RadTreeList SelectedIndexChanged事件产生前一个值作为输出 [英] RadTreeList SelectedIndexChanged Event producing the previous value as Output

问题描述

尊敬的先生/女士，



RadTreeList SelectedIndexChanged事件产生前一个值为输出



考虑，在treeList中，我有数据项A - > 977，B ---> 978，C ---> 979



如果我选择B- - > 978表示将生成o / p为A - > 977

Dear Sir/Madam,

RadTreeList SelectedIndexChanged Event producing the previous value as Output

consider, In treeList, i have dataitems A-->977,B--->978, C--->979

If i select B-->978 means that will produce the o/p as A-->977

protected void RadTreeList1_SelectedIndexChanged(object sender,EventArgs e)
        {
            
            foreach (TreeListDataItem grddt in RadTreeList1.SelectedItems)
            {
                int product_id = Convert.ToInt32(grddt.GetDataKeyValue("product_id"));

            }
            
        }

如果我选择B表示，它会产生结果A.

我需要显示，如果我们A意味着A，B意味着B



怎么办

请帮帮我

if i select the B means, it produce the result A.
I need to display if we A means A, B means B

How to do
Please Help me

Thanks in Advance

推荐答案

您好Tusharsangani，

尝试从中获取索引事件处理程序那是

Hi Tusharsangani,
Try to get the index from event handler e. That is

e.SelectedIndex
