我需要在TextBox中替换“_”字符,该字符用MaskedEditExtender包装,以在编辑TextBox时验证数据输入。
<asp:MaskedEditExtender ID="TextBox1_MaskedEditExtender" runat="server"
CultureAMPMPlaceholder="" CultureCurrencySymbolPlaceholder=""
CultureDateFormat="" CultureDatePlaceholder="" CultureDecimalPlaceholder=""
CultureThousandsPlaceholder="" CultureTimePlaceholder="" Enabled="True"
InputDirection="RightToLeft" Mask="9999.9" MaskType="Number"
TargetControlID="TextBox1" ClearTextOnInvalid="False>
</asp:MaskedEditExtender>
当我尝试编辑行时。文本框值为“__12.4”。在GridView1_RowUpdating中,我试图将“_”替换为“”而没有结果。
protected void GridView1_RowUpdating(object sender, System.Web.UI.WebControls.GridViewUpdateEventArgs e)
{
TextBox Textbox1 = (TextBox)GridView1.Rows[e.RowIndex].FindControl("Textbox1 ");
Label Label2 = new Label();
Label2.Text = TextBox1.Text.Replace("_", "");
GridView1.DataBind();
}
我的TemplateField看起来像这样
<asp:TemplateField HeaderText="Decimal Value" SortExpression="DecimalValue">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("DecimalValue","{0:F1}") %>' Height="20px" MaxLength="6" Width="40px"></asp:TextBox>
<%-- Formated to display 9999.9 per requirement --%>
<asp:MaskedEditExtender ID="TextBox1_MaskedEditExtender" runat="server"
CultureAMPMPlaceholder="" CultureCurrencySymbolPlaceholder=""
CultureDateFormat="" CultureDatePlaceholder="" CultureDecimalPlaceholder=""
CultureThousandsPlaceholder="" CultureTimePlaceholder="" Enabled="True"
InputDirection="RightToLeft" Mask="9999.9" MaskType="Number"
TargetControlID="TextBox1" ClearTextOnInvalid="False">
</asp:MaskedEditExtender>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%# Bind("DecimalValue", "{0:F1}") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
我不知道在更新行之后更新TextBox1.text值的位置并将其发送到MS SQL数据库。

我认为问题是当你选择行时,因为你选择了行,采取文本框但从不更改值:
protected void GridView1_RowUpdating(object sender, System.Web.UI.WebControls.GridViewUpdateEventArgs e)
{
TextBox Textbox1 = (TextBox)GridView1.Rows[e.RowIndex].FindControl("Textbox1 ");
Label Label2 = new Label();
Label2.Text = GridView1.Text.Replace("_", "");
GridView1.DataBind();
}
我认为(见下面的代码)
protected void GridView1_RowUpdating(object sender, System.Web.UI.WebControls.GridViewUpdateEventArgs e)
{
TextBox Textbox1 = (TextBox)GridView1.Rows[e.RowIndex].FindControl("Textbox1 ");
Label Label2 = new Label();
Label2.Text = Textbox1.Text.Replace("_", ""); //Replace Gridview for the text box
GridView1.DataBind();
}
但是这里只有你将替换Character并放入Label,它不会更新texbox。
啦啦队

如果你有一个数据源处理更新,你不需要在rowupdating中数据化你的gridview,你能试试看看会发生什么吗?
protected void GridView1_RowUpdating(object sender, System.Web.UI.WebControls.GridViewUpdateEventArgs e)
{
TextBox Textbox1 = (TextBox)GridView1.Rows[e.RowIndex].FindControl("Textbox1");
Textbox1.Text = Regex.Replace(Textbox1.Text, "_", "");
}
