I have a ListView with Checkbox. My requirement is - When I click on any checkbox then it should return all the columns values of that row on behalf of that CheckBox. After much study I came to know that using DataTable and DataRow I can get all data of particular ID of a Row. But I am unable to work with this. My code is something like below:
I have one big DataTable with X rows. I want to select Y rows from it and bind them to a new ViewList. While doing it, I want to delete these rows from the DataTable (Having X - Y rows).
What is the best and fast way to do it?
I don't know if it is better to create a new DataTable to have the Y and after that bind them to a ViewList or something else?
I'm also looking for example in code how to select/delete rows from DataTable.
I have two Data Table, One data table contain Product-A information, and another data table contain Product-B Information, I want to get the uncommon values between the two data table, I would like to achieve this using LINQ, find the sample values below
Product Data Table Product-A-Id ProductName W10012 A W10013 B W10014 C W10015 D
Sales Data Table
ProductId ProductName W10013 B W10013 B W10015 D X10020 AC
I want to find the uncommon data from both data table using LINQ, So find my expected Data Table result is
Result Data Table ProductId ProductName W10012 A W10014 C X10020 AC

I want to Get multiple selected column from datatable using c#. Below I have added data of datatable and I want red marked rows from datatable. Green marked text is column name of datatable.
Parameter Value GetTempFilenameResult 0 tempFilename 0 data 0 fid 0 useid 0 filename 0 tempFilename 0 userName 1 pwd 1 LoginResult 1 useid 2 usename 2 address 2 mobileno 2 emailid 2 organization 2 city 2 country 2 password 2
I have a following scenario - A use selects criterias from a webform (C#) - a result is then returned from the sql. Say, to start, there are 2000 data returned from the sql and are stored in a dataset.
Now, the user wants to choose a number of drops (up to 6) - with the number of drops selected, they can enter their own quantity in each box. So, they can divide the 2000 records into 6 different drops. With each drop, there is campaigncode created based on the mail date and the job number they provide.
So, now i have the 2000 records in a dataset. What i want to do is loop through the gridview where the user fill out the quantity depending on the number of drops (for ex: if they say 3 drops, then there will be 3 rows in gridview with 3 quantity box to fill).
In the loop, I am getting the quantity, dropdate and the job number. The Campaigncode is created as well. Then, i am looping through the datarow in the dataset; updating the Campaign Code column with the CampaignCode for the number of records thats set in a loop. It works but the Campaign Code is not populated for the next set of records.
Here is the code:
[Code]....
I think its this line right here thats causing the problem. But i don't know how to tweak this so as to accomplish what i want to do.
if (Convert.IsDBNull(DSAEFile.Tables[0].Rows[i]["Campaign Code"]))
I am trying to delete row(s) from the DataTable conditionally but I cant.
Actually I have DataList with CheckBox (default value checked=false). I am bindind DataList at run time using DataView (Dataview is created fromDataTable).
I also have <asp:Button ID="btnDelete" ....> which I am using to delete checked items in the DataList (But this functionality is not working).
The user first "checked" items in the DataList and click the the button "btnDelete". Here nothing is being deleted (?) and the DataList appears with all the items"unchecked" (even those which the the "checked" by the user). protected void btnDelete_Click(object sender, EventArgs e) . In this function I am checking state of the checkbox before deleting the row in the DataTable.
On PostBack generated by the "btnDelete", DataList appears with checkboxes unchecked therefore nothing is being deleted
I am working with GridView/TelerikGrid control. It is having filter option. When I filter the data, I need to copy only filtered rows into Datatable for further processing.
Suppose I am having total 10,000 records. and when I filter on column say Dept="IT", I get 1000 records in grid. So these 1000 records only should get copied into Datatable. So How to achieve this ?
Cwhat can be done over this ? I tried number of properties for grid. But there is no property which will return fileterd data source. Also I am not able to go every page of Datagrid and collect the data. I can get data for first page only. If I need to collect the data by going to every page of gridview, what is the way for this ?
In my continuing effort to build a search page that sends gridview rows with a textbox txtQty <> 0 to a listbox via a datatable, I've written the following:
[Code]....
The page runs, I'm able to input values into the textbox and when I press the Add to Quote button inside my gridview, nothing is populated inside my listbox. Am I correctly binding my datatable to my listobx?
Referring [URL] .... its a good functionality but instead of removing duplicate rows i need to make the cell of the column containing duplicate value blank
How to Disable user click on Gridview header and first two columns? I am using a modalpopuextender for which girdview is used as targetcontrolid. I need to pop up panel2 when user clicks on anywhere on the gridview except the gridview header and first two columns.
So I've been teaching myself ASP.NET and VB for about 3 weeks now, having trouble with datatables, not sure how to get the rows to line up like I think they should. My code:
[Code]....
Which gives me the data output I want, but the days are adding rows underneath the previous day instead of lining up side-by-side. The idea is that once it's working I'll replace the specific dates with calendar controls. The gridview currently outputs like this:
I want to orderby the list. Today date is on the top and then next date and all dates but when today date is passed then it comes on the end of the list. Is there any formal query in linq or some other code is used to achieve this?
08/01/2015 09/01/2015
but when today is passed then it automatically go to end and next today date is on the top
