如何在asp.net中为gridview动态添加列宽 [英] How to add the column width dynamically for gridview in asp.net

问题描述

朋友们，我对gridview有一个要求，我有一个数据表，我手动分配列名，并将数据添加到datatable。之后我垂直设置数据表并绑定到gridview。

Hi friends , I have a requirement on gridview, i have a datatable for that i was assigning the column names manually and also adding the data to datatable. After that i am set the datatable vertically and bind to the gridview.

var tbl = dt;


          var swappedTable = new DataTable();
          if (tbl.Rows.Count > 0)
          {
              swappedTable.Columns.Add("Name");

              for (int i = 0; i <= tbl.Rows.Count-1; i++)
              {


                  DataRow dx = tbl.Rows[i];


                  var x = dx.ItemArray;

                 // swappedTable.Columns.Add("Value"+i.ToString());



                  swappedTable.Columns.Add(x[3].ToString());



              }
              for (int col = 0; col < tbl.Columns.Count; col++)
              {
                  var r = swappedTable.NewRow();
                  r[0] = tbl.Columns[col].ToString();
                  for (int j = 1; j <= tbl.Rows.Count; j++)
                      r[j] = tbl.Rows[j - 1][col];


                  swappedTable.Rows.Add(r);
              }
              //dataGridView1.DataSource = swappedTable;

              gvwHDMonitor.DataSource = swappedTable;
              gvwHDMonitor.DataBind();

示例：





姓名 ...................... IICSS21



操作系统............. Microsoft Windows 7专业版

版本.. ............ 6.1.7601

制造商.............微软公司

计算机名称。 ............ IICSS21

Windows目录............. C：\ Windows

Serial编号............. 00371-OEM-9203635-37779

ComputerManufacturer名称.............戴尔公司
计算机型号............. OptiPlex 990

系统类型............... x64-based $





这里：Operationg系统，这些版本是列

Microsoft Windows 7 Professional，6.1.760l这些是数据表中的第一行，同时其他记录也动态添加到数据表中作为列。







这里动态地将列添加到datatable。

问题是我想增加动态添加列的列宽。

如何解决这个问题。



请任何人帮助我。

Example :


Name ...................... IICSS21

Operating System ............. Microsoft Windows 7 Professional
Version .............. 6.1.7601
Manufacturer ............. Microsoft Corporation
Computer Name ............. IICSS21
Windows Directory ............. C:\Windows
Serial Number ............. 00371-OEM-9203635-37779
ComputerManufacturer Name ............. Dell Inc.
Computer Model ............. OptiPlex 990
System Type ............. x64-based PC


here : Operationg system, Version like these are the columns
Microsoft Windows 7 Professional,6.1.760l these are the first row in datatable and same time other records also added dynamically to datatable as columns.



Here dynamically added the columns to datatable.
Problem is i want to increase the column width for dynamically added columns.
How can do this problem.

Please any one help me.

您好，



从以下代码中获取知识：

Hi,

Take knowledge from this below code :

protected void GridView1_RowDataBound(object sender,
    GridViewRowEventArgs e)
{
    System.Data.DataRowView drv;
    drv = (System.Data.DataRowView)e.Row.DataItem;
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
      if (drv != null)
      {
        String catName = drv[1].ToString();
        Response.Write(catName + "/");

        int catNameLen = catName.Length;
        if (catNameLen > widestData)
        {
          widestData = catNameLen;
          GridView1.Columns[2].ItemStyle.Width =
            widestData * 30;
          GridView1.Columns[2].ItemStyle.Wrap = false;
        }

      }
    }
}
