Forms Data Controls :: Dynamically Populating Fields In A Gridview Depending On Data In A Table?
Jul 17, 2010
I have a gridview that is populating from a SQL DB and working fine. However, based upon certain data I find in fields in the SQL table, I want to place a 'n' or a 'y' in extra columns in the gridview that I am assuming need to be templatefields. My thought was I could maybe add 8 template columns and then I could put a 'y' in the appropriate column based upon the data I find the table. For the life of me, I cannot figure out how to do this. I want to do this at rowdatabound time ( i think) but I just cannot find out how to, in my code, put that 'y' in the columns. Is this the right way to do this or do I need to do it another way? How do I get that 'y' in the proper column?
I need to create a TemplateField column dynamically , which will contain dropdowlist controls. I've been using this example to create my first dynamic columns and for the last column, the one that contains dropdowlist controls, I've written this class:
[Code]....
But what I don't know is, where should I populate the dropdownlist control?
I'm trying to display data from this table in a gridview using template fields. Here's an example of a label in my item template
[Code]....
When i bind data to this grid view, i get an error saying column "PM 2" was not found. For some reason, the program is dropping the .5 from the column name. I am exploring the possibility of replacing the number with alphabets only but this may not be possible as the end user may not find it user friendly. Is there a way for me to get around this problem? I get a similar problem with B(a)p, it drops everything after the B. Any ideas on how to get the gridview to bind column names with special chars in it?
I'm not sure if I can explain this properly, I just need some advise. I'm working with a formview and datasets to populate the information. However I have a table specifiying which fields to display. In my table If cell, work and home fields are selected then those fields must be populated in the formview if they not selected then it shouldn't be shown. These are 2 different datasets being pulled into the formview.
Right now I have a datasource populating the formview via the wizard, not sure what to do next.
What would be the best way to handle the following scenario? I have an application where depending on what type of proceeding is selected, only certain input fields should be visible.
There are 33 proceeding types and 14 input fields in total
First case, make one big form with all of the fields and have a dropdown with proceeding type which depending on what is selected, makes certain fields visible?
I have a Grid view which is being populated from a database. Now I want to add a button that has its own html with some Hidden fields. I have introduced an Template Field and put the html in that field which works fine. But now I want to send the values in hidden field dynamically. i.e. the Id and value comming form the database.
Basically I want to populate a drop down list with time slots for a user to select. If the time slot is already recorded in the database table I want to skip that one so it doesn't display as a selection in the drop down list.
So my drop down list looks like;
[Code]....
And then I have setup a datasource (even though I may get rid of it to bind in the code behind file)
Just want to know if it is possible to Dynamically Populating a DetailsView with OleDb Data Adapter ? It has to be done on the Page_load because it has to display a users details that i must be able to edit!
I have a GridView, and I want Column1 to be equal to datatable data (filled by a SqlDataAdapter). Then I have two other fields by the SqlDataAdapter (first name, last name), and I want to have those two fields combined to form Column2. I have a TemplateField for my GridView that combines the first name and last name with Eval()'s, but the GridView places this combined field TemplateField and puts it as the first column.
How can I do this so that TemplateField can go in between fields that are databound?
I have a dropdownlist in EditItemTemplate and InsertItemTemplate which I want it to populate at the runtime while Inserting an item or Editing an item.
I am facing an issue regarding populating a dropdownlist dynamically while in Edit and Insert mode. There are 0 Records in my table and it shows "Empty Data message" in my Listview control. Even the ItemDataBound event does not fire. So I am not able to find the dropdownlist in that listview.
This is my Aspx code which shows only InsertItemTemplate and EditItemTemplate.
I have a gridview and would like to display one of 5 icons depending on the value returned from the database for that row (simply just A, B, C, D or E). Which event in my datagrid should I be looking at to check what value I'm getting? I presume once I can check a value I can simply set an image source using if statements?
I have a table in my database called "Profiles". This holds data on Female and Male personal characteristics.On my aspx, I have a formview in edit mode which is binded to an object data source with a GetDataByUserId Select methodwhich retrieves data from the "Profiles" Table via a DAL.The "Profiles" table has some columns which relates to females only and some just males and some are generic to both.See example below
UserId - / of Type GUID GenreId / of Type BOOL. Hip Size (For females) Dress Size ( For Females) ChestSize (For Men ) TrouserSize (For Men) Weight ( For both )
When the User logs in , they go to an update Page which has the Formview in Edit Item Mode and contains drop down Lists whichare binded to the Users Selected Value. The DDL are in turn bound to their related table such as HIP, Dress, Chest, Trouser etc.bjectiveIf a female user logs in I just want to show them the (Hip Size) DDL and DressSizeDDL in the Edit item template of the formview and not the ChestSize DDL or TrouserSize DDL.At present the GetProfileByUserId returns all colums from the tableMy question is how do I do this and just show DDL which are relevant to the Female or Male Only. In some cases the usermay not have selected an item in the previous form so they could also be NULL.Am i on the right path by writing a Select Query that checks to see if the User is Male or Female by checking the Genre column in Profiles first.Do I also need 2 panels, 1 to hide Female DDLS and the other to Hide MaleDDLs subject to logged in user genre.
I have a query expression which I am binding to a GridView in Page_Load. The data I want to capture in the SelectedIndexChaned event is in a BoundField defined thus:
I have a form that has a textbox, a button and a datagridview. The textbox is a parameter of @subschedule. I'm needing to pass the value of the text box to my sql stored procedure and then fill my datagridview with the results of that query.
Am using datalist to create a kinsd of message board, in the back end am having two tables one for the parent comment , and other for the child comments
The data source is extracted by LINQ to SQL with the load option , so I get everthing when I debug on the code behind , and I can see all the fields each parent comment and the child comments.
the problem is with binding the data on the disply for example all the parent table fildes can be rendred without any problems:
<%# DataBinder.Eval(Container.DataItem, "comment1Parent") %>; "showing me the orginal post"
Problem here:
<%# DataBinder.Eval(Container.DataItem, "Childcomment") %> is not rendred and I got this error msg:
DataBinding: 'DataAccessLayer.Comment' does not contain a property with the name 'childComment'. In the debug I navigate to the childComment and this is its HTML visualisar:
new System.Linq.SystemCore_EnumerableDebugView<DataAccessLayer.Comment>(((ASP.usercontrols_comments_ascx)this).Comments)).Items[0]._comments_Replies.entities.items[0].childComment
I have created DetailsView in designer page with SqlDataSource, Details view is with autoGenerateRows="false" i.e. I have declared my own fields. it is fine there, but what if I want to add these fields dynamically from codebehind with select & edit commands. I want to to use Details View in designer page and want to add fields from codebehind
I have a working gridView/DetailsView used as a member Lookup.
Some Fields in the Details View have data only some of the time, and when there isn't any, I want to suppress that row of the detail. No Go.
It seems that some of the function available in other controls don't exist so I cannot make the "field and its "header" Visible = "False"
FWIW, The control is nested inside a loginview control.
[Code]....
When I try and put logiin the control the error I get is:
Error 156 Literal content ('<asp:TemplateField ItemStyle-Wrap="false" HeaderText="PO Box:" Visible="') is not allowed within a 'System.Web.UI.WebControls.DataControlFieldCollection'. C:UsersBillDocumentsMy Web SitesNausetNewcomersMembershipCopy of Lookup.aspx 345
I would like to change color of the gridView depending on the value from table that is bounded to the grid. I actually don't show this value on the grid. I tried by using additional field with visible=false, but the cell is string empty in this way. I don't know how to solve this in some other way?
I used this code, but as I said the value is empty:
[Code]....
Is it possible to solve this by getting value directly from bounded table and not from rows cell?
I'm not sure how to search for what I'm seeking, so I'm hoping to be pointed in the right direction.
I have 4 gridviews that contain the same 3 rows of data. For each gridview, I need to create a seperate gridview that will do some calculated values on the parent gridview like A3-A1, to put it in spreadsheet terms.
And at the very bottom I will have a total gridview control that will sum up each row from the parent gridviews. And under that gridview a final gridview to perform the A3-A1 calculation.
I have a field "Active" which can contain either 1 or 0. In the aspx form, I am displaying it in a checkbox in gridview. If the database value is 1, I should have the checkbox as checked, otherwise it should be unchecked. How can this be done.
Protected Sub gvPunches_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles gvPunches.RowEditing Dim i As Integer = e.NewEditIndex() Dim ddl As DropDownList = CType(gvPunches.Rows(i).FindControl("ddlDiv"), DropDownList)
the question I have is when i enter this procedure in the code behind, ddl is nothing. what am I doing wrong in populating the dropdown for the row I am editing?
