TemplateField
次のように、s とグリッド ビューのOnRowCommand
イベントを使用します。
マークアップ:
<asp:gridview id="GridView1"
OnRowCommand="GridView1_RowCommand"
runat="server">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:TextBox ID="TextBoxDrawing" runat="server"
Text="<%# Eval("Drawing")) %>" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:Button ID="selc" runat="server" Text="View"
CommandName="View"
CommandArgument="<%# ((GridViewRow)Container).RowIndex %> />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
分離コード:
protected void GridView1_RowCommand(Object sender, GridViewCommandEventArgs e)
{
// If multiple buttons are used in a GridView control, use the
// CommandName property to determine which button was clicked
if(e.CommandName == "View")
{
// Convert the row index stored in the CommandArgument
// property to an integer
var index = Convert.ToInt32(e.CommandArgument);
// Retrieve the row that contains the button clicked
// by the user from the Rows collection
var row = GridView1.Rows[index];
// Find the drawing value
var theDrawingTextBox = row.FindControl("TextBoxDrawing") as TextBox;
// Verify the text box exists before we try to use it
if(theDrawingTextBox != null)
{
var theDrawingValue = theDrawingTextBox.Text;
// Do something here with drawing value
}
}
}
