具有数据列的动态gridview

Question

i am using gridview control which having i Have to insert the gridview columns dynamic i insert a row values like

i Have to insert the gridview columns dynamic i insert a row values like

string[,] mularray = {
                      {"F_1","F_2","F_3","F_4","F_5","F_6"}
                     };

foreach (string names in mularray)
{
    for (int i = 0; i < 1; i++)
    {                   
        dt.Rows[dt.Rows.Count - 1]["10:00-11:00"] = mularray[i, 0];
        dt.Rows[dt.Rows.Count - 1]["11:00-12:00"] = mularray[i, 1];
        dt.Rows[dt.Rows.Count - 1]["12:00-01:00"] = mularray[i, 2]; 
        dt.Rows[dt.Rows.Count - 1]["02:00-03:00"] = mularray[i, 3];
        dt.Rows[dt.Rows.Count - 1]["03:00-04:00"] = mularray[i, 4];
        dt.Rows[dt.Rows.Count - 1]["04:00-05:00"] = mularray[i, 5];     
    }   
}

when i use this but it is inserting in last row like i shown in picture

next rows values should increment like F-2,F-3,F_4,F_5,F_6,F_1 then what have to do like this

If I am understanding you correctly, you should be able to do something as simple as the following:

string[,] mularray =
{
    {"F_1","F_2","F_3","F_4","F_5","F_6"},
    {"F_2","F_3","F_4","F_5","F_6","F_1"},
    {"F_3","F_4","F_5","F_6","F_1","F_2"},
    {"F_4","F_5","F_6","F_1","F_2","F_3"},
    {"F_5","F_6","F_1","F_2","F_3","F_4"},
    {"F_6","F_1","F_2","F_3","F_4","F_5"}
};

for (int i = 0; i < mularray.GetLength(0); i++)
{
    for (int j = 0; j < mularray.GetLength(1); j++)
    {
        dt.Rows[i]["10:00-11:00"] = mularray[j, 0];
        dt.Rows[i]["11:00-12:00"] = mularray[j, 1];
        dt.Rows[i]["12:00-01:00"] = mularray[j, 2];
        dt.Rows[i]["02:00-03:00"] = mularray[j, 3];
        dt.Rows[i]["03:00-04:00"] = mularray[j, 4];
        dt.Rows[i]["04:00-05:00"] = mularray[j, 5];
    }
}

This iterates through mularray in both dimensions. It assigns each row of mularray (defined by iterator i ) to DataTable dt . It uses your original loop (redefined with iterator j ) which assigns values to each of the cells within the current row.

As well, if you are only trying to input a single line and automatically shift elements to the right during each iteration, this can be simplified. You could use the modulo operator ( % ) to cause the elements to loop around, with an offset to select the correct value.

string[] mularray = { "F_1", "F_2", "F_3", "F_4", "F_5", "F_6" };

for (int i = 0; i < 6; i++)
{
        dt.Rows[i]["10:00-11:00"] = mularray[i];
        dt.Rows[i]["11:00-12:00"] = mularray[(i + 1) % 6];
        dt.Rows[i]["12:00-01:00"] = mularray[(i + 2) % 6];
        dt.Rows[i]["02:00-03:00"] = mularray[(i + 3) % 6];
        dt.Rows[i]["03:00-04:00"] = mularray[(i + 4) % 6];
        dt.Rows[i]["04:00-05:00"] = mularray[(i + 5) % 6];
}

In this case the mularray has been changed to a single dimension string array, because both dimensions are not necessary. Now the elements are selected by the calculated index, using (i + 1) % 6 to represent the pattern of {1, 2, 3, 4, 5, 0} . Likewise the next element can be selected by (i + 2) % 6 which represents {2, 3, 4, 5, 0, 1} . The first element does not require use of modulo because it uses i , which already represents {0, 1, 2, 3, 4, 5} .
