Editor to share with you how asp.net to achieve Gridview paging save options, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

The code is as follows:

# region / / 'Revision: 1.00 Created Date: 2013-08-02 Created ID: Una [# 1300071] add multiple option boxes

/ / /

/ / Session "take many" box value

/ / /

Private void RememberOldValues ()

{

ArrayList categoryIDList = new ArrayList ()

String index = ""

Foreach (GridViewRow row in gridView.Rows)

{

Index = (string) gridView.DataKeys [row.RowIndex] .value

Bool result = ((CheckBox) row.FindControl ("DeleteThis")) .Checked

/ / Check in the Session

If (Session ["id"]! = null)

CategoryIDList = (ArrayList) Session ["id"]

If (result)

{

If (! categoryIDList.Contains (index))

CategoryIDList.Add (index)

}

Else

CategoryIDList.Remove (index)

}

If (categoryIDList! = null & & categoryIDList.Count > 0)

Session ["id"] = categoryIDList

}

/ / /

/ / before Session, the multi-frame is true.

/ / /

Private void RePopulateValues ()

{

ArrayList categoryIDList = (ArrayList) Session ["id"]

If (categoryIDList! = null & & categoryIDList.Count > 0)

{

Foreach (GridViewRow row in gridView.Rows)

{

String index = (string) gridView.DataKeys [row.RowIndex] .value

If (categoryIDList.Contains (index))

{

CheckBox myCheckBox = (CheckBox) row.FindControl ("DeleteThis")

MyCheckBox.Checked = true

}

}

}

}

# endregion

The copy code is as follows:

Protected void gridView_PageIndexChanging (object sender, GridViewPageEventArgs e)

{

RememberOldValues ()

GridView.PageIndex = e.NewPageIndex

BindData ()

RePopulateValues ()

}

The copy code is as follows:

Protected void btnSelect_Click (object sender, EventArgs e)

{

String items = ""

ArrayList categoryIDList = new ArrayList ()

String index = ""

Foreach (GridViewRow row in gridView.Rows)

{

Index = (string) gridView.DataKeys [row.RowIndex] .value

Bool result = ((CheckBox) row.FindControl ("DeleteThis")) .Checked

/ / Check in the Session

If (Session ["id"]! = null)

CategoryIDList = (ArrayList) Session ["id"]

If (result)

{

If (! categoryIDList.Contains (index))

CategoryIDList.Add (index)

}

Else

CategoryIDList.Remove (index)

}

If (categoryIDList! = null & & categoryIDList.Count > 0)

For (int I = 0; I < categoryIDList.Count; iTunes +)

{

Items + = categoryIDList [I] + ","

}

Items = items.Substring (0, items.Length-1)

ScriptManager.RegisterStartupScript (this, this.GetType (), "," check ('"+ items +"'); ", true)

Session.Remove ("id")

}
