I am using asp.net with c# with Master Page. I was trying to create new div for each loop in the while to be able to make the designee as i want. Is there any way that i can do this Or is there any other way to do if from my aspx.cs only?
aspx.cs :
protected void Page_Load(object sender, EventArgs e)
{
while (Reader.Read())
{
Response.Write("<div id=test >");
Response.Write(Reader.GetString(3)+" ");
Response.Write(Reader.GetString(10) + "<br />");
Response.Write("<a href='Info.aspx?param=" + Reader.GetString(0) + "' target='_blank'>" + "More..." + "</a>");
Response.Write( "<br />");
Response.Write("");
Response.Write("</div>");
//TextBox1.Text = Reader.GetString(3);
//TextBox2.Text = Reader.GetString(10);
}
}
aspx :
<%# Page Title="" Language="C#" MasterPageFile="~/MainDesigne.Master" AutoEventWireup="true" CodeBehind="MobilePageRouteDoc.aspx.cs" Inherits="WebApplication2.MobilePageRoteDoc" %>

<div id="test">
</div>
</asp:Content>
You could assign your <div id="test"> attribute runat="server" like this:
<div runat="server" id="test">
Then you can access it in your code behind:
test.InnerHtml = "your html here";
So basically first create your html(the multiple divs) in a loop, then add it to the 'test' div. Also I'd suggest you keep id of every element you create in your loop unique and don't forget to add double quotes... id="test1", id="test2", Here is your modified code:
protected void Page_Load(object sender, EventArgs e)
{
string html = "";
int i = 0;
while (Reader.Read())
{
html+= "<div id=\"test" + i + "\">";
html+= Reader.GetString(3) + " ";
html+= Reader.GetString(10) + "<br />";
html+= "<a href='Info.aspx?param=" + Reader.GetString(0) + "' target='_blank'>" + "More..." + "</a>";
html+= "<br />";
html+= "</div>";
i++;
}
test.InnerHtml = html;
}
If you want to add <div> you may follow this using HtmlGenericControl which can generate html
HtmlGenericControl div = new HtmlGenericControl();
div.ID = "AnyDivID";
div.TagName = "div";
div.Attributes["class"] = "YourClassName";
div.InnerText = string.Format("Inner text= {0} ;", "YourInnerText");
form1.Controls.Add(div);

I am generating this tags (IT,Marketing....) dynamically(codebehind) from the sql using linq to sql.
And when you click on any of the the tabs it will show the gridview as per table created in database.
But the gridview binding is done during page_load event, so everything is generated during page_load, now when you click any of the blue tabs , it will show you pre-generated gridviews.
Now i want to generate or load gridviews when i clck on [+] sign of any of the tabs and not during the page load

If you use a Multiview control for your tab container then you should be able to bind your code to load the Gridview to the ActiveViewChanged event and change your ActiveViewIndex property for that Multiview when your users navigate between your tabs.
I'm trying to dynamically create images in a table but it seems like the UpdatePanel is not updating. I have the following code in my .aspx page.
<%# Page Language="C#" AutoEventWireup="true" CodeFile="ViewTile.aspx.cs" Inherits="ViewTile" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">

</head>
<body runat="server">
<form id="form1" runat="server">
<div>
<asp:Image ID="tileImg" runat="server"/>
<asp:ScriptManager ID="ScriptManager1" runat="server"/>
<table>
<asp:updatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:PlaceHolder runat="server" ID="placeholder1"/>
</ContentTemplate>
</asp:updatePanel>
</table>
</div>
</form>
</body>
</html>
And then this this the aspx.cs page.
TableRow imageRow = new TableRow();
for (int rowItr = 0; rowItr < 3; rowItr++)
{
for (int colItr = 0; colItr < 4; colItr++)
{
System.Web.UI.WebControls.Image image = new System.Web.UI.WebControls.Image();
image.ImageUrl = "~/ShowTile.ashx?SheetId=" + SheetGUID + "&Scale=" + 3
+ "&XCoord=" + colItr + "&YCoord=" + rowItr;
placeholder1.Controls.Add(image);
TableCell imageCell = new TableCell();
imageCell.Controls.Add(image);
imageRow.Cells.Add(imageCell);
}
placeholder1.Controls.Add(imageRow);
imageRow.Cells.Clear();
}
I know for a fact that the image is being called correctly as I've outputted it manually using an image tag on the client. Any help would be great! Thanks
You need to add Table first, add rows to it and finally add table to placeholder1.Controls
Table tbl= new Table();
for (int rowItr = 0; rowItr < 3; rowItr++)
{
TableRow imageRow = new TableRow();
for (int colItr = 0; colItr < 4; colItr++)
{
System.Web.UI.WebControls.Image image = new System.Web.UI.WebControls.Image();
image.ImageUrl = "~/ShowTile.ashx?SheetId=" + SheetGUID + "&Scale=" + 3
+ "&XCoord=" + colItr + "&YCoord=" + rowItr;
TableCell imageCell = new TableCell();
imageRow.Cells.Add(imageCell);
}
tbl.Rows.Add(imageRow);
}
placeholder1.Controls.Add(tbl);
You Can Do this using javascript and Web Service.
Create a function that Call Web Service and fetch url of the image and append it into the update panel div
in my code i want to set a tag with values from a .mdb database (oleDb) and when the user registers as an administrator i add the contentEditable=true attribute to the parts i want him to be able to edit. when he is done he will hit a 'save' button and the code behind will update the new value into the database.
here is the code: (Admin.LogIn(,); also returns true if the user registered as an admin)

Problem is i am getting values in lblTableValues in js.But in code behid it does not contain any values its value is "".Can anybody help to get the value contained in hdnTableValues in click event in code behind.
You can use a hidden input with runat="server" to handle this. Store the value to the hidden field in JavaScript. And you can access the field value in C# code behind.
HTML
<input type="hidden" id="txtHidData" runat="server" />
JavaScript
document.getElementById ( "txtHidData" ).value = "your value";
C#
string valueInCodeBehind = txtHidData.Value;
Use the asp:HiddenField control like this: (jquery example)
in the page or control:
<asp:HiddenField ID="Hidden1" runat="server" Value="blank" />
<asp:PlaceHolder runat="server">
<script type ="text/javascript">
$(function () {
//get the id of the hidden control
var clientID = "<%= Hidden1.ClientID %>";
$("#" + clientID).val("this is from the client");
});
</script>
</asp:PlaceHolder>
In a button or submit method in code behind:
Debug.WriteLine("val: " + Hidden1.Value);
