How can I convert the following aspx code into code behind code?
[Code]....
I want the following code to be craeated on the fly (runtime). I will only add the root level grid to aspx and then in page load I want to add subsequent grids.I know we will use GridViewTemplate to add the grid but not sure how to structure it. The steps that I follow:
1. set the required properties of gridLevel01.
2. add BoundFields for level01.
3. Add template field for level02 grid....but not sure how to set other required properties like color and stuff....also not sure what position to add the subsequent gridviews.
Do I need to add the child grids to root?? I know the level2 grid will be added to level1 but what about level 3?
My web page will get a set of results from the database and display it to the user. However I am not sure about "number" of results.Each result will have a panel which contains several controls in itself, an image, several labels, etc.What is the best way to do this dynamically, eg. create these controls dynamically?Is it better to use an AJAX control? Should I use Gridview?
View 3 RepliesMy problem would be the following:
Lets say, I have to create a few buttons runtime ( LinkButton b = new LinkButton(); setting an ID, text, Click +=, etc )
the problem is, whenever I create a button (or such thing) outside of the Form_load or PreInit, the OnClick event just doesn't occurs.
I need to create dynamic fields (textbox,combo) based on the entries in an XML file
I will read the ATTRIBUTES XML tag and must create the type of control and add validations to it. Can someone say how to use MVC3 to create dynamic controls, becos i cannot have different class for models as the XML file will change for each screen and i will have one screen which will generate this page for me...
I have a project where I need to create menu buttons from a list in SQL Server. The problem I am having is that I need to add code to the text of those buttons. So there would be a birthday button and it should display the number of birthdays within the next two weeks or a button with the number of upcoming events.
Clarification:
There is no code yet, just some requirements. What I am doing is querying a table to get the list of buttons to display. Now each of these buttons may have dynamic text, for things like count of birthdays, events,etc... I am trying to see what the best way would be to handle this. Should I embed a snippet of code to go along with the menu item to execute when I iterate over the menu items? Maybe I should build a javascript file to go along with the code, which I add code to query a service for certain menu items?

I'm using CRv9 and want to make use of Google Charts API for generating QR code on fly (in asp .net) and display it in the Crystal Report in a PDF format.I have spent the whole day looking for solution with no luck. The way we output the report is we use .rpt file, feed it with data and use Response.OutputStream to feed to browser. No CrystalReportViewer control hence CSS solution is not an option.
Now, I got as far as added an OLE Object from file with Link, which I would be overwriting every time the new QR code is generated. I apreciate that CR requires it to be a bitmap, so I was planning to download and convert the google's generated PNG file to BMP, that's not an issue. The problem is that Image in the report does not update after I replace the file. Meaning, it displays the original image, which was added as an OLE Object.
If I open this report in CR designer, the image gets refresh/updated and I'd have to save changes to the report to see this new image next time I generate a PDF file.The question is really how to achieve a dynamic image in Crystal Reports 9? Remember, Picture object did not have a Graphic Location property until vXI, so I cannot use that.
Manipulations with DataSets is not an option either as we're not giving report a datasource, instead we just map the fields with FormulaFieldDefinitions.

I am trying to create a composite control - A textbox, gridview and a button. When I create the grid dynamically, I use my function GridViewDataBind() that will basically create the gridview at runtime and bind it with data. In this method, I add a blank column (first column for expand/collapse image), databound columns (using custom Itemtemplate), a placeholder, then a new html row/cell and a child gridview. I want to know how can I add these html rows/cols to my gridview. Here is the code:

Not sure if the approach is right and if I was able to explain my problem?

View 2 RepliesI'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 + "%') ";

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;

I'm trying to add an DropDownList to a DetailsView by code, because i'm writing a solution that let's the user select an table and view your records and edit them, some of theese tables, have a foreign key column and the user must have to select some item in the list.
Below is my sample code:
[Code]....
the code above is working correctly, when the user click in the buttons New or Edit , the DetailsView opens correctly, showing the DropDownlist, but when the user click in the buttons update or insert , an error occurs, the viewState cannot be loaded:
Failed to load viewstate. The control tree which viewstate is being loaded must match the control tree used to save viewstate during the previous request. For example, when controls are added dynamically, the controls added during a post must match the type and position of the controls added during the initial request.
