按文本查找DropDownList索引

Question

我有一个填充的DropDownList。如何找到Text值为“x”的索引？

Answer 1

如果你想在服务器端获得价值，你可以遵循这个。

ddlsample.SelectedIndex = ddlsample.Items.IndexOf(ddlsample.Items.FindByValue("x")); // If you want to find text by value field.
ddlsample.SelectedIndex = ddlsample.Items.IndexOf(ddlsample.Items.FindByText("x"));// If you want to find text by TextField.

Answer 2

试试。

ddlsample2.SelectedIndex = ddlsample.FindStringExact（ddlsample.Text）;
