 on dropdownselected change我试图找到radnumeric文本框的控件并使其可见= true ..

 <   asp：标签    ID   =  lblUnitOfMeasure    runat   = 服务器   文字  ='  <％ #Eval（  UnitOfMeasure）％> '   可见  =  false >  <   / asp：标签 >  
 <   asp：DropDownList     ID   =  ddlUnitOfMeasure    runat   =  server   宽度  =  130px     OnSelectedIndexChanged   = < span class =code-keyword> ddlUnitOfMeasure_SelectedIndexChanged    AutoPostBack   =  true  >

 protected void ddlUnitOfMeasure_SelectedIndexChanged（object sender，EventArgs e）
 {
 foreach（rdgPanelDataPlane.EditItems中的GridDataItem项）
 {
 GridEditableItem itemToEdit =（GridEditableItem） ）item.EditFormItem; 
 DropDownList txtUnitOfMeasure =（DropDownList）itemToEdit.FindControl（ddlUnitOfMeasure）; 
 string s = txtUnitOfMeasure.Text; 
 ViewState [Changed] = txtUnitOfMeasure.Text; 
 // txtUnitOfMeasure.Visible = true; 
} 
 
} 
 
我试过这样但是testbox不可见。 
 
 DropDownList dropdownlist1 =（DropDownList）sender; 
 GridEditFormInsertItem item1 =（GridEditFormInsertItem）dropdownlist1.NamingContainer; 
 RadNumericTextBox textbox1 =（RadNumericTextBox）item1.FindControl（txtUnitOfMeasure）; 
 if（dropdownlist1.SelectedItem.Text ==Per Call Over）
 {
 textbox1.Visible = true; 
}
