Data Controls :: Find DropDownList And Access Its Selected Value In GridView Row?
Jan 4, 2013
i have gride view and there are three dropDownList in every row in grideview,i want get selected value from every DropDownList,and pass the values to storeprocedure in sql,I dont know how pass value every row, to store procedure,and StoreProcedure get 3 value.
i know how to find the index of selected row in asp gridview , but i need to find the index of selected column in asp gridview ?for ex:i have i gridview contains columns with header ( the header is the primary key i looking for ) , this grid contain linkbutton , i want to get the column header name on click on linkbutton ?
i have one dropdownlist and a button. one i click on the button other gridview will popup. in that popup gridview i want to select only one value and bound that value to dropdownlist. How can i do this?
I have a Grid on my page.When the page is loaded for the first time ther is a list of records displayed in the grid.When I edit the record by edit link button,the ddl saves the change value .
The same thing if I do when searching for a particular record and then editing and changeing the dropdownlist value,the page postbacks and the new value gets replaced with the old value that was present earlier.
And inside that gridview you can see I have a dropdownlist called dpdTrueFalse. That dropdown has two values which I am loading from code behind like this...
[Code]....
I have a submit button outside that gridview that checks each row and the selected value in the dropdown. But for some reason, even if you select another item in the dropdown, it always selects the first item in the dropdown when I click the submit button. I reckon its because of the postback.
I want to display a GridView using the the selected DataValueField from the DropdownList.
I've set the Selectparameters for the GridView DataSource.
Here is my question: on clicking "BtnSelect" - How do I assign this parameter (@Id) to selected value (DataValueField) from the DropDownList and re-display the grid view accordingly?
Came accros your article "How to populate DropDownList in GridView in ASP.Net"
[URL] How-to-populate-DropDownList-in-GridView-in-ASPNet.aspx. Was able to duplicate your code w/o any problem. Works. Noticed that the values selected from the DropDownList are not automatically saved in database.
Question: is it possible just by selecting an item from DropDownList and then moving to another row within GridView save a selected value? I mean without using edit/update/cancel buttons but just by selecting an item from the DropDownList.
No you cannot add a third parameter in the Dictionary. It contain Key Value pair data.But if you want to add third parameter then simply use DataTable and add these in the DataTable row.Name of Builder , Title Of Buidler , Builder ID
So how to acheive that task ? so far i did like this :
public void AddNewCMP(string PersonName , string PersonID , string PersonTitle) { var dt = new DataTable(); if (ViewState["CMPDataTable"] != null) { dt = (DataTable)ViewState["CMPDataTable"];
[Code] ....
Now on button click i want to add six drop down values to AddNewRow(value1,value2,value3) method .... how to do that ?
GridView gvchild = e.Row.FindControl("gvOrders") as GridView; drplist = gvchild.FindControl("drp1") as DropDownList; // den also same error object reference not set to an instance of an obj
In ASP.NET, I can get the selected index of dropdownlist using:
var dropdown1 = document.getElementById('dropdown1');But I want the selected index of that dropdownlist, which is present INSIDE a GridView.How to get that using JavaScript?
I want three fields in dropdown list in gridview . Pending , Solved , Escalate.
When I first submit the record it should show pending, then from dropdown I want to update it to solved or escalate , and it will be update with dropdown in database. How can I do this process....
I have seen a lot of things on the net on this but nothing seems to work. I have a GridView with name and other information on files stored in a database but also on a Server. I display the gridview with the files and the user selects the file to delete (row) by hitting the command field for Delete. I have an event on the gridview for code behind. Here I want to access the file name for the row selected, to be able to include it in the File.Delete statement.
Even before this I want to display the selected file name in a label back to the web page. I have tried everything including findcontrol selectedValue, etc. Nothing is working. I either get complier error, or nothing is displayed in label. If I let it go the the File.Delete step I get access error becasue there is no file name. HELP. here is screen shot of the gridview. Ignore the download button for now. That is my next headache to figure out. So based on the screen shot I want the value of log_doc from the gridview. It is in a column called file_name
File ID File Name Log Upload Date Uploaded By Download Delete 3
How to display the selected value of a dropdownlist in header taemplate of a gridview? As i change the dropdownlist's value, it should also change in the gridview. i have taken a label in the gridview's header template named "lbl_mnth" my dropdownlist's id is "ddl_mnth".
I have a problem with keeping the selected values in DropDownLists in rows in GridView while paging. I have this code behind:
private void RememberOldValues() { ArrayList LinijaIDList = new ArrayList(); int index = -1; foreach (GridViewRow row in GridView1.Rows) { index = (int)GridView1.DataKeys[row.RowIndex].Value; if (Session["equal_ITEMS"] != null) LinijaIDList = (ArrayList)Session["equal_ITEMS"]; if (row.Cells[0].Text == lineTextBox.Text) { if (!LinijaIDList.Contains(index)) LinijaIDList.Add(index); } else LinijaIDList.Remove(index); } if (LinijaIDList != null && LinijaIDList.Count > 0) Session["equal_ITEMS"] = LinijaIDList; } protected void Button1_Click(object sender, EventArgs e) { //Session["equal_ITEMS"] = null; RememberOldValues(); GridView1.AllowPaging = false; BindGrid(); //RePopulateValues(); DataTable dt = new DataTable(); dt.Columns.Add(new DataColumn("LinijaID", typeof(int))); dt.Columns.Add(new DataColumn("Ime", typeof(string))); ArrayList LinijaIDList = (ArrayList)Session["equal_ITEMS"]; //if (LinijaIDList!=null) //{ foreach (int LinijaID in LinijaIDList) { foreach (GridViewRow row in GridView1.Rows) { DropDownList Ime = GridView1.FooterRow.FindControl("ImeDropDownList") as DropDownList; int rowID = (int)GridView1.DataKeys[row.RowIndex].Value; //string Name = row.Cells[1].Text; string Name = Ime.SelectedValue; if (rowID == LinijaID) { DataRow dr = dt.NewRow(); dr["LinijaID"] = LinijaID; dr["Ime"] = Name; dt.Rows.Add(dr); } } } GridView1.AllowPaging = true; Session["equal1"] = dt; Response.Redirect("CheckedRowsPage1.aspx"); } // else //{ // GridView1.AllowPaging = true; // Session["equal1"]=null; // } }
When I insert a value in the TextBox2 and want to select only the rows from the GridView from different pages which have value in the first column the same as the value in the TextBox2, after clicking on Button1 I get this error:
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
