Custom Pagination In GridView With Formatting Using ASP.NET

Introduction

• Here, I will explain how to use custom pagination in GridView with formatting, using ASP.NET.
• Follow the steps mentioned below to achieve our requirement.

1. public string currentSelectedIndex = string.Empty;
2. public string totalPageCount = string.Empty;
3. public string UserEmail = string.Empty;
4. protected void Page_Load(object sender, EventArgs e)
5. {
6. if (!IsPostBack)
7. {
8. LoadData();
9. int currentIndex = Convert.ToInt32(Convert.ToString(GridActiveIndex.Value));
10. if (currentIndex > 0)
11. {
12. CustomGrid.PageIndex = currentIndex;
13. }
15. }
17. }
19. private void LoadData()
20. {
21. DataTable dt = new DataTable();
22. dt = getResultTable();
23. CustomGrid.DataSource = dt;
24. CustomGrid.DataBind();
25. GridActiveIndex.Value = '0″;
26. FotmatPager(0);
27. }
29. DataTable getResultTable()
30. {
31. DataTable dtproduct = new DataTable();
32. dtproduct.Columns.Add('ID', typeof(int));
33. dtproduct.Columns.Add('NAME', typeof(string));
34. dtproduct.Columns.Add('PRICE', typeof(int));
36. // Here we add five DataRows.
37. dtproduct.Rows.Add(1, 'Product1″, 100);
38. dtproduct.Rows.Add(2, 'Product2″, 110);
39. dtproduct.Rows.Add(3, 'Product3″, 120);
40. dtproduct.Rows.Add(4, 'Product4″, 130);
41. dtproduct.Rows.Add(5, 'Product5″, 140);
43. return dtproduct;
44. }
45. #region GridVariable
47. GridViewRow pagerRow;
48. int current_index;
49. int page_count;
51. #endregion
52. public string CurrentSelectedIndex
53. {
54. get { return currentSelectedIndex; }
55. set { currentSelectedIndex = value; }
56. }
57. public string TotalPageCount
58. {
59. get { return totalPageCount; }
60. set { totalPageCount = value; }
61. }
62. protected void formatTopPager(int current, int total)
63. {
64. try
65. {
66. pagerRow = CustomGrid.TopPagerRow;
67. Label lblcurrentindex =
68. (Label)pagerRow.Cells[0].FindControl('LabelCurrentIndex');
69. lblcurrentindex.Text = current.ToString();
70. Label lbllastindex =
71. (Label)pagerRow.Cells[0].FindControl('LabelLastIndex');
72. lbllastindex.Text = total.ToString();
73. CurrentSelectedIndex = current.ToString();
74. TotalPageCount = total.ToString();
75. }
76. catch (Exception)
77. {
79. //throw;
80. }
81. }
82. protected void fotmatBottomPager(int current, int total)
83. {
84. try
85. {
86. pagerRow = CustomGrid.BottomPagerRow;
87. Label lblcurrentindex =
88. (Label)pagerRow.Cells[0].FindControl('LabelCurrentIndex');
89. lblcurrentindex.Text = current.ToString();

93. CurrentSelectedIndex = current.ToString();
94. TotalPageCount = total.ToString();
95. }
96. catch (Exception)
97. {
99. // throw;
100. }
102. }
104. protected void FotmatPager(int current)
105. {
106. ViewState["currentPageIndex"] = current;
107. current += 1;
109. int total = CustomGrid.PageCount;
110. formatTopPager(current, total);
111. fotmatBottomPager(current, total);
112. CustomGrid.PageIndex = Convert.ToInt32(Convert.ToString(ViewState["currentPageIndex"]));
114. }
116. protected void ManageGridLayout(DataTable dt, int selected_pageIndex, int totalPage)
117. {
119. CustomGrid.PageIndex = selected_pageIndex;
120. CustomGrid.DataSource = getResultTable();
121. CustomGrid.DataBind();
122. FotmatPager(selected_pageIndex);
124. }
126. protected void ImageButtonNext_Click(object sender, ImageClickEventArgs e)
127. {
128. current_index = CustomGrid.PageIndex;
129. page_count = CustomGrid.PageCount;
130. if (current_index + 1 < page_count)
131. ManageGridLayout(getResultTable(), current_index + 1, page_count);
132. }
134. protected void ImageButtonPrev_Click(object sender, ImageClickEventArgs e)
135. {
136. current_index = CustomGrid.PageIndex;
137. page_count = CustomGrid.PageCount;
