Something like this Are there any solutions out there to accomplish this? Preferably in .NET but I am considering any solution that this available.

Forms Data Controls :: Find And Set DetailsView Controls In Empty Data Template In Gridview
Oct 31, 2010I would like to find controls in the detailsview control placed in the EmptyData Template of the gridview. I am trying to create Insert new record for the gridview control.
1. If there are existing records in the table - works fine and sets my two values: I placed Detailsview and Insert Button in the footer of the gridview. I needed to set the values of two fields. When I click on the Insert button it saves new record and sets the field with the value (code attached - works fine). I also have a popup extender that opens detailsview - this works just fine.
2, If ther are not records in the table - saves record but cannot find and set controls on the detailsview Same thing setup in the EmptyData Template. The record is saved but I cannot Find and set the field value on the control.
1. Link button (on click) in the gridview footer (works fine)
protected void LinkButton1_Click1(object sender, EventArgs e)
{
string zupa1;
zupa1 = ddlSelectEmployee.SelectedValue;
try
{
DetailsView zupa = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1"); TextBox zupa2 = (TextBox) zupa.FindControl("txtInsertEmployee");
zupa2.Text = zupa1;
}
catch
{
}
DetailsView dettraining = (DetailsView)gvTraining4.FooterRow.FindControl("DetailsView1");
TextBox training = (TextBox) dettraining.FindControl("txtTrainingType");
training.Text = "4";
}
2. EmptyDataTemplate.FindControl - can save record but cannot access txtInsertEmployee and txtTrainingType
DetailsView zupa = (DetailsView)gvTraining4.EmptyDataTemplate.FindControl("DetailsView1");TextBox
zupa2 = (TextBox)zupa.FindControl("txtInsertEmployee");TextBox
training = (TextBox)dettraining.FindControl("txtTrainingType");"4";

Forms Data Controls :: Finding And Inserting Data Into Controls Inside A Gridview
Jan 25, 2010Im having trouble accessing controls inside the gridview. I have a formview control on a aspx page and inside this formview i have controls that are bound to a datasource. Which works hundred percent. Also inside this formview i have a gridview which i have created my own template. Gridview1 has 3 columns with textboxes in each column.
Column 1 - LogDate
Column 2 - LogBy
Column 3 - Number dialed
Now this is what im trying to do. I have a dial button inside formview1 along with 4 textboxes which has telephone numbers in it. When i click on the dial button i want the time to be populated into Textbox1 which is inside gridview1 and at the same time Textbox2 to be pupulated with the Username as well as the number must be populated into Textbox3 inside gridview1.

View 10 RepliesData Controls :: Add Dynamic Rows In GridView With TextBox And Keep Edited GridView Row Data On Post Back
May 7, 2015I have 3 textboxes , 1 dropdown , 1 Button and 1 gridview .
Textboxes ID are :ACode , ADesc , ASeq
DropDown ID is :CPhase
Button ID is :AddRowBTN
GridView ID is :PhasesTempGrid
Now whats the story is ?After adding some data into textboxes , when a user clicks ADDRow BTN , that data gets saved into datatable , then that datatable gets binded to gridview and it shows my textboxes data in it .
What i want to achieve ?In my gridview i am use templateField and inside that template field there are textboxes ( Let the users edit the row without clicking any button ) .
Take an example of dummy data and problem persisting in there :for e.g i put some data in textboxes :ACode = "ABCD"ADesc = "EFGH"ASeq = "HIJK"Then i click Add BTN , it saves the data in datatable and show in gridview , now if i do this in gridview :ACode = "Edited ABCD"ADesc = "Edited EFGH too"ASeq = "WoW There"Then i click Add BTN , it removes the edited record in gridview and shows original data which had came earlier from textboxes :ACode = "ABCD"ADesc = "EFGH"ASeq = "HIJK"I don't want that to be done ... Simple is that user can enter data from textboxes , click the btn to submit into grid then he can edit the data like he want ... data must not get flashed , here's my coding i have done so far :
public void AddNewData()
{
var dt = new DataTable();
if (ViewState["myDatatable"] != null)
{
dt = (DataTable) ViewState["myDatatable"];
}
[CODE]...
here i havent added dropdown combo in gridview but you can do it so that it will save my time (Bind it just the way PhaseDropDown have bind)...
