如何检索2个以上的值并将其放在gridview的文本框中 [英] how to retrieve more than 2 values and put it in textbox in gridview

问题描述

  int  rowIndex =  0 ; 
  for （ int  i =  1 ; i <  = dt.Tables [ 1 ]。Rows.Count; i ++）
 {
 System.Web.UI.WebControls.TextBox combobox =（System.Web.UI.WebControls.TextBox）gvmonoprixmasters.Rows [rowIndex] .Cells [ 0 ].FindControl(  combo）; 
 System.Web.UI.WebControls.TextBox sizes =（System.Web.UI.WebControls.TextBox）gvmonoprixmasters.Rows [rowIndex] .Cells [ 1  ] .FindControl（  sizes）; 
 System.Web.UI.WebControls.TextBox barcodenumber =（System.Web.UI.WebControls.TextBox）gvmonoprixmasters.Rows [rowIndex] .Cells [ 2  ] .FindControl（  barcodeno）; 
 System.Web.UI.WebControls.TextBox ratio =（System.Web.UI.WebControls.TextBox）gvmonoprixmasters.Rows [rowIndex] .Cells [ 3  ] .FindControl（  ratio）; 
 System.Web.UI.WebControls.TextBox qty =（System.Web.UI.WebControls.TextBox）gvmonoprixmasters.Rows [rowIndex] .Cells [ 4  ] .FindControl（  qty）; 
 combobox.Text = dt.Tables [ 1 ]。行[i  -   1 ] [   Combo1]。ToString（）; 
 sizes.Text = dt.Tables [ 1 ]。行[i  -   1 ] [  尺寸]。ToString（）; 
 barcodenumber.Text = dt.Tables [ 1 ]。行[i  -   1 ] [   Barcode_Number]。ToString（）; 
 ratio.Text = dt.Tables [ 1 ]。行[i  -   1 ] [   Ratio]。ToString（）; 
 qty.Text = dt.Tables [ 1 ]。行[i  -   1 ] [  数量]。ToString（）; 
 rowIndex ++; 
} 

我在第一次执行循环时得到所有值（rowIndex = 0）并且抛出错误虽然我增加了rowIndex，但索引超出了范围。 dt.Rows.Count = 3。

如何检索gridview中相应文本框中的所有3个值....

解决方案

我解决了自己......工作正常现在......

 受保护  void  LoadGridViewfromDB（）
 {
  try  
 {
 DataTable dtCurrentTable =（DataTable） ViewState [  CurrentTable]; 
  if （ViewState [  CurrentTable]！=  null ）
 {
 DataTable dt =  new  DataTable （）; 
 DataRow dr =  null ; 
 
 dt.Columns.Add（ new  DataColumn（  Col1， typeof （ string ）））; 
 dt.Columns.Add（ new  DataColumn（  Col2， typeof （ string ）））; 
 dt.Columns.Add（ new  DataColumn（  Col3， typeof （ string ）））; 
 dt.Columns.Add（ new  DataColumn（  Col4， typeof （ string ）））; 
 dt.Columns.Add（ new  DataColumn（  Col5， typeof （ string ）））; 
  for （ int  i =  1 ; i <  = dtCurrentTable.Rows.Count; i ++）
 {
 dr = dt.NewRow（）; 
 dr [  Col1] =  string  .Empty; 
 dr [  Col2] =  string  .Empty; 
 dr [  Col3] =  string  .Empty; 
 dr [  Col4] =  string  .Empty; 
 dr [  Col5] =  string  .Empty; 
 dt.Rows.Add（dr）; 
} 
 ViewState [  CurrentTable] = dt; 
 gvmonoprixmasters.DataSource = dt; 
 gvmonoprixmasters.DataBind（）; 
} 
  else  
 {
 Response.Write（  ViewState为null）; 
} 
} 
  catch （例外ee）{} 
} 

int rowIndex = 0;
                for (int i = 1; i <= dt.Tables[1].Rows.Count; i++)
                {
                    System.Web.UI.WebControls.TextBox combobox = (System.Web.UI.WebControls.TextBox)gvmonoprixmasters.Rows[rowIndex].Cells[0].FindControl("combo");
                    System.Web.UI.WebControls.TextBox sizes = (System.Web.UI.WebControls.TextBox)gvmonoprixmasters.Rows[rowIndex].Cells[1].FindControl("sizes");
                    System.Web.UI.WebControls.TextBox barcodenumber = (System.Web.UI.WebControls.TextBox)gvmonoprixmasters.Rows[rowIndex].Cells[2].FindControl("barcodeno");
                    System.Web.UI.WebControls.TextBox ratio = (System.Web.UI.WebControls.TextBox)gvmonoprixmasters.Rows[rowIndex].Cells[3].FindControl("ratio");
                    System.Web.UI.WebControls.TextBox qty = (System.Web.UI.WebControls.TextBox)gvmonoprixmasters.Rows[rowIndex].Cells[4].FindControl("qty");
                    combobox.Text = dt.Tables[1].Rows[i - 1]["Combo1"].ToString();
                    sizes.Text = dt.Tables[1].Rows[i - 1]["Sizes"].ToString();
                    barcodenumber.Text = dt.Tables[1].Rows[i - 1]["Barcode_Number"].ToString();
                    ratio.Text = dt.Tables[1].Rows[i - 1]["Ratio"].ToString();
                    qty.Text = dt.Tables[1].Rows[i - 1]["Quantity"].ToString();
                    rowIndex++;
                }

I get all the values when the loop executes 1st time(rowIndex=0) and throws error index was out of range though I increment the rowIndex. dt.Rows.Count=3.
How to retrieve all 3 values in respective textbox present in gridview....

解决方案

I solved myself ... Its working fine now...

protected void LoadGridViewfromDB()
    {
        try
        {
            DataTable dtCurrentTable =(DataTable)ViewState["CurrentTable"];
            if (ViewState["CurrentTable"] != null)
            {
                DataTable dt = new DataTable();
                DataRow dr = null;
                
                    dt.Columns.Add(new DataColumn("Col1", typeof(string)));
                    dt.Columns.Add(new DataColumn("Col2", typeof(string)));
                    dt.Columns.Add(new DataColumn("Col3", typeof(string)));
                    dt.Columns.Add(new DataColumn("Col4", typeof(string)));
                    dt.Columns.Add(new DataColumn("Col5", typeof(string)));
                    for (int i = 1; i <= dtCurrentTable.Rows.Count; i++)
                    {
                    dr = dt.NewRow();
                    dr["Col1"] = string.Empty;
                    dr["Col2"] = string.Empty;
                    dr["Col3"] = string.Empty;
                    dr["Col4"] = string.Empty;
                    dr["Col5"] = string.Empty;
                    dt.Rows.Add(dr);
                }
                ViewState["CurrentTable"] = dt;
                gvmonoprixmasters.DataSource = dt;
                gvmonoprixmasters.DataBind();
            }
            else
            {
                Response.Write("ViewState is null");
            }
        }
        catch (Exception ee) { }
    }
