Create a table header in the Gridview, click the cell pop-up dialog box, and change the cell background color.

The complete code is on GitHub. Path:

Project Background: track an issue and record the daily status.

Requirements: 1. Click the date to change the status.

2. Add a button to disable issue.

3. layout requires that the date be placed after the tracking information

 

After receiving this short and competent requirement, I thought it was a bit confusing and I didn't have any sample images. The main requirement is a group of people who do not fully understand development. They are completely, completely, and completely ignorant !!! Miss the days of software companies ......

I thought about it, drew a sketch similar to the following, and wrote a Specification in detail according to the requirements. After the consistency is passed, I began to prepare for writing this function ....

Let's just look at the diagram and code ~

 

:

 

The front-end. aspx code is short and only one invisible ButtonField is bound for cell Click Event

Major background code snippets

Recreate the header in the event gvData_RowCreated.

 switch (e.Row.RowType)            {                   case DataControlRowType.Header:                    TableCellCollection tcHeader = e.Row.Cells;                    tcHeader.Clear();                    tcHeader.Add(new TableHeaderCell());                    tcHeader[0].Text = "xxxx";                    tcHeader.Add(new TableHeaderCell());                    tcHeader[1].Text = "xxxx";                    tcHeader.Add(new TableHeaderCell());                    tcHeader[2].Text = "xxxx";                    tcHeader.Add(new TableHeaderCell());                    tcHeader[3].Text = "xxxx";                    tcHeader.Add(new TableHeaderCell());                    tcHeader[4].Text = "xxxxx";                    tcHeader.Add(new TableHeaderCell());                    tcHeader[5].Text = "xxxxx";                    tcHeader.Add(new TableHeaderCell());                    tcHeader[6].Text = "xxxx.";                    tcHeader.Add(new TableHeaderCell());                    tcHeader[7].Text = "xxxxx";                    tcHeader.Add(new TableHeaderCell());                    tcHeader[8].Text = "xxxxx";                    tcHeader.Add(new TableHeaderCell());                    tcHeader[9].Text = "xxxxx";                    tcHeader.Add(new TableHeaderCell());                    tcHeader[10].Text = "Status";                    tcHeader.Add(new TableHeaderCell());                    tcHeader[11].Text = "Remarks";                    tcHeader.Add(new TableHeaderCell());                    tcHeader[12].Text = "Month";                    tcHeader.Add(new TableHeaderCell());                    tcHeader[13].Attributes.Add("colspan", "31");                    tcHeader[13].Text = "xxxx Data";                    break;            }

Click the Event code. First, you need to set the column from which you can click the pop-up box. Then, in the RowDataBound event, you can click and pop-up box.

  if (e.Row.RowType == DataControlRowType.DataRow)            {                LinkButton _singleClickButton = (LinkButton)e.Row.Cells[0].Controls[0];                string _jsSingle = ClientScript.GetPostBackClientHyperlink(_singleClickButton, "");                //add events to each editable cell                for (int columnIndex = _firstEditCellIndex; columnIndex < e.Row.Cells.Count; columnIndex++)                {                    //add the column index as the event argument parameter                    string js = _jsSingle.Insert(_jsSingle.Length - 2, columnIndex.ToString());                    e.Row.Cells[columnIndex].Attributes["onclick"] = js;                    e.Row.Cells[columnIndex].Attributes["style"] += "cursor:pointer;cursor:hand;";                    e.Row.Cells[columnIndex].Attributes.Add("onclick", "openWin('" + requestNo + "','" + month + "','" + date + "');");                                    }            }

Changing the cell background color is also in RowDataBound.

 if (date.Contains("P"))                        {                            date = date.TrimEnd('P');                            e.Row.Cells[columnIndex].BackColor = ColorTranslator.FromHtml("#525f6b");                        }                        if (date.Contains("Y"))                        {                            date = date.TrimEnd('Y');                            e.Row.Cells[columnIndex].BackColor = ColorTranslator.FromHtml("#fac970");                        }                        if (date.Contains("L"))                        {                            date = date.TrimEnd('L');                            e.Row.Cells[columnIndex].BackColor = ColorTranslator.FromHtml("#15a452");                        }                        if (date.Contains("R"))                        {                            date = date.TrimEnd('R');                            e.Row.Cells[columnIndex].BackColor = Color.Red;                        }                        if (date.Contains("B"))                        {                            date = date.TrimEnd('B');                            e.Row.Cells[columnIndex].BackColor = ColorTranslator.FromHtml("#004986");                        }                        e.Row.Cells[columnIndex].Text = date;

Set the Status column to click to close the column. The Code is as follows:

   string editJs = _jsSingle.Insert(_jsSingle.Length - 2, 11.ToString());   e.Row.Cells[11].Attributes["onclick"] = editJs;   e.Row.Cells[11].Attributes["style"] += "cursor:pointer;cursor:hand;";   if (e.Row.Cells[11].Text == "Ongoing")      e.Row.Cells[11].Text = "
The possible implementation method is not very good. Please advise more ~
