单选按钮焦点问题 [英] Radio Button focus Issue

问题描述

我在单选按钮列表检查更改事件中写了以下代码

I have written below code in radio button list check change event

protected void rblStatus_SelectedIndexChanged(object sender, EventArgs e)
    {
        //To get focus on radio button which is selected
        var script = string.Format("document.getElementById('{0}_{1}').focus();", rblStatus.ClientID, rblStatus.SelectedIndex);

        if (ScriptManager.GetCurrent(this) != null && ScriptManager.GetCurrent(this).IsInAsyncPostBack)
        {
            ScriptManager.RegisterStartupScript(rblStatus, typeof(RadioButtonList), Guid.NewGuid().ToString(), script, true);
        }
        else
        {
            ClientScript.RegisterStartupScript(typeof(RadioButtonList), Guid.NewGuid().ToString(), script, true);
        }

        //	Open - 1
        //  Close - 2
        //	Extension - 3
        //  Completion - 4	
        //	Inprogress - 5
        
        List<CorrectiveActionExtension> correctiveActionStatus = new List<CorrectiveActionExtension>();
        correctiveActionStatus = (List<CorrectiveActionExtension>)ViewState["dataSource"];

        int i = 0;
        foreach (CorrectiveActionExtension CAItem in correctiveActionStatus)
        {

            if (i == int.Parse(ViewState["index"].ToString()))
            {
                txtDescription.Text = CAItem.Remarks.ToString();

                if (rblStatus.SelectedValue.Equals("3"))
                {
                    divTargetDate.Visible = true;
                    ulTargetDate.DateTime = (CAItem.TargetDate == null ? DateTime.Now : CAItem.TargetDate);
                }
                else
                {
                    divTargetDate.Visible = false;
                    ulTargetDate.DateTime = null;
                   // txtDescription.T
                }

            }
            i++;
        }
        mdlChangeStatus.Show();
    }

用于关注单选按钮列表的代码是

In which code used to get focus on radio buttonlist is

var script = string.Format("document.getElementById('{0}_{1}').focus();", rblStatus.ClientID, rblStatus.SelectedIndex);

        if (ScriptManager.GetCurrent(this) != null && ScriptManager.GetCurrent(this).IsInAsyncPostBack)
        {
            ScriptManager.RegisterStartupScript(rblStatus, typeof(RadioButtonList), Guid.NewGuid().ToString(), script, true);
        }
        else
        {
            ClientScript.RegisterStartupScript(typeof(RadioButtonList), Guid.NewGuid().ToString(), script, true);
        }

现在我的问题是在加载时我没有从单选按钮列表中选择单选按钮。

请帮忙我要解决这个问题。

Now my issue is while loading this i dont get focus on selected radio button from radio button list.
Please help me to solve this.

推荐答案

你应该把重点放在rblStatus而不是单个选定的列表项上。需要做这样的事情：

You should set focus on rblStatus and not on individual selected list item. Need to do something like this:

document.getElementById(''<%= rblStatus.ClientID %>'').focus();
