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