设置Slider扩展器的最小值和最大值

I have a slider whose minimum and maximum value has to be taken from a label

我有一个滑块，其最小值和最大值必须从标签中获取

Following is the code

以下是代码

  <asp:SliderExtender ID="TextBox3_SliderExtender" runat="server" BehaviorID="TextBox3"
                       BoundControlID="TextBox4"  TargetControlID="TextBox3" EnableHandleAnimation="true" 
                       Maximum='<%# Math.Round(((double)lblMax.Text),0) %>' Minimum='<%# Math.Round((double)lblMin.Text,0) %>' Orientation="Horizontal" Steps="100" />

the error in above code is cannot convert type 'string to 'double'

上面代码中的错误是无法将'string'类型转换为'double'

how can i set maximum value from label named lblMax as Maximum for slider extender (Note : - lblMax contain integer value)

如何将名为lblMax的标签的最大值设置为最大滑块扩展器（注意： - lblMax包含整数值）

 Maximum='<%# Math.Round(((double)lblMax.Text),0) %>'

2 个解决方案

#1

You can't directly cast a string to a double. You're looking for double.Parse().

您不能直接将字符串转换为double。你正在寻找double.Parse（）。

#2

The minimum and maximum value can be set throught code as

最小值和最大值可以通过代码设置为

TextBox3_SliderExtender.Minimum = int.Parse(lblMin.Text.ToString()); TextBox3_SliderExtender.Maximum = int.Parse(lblMax.Text.ToString());

TextBox3_SliderExtender.Minimum = int.Parse（lblMin.Text.ToString（））; TextBox3_SliderExtender.Maximum = int.Parse（lblMax.Text.ToString（））;

that will pick the value from the label and we can assign dynamically the value to tha label

这将从标签中选择值，我们可以动态地将值分配给tha标签
