我有一个GridView,它有10个由CheckBoxes填充的列。但是,有没有办法通过使用循环来获取FindControl()
值,而不是使用CheckBox.Checked
?
当前代码:
if (e.CommandName == "updaterow")
{
int index = Convert.ToInt32(e.CommandArgument);
GridViewRow selectedRow = GridView1.Rows[index];
// TableCell BranchCode = selectedRow.Cells[0];
CheckBox cb101 = (CheckBox)selectedRow.FindControl("cb101");
CheckBox cb102 = (CheckBox)selectedRow.FindControl("cb102");
//...and so on
}
ASPX代码:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" OnRowCommand="GridView1_RowCommand">
<Columns>
<asp:TemplateField HeaderText="101">
<ItemTemplate>
<asp:CheckBox runat="server" id="cb101" AutoPostBack="false" Checked='<%# Eval("101").ToString()=="1" ? true : false %>' Enabled='<%#(String.IsNullOrEmpty(Eval("101").ToString()) ? false: true) %>'/>
</ItemTemplate>
</asp:TemplateField>
....and so on
<asp:ButtonField ButtonType="Button" CommandName="updaterow" Text="Update"/>
</Columns>
</asp:GridView>

试试这个,
使用foreach
循环:
foreach (GridViewRow row in GridView1.Rows)
{
CheckBox chk = row.Cells[0].Controls[0] as CheckBox;
if (chk != null && chk.Checked)
{
// ...
}
}
在OnRowCommand
事件中使用它并获取CheckBox值。
GridViewRow row = (GridViewRow)(((Control)e.CommandSource).NamingContainer);
int requisitionId = Convert.ToInt32(e.CommandArgument);
CheckBox cbox = (CheckBox)row.Cells[3].Controls[0];

要运行GridView的所有行,请不要使用for
循环,请使用foreach
循环:
foreach (GridViewRow row in yourGridName.Rows) //Running all lines of grid
{
if (row.RowType == DataControlRowType.DataRow)
{
CheckBox chkRow = (row.Cells[0].FindControl("chkRow") as CheckBox);
if (chkRow.Checked)
{
//if checked do something
}
}
}

您想为网格视图中的所有行创建一个独立的for循环,然后参考以下链接
http://nikhilsreeni.wordpress.com/asp-net/checkbox/
选择Gridview中的所有复选框
CheckBox cb = default(CheckBox);
for (int i = 0; i <= grdforumcomments.Rows.Count – 1; i++)
{
cb = (CheckBox)grdforumcomments.Rows[i].Cells[0].FindControl(“cbSel”);
cb.Checked = ((CheckBox)sender).Checked;
}
Select checked rows to a dataset; For gridview multiple edit
CheckBox cb = default(CheckBox);
foreach (GridViewRow row in grdforumcomments.Rows)
{
cb = (CheckBox)row.FindControl("cbsel");
if (cb.Checked)
{
drArticleCommentsUpdates = dtArticleCommentsUpdates.NewRow();
drArticleCommentsUpdates["Id"] = dgItem.Cells[0].Text;
drArticleCommentsUpdates["Date"] = System.DateTime.Now;dtArticleCommentsUpdates.Rows.Add(drArticleCommentsUpdates);
}
}

如果您需要findcontrol以外的方法,请尝试以下方法:
GridViewRow row = Gridview1.SelectedRow;
int CustomerId = int.parse(row.Cells[0].Text);// to get the column value
CheckBox checkbox1= row.Cells[0].Controls[0] as CheckBox; // you can access the controls like this

foreach (DataRow row in DataRow row in GridView1.Rows)
{
foreach (DataColumn c in GridView1.Columns)
bool ckbVal = (bool)(row[c.ColumnName]);
}

块引用
foreach (GridViewRow row in tempGrid.Rows)
{
dt.Rows.Add();
for (int i = 0; i < row.Controls.Count; i++)
{
Control control = row.Controls[i];
if (control.Controls.Count==1)
{
CheckBox chk = row.Cells[i].Controls[0] as CheckBox;
if (chk != null && chk.Checked)
{
dt.Rows[dt.Rows.Count - 1][i] = "True";
}
else
dt.Rows[dt.Rows.Count - 1][i] = "False";
}
else
dt.Rows[dt.Rows.Count - 1][i] = row.Cells[i].Text.Replace(" ", "");
}
}

foreach (GridViewRow row in GridView1.Rows)
{
CheckBox chkbox = (CheckBox)row.FindControl("CheckBox1");
if (chkbox.Checked == true)
{
// Your Code
