如果其中有一些重音字符，则IndexOf（）不起作用(IndexOf() is not working if there is some accent characters in it)

 我有datatable（dtblCostCategory），它具有以下值，我在下拉列表中使用它。 我从下拉列表中选择了值后保存了一些数据。 当我再次加载相同的页面时，未显示所选的值，而是在下拉列表中显示第一个值。  
        dsOtherDetails   

        CostCategory |  typeId  |  itemCount
        ----------------------------------------
          Softwaré   |    3     |     15

        dtblCostCategory

                CostCategory |  typeId    
               ----------------------------
                Electronics  |    1
                Groceries    |    2
                Softwaré     |    3


                cboCategory.DataSource = dtblCostCategory
                cboCategory.DataTextField = dtblCostCategory.Columns(1).ToString
                cboCategory.DataValueField = dtblCostCategory.Columns(0).ToString
                cboCategory.DataBind()

                Dim lstItem As New ListItem
                lstItem.Text = Server.HtmlEncode(Trim(CStr(dsOthersDetails.Tables(0).Rows(0).Item("CostCategory"))))
                lstItem.Value = Server.HtmlEncode(CStr(dsOthersDetails.Tables(0).Rows(0).Item("typeId")))
                cboCategory.SelectedIndex = cboCategory.Items.IndexOf(lstItem)
 
 在上面的代码中，我使用indexOf通过比较两个表中的值来获取所选索引。 由于类别（Softwaré）中有重音，indexOf无法正常工作。 有没有办法我可以选择索引忽略重音，以便下拉列表具有正确的选定值。 

I have datatable(dtblCostCategory) which has the following values which i use it in the dropdown. And i have saved some data after selecting the value from the dropdown. When i load the same page again the selected value is not being shown instead the first values is shown in dropdown. 
        dsOtherDetails   

        CostCategory |  typeId  |  itemCount
        ----------------------------------------
          Softwaré   |    3     |     15

        dtblCostCategory

                CostCategory |  typeId    
               ----------------------------
                Electronics  |    1
                Groceries    |    2
                Softwaré     |    3


                cboCategory.DataSource = dtblCostCategory
                cboCategory.DataTextField = dtblCostCategory.Columns(1).ToString
                cboCategory.DataValueField = dtblCostCategory.Columns(0).ToString
                cboCategory.DataBind()

                Dim lstItem As New ListItem
                lstItem.Text = Server.HtmlEncode(Trim(CStr(dsOthersDetails.Tables(0).Rows(0).Item("CostCategory"))))
                lstItem.Value = Server.HtmlEncode(CStr(dsOthersDetails.Tables(0).Rows(0).Item("typeId")))
                cboCategory.SelectedIndex = cboCategory.Items.IndexOf(lstItem)
 
In the above code I have used indexOf to get the selected index by comparing the values from two tables. As there is accent in category (Softwaré) the indexOf is not working properly. Is there way where I can get selected index ignoring the accents so that the drop down will have correct selected value.

 要获取所选行值，您可以使用：  
var records = Ext.getCmp('your_grid_id').getSelectionModel().getSelection(),
record  = records.length === 1 ? records[0] : null;
alert(record.get('a_row_title'); // specified in the model
 
 要将值设置为文本字段：  
Ext.getCmp('your_textField_id').setValue(record.get('...'));

To get the selected row values you can use: 
var records = Ext.getCmp('your_grid_id').getSelectionModel().getSelection(),
record  = records.length === 1 ? records[0] : null;
alert(record.get('a_row_title'); // specified in the model
 
To set the value to a text field: 
Ext.getCmp('your_textField_id').setValue(record.get('...'));

如果其中有一些重音字符，则IndexOf（）不起作用(IndexOf() is not working if there is some accent characters in it)
