View 1 RepliesForms Data Controls :: Findcontrol In A Gridview / Give The Controls Unique IDs
Sep 14, 2010I've got a gridview with a few textboxes in each row which I want to insert into a database, after a user clicks a submit button (thats outside of the gridview)
This is my code for the gridview
[Code]....
And this is my code for the button
[Code]....
But when I click the button it gives me this error
"Multiple controls with the same ID 'Label12' were found. FindControl requires that controls have unique IDs."
How do I give the controls unique IDs if they are in a gridview and the rows are database driven?
Validation For A Unique Property?
Jul 20, 2010Does anyone know how to do validation for a unique property or can point me to an example? Say I have a grid of movies and I do an edit or an insert. If I set the textbox 'Title' to be 'A really cool movie'. How would I do the validation to ensure the database doesn't already contain a movie by this title? Would I use a CustomValidator? I tried doing this but when I was checking the text in the textbox it was coming through as an empty string.
View 1 RepliesValidation For Unique Properties Method?
Apr 4, 2011I was trying to write a method to be called from a CustomValidator to determine whether a string property was unique or not. I was trying to make it generic so that I can reuse the code for many different string properties. I'm using reflection. Does this seem like a way too complicated way of doing this? Does there happen to be a better way of doing this but still making it generic?
public virtual bool IsPropertyUnique(T entity, string newValue, string propertyName)
{
var values =
Context.GetTable<T>.Where(e => string.Equals(e.GetType().GetProperty(propertyName).GetValue(e, null), newValue)).ToList();
return values.Count == 0;
}

Forms Data Controls :: How To Apply Validation Controls On Gridview Which Is Created Dynamically
Aug 31, 2010i created a gridview with two columns and 8 rows dynamically. All the rows are empty and editable at runtime. I am giving column names for this grid from some other .aspx page by passing column names using querystring.Because i am using this grid for three different pairs of column names. i would like to know how to apply Required Field Validator, Regular Expression Validator and Range Validator on Gridview textboxes. So that by using those validators i want to validate user inputs. And i would also like to know how to add rows at runtime for this grid.
I am using ASP.net 2.0 and C#.net for this.(Visual Studio 2005)
The code i am using to create gridview is below.

Forms Data Controls :: Can Do Javascript Validation On Gridview Emptydatatemplate Controls
Sep 22, 2010The requirement is like the users should enter data and should be able to see the entered data before final save. So, I've taken a gridview and binded it to a temptable which will don't have any data initially, so on the first page load the datasource will be empty and the emptydatatemplate will be shown to the user. On this EmptyDataTemplate I've prepared a dataentry screen where the user can give the information and can save the data. After saving the data the data will go to the temptable and the gridview will get populated with the data the user has entered. For next go, the user can enter records through the gridview footer row. In this way I'm doing my things.
Now I haven't done the validation yet, I wanted to do a validation of the user input on gridview emptydatatemplate and gridview footer as well. In order to do that I've created one Button object on RowDataBound and assigned the gridview emptydatatemplate save button against it and also binded one javascript function with this button like below.
[Code]....
The javascript is working fine and returning boolean values based on the validation done.
But the problem is after I did this validations the RowCommand event of my gridview is not firing. I'm inserting this records on this event only based on the commandname of the button. But if I remove this javascript validation everything works fine for me.
Forms Data Controls :: Get Cell Values In A GridView After Dynamically Adding Validation Controls?
Mar 31, 2010So I have a gridview control and I am binding it's datasource dynamically base on a dropdownlist. The gridview contains autogenerated columns with auto generated edit buttons. The datasource binded to the gridview is IQueryable<T> where T will be different for different datasource.
My detail problem is below:
A GridView binded to datasource dynamically with all autogenerated columns. When user click edit link, it will display value in autogenerated textboxes.
When user click update link, I am able to capture the user entered value in the textboxes in RowUpdating event, then pass those values to Linq update function to update the database. Now, the problem begin when I try to dynamically add validation controls to each editing row. In RowDataBound event, I am checking the editrowindex then adding validation control to gridview cell and pointing to cell.controls[0] which is the textbox control when the row is in edit mode, I am dynamically setting the textbox control id so that the validation control can set controltovalidate property. The validation control works, but the updating function is setting everything on the grid to empty string.
I am check the textbox text value in the loop, which returns "" for all cells except the id column. It was returning the correct value before I add the validation control. I guess since I added the validation control on rowdatabound event, will it rerender it's own autogenerated textbox in edit mode so that the text value of textbox no longer available in rowupdating event?
Is there a better or correct way to get the cell textbox value? I am using ((TextBox)dc.Controls[0]).Text where dc is DataControlFieldCell in rowupdating event.

Data Controls :: Validate Multiple Validation Groups In GridView
May 7, 2015I have a Dynamic GridView on a page as below. The user can add or delete rows. When inserting record, the code is executed one row at a time. I have 3 rows to be inserted to the database. Here is the issue:
-if the first row is not completed, then no record is added to the database
-if the first row is completed and the second row is not, then only the first row is inserted in the database
-if the first row is completed, the second row is not complete, and the third row is completed, then only the first row is inserted in the database.
below is the code:
protected void GridView1_AddNewRecord(object sender, EventArgs e)
{
string constr = ConfigurationManager.ConnectionStrings["DatabaseVestConnectionString1"].ConnectionString;
SqlConnection con = new SqlConnection(constr);
SqlCommand cmd;
string query1 = "INSERT INTO kart_Bestilling(SakBehandlingCode, KystverketRegionID, KystverketAvdelingID, BestillerReferanse, BestillerLeveringAdresse, BestillerPostKodeBy, BestillerNavn, BestillerStilling, BestillerEpost, BestillerTelefon, BestillingBeskrivelse, BestillingDato, BehandlingSakNummer, BehandlingBeskrivelse, BehandlingStatus)" +
[code]...
How to arrange this piece of code to validate all rows before any insert? or avoid inserting a row if there is one row not complete?the conditions starts with int rowIndex = 0;
if (txtBestillerReferanse.Text != "" && txtBestillerEpost.Text != "" && txtBestillerNavn.Text != "" && txtBestillerPostKodeBy.Text != "" && ddKartTypeName.SelectedValue != "Velg KartType" && ddKartNummerName.SelectedValue != "Velg KartNummer" && tBestillingAntallKart1.Text != "")
