I am to design a report which will be having given rows, I have tried with Tablex and Matrix, but I am facing issue with grouping.
Is there any other control or any custom control or any way of customizing Table
which I can use to design the following formatted rows in report.
Any link with demo, sample or POC would be great help.
Kind hard to tell what you're going for from your picture/description, but I'm guessing you may want to use a List object. You can put your group at the list object level, and then add text boxes, tables, images or whatever you need inside the list. You'll get a set of whatever is inside the list for each group, using the data from that group. Take a look at the sample/description here, which looks similar to what you're trying to do: here

I wrote my own sub-class, for some selection stuff and paging etc. But those all worked with the renderer(), which required them to return a string.
This worked fine, I created some image-tags and returned those.
But how does this class work in detail?
I want a sub-class which displays a chart in a cell, which should technically be no problem, but the renderer() doesn't seem the right place for it, since it only works for strings.
Does the Class get instantiated for every row? or is it really just one instance for a column, which methods get called for every row with the needed data and the instances don't hold any state about the rows?
The renderer() mechanism is actually implemented in Ext.grid.column.Column, for which there is one per column.
As you have mentioned, the renderer() function returns a string, which could be an HTML string (which could be rather complex - have a look at the templates used by ExtJs for the standard columns). But you cannot return a component (chart).
To the best of my knowledge (based on my own understanding and replies to similar questions), ExtJs does not offer a straight-forward way to render components within grid cells. If you really think about it - you are asking a grid for much more than its intended role. It was designed to present records per raw, with the addition of simple user interaction facilities, like checkboxes.
But what you are really asking for is more of a way to layout charts, for which problem i suggest you look into the Table layout.
Alternatively you should be able to render a chart into a dom element, which will be defined in your own custom column template. But I will consider this to be an involved task.
I have an Ext.grid.EditorGridPanel in which I defined several columns.
Per each of the columns, I would like to allow the user to select a subset of items and then present only the rows that contain the selected values.
I thought of something similar to Excel's filter option.
I could not find a method that suits my needs in the Ext 3.3.1 API documentation but I am very new to this so it is quite possible I missed it...
Is there a simple way to do this?
Thanks!!!
First of all your grid panel will be getting data from some kind of data.store http://docs.sencha.com/ext-js/3-4/#!/api/Ext.grid.GridPanel-cfg-store. And there is a way to apply filters according to your rules. See the method description on Sencha documentation: http://docs.sencha.com/ext-js/3-4/#!/api/Ext.data.Store-method-filter
I am developing a winform application application. I wanted to show sum of columns in last row of each column. This row must always be visible.
At moment I am thinking about adding another datagridview just beneath my datagridview with records, and would show the sum in that bottom datagridview.
If there is a better way to achieve this task?
No, need of adding another datagridview
Solution 1: Please refer to this solution
Solution 2: If the above link is not exactly what you want then,
You can try to manually add last, summary, row in which you can display information that you need. For example, you can try to do the following:
Read data from database and fill System.Data.DataTable
Add one column to the newly created DataTable – that column might be set
to true for the last, summary, row
Programmatically add one extra row that contains suitable summary data
Do the data binding to DataGridView control
Using appropriate event, bold or otherwise graphically distinct summary
row (row that have extra column value
set to true)
You can do it in the same way as you suggest, like placing a datagridview for displaying the sum. you can also handle the Horizontal Scroll with this, if there are more columns.
Another method is there in this link
Another way you can Add Rows to your datasource itself to display the sum.
Even if this question is quite old-ish I'd like to propose an extension to Niraj Doshis answer. His answer holds true for a data bound DataGridView. I recently had the problem to calculate the summary in a user-editable DataGridView, whose solution differs in the details. Anyway It's quite straight-forward too. I am writing my functions on a higher abstraction level, which outlines the workflow, but elides the implementation details.
First of all you'll have to initialize the DataGridView, see
private void InitializeDataGridView()
{
SetColumnTypes();
AddEmptyRow();
AddSummaryRow();
}
I set DataGridView.AllowUsersToAddRows to false for the new row would be located beneath the summary row. Hence I am adding an empty row, which the user may fill with his data. The summary row is set to ReadOnly since we do not want our user to edit it. Whenever a CellEndEdit is raised I am updating the DataGridView with the following method
private void UpdateDataGridView()
{
RemoveSummaryRow();
RemoveEmptyRows();
UpdateRowNumbers();
AddEmptyRow();
AddSummaryRow();
}
First I remove the summary and all empty rows (you'll have to take care. If you are trying to delete the row you just edited an exception will be thrown. I've not yet figured out how to do this, but I just made up the solution. I'll amend when I came up with the solution.) Afterwards I'm setting a running number in each of the rows. This is not really required, but a detail of my implementation. At the end I add an empty row again which the user may use to add further data and then calculate and add the summary row.
As I said before this is not yet a ready-made solution, but rather I concept which works but with some quirks and bugs.
Help
I am attempting to create a drill down report using report server and Visual Studio 2005.
I have been able to create a tree structure, but the original report looks like it opened a new report. (Crystal Report)
This was done by the report hiding all other data apart from the drilled data and the data title.
I can’t seem to be able to do this at the moment or seem to find any help online to do what is needed.
Does anyone know how I can do this or know of any material online that could help?
Thanks
i can think of two different ways to interpret your question. 1. you want a table in a report that, when the user clicks on a specific row, drills down into the report. 2. you want a report that, when a user clicks on certain rows, it opens up another report that's a drill down of the data. for option one, read my blog here and tell me if that's what you're looking for.
Not sure which way you're asking, so I'll list both.
For all your data on a single report which is grouped you can right click on the row indicator on the table and select properties, then visibility. Inside visibility you should see a checkbox with "Display can be toggled by this item" then the dropdown will have a list of textboxes that are on the report. Just select the one you want to control the drilldown.
The alternative way is through report actions, which you create a separate report with or without parameters, and select the textbox and choose properties, goto action, select "Goto Report" then select the report to drill down to, and add your parameters.
Hope this helps.
I'm currently facing the problem, that I import an Excel file to a DataGrid.
This works pretty fine, but after importing the table, I need to know how many rows are invalid.
I have applied several validation rules for the different datatypes, and I have an icon in the row header, that shows up if the row is invalid.
But since I have more that 10.000 rows in the grid, I don't want scroll all the way through it to find the errors.
Any ideas, how to determine the count of invalid rows (and then maybe bind that to a textbox)?
Thx
Well, if you're using WPF in the manner that I would term to be "correctly", you shouldn't care about the DataGrid itself in order to get the results you want. You could just run a simple LINQ expression off of the data that the grid is bound to coming up with the count of invalid rows.
That is indeed the solution to one part of the problem. But the user can also edit the values, so they are validated before they are written back to the datatable...
Your approach would cover the import (null values etc.). I think that I have to write an own class, that iterates through the rows and their rowerrors...
