sub PbClose_Click(sender As Object, e As EventArgs) Handles PbClose.Click 
     BtnCancel.PerformClick() 
     DGV_Root.DefaultCellStyle.SelectionBackColor = df1 
     DGV_Root.DefaultCellStyle.BackColor = df2 
     DGV_Root.DefaultCellStyle.SelectionForeColor = df3 
     DGV_Root.DefaultCellStyle.ForeColor = df4 
     Me.Close() 
End Sub 

希望這有助於ü傢伙。

如果是這樣，因爲它提出了在初始加載不需要GridView1_SelectionChanged事件，你可以用一個標誌來處理這個

public partial class YourFormName 
{ 
    private bool IsReady= false; 

    private void YourFormName_Load(object sender, EventArgs e) 
    { 
      //Load your GridView1... 
      //Format your GridView1... 
      IsReady = true; 
    } 
    void GridView1_SelectionChanged(object sender, EventArgs e) 
    { 
     if (!IsReady) 
      return; 
     //do the rest of the stuffs 
    } 
}
