[解决]如何从Gridview数据控制CheckboxList。 [英] [Solved] How to Control CheckboxList from Gridview Data.

问题描述

嗨开发者，



我面临以下问题：将gridview某些列数据与checkboxlist项目文本进行比较。



我有一个只有6个项目的复选框。

A

B

C

D

E

F



当从数据库和第3列填充gridview时，即：Cell [2] .Text具有字符串值A，B，C，D，E或F.每当它被填充时，我必须禁用该复选框列表中具有相同值的项目，如gridview cell [2]。



例如，如果我在Gridview单元格[2]中有A，C，E，F，那么Checkboxlist项目A，C，E，F应为enable = false ;



因为我为Page.Load事件创建了以下方法。

Hi Developers,

I am facing the following issue regarding comparing my gridview certain column data with checkboxlist item text.

I have a checkboxlist which has only 6 items.
A
B
C
D
E
F

When the gridview is populated from database and the 3rd column i-e: Cell[2].Text has the string values of A, B, C, D, E or F. Whenever it is being populated I have to disable the items of that checkboxlist which has same values like gridview cell[2].

For example if I have A, C, E, F in Gridview cell[2] then the Checkboxlist item A, C, E, F should be enable = false;

as I have created the following method for Page.Load Event.

private void EditMode()
    {
        foreach(GridViewRow gvRow in GridView3.Rows)
        {
            Label userID = gvRow.Cells[2].FindControl("Label4") as Label;

            for (int k = 0; k < CheckBoxList1.Items.Count; k++)
            {
                if (CheckBoxList1.Items[k].Text == userID.Text)
                {
                    CheckBoxList1.Items[k].Enabled = false;
                }
            }
        }
    }

请帮助..：）

Please Help.. :)

推荐答案

protected void GridView3_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowState != DataControlRowState.Edit) // check for RowState
        {
            if (e.Row.RowType == DataControlRowType.DataRow) //check for RowType
            {

                foreach (ListItem c in CheckBoxList1.Items)
                {
                    if (c.Text == userID.Text)
                    {
                        c.Enabled = false;
                    }
                }
            }
       }
    }

和保留复选框状态，无论是否已选中

and to retain the checkboxes statuses whether checked or not

protected void GridView3_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        DataTable dt2 = ViewState["DatainEditMode"] as DataTable;
        int index = Convert.ToInt32(e.RowIndex);
        if (dt2.Rows[index][2].ToString() == CheckBoxList1.Items[0].Text.ToString())
        {
            CheckBoxList1.Items[0].Enabled = true;
        }
        else if (dt2.Rows[index][2].ToString() == CheckBoxList1.Items[1].Text.ToString())
        {
            CheckBoxList1.Items[1].Enabled = true;
        }
        else if (dt2.Rows[index][2].ToString() == CheckBoxList1.Items[2].Text.ToString())
        {
            CheckBoxList1.Items[2].Enabled = true;
        }
        else if (dt2.Rows[index][2].ToString() == CheckBoxList1.Items[3].Text.ToString())
        {
            CheckBoxList1.Items[3].Enabled = true;
        }
        else if (dt2.Rows[index][2].ToString() == CheckBoxList1.Items[4].Text.ToString())
        {
            CheckBoxList1.Items[4].Enabled = true;
        }
        else if (dt2.Rows[index][2].ToString() == CheckBoxList1.Items[5].Text.ToString())
        {
            CheckBoxList1.Items[5].Enabled = true;
        }
        dt2.Rows[index].Delete();
        string task_no = ((Label)GridView3.Rows[e.RowIndex].FindControl("LBL_TASKNO")).Text;
        tskctrl.deleteTaskNoDetail(task_no);
        GV3DataBinding(lbl_pTask.Text.ToString());
    }
