View 15 RepliesHow to add dynamic columns in Gridview?
View 1 RepliesI have one two GridViews on a page. One Gridview uses BoundFields inside of the GridView and the Update statement works just fine. The other GridView utilizes TemplateFields due to the fact that Validation Expressions have to be used. I also want This GridView to be able to update the vlues when the user clicks on the Update link on the right side of the GridView. The GridView that uses the BoundFields updates just fine, but the GridView that uses TemplateFields will not update. I have checked and everything is correct other than this difference of BoundField and TemplateField.

View 1 RepliesI have a gridview where I in codebehind add a templatefield
[Code]....
In my update command when i try to find the "Result" textbox I get a null object
[Code]....
In the gridview there is another templatefield "Name" that consist of two boundfields("Firstname" and "Lastname") This column is added in the design phase and not in the codebehind.I don't have any trouble finding these controls using the ID added in the markup
[Code]....My issue is with the result column that I add in codebehind.
I already implemented the dynamic templatefield which will re-created in every postback. Everytime I make a postback in the page I see no problem but when I click my imagebutton inside the gridview then the dynamic templatefield disappear.
To double check if it is really gone at all I just select the second page of the gridview using my customize paging using dropdownlist outside the gridview and the templatefield with its correct data reappear again.
I already put a variable inside the rowcommand to see if the number of columns are the same with the number of columns the gridview render together with the dynamic templatefield during debugging and it is there but cannot render that templatefield in the client.
(Example code below)
I have a GridView. It has a 'static' TemplateField (in the .aspx page). I add and remove BoundFields to it depending on user preferences on postback. Affter the second postback, the template field appears empty.
Here is a stripped down mockup of what I'm doing. You can click the "Regular Postback" button as much as you want, and nothing bad happens. But if you click the "Recreate" button once-- it's all ok. Click it again, and the "one" column goes on Christmas break.
So is there something else I should be doing, or is this going to be a "halcyon1234 to code interface" error.

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.
View 3 RepliesI 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 ?

how to create dynamic template columns in gridview .

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.
[Code]....
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:

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've created a filter textbox for searching my data in gridview..
ex: i've 3 columns in gridview : ID, NAME, DATE
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;
}
My 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 have a grid view with all columns as TemplateFields( No BoundField). Based on certain condition i have to set Visibility of few columns false. Suppose when there is no column 'CaseList2' in the DataTable, then the second column of the grid (whose column index is 1 )should be invisible. But when the Gridview binds it gives error DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'CaseList2'
i googled it and found that
GridView1.Columns[1].Visible = false;
should work. But its not working actualy.

I work on a custom server control that contains two grids with dynamic templatefield checkbox , the 1st one binded by SqlDataSource, the 2nd grid filled with selected rows in the 1st grid, all is clear, the 2nd grid filled appropriatly but when a button(out of the custom control) click event fired the grid disappear , Second and what is important is how to save state of the checkbox while after postback I must create the field and bind the grid ?
for Template field :
class CheckBoxTemplateHandler:ITemplate
{
void ITemplate.InstantiateIn(Control container) [code]....
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 Repliesprotected void Button1_Click(object sender, EventArgs e)
{
System.Collections.ArrayList list = new System.Collections.ArrayList();
list.Add("abc");
list.Add("xyz");
list.Add("pqr");
list.Add("efg");
GridView1.DataSource = list;
GridView1.DataBind();
}
Now when data is bound to the gridview the column name is by default "Items" but I want to change the header text of this column.
I am binding a GridView using a DataSource in asp.net, and i would like to have some hidden BoundFields so I can access those values in my RowDataBound Function. However, when I set Visible="False" on these BoundFields the values do not get set and are always blank in the RowDataBound function.
I've seen some suggestions of setting the style on the BoundField to hidden but this did not work for me either. Ideally I don't even want a column created in the gridview, I just want these values to be hidden so I can access them.
