问题描述

嗨朋友们，

Hi friends,

protected void submitbtn_Click(object sender, EventArgs e)
        {
            classmarkgrid.Columns.Clear();
            comp.ACADAMICYEAR = acyeardropdown.SelectedItem.Text.ToString();
            comp.MEDIUM = mediumdropdown.SelectedItem.Text.ToString();
            string cname = classdropdown.SelectedItem.Text;
            string[] divide = cname.Split('-');
            comp.CLASSNAME = divide[0].ToString();
            comp.SECTIONNAME = Convert.ToChar(divide[1].Trim().ToString());
            comp.EXAMNAMES = examdropdown.SelectedItem.Text;
            DataSet getmark = inter.getclassmark(comp);
            if (getmark.Tables.Count >0)
            {
                if (comp.EXAMNAMES == "Quartely Exam" || comp.EXAMNAMES == "Half yearly exam" || comp.EXAMNAMES == "Annual Exam")
                {
                    DataTable bindtable = inter.bindtablesformarksingrid(getmark);
                    classmarkgrid.DataSource = bindtable;
                }
                else
                {
                    DataTable bindtable1 = inter.bindtablesformarkextergrid(getmark);
                    classmarkgrid.DataSource = bindtable1;
                    
                }
                 
                classmarkgrid.DataBind(); //problem in this databind method. Here row databound event is not fired.

            }
            else
            {
                DataTable studentlist = inter.getstudentlistformark(comp);

                DataTable gridback =mark.setgrid(studentlist, getsubjectforclass, comp);
                if (comp.EXAMNAMES == "Quartely Exam" || comp.EXAMNAMES == "Half yearly exam" || comp.EXAMNAMES == "Annual Exam")
                {

                    for (int i = 0; i < gridback.Columns.Count; i++)
                    {
                        
                        if (i >= 3)
                        {
                            TemplateField adtmep = new TemplateField();
                            adtmep.ShowHeader = true;
                            adtmep.HeaderText = gridback.Columns[i].ColumnName;
                            adtmep.ItemTemplate = new  gridviewtemplatewithoutbind(DataControlRowType.DataRow, gridback.Columns[i].ColumnName, gridback.Columns[i].ColumnName, "TextBox");
                            classmarkgrid.Columns.Add(adtmep);
                            continue;
                        }
                        TemplateField adtmep1 = new TemplateField();
                        adtmep1.ShowHeader = true;
                        adtmep1.HeaderText = gridback.Columns[i].ColumnName;
                        adtmep1.ItemTemplate = new gridviewtemplate(DataControlRowType.DataRow, gridback.Columns[i].ColumnName, gridback.Columns[i].ColumnName, "Label");
                        classmarkgrid.Columns.Add(adtmep1);


                        
                    }
                }
                else
                {
                    for (int i = 0; i < gridback.Columns.Count; i++)
                    {

                        if (i >= 3)
                        {
                            TemplateField adtmep = new TemplateField();
                            adtmep.ShowHeader = true;
                            adtmep.HeaderText = gridback.Columns[i].ColumnName;
                            adtmep.ItemTemplate = new gridviewtemplatewithoutbind(DataControlRowType.DataRow, gridback.Columns[i].ColumnName, gridback.Columns[i].ColumnName, "TextBox");
                            classmarkgrid.Columns.Add(adtmep);
                            continue;
                        }
                        
                        TemplateField adtmep1 = new TemplateField();
                        adtmep1.ShowHeader = true;
                        adtmep1.HeaderText = gridback.Columns[i].ColumnName;
                        adtmep1.ItemTemplate = new gridviewtemplate(DataControlRowType.DataRow, gridback.Columns[i].ColumnName, gridback.Columns[i].ColumnName, "Label");
                        classmarkgrid.Columns.Add(adtmep1);



                    }
                }
                

                classmarkgrid.DataSource = gridback;
                classmarkgrid.DataBind();// here it is fired
              //  ViewState["bindclassmark"] = gridback;
                
                Savebtn.Visible = true;
                Cancelbtn.Visible = true;
            }
            

        }

在此代码中，classgridview rowdatabound事件触发'else'条件。没关系。但是对于'if'条件rowdatabound事件没有被触发。

In this code classgridview rowdatabound event fires for the 'else' condition. its ok. but for' if' condition rowdatabound event not fired.

推荐答案

你可以通过注册onrowdatabound事件来解决数据行绑定事件的网格问题的唯一方法你的网格。



尝试做类似这个例子的事情。

The only way you can make the grid's on data row bound event to be fired is by registering the onrowdatabound event of your grid.

Try doing something like in this example.
