DataGrid template column hyperlink column passing parameter problem summary (multiple parameter passing)

1. There is a small error. The general method is correct. Use a Java Script.

Navigateurl = "javascript: var win = Window. Open ('<% #" ksmd. aspx? Kcbh = "+ databinder. eval (container, "dataitem. course No. ") +" & ksrq = "+ databinder. eval (container, "dataitem. exam date ") %> ','', 'height = 250, width = 700, Top = 250, Left = 150, toolbar = No, menubar = No, crollbars = No, resizable = No, location = No, status = no ')"

The DataGrid's hyperlinkcolumn column is great to have a column with an hyperlink that points to an URL with a parameter whose value is taken from the data source, but what if you need to build the target URL with more than one parameter taken from the data source? In this case you can use a template column as follows:

<Templatecolumn>
<Itemtemplate>
<Asp: hyperlink runat = "server" navigateurl = '<% # "details. aspx? Employeeid = "& container. dataitem (" ID ") &" & employeename = "& container. dataitem (" firstname ") %> '/>
</Itemtemplate>
</Templatecolumn>

Instead of doing the String concatenation yourself you can use the buildurlwithquerystring function, which must be declared with public/protected visibility in the code-behind, as follows:

<Templatecolumn>
<Itemtemplate>
<Asp: hyperlink runat = "server" navigateurl = '<% #_
Buildurlwithquerystring ("details. aspx", "employeeid", container. dataitem ("ID"), "employeename", container. dataitem ("firstname") %> '/>
</Itemtemplate>
</Templatecolumn>

<Asp: templatecolumn headertext = "buy">
<Itemtemplate>
<Asp: hyperlink id = hyperlink1 runat = "server"
TEXT = '<% # databinder. eval (container, "dataitem. dinggou") %>'
Navigateurl = '<% # "../gouwu/gouwu_ls.aspx? Commoditytype = "&
Databinder. eval (container, "dataitem. commoditytype ")
& "& Commodityname =" & databinder. eval (container, "dataitem. commodityname") %> '/>
</Itemtemplate>
</ASP: templatecolumn>

<Asp: templatecolumn headertext = "topic name">
<Itemtemplate>
<Asp: hyperlink text = '<% # databinder. eval (container, "dataitem. ica_name") %> 'navigateurl =' <% # "newsdetail. aspx? Id = "+ databinder. eval (container, "dataitem. ica_id ") +" & name = "+ databinder. eval (container, "dataitem. ica_name ") %> 'runat =" server "/>
</Itemtemplate>
</ASP: templatecolumn>

4. href for fixed text display
<Asp: templatecolumn headertext = "title">
<Headerstyle width = "14%" type = "codeph" text = "/codeph"> <Itemtemplate>
<A href = content. aspx? Postid = (<% # databinder. eval (container. dataitem, "postid") %>) '> display </a>
</Itemtemplate>
</ASP: templatecolumn>

5. How can I bind more than one field to pass multiple parameters in the DataGrid hyperlink column (hyperlinkcolum?

A.
<Asp: hyperlinkcolumn datatextfield = "ffff" headertext = "fff" navigateurl = "A. aspx? X = <% # databinder. eval (container. dataitem, "field name 1") %> & s = <% # databinder. eval (container. dataitem, "field name 2") %> "> </ASP: hyperlinkcolumn

B.
Page. response. Redirect ("repair_fitting_edit.aspx? Repair_name = "+ mydatagrid. items [E. item. itemindex]. cells [0]. text + "& fitting_get_day =" + mydatagrid. items [E. item. itemindex]. cells [1]. text + "& fitting_no =" + mydatagrid. items [E. item. itemindex]. cells [2]. text );

C.

First, convert the DataGrid to the template column, and then fill in the following content in the "attributes"-> "binding"-> text of hyperlink in the template column:

Databinder. eval (container. dataitem, "field name 1") + databinder. eval (container. dataitem, "field name 2 ")

<%
String window;

Window = request. querystring ["window"];
%>

<Frame src = "left_tree_list_map.aspx? Dm_tree = 101 & window = <% = Window %> "name =" leftframe "scrolling =" Auto ">

 

7. All of the above are directly written in HTML on the page. This method is used to directly write the. CS file.

String connstr = @ "Integrated Security = sspi; user id = sa; initial catalog = northwind; Data Source = myserver \ netsdk ";

Sqlconnection CNN = new sqlconnection (connstr );

Sqldataadapter da = new sqldataadapter ("select * from employees", CNN );

Dataset DS = new dataset ();

Da. Fill (DS, "employees ");

Itemplate temp = page. loadtemplate ("webusercontrol1.ascx ");

Templatecolumn Tc = new templatecolumn ();

TC. headertext = "last name ";

TC. itemtemplate = temp;

Datagrid1.columns. Add (TC );

Datagrid1.datasource = Ds;

Datagrid1.datamember = "employees ";

Datagrid1.databind ();
