Forms Data Controls :: Put A Click Button To Pass The Id Of The Photo To The Other Page?
Jul 31, 2010
I'm making a phot album for my family websit I'v gotten almost every thing down except the display. I have gotten the pictures to display as thumbnails using a datalist (because I can get the layout how I want it) However I wanted to put a click button to pass the id of the photo to the other page.So this is my question is their any way to pass the id from in a datalist to another page.this is the code i'm tryin to use now
I have passed the value from one page to next page using a querystring. In the next page i need to get the value from the query string and based on the value, it needs to checked with the database and the result set should be placed in the gridview, details view or listview anything else.

In the details view or list view control, I need to get the value vicky from the url and based on the value's row in the database table need to be binded in any of the mentioned above controls.
I have a datalist and the following link button within the datalist:
[Code]....
I would like to post to a new page and then capture the value from the link button (commandArgument). It appears from other threads I've seen that you have to rebind the datalist in order for the ItemCommand event to fire...is this true? I'd hate to make another DB call to bind my datalist just to make an event fire.
When image button(+) is pressed the selected row of gridview1 is shifted to 2nd gridview.And in the 2nd gridview there is also a imagebutton(delete),when the delete button is pressed that row will move to 1st gridview.
I have a small problem I am returning some data from a query and have allowed paging, however when I click on the next button to view the following page the gridview disappears.
My datasource is specified in the code behind:
<asp:Panel ID="dtpanel" runat="server" Visible="False"> <asp:GridView ID="grddetails" runat="server" AutoGenerateColumns="False" AllowPaging="True" OnPageIndexChanging="grddetails_SelectedIndexChanged" ViewStateMode="Enabled" onselectedindexchanged="grddetails_SelectedIndexChanged" AllowSorting="True" > <Columns> <asp:BoundField DataField="Col1" HeaderText="Col1" SortExpression="Col1" /> <asp:BoundField DataField="Col2" HeaderText="Col2" SortExpression="Col2" /> <asp:BoundField DataField="Col3" HeaderText="Col3" SortExpression="Col3" /> <asp:BoundField DataField="Col4" HeaderText="Col4" SortExpression="Col4" /> <asp:BoundField DataField="Col5" HeaderText="Col5" SortExpression="Col5" /> <asp:BoundField DataField="Col6" HeaderText="Col6" SortExpression="Col6" /> </Columns> </asp:GridView> </asp:Panel> using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Data; using System.Data.SqlClient; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void GridView2_SelectedIndexChanged(object sender, GridViewCommandEventArgs e) { int y = Convert.ToInt32(e.CommandArgument); Control control = GridView2.Rows[y].Cells[0].Controls[0]; LinkButton btn = control as LinkButton; string qval = btn.Text; string query = "SELECT * FROM Table WHERE Col LIKE '%" + qval + "%'"; string connectionString = @"Data Source=servername;Initial Catalog=dbname;Integrated Security=True"; SqlConnection accessConnection = new SqlConnection(connectionString); SqlCommand accessCommand = new SqlCommand(query, accessConnection); SqlDataAdapter grddetailsDataAdapter = new SqlDataAdapter(accessCommand); DataTable grddetailsDataTable = new DataTable("Table"); grddetailsDataAdapter.Fill(grddetailsDataTable); int dataTableRowCount = grddetailsDataTable.Rows.Count; if (dataTableRowCount > 0) { grddetails.DataSource = grddetailsDataTable; grddetails.DataBind(); } dtpanel.Visible = true; } protected void GridView1_SelectedIndexChanged(object sender, GridViewCommandEventArgs e) { int w = Convert.ToInt32(e.CommandArgument); Control control = GridView1.Rows[w].Cells[0].Controls[0]; LinkButton btn = control as LinkButton; string qval2 = btn.Text; Label1.Text = btn.Text; string query = "SELECT * FROM Table WHERE Col LIKE '%" + qval2 + "%'"; string connectionString = @"Data Source=servername;Initial Catalog=dbname;Integrated Security=True"; SqlConnection accessConnection = new SqlConnection(connectionString); SqlCommand accessCommand = new SqlCommand(query, accessConnection); SqlDataAdapter grddetailsDataAdapter = new SqlDataAdapter(accessCommand); DataTable grddetailsDataTable = new DataTable("Table"); grddetailsDataAdapter.Fill(grddetailsDataTable); grddetails.DataSource = grddetailsDataTable; grddetails.DataBind(); dtpanel.Visible = true; } protected void grddetails_SelectedIndexChanged(object sender, GridViewPageEventArgs e) { DataTable dataTable = grddetails.DataSource as DataTable; grddetails.PageIndex = e.NewPageIndex; grddetails.DataBind(); dtpanel.Visible = true; } }

on my default.aspx page, i have one dropdownlist (which has book types as values e.g. small books, medium books etc.). Then one textbox. And one button named 'Search'. On button click the datagrid shows result by filtering table data with book type and search string that user enter in textbox.
So on 'Search' button click, i want to load the same page with result but with query string like 'Default.aspx?booktype=small' (using response.redirect) if user selects small in dropdown list. The problem is when i click 'Search' button and the page gets loaded again I cannot access dropdownlist values and search string that user has entered. It takes null only when I use,
I have a databound repeater and in this repeater is an imageButton. How do I pass info from the database into the click event? For example, I've got the description, heading and price fields populating labels, but want the id to go into the imagebuttons click event in order to build a querystring.
I have little strange question. I would like to Validate my Page Controls on the button click which is there in the User Control. This user control is placed on the Page.

It will not save the information and it won't give the validation message too.
