@Html.ActionLink("Preview", "Update", "Home", new { @report_id = Request.QueryString["report_id "] }, new { @class = "btn btn-info", target = "_blank" })

Pls help, Thanks

You need javascript to update the href attribute of the link based on the edited value in the textbox (or just enclose the textbox in a form with FormMethod.Get. And there is no point adding new { @report_id = Request.QueryString["report_id "] } - that's just adding the original value of report_id — user3559349

First give an ID attribute to the action link like below:

@Html.ActionLink("Preview", "Update", "Home", new { @report_id = Request.QueryString["report_id "] }, new { @class = "btn btn-info", target = "_blank", id="alink" })

Then write a jQuery click event function for the ActionLink:

$("#alink").click(function () {
    $(this).attr("href", $(this).attr("href") + "?id=" + $("#report_id").val());
});

See if it will work for you.

Hi @Faisal, follow you code, i can get textbox id. But I press "preview" button 2 times more, address link will general so much "report_id". see "/Reports/Home/Update?report_id=161024001?report_id=161024001?report_id=161024001".

In that case need to check if the id parameter already exists before adding it again. Something like: var url =$(this).attr("href"); if(url.indexOf('?report_id=') == -1) {$(this).attr("href", $(this).attr("href") + "?report_id=" + $("#report_id").val());}
