I have a GridView bound to a DataTable that I construct. Most columns in the table contain the raw HTML for a hypelinklink, and I would like that HTML to render as a link in the browser, but the GridView is automatically encoding the HTML, so it renders as markup.
How can I avoid this without explicitly adding HyperLink, or any other, columns?
GridView1.Columns.Count is always zero even SqlDataSource1.DataBind();
But Grid is ok I can do
for (int i = 0; i < GridView1.HeaderRow.Cells.Count;i++)
I rename request headers here but
GridView1.Columns[i].Visible = false;
I can't use it because of GridView1.Columns.Count is 0. So how can I hide them ?
I have a gridview which makes use of a datasource. The columns are auto-generated.
Right now, my task is to make the first column into a url column. Does anybody know how to do it?

I have a "database explorer" page that is desgined to be pointed to an unknown database and allow users to browse the data, so it basically uses the SQL system tables to develop its queries and pull in data to tables using auto-generate columns.The problem that I have is that I would like certain types of columns to have certain formats and I'm wondering the best way to go about it. I could format the column in code in the RowDataBound event I assume, but I'm wondering if there some better standard way to do this? Is there a setting of any kind that I can use? For example I want all of the datetime fields to be formated for short date, like {0:d}, I want decimal fields to have 4 decimal places, etc.
View 2 RepliesI need to make a link for all the rows in one column of a gridview(VB .Net) where the grid has been auto-created from the data source. The link would simply point to another ASP details web page. The examples I have found have all been in C# and I don't quite follow them.
View 4 RepliesIt's great that Razor HTML encodes by default. However, many times I have HTML in a database and want to display it literally on a page. In WebForms 4, we can use <%= %> and <%: %> to choose between encoding options. Raven's syntax is currently @(new HtmlString(Model.Greeting)).
add a shorter syntax to Razor. Something like @=Model.Greeting or @@Model.Greeting, or something else.
I've recently upgraded a client's web site to .NET 4 and we've found out during the process that now GridView column values are automatically HTML encoded.
They have wide use of HTML strings in their code so we must turn that off. I know one solution would go over each column and add HtmlEncode="false". My question is - is there a way to set this to be the default for all GridView columns in this application?
I am currently working on a module in which I am creating an auto generated column gridview, and I have set the Auto generate edit button field to true. What happens now when I click the edit button The primary key field is turned in to edit mode which I want to restrict from being updated.
To restrict the same I have hard coded a template field which holds that column, But as I have set the AutoGenerateColumns Property to true the gridview automatically creates a duplicate field for holding the primary key column. For which I want to delete that particular column.
My Designer Code is:-

Even I have tried to hide that column doesn't make any difference for me.
I have a gridview which has autogenerate Columns Property "TRUE", and i'm dynamically binding this gridview with columns with sql database dataset. there is no data in sql but i am successful in showing blank gridview on form, now i want textboxes in gridview attached with each column, so i wrote code in RowDataBound which generates textbox automatically and assigns ID to each textbox, nw i want to insert that data from textbox to database but i'm not getting text which is entered in those textboxes, as i am accessing that textboxes using findcontrol and passing the id like gridview1_ctl03_text0. but i''m not getting any value from textbox?
In short i want to access auto generated textbox (with out any id predefined ) values from footer of gridview
is there anyway to set gridview autogenerated column width

View 5 RepliesBackground: I'm populating lots of asp.net c# GridViews and ListViews from a database and subsequently users may export them to Excel. I want export as native Excel (not html). I can't use office automation, and I'm using JET which works fine. I have no control over users' machines. Question: When doing the export, you have to tell Jet what type each field is, in my case "text" (varchar) or "numeric" (double). The difference is that if you export a numeric column, the users can sum the data in Excel, where as strings are exported with a leading apostrophe and so are not much use in arithmetic.
Currently I parse the first data row of the Grid/ListView, check if each value is numeric or text, and assign a type to the column accordingly. That works, except for when I have something in the first column which looks numeric but in fact is a text string. I don't want to parse every row in order to be sure I have the correct data type as some of these exports are quite large. When I load the Grid/ListView from the database, the database certainly knows what type each field is. So my question is... how do I extract the type of the database item behind a a Grid/ListView item? I could explicitly code it as an attribute on the item, but that's duplicating information I already have, if only I can get to it. I know that where I have a DataTable then I can get the underlying type from that, but mostly I don't have tables handy, just the Grid/ListView. Note that Jet will throw if you try to insert an empty string into a nullable numeric column. The way to do this is to omit that column name from the insert statement, or output a zero.
I would like to inquire about the delete the data in gridview with automatic number parameter ..when I edit a field with auto parameter number, how do I delete a field that does not automatically sort ..ex:
1. ROBERT
2. EMILIA
3. JOSE
When I remove the column to 2 EMILIA, then display in gridview 1. ROBERT 3. JOSE.
Coding that I got when I remove emilia then display in gridview 1.ROBERT 2.JOSE .. (sequence automatically)
private void Bindemptydt() {
//Declare a datatable for the gridview
DataTable dt = new DataTable();
//Add Columns to the datatable
dt.Columns.Add("COLUMN");
dt.Columns.Add("TEXT");
[Code] .....
string attachment = "attachment; filename=Report.xls";
Response.ClearContent();
Response.AddHeader("content-disposition", attachment);
Response.ContentType = "application/ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
GridView1.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();
The above code exports gridview1 data to excel, but the requirement is export data with row no as first column in Excel. I tried to add row number in dataset that binding to gridview, when we sort data in gridview, row number are not in correct order.
I have a DataTable where the columns are generated programmatically at runtime. I then bind this DataTable to a GridView. What I'm wondering is how I can create the GridView to accommodate this, and if it's not possible, how I can output the DataTable into nicely formatted HTML.

How can I stop ASP.Net from encoding anchor tags in List Items when the page renders?I have a collection of objects. Each object has a link property. I did a foreach and tried to output the links in a BulletedList, but ASP encoded all the links.Here's the offending snippet of code. When the user picks a specialty, I use the SelectedIndexChange event to clear and add links to the BulletedList:
if (SpecialtyList.SelectedIndex > 0)
{
PhysicianLinks.Items.Clear();

I know that Visual Studio auto-generates a lot of code when you develop a web application. How do I know which code is auto-generated? I do a lot of code editing and tweaking by hand (Im not a WYSIWYG guy), and I want to make sure I'm not editing something thats going to get over-written later by the auto-generator!

View 8 RepliesI'm trying to call a Soap Web Service, and I need to pass an Address Object to the Server. I can pass an existing address.Id to update an existing address, or if I leave the address.Id empty, it should be saved as a new Address. The Problem is that the Id is of long type, and it allways has a value of 0.And this makes problems for the server, because even if the Id=0, the Server Side function will take the Address as Existing one, and it will start to search on the Database for an Address with Id=0. Of course there is no such address, and it throws an error. When I try to call the Web Service with WebService Studio or SoapUI, and I delete the id manually, then It works as expected, as soon as I put <address id="0"> then it returns me an error - Address with Id=0 not found.So the question is, how to change the webservice definitions, or the proxy classes so that it does not generates this id="0" at all?P.S. I cannot change the Server Side method, it would have been the easiest solution, but unfortunatelly is not possible.
