Gridview cross page data transfer

[srishree]

I have a gridview with a link in the parent page.when i click on the link it opens up another gridview.this child gridview has 2 columns,one is a checkbox created using an itemtemplate and another a boundfield retreiving data from the database.what i want is when i check the checkbox of a particular row and hit a button,the data existing in that particular row of the child gridview which has been checked,has to transfer the data from that row to the parent gridview,in a sense the parent gridview has to refresh and show up with the new data that has come from the child gridview control.How can i do this?..........urgent..........

If you want to use pop up window for child gridview, write window.open ("popupwindowname.aspx","mywindow","toolbar=no,scrollbars=yes,resizable=yes,menubar=0,width=700,height=520"); in Parent window design page. And write Session("var1") = gvChild.SelectedDataKey.Value.ToString() Dim scriptSubmit As String = " window.opener.document.forms(0).submit(); " If Not Page.ClientScript.IsClientScriptBlockRegistered(scriptSubmit) Then Page.ClientScript.RegisterClientScriptBlock(Me.GetType(), "script", scriptString) End If Dim ScriptClose As String = " window.close();" Page.ClientScript.RegisterClientScriptBlock(Me.GetType, "Close", ScriptClose) In popup window button click. It will refresh the parent page. In the pageload, with the help of session(“var1”), you can load the new data in the parent gridview. -Priya

Sure… Hope you understand that window.open(…..); should be written in javascript function which will be called when the user clicks the link of the parent gridview. And in child window , I think, it is better to add an auto generated select button instead of a checkbox, if that doesn’t serve for a special purpose other than to indicate the desired row. Because, it may be ambiguous, if you check multiple checkboxes at a time. If you add select button, the user can select the desired row and click the button. In button click, //assign the primary key value of the selected row into a session variable //For this, you should have assigned the primary key field to the DataKeyNames property //in the design mode(or at codebehind) of the gridview Session(“var1”)=gvChild. SelectedDataKey.Value.ToString(); String scriptSubmit== " window.opener.document.forms(0).submit(); "; If(!Page.ClientScript.IsClientScriptBlockRegistered(scriptSubmit)) Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "script", scriptString); string ScriptClose = " window.close();"; Page.ClientScript.RegisterClientScriptBlock(this.GetType, "Close", ScriptClose); In parent window page load, if(Session(“var1”)!=””) { //do the required using this session variable since this holds the primary key value of the record // I’ve not written the code because I’m not aware of your exact requirement whether insertion or modification) Session(“var1”)=””; 00000//better to clear the session even in the Session_End event of global.asax } Hope this may help you. You are welcome, if you have any queries regarding this. -Vishnu Priya
