Actually i am using below code to open new tab

OnClientClick="var originalTarget = document.forms[0].target; document.forms[0].target = '_blank'; setTimeout(function () { document.forms[0].target = originalTarget; }, 3000);"

the above code is using while clicking on the link button in that linkbutton i am redirecting to one file like pdf,xml

here my problem is if the file is there means it is opening correctly only but if the file is not there means it is opening same page from where i am clicking so i desided to do from code behind

is there any possibility to do like that

If the file is there you show the file in a new tab, but if it is not there what is the logic for this you have?

ntitish 17-Oct-14 6:45am

Nothing . for now i am not opening the new tab.

you mean even if the file exists it is not opening in a new tab?

ntitish 17-Oct-14 6:52am

Solution 1

try this
you can do this like by adding attribute in anchor here I have anchor that you can use link button
var url = "abc.aspx";
anchor.Attributes.Add("target", "_blank");
anchor.Attributes.Add("href", "" + url + "");

sorry for not explaining my issue clearly. Actually from database i am binding documents to gridview with different types of documents like (.pdf,.xml,.txt,.doc... etc)
now i want to open the files in new tab after clicking the document view button. here i ac heaved opening in new window. but i want to open in new tab from where i am seeing the documents grid. the path will be dynamically given in code behind.

ntitish 18-Oct-14 3:39am

Thanks i solved by using your concept in different manner.

while binding to the grid itself i added these atributes if the path is not found i am not binding these attributes

ntitish 17-Oct-14 7:59am

In that link there are 5 solutions. which solution are you saying

[no name] 17-Oct-14 8:33am

ClientScript.RegisterStartupScript(this.Page.GetType(), "",
"window.open('somepage.aspx','Graph','height=400,width=500');", true);
The code project solution. Window.Open() will let you open in new tab itself. :)
