In my gridview I am selecting data using search textbox....
I want to make pdf file of the searched data....
but when I clicked on my pdfbutton after searching data it make the pdf file of all data present in my table....
I m doing a project to export the data from Gridview to PDF. Everything was fine and a new pdf document has been opened whenever I click the PDF image but there was no records displayed in it.
I have 15 records in Gridview and those records have displayed using Table Adapter. I used the Sand and Sky Auto Formatting option in Gridview and color, tablecell width, 15 rows are displayed perfectly in PDF without the text. what am I missing.

using System.Collections;

Before converting a gridview to PDF I can modify the font size and color using:
gridview.HeaderRow.Style.Add("font-family","Arial, Helvetica, sans-serif;"); gridview.HeaderRow.Style.Add("font-size","7.20px"); gridview.HeaderRow.Style.Add("color","#284775");
gridview.Style.Add("font-family","Arial, Helvetica, sans-serif;");
gridview.Style.Add("font-size","6px");
The gridview has different column widths because of the information that is being displayed, those sizes are set .aspx file. But, the generated pdf file auto adjusts the width of each column to be the same size, therefore the information is shrinked and doesnt look good..
I tried the following:
gridview.Width =100;
or
gridview.Style.Add("width","100");
or
gridview.Columns[3].ItemStyle.Width =Unit.Pixel(10);
And many more but haven't been able to adjust the gridview to it's original columns width. How can I do that?
This is the code I use to generate the PDF file:
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=UserDetails.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);

I am using ITextSharp to create a pdf. But when I am binding data to Gridview dynamically which was actually a result of ajax webmethod, its showing a blank PDF file. So how can I export dynamically binded data to GridView to PDF. Is there any other way to export dynamically binded gridview data to PDF?

View 1 RepliesI'm trying to export my gridview to pdf but the html parsing of the iTextSharp control seems to be failing. I have to create an HtmlForm like below and add the gridview to it because the code is in a custom control, so I cant pass the gridview directly. I get an error saying "gridview must be in a form tag with runat=server"
If I don't insert the test header like i do below, I get an error saying "document has no pages"
At the moment the pdf is generated but it only has the text "testing".
The htmlform html doesn't get parsed i think. Here is a small portion of what the newHtml variable below contains when I create it.

I would like a gridview (using entitydatasource) to display the search results based on values provided in textbox txtSearch and dropdownlist ddlsearch. My search controls are as follows:
[Code]....
My entitydatasource is:
[Code]....
My gridview is written as:
[Code]....
Codebehind file contains:
[Code]....
I am a newbie at entitydatasource and have a few questions:
1. Currently, the gridview doesn't render. Why is that?
2. How do I wire up the gridview to grab the values of ddlsearch and txtSearch and return results using those values from my entitydatasource?
3. Ultimately, I want to encapsulate this gridview in a wizard step wherein the user checks items they want and those checked items are used in the next wizard step.
I am using textsharp dll to export to pdf.Its exporting the gridview without the header row.
View 1 RepliesI am using the iTextSharp library to export a gridview with images to pdf. Some of the image urls are not directly to an image, but rather direct you to a .aspx page which displays the image. (includes a parameter with the id, and when you view the url in a browser you can see the image.) When I run the below code, I get an error that the image url in not a recognized image format.
Code:
Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition",
"attachment;filename=GridViewExport.pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);

I am trying to export a gridview that is returned from a search form. The gridview also has paging enabled. In order to export the records from all pages in the gridview I had to turn off paging and do a databind, but instead of only exporting the search results it exports all the records in the gridview.
How can I only export the records from the search results, but also the make sure the records on the different pages export also?
I have a question on the subject to export the contents of a panel to pdf, can export the panel even if it has some controls such as GridView, DropDownList, etc.? I have the following code:

Response.AddHeader ("content-disposition", "attachment; Panel.pdf filename =");
HtmlForm HtmlForm form_nuevo = new ();
form_nuevo.Attributes.Add ("runat", "Server");
form_nuevo.Controls.Add (GridView1);

I had to integrate the GridView to a form that is created at runtime because I said I should be in one, but even so when I export the file I get blank, really I do not know what I'm doing wrong and I have many controls that I have to export.
I need a query to fetch records from data from database based on partial text entered in textbox like search data from College table based on College Name entered in text box. I want that all record containing that College name displayed in grid view.

I created 3 product table . A,B and c.
I show product of table in different gridview.
Now I am using one search box. but how to search product name with image in one query all of three table....
Simple how to search product from multiple table and show result...
I'm developing a search page that will display the results in a gridview. The codebehind (in VB.NET) uses a SQL command to fill the gridview.
The gridview does have paging and sorting enabled. Once the search button is clicked the initial results are displayed, if the user clicks on a sorted column or wants to advance a page the gridview disappears. Enable Sorting And Paging Callbacks is set to True. Enable ViewState is also set to True.
I am trying to create a search page, this allows the admin to search through the entries in the database by certain criteria, such as province (like state but diff country)
Here is the code I have so far. The problem is that I am not getting any errors. But I am also not getting any results. The page just posts back and returns to the blank search page. The GridView does not display any results.
here is my code as it stands:
Imports System.Data
Imports System.Data.SqlClient
Imports System.Web.Configuration
Partial Class administration_Search
Inherits System.Web.UI.Page
Protected Sub ProvinceButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ProvinceButton.Click
'get the search string from text box
Dim Search As String
Search = ("%" & ProvinceButton.Text & "%")
'if the string has value then continue with search
If Len(Trim(Search)) > 0 Then
Dim con As String = WebConfigurationManager.ConnectionStrings("fubar").ToString()
'build sql string
Dim s As String
s = ("SELECT id, surname, name FROM orders WHERE province like @strSearch")
'declar connection
Dim c As SqlConnection = New SqlConnection(con)
'add command
Dim x As New SqlCommand(s, c)
'add parameter
x.Parameters.AddWithValue("@strSearch", strSearch)
c.Open()
Dim r As SqlDataReader = x.ExecuteReader
GV.DataSource = r
GV.DataBind()
c.Close()
Else
Province.Text = ("Please enter search terms")
End If
End Sub
End Class
On the .aspx page I have a textbox (id: province) and a button (id:submit)
I have a .net page in which i have a search button which populates the data in gridview. On Headder row of gridview i have a filter image button and when user clicks on it i need to have a div tag opened as popup and in which i have to load the data of first column data of grid view as list of checkboxs and when user clicks one by one the parent gridview need to be shortened out (reduce) basing on selected/checked item in div tag. Since the check box controls are added dynamically it need to happen in Page_PreInit, so what i am trying to do is on the search i am trying to post back the page which goes to the Page_PreInit and tries to create all these check boxes dynamically.
