Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed - lena405690 - 07-23-2023 I have a grid view on my page and I want to export it to the Excel Sheet, Below is the code I had written to do this task, here I am already passing the dataset to the method to bind the grid and `btnExcelExport` is the button which will export the Grid Content in to Excel Sheet :- private void BindGridView(DataSet ds) { if (ds.Tables.Count > 0) { if (ds.Tables[0].Rows.Count > 0) { GVUserReport.DataSource = ds; GVUserReport.DataBind(); btnExcelExport.Visible = true; } } } protected void btnExcelExport_Click(object sender, EventArgs e) { Response.Clear(); Response.AddHeader("content-disposition","attachment;filename=FileName.xls"); Response.Charset = ""; Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.ContentType = "application/vnd.xls"; System.IO.StringWriter stringWrite = new System.IO.StringWriter(); System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite); GVUserReport.RenderControl(htmlWrite); Response.Write(stringWrite.ToString()); Response.End(); } public override void VerifyRenderingInServerForm(Control control) { return; } Now when I am debugging I found that the grid is binded sucessfully but when trying to export it to Excel, I'm getting this error: > "Microsoft JScript runtime error: > Sys.WebForms.PageRequestManagerParserErrorException: The message > received from the server could not be parsed." RE: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed - Mrbrand6 - 07-23-2023 I fixed this issue. As I'm using `UpdatePanel`, I added below code in the `Page_Load` event of the page and it worked for me: protected void Page_Load(object sender, EventArgs e) { ScriptManager scriptManager = ScriptManager.GetCurrent(this.Page); scriptManager.RegisterPostBackControl(this.btnExcelExport); //Further code goes here.... } RE: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed - dyestuffs685795 - 07-23-2023 I had the same error, then I tried **`<asp:PostBackTrigger ControlID="xyz"/>`** instead of **AsyncPostBackTrigger** .This worked for me. It is because we don't want a partial postback. RE: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed - nonstandardized559997 - 07-23-2023 1- **Never** use Response.Write. 2- I put the code below after create (not in Page_Load) a LinkButton (dynamically) and solved my problem: ScriptManager scriptManager = ScriptManager.GetCurrent(this.Page); scriptManager.RegisterPostBackControl(lblbtndoc1); RE: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed - albie319 - 07-23-2023 In my case, the problem was caused by some **Response.Write** commands at **Master Page** of the website (code behind). They were there only for debugging purposes (that's not the best way, I know)... RE: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed - accroides161856 - 07-23-2023 Add this to you PageLoad and it will solve your problem: ScriptManager scriptManager = ScriptManager.GetCurrent(this.Page); scriptManager.RegisterPostBackControl(this.lblbtndoc1); RE: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed - Sirmancini2 - 07-23-2023 [This][1] worked for me too, but with an addition (below). protected void Page_Load(object sender, EventArgs e) { ScriptManager scriptManager = ScriptManager.GetCurrent(this.Page); scriptManager.RegisterPostBackControl(this.btnExcelExport); //Further code goes here.... } I was registering a script on my button to click on another button after its event was finished processing. In order for it to work, I had to remove the other button from the Update Panel (just in case somebody faces the same problem).
