I have a Gridview with autogeneratecolumn = yes since the datasource always returns different columns of data.
However, except from left most column, all columns to the right should be formated to #,###.#
How could I format these columns to the right dynamically ?
I am dynamically binding dataset to a gridview(No Columns at design time) .I need to show Totals for some of the dynamically generated columns in the footer.

I have a Gridview on my aspx page. On my page_load event I check for a record in the database, if the record exists for that row in the gridview I would like to add a new column in the same gridview and add a button control to it. This adding of new column in the Gridview should happen in the codebehind (c#). see the code I wrote for this, but when I run it, it does not create any column on the gridview page.

i need to add a hyperlink to each gridview cell and when that cell is clicked pass the header text through the querystring to another page. I can access the cells value ok and pass that through but i cannot seem to access the cells column header text. when i response.write out a count of the gridview.columns it brings back 2 which is the template fields but not the dynamic fields i have tried this on the rowdatbound, rowcreated, page_load and page_unload. the count should be 12 its like it cannot find the dynamic columns at all. ?
here is my code for populating the gridview

I have a gridview, where I set the columns based on the columns in a datatable. I have a class that implements ITemplate, and creates a textbox template field. Everything works good, I can display my grid with the correct columns and headers. The probem comes up when I click a Save button, to save the user input. Of course the page postbacks, and I re-create the columns on PageInit. However, all the data the user entered is gone.
View 2 RepliesMy datasource is an ado data table that I have convert to a new data table so that each row in the original table is now a column with 1 row in my new table. I then bind the new datatable and create dynamic template fields with a text box where I bind the values. My problem is, when I try and retrieve the values changed by the user in the rowcommand event, the template columns no longer exists.
Does anyone know how i can retrieve these values? I've read over and over that you have to rebind the grid on each postback when you use dynamic templates, but I'm not sure how to do that and retrieve the values entered in the text boxes on the client side.

I created a gridview that is made up of 4 gridviews and using a stored procedure to populate it. I create columns at runtime because the number of columns changes all the time.To make the grids editable I am adding template fields at runtime as I create the columns, this is to ensure that a user is able to edit the cells and some foot values update. Reason why I have four grids is to freeze rows and columns like in excel using javascript. The problem is that performance is very bad especially in IE, the grids take a long time to load. I am not sure if this is caused by the data load or the creation of text boxes. see some of the code below for my _aspx page:

How to add dynamic columns in Gridview?
View 1 RepliesI'm looking for the best way (Performance) to do gridview columns formating RunTime /Dynamic depending on the datatable Columns type ,I want to bind the datatable to a gridview and format the Date columns to short date, and currency columns formatted with comma ex 10,000.00 inplace 100000.00 at datatable the column type is double run time (without converting them to String) since I do a filtering and sorting at these columns.
View 3 RepliesI've created a filter textbox for searching my data in gridview..

I ask, how to create a dynamic search for 3 columns in gridview using a textbox?
without writing a query repeatedly :(ID like '%" + search + "%') OR (NAME like '%" + search + "%') OR (DATE like '%" + search + "%')
protected void btnCariConnStrSubmit_Click(object sender, EventArgs e) {
string search = ((TextBox)GridView1.HeaderRow.FindControl("txtCariConnStr")).Text;
string sql = "select * from report where (ID like '%" + search + "%') OR (NAME like '%" + search + "%') OR (DATE like '%" + search + "%') ";
reader = mda.GetData(sql, connStr).CreateDataReader();
if (reader.Read()) { dt = mda.GetData(sql, connStr).Tables[0]; BindGridView(dt); lblRecordNotFound.Visible = false; }
else { Bindemptydt(); lblRecordNotFound.Visible = true; }
((TextBox)GridView1.HeaderRow.FindControl("txtCariConnStr")).Text = search;

Initially, I wrote the GetTeamMember() method to display the FullName in the ItemTemplate.
Then as I wrote the EditTemplate, I needed to populate a DropDownList with a list of names (first and last). It was fairly easy using the LinqDataSource, however it currently only shows the LastName. I could write another method GetTeamMembers() to populate the ddlTeamMember with the data I want, but I thought maybe there's a better "LINQ" way.
So I'm looking for a better way to get FullName (i.e. Firstname + " " + LastName) into both lblTeamMember and ddlTeamMember.
Options I thought of are:
I could write a method GetTeamMembers() I write a StoredProc that returns the extra column Better way?
I have a requirement where on the left hand side we have a tree view control and on the right hand we have dynamic columns.
Below screenshot gives an idea of the requirement. what is the best way to implement this?
Year1, Year2, Year3 are dynamic and are based on the user input.
I put in my page 1 table like grid with this style:
header of columns are select from table persons(so number of them are dynamic)
header of each row are select from table goods(so number of them are dynamic)
in table , in each cell,show the price & the date ,that this person,buy this goods
for example,in may 2008 ,Jack&sara buy pencil.so in front of pencil&buttom of jack we write his price and in front of pencil&buttom of sara we write her price.
so this table has 2 column & 1 row
in may 2009,
Jack&sara buy pencil.so in front of pencil&buttom of jack we write his price and in front of pencil&buttom of sara we write her price.
and jhon buy pen & suzzan buy book so this table has 4 column & 3 row
Price Date
Price Date
Price Date
Price Date
Pencil
Pen
book
then I want in each cell,I have 1 CHECKBOX that user of my program,checked each on that want. how can I design my page?
is ther any component?or I must create <TABLE> dynamically

If there's a better way to accomplish what I'm attempting I haven't found it yet. That being said, I have create a gridview like the one here,[URL]And with some minor tweaking it working great for all my fields, checkboxes, etc. The issue is my last column is another gridview, and I'd like it to function the same. that is, a dynamic gridview inside of a dynamic gridview. I get that I have to create it initially with null values or it won't show up. I guess what I'm having trouble figuring out is instead of go will null data in the parent gridviews column, do I place my blank child gridview. Do I create and bind the child gridview first, or second. Generally just not sure. Also, as far as storing the data from the child gridview goes, will each one need it's own datatable?

How to dynamically assign a datasource to a DataList ?????????

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.
